shell: reset noLock in the admin script dispatcher too

Three dispatchers reuse one CommandEnv: the interactive shell, the master's

third is exempt anyway because it calls ForceNoLock, so this changes nothing
today -- it keeps the rule the same everywhere rather than resting on that
exemption staying in place.

+possible entirely thanks to the support of these awesome [backers](https://github.com/seaweedfs/seaweedfs/blob/master/backers.md).
+If you'd like to grow SeaweedFS even stronger, please consider joining our
+<a href="https://www.patreon.com/seaweedfs">sponsors on Patreon</a>.
 
-One `weed` binary serves an S3 object store, a POSIX file system, and a lakehouse with S3 Tables, all over the same data. Each blob is one disk read away, capacity grows by starting another volume server, and cloud storage can be cached or tiered transparently.
+Your support will be really appreciated by me and other supporters!

 # Quick Start #
 
-## One command ##
 
-Download the latest binary from the [releases](https://github.com/seaweedfs/seaweedfs/releases/latest) page and unzip the single `weed` (or `weed.exe`) file, or let the install script put it in `/usr/local/bin`:
+## Quick Start with weed mini ##
 
-```bash
-curl -fsSL https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/install.sh | bash
-```
-
-Then start a ready-to-use S3 object store:
+Download the latest binary from https://github.com/seaweedfs/seaweedfs/releases and unzip the single `weed` (or `weed.exe`) file, or run `go install github.com/seaweedfs/seaweedfs/weed@latest`. Then start a ready-to-use S3 object store with credentials and a pre-created bucket in one command:
 
 ```bash
 AWS_ACCESS_KEY_ID=admin \
 AWS_SECRET_ACCESS_KEY=secret \
 S3_BUCKET=my-bucket \
-./weed mini -dir=./data
+./weed mini -dir=/data
 ```
 
-That's it. The S3 endpoint is at http://localhost:8333, `my-bucket` exists, and `admin`/`secret` are valid credentials:
+That's it — the S3 endpoint is at http://localhost:8333, `my-bucket` already exists, and `admin`/`secret` are valid credentials. `S3_BUCKET` accepts a comma-separated list (e.g. `raw,processed`); use `S3_TABLE_BUCKET` for S3 Tables buckets, each `name` or `name:FORMAT` where the format is `ICEBERG` (the default) or `LANCE`. Drop any of the env vars to skip that piece (no AWS keys → S3 runs in unauthenticated "Allow All" mode for development).
 
-```bash
-AWS_ACCESS_KEY_ID=admin AWS_SECRET_ACCESS_KEY=secret \
-  aws --endpoint-url http://localhost:8333 s3 cp README.md s3://my-bucket/
-```
-
-The same process also runs the master, a volume server, the filer, WebDAV, the Iceberg REST catalog, and the Admin UI. Add `S3_TABLE_BUCKET=warehouse` to also create an Iceberg table bucket, or `warehouse:LANCE` for a Lance one. Drop the AWS keys to run without authentication for development.
+The same command starts everything else too:
+- **S3 Endpoint**: http://localhost:8333
+- **Master UI**: http://localhost:9333
+- **Volume Server**: http://localhost:9340
+- **Filer UI**: http://localhost:8888
+- **WebDAV**: http://localhost:7333
+- **Admin UI**: http://localhost:23646
 
 > macOS: if the binary is quarantined, run `xattr -d com.apple.quarantine ./weed` first.
 
-`weed mini` is auto-tuned for one node and is fine for single-node production, such as an S3 gateway that issues presigned URLs. See [Quick Start with weed mini][WeedMini].
+Perfect for development, testing, learning SeaweedFS, and single-node deployments. To scale out, add more volume servers by running `weed volume -dir="/some/data/dir2" -master="<master_host>:9333" -port=8081` locally, on another machine, or on thousands of machines.
 
-## Docker ##
+## Quick Start for S3 API on Docker ##
 
 ```bash
-docker run -p 8333:8333 -v weed-data:/data \
+docker run -p 8333:8333 \
   -e AWS_ACCESS_KEY_ID=admin \
   -e AWS_SECRET_ACCESS_KEY=secret \
   -e S3_BUCKET=my-bucket \
   chrislusf/seaweedfs
 ```
 
-Same behavior as the `weed mini` command above.
+Same behavior as the `weed mini` command above — the S3 endpoint is at http://localhost:8333 with `my-bucket` pre-created. Drop the env vars to run anonymously for development.
 
-## Docker Compose ##
+# Introduction #
 
-To run master, volume server, filer, S3, and WebDAV as separate services:
+SeaweedFS is a simple and highly scalable distributed file system. There are two objectives:
 
-```bash
-wget https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/docker/seaweedfs-compose.yml
-wget -P prometheus https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/docker/prometheus/prometheus.yml
-docker compose -f seaweedfs-compose.yml -p seaweedfs up
-```
+1. to store billions of files!
+2. to serve the files fast!
 
-[Docker Compose for S3][DockerComposeS3] adds credentials, and the [docker/compose](docker/compose) folder has variants for replication, mounts, message queues, and more.
+SeaweedFS started as a blob store to handle small files efficiently. 
+Instead of managing all file metadata in a central master, 
+the central master only manages volumes on volume servers, 
+and these volume servers manage files and their metadata. 
+This relieves concurrency pressure from the central master and spreads file metadata into volume servers, 
+allowing faster file access (O(1), usually just one disk read operation).
 
-## Kubernetes with Helm ##
+There is only 40 bytes of disk storage overhead for each file's metadata. 
+It is so simple with O(1) disk reads that you are welcome to challenge the performance with your actual use cases.
 
-```bash
-helm repo add seaweedfs https://seaweedfs.github.io/seaweedfs/helm
-helm install seaweedfs seaweedfs/seaweedfs -n seaweedfs --create-namespace -f values.yaml
-```
+SeaweedFS started by implementing [Facebook's Haystack design paper](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf). 
+Also, SeaweedFS implements erasure coding with ideas from 
+[f4: Facebook’s Warm BLOB Storage System](https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf), and has a lot of similarities with [Facebook’s Tectonic Filesystem](https://www.usenix.org/system/files/fast21-pan.pdf) and [Google's Colossus File System](https://cloud.google.com/blog/products/storage-data-transfer/a-peek-behind-colossus-googles-file-system)
 
-A production-shaped `values.yaml` for a three-node cluster: two copies of every write, three masters, and an S3 endpoint with credentials and a bucket.
+On top of the blob store, optional [Filer] can support directories and POSIX attributes. 
+Filer is a separate linearly-scalable stateless server with customizable metadata stores, 
+e.g., MySql, Postgres, Redis, Cassandra, HBase, Mongodb, Elastic Search, LevelDB, RocksDB, Sqlite, MemSql, TiDB, Etcd, CockroachDB, YDB, etc.
 
-```yaml
-global:
-  seaweedfs:
-    enableReplication: true
-    replicationPlacement: "001"   # one extra copy on another server; "002" for two
+SeaweedFS can transparently integrate with the cloud. 
+With hot data on local cluster, and warm data on the cloud with O(1) access time, 
+SeaweedFS can achieve both fast local access time and elastic cloud storage capacity.
+What's more, the cloud storage access API cost is minimized. 
+Faster and cheaper than direct cloud storage!

-```
-
-The S3 endpoint is the `seaweedfs-s3` service on port 8333. [Helm Chart Recipes][HelmRecipes] has values for a development cluster, a lakehouse with the Iceberg catalog exposed, filer metadata on PostgreSQL, and node-local disks. The [SeaweedFS Operator][Operator] and the [CSI driver][SeaweedFsCsiDriver] are the other Kubernetes paths.
-
-## Build from source ##
-
-```bash
-git clone https://github.com/seaweedfs/seaweedfs.git
-cd seaweedfs/weed && make install
-```
-
-`weed` lands in `$GOPATH/bin`. [Getting Started][GettingStarted] covers running master, volume, filer, and S3 as separate processes.
-
-## Scale out ##
-
-Capacity is a volume server. Start one on any machine with disk and point it at the master:
-
-```bash
-weed volume -dir=/data -master=<master_host>:9333
-```
-
-Nothing rebalances until you ask it to. Throughput is a filer or S3 gateway; they are stateless, so run as many as you need behind a load balancer. [Production Setup][ProductionSetup] walks through a multi-node cluster.
+SeaweedFS also ships a built-in **Iceberg REST Catalog**, turning the same cluster into a self-contained lakehouse.
+Spark, Trino, Dremio, DuckDB, and RisingWave can query Iceberg tables directly — no Hive Metastore, Glue, or
+external catalog service required. Storage and table metadata live in one system, simplifying on-prem and
+small-team analytics stacks.

-# Why SeaweedFS #
-
-## Fast ##
-
-* One disk read per blob. A small file is one blob; a large file is split into chunks of a few MB, each its own blob. A volume server keeps a 16-byte index entry per blob in memory and reads it in a single seek, also for erasure-coded data.
-* The master is not in the read path. Clients cache the volume-to-server mapping and talk to volume servers directly.
-* 40 bytes of metadata per file on disk. Small files are packed into append-only volume files, so there is no per-file inode, no per-file metadata file, no fragmentation, and writes are SSD friendly.
-* Hot data is replicated; [erasure coding][ErasureCoding] is applied to warm data in the background, so writes never pay the encoding cost.
-* The [Rust volume server][RustVolume] is a drop-in for higher throughput and lower tail latency on the same on-disk format.
-
-On one laptop, [`weed benchmark`][Benchmarks] writes 1KB files at 15,700 per second and reads them back at 47,000 per second, and a mixed S3 [warp][S3Benchmark] run totals 3.2 GiB/s. Numbers are in the [Benchmark](#benchmark) section; throughput grows with volume servers and gateways.
-
-## Scalable ##
-
-* The master tracks volumes, not files. A cluster with billions of files has a few thousand volumes, so the master stays small. One master is enough for most clusters; run three for [Raft failover][FailoverMaster].
-* Adding a server adds capacity with no data reshuffle. Balancing, vacuum, erasure coding, and repair run on demand from [`weed shell`][WeedShell] or the [maintenance worker][Worker].
-* Filer and S3 gateways are stateless and scale linearly. Directory metadata lives in a [store you already run][FilerStores]: LevelDB, RocksDB, SQLite, MySQL, PostgreSQL, Cassandra, HBase, MongoDB, Redis, Elasticsearch, etcd, TiKV, FoundationDB, YDB, ArangoDB, Tarantool, and MySQL or PostgreSQL compatible databases such as TiDB, CockroachDB, and MemSQL.
-* Rack and data center aware [replication][Replication], [tiered storage][TieredStorage] across disk types, and [transparent cloud tiering][CloudTier] for unlimited capacity.
-* Files from a byte to [tens of TB][SuperLargeFiles]. Volumes up to 8TB with the large-disk build.
-
-## The most complete S3 API ##
-
-The S3 gateway implements the object, bucket, S3 Tables, IAM, and STS APIs on one endpoint, so the AWS SDKs and CLI, rclone, restic, Spark, and Trino work unchanged.
-
-| API | Operations |
-| --- | --- |
-| S3 bucket and object | 73 |
-| S3 Tables | 36 |
-| IAM | 39 |
-| STS | 5 |
-
-* [Versioning][Versioning], [Object Lock][ObjectLock] with retention and legal hold, [lifecycle][Lifecycle] rules, tagging, [CORS][CORS], [conditional reads and writes][ConditionalOps], checksums, presigned URLs, browser POST uploads, multipart uploads, and an atomic [RenameObject][RenameObject].
-* [Bucket policies][BucketPolicies] with [conditions][PolicyConditions] and [variables][PolicyVariables]; IAM users, groups, and policies; STS with [OIDC][OIDC], LDAP, and [Kubernetes service accounts][K8sSA].
-* [SSE-S3, SSE-KMS, and SSE-C][SSE] server-side encryption, with OpenBao and Vault, AWS KMS, Azure Key Vault, and GCP KMS as key providers.
-* [Audit log][AuditLog], [bucket quota][BucketQuota], and [rate limiting][RateLimiting].
-* Each bucket is its own collection, so deleting a bucket is instant.
-
-The full operation list is in [Amazon S3 API][AmazonS3API], and [Supported APIs vs MinIO][S3vsMinio] compares. The S3 compatibility suite and the SDK, IAM, SSE, policy, and Spark integration tests run in CI on every change.
-
-## A data warehouse with S3 Tables ##
-
-SeaweedFS is a lakehouse in one system. [S3 Table Buckets][S3TableBucket] hold Apache Iceberg tables by default, or [Lance][LanceCatalog] tables for vectors and multimodal data, and the built-in [Iceberg REST Catalog][IcebergCatalog] and Lance namespace serve them directly. There is no Hive Metastore, Glue, or separate catalog service to deploy, secure, and back up.
-
-* Query engines operate on the same tables at the same time: [Spark][SparkIceberg], [Trino][TrinoIceberg], [Dremio][DremioIceberg], [DuckDB][DuckDBIceberg], [Apache Doris][DorisIceberg], [RisingWave][RisingWaveIceberg], ClickHouse, and [LanceDB][LanceDB]. Catalog commits are atomic compare-and-swap, so concurrent writers are safe. [Lakekeeper][Lakekeeper] can front the same storage with STS-vended credentials.
-* [Automated table maintenance][IcebergMaintenance]: compaction, snapshot expiration, orphan file removal, and manifest rewriting, configured per bucket or table through the S3 Tables maintenance APIs, and the same for [Lance][LanceMaintenance].
-* IAM at the bucket, namespace, and table level with standard bucket policies, see [S3 Tables Security][S3TablesSecurity].
-* A [Hadoop compatible file system][Hadoop] for Spark, Flink, and HBase.
-
-`S3_TABLE_BUCKET=warehouse ./weed mini -dir=./data` brings the whole stack up on a laptop.
-
-## A fast cache for cloud storage ##
-
-[Cloud Drive][CloudDrive] mounts a bucket from S3, Google Cloud Storage, Azure, Backblaze B2, Wasabi, Storj, or any S3-compatible store into SeaweedFS and serves it at local speed:
-
-* Metadata is pulled once, so listing, stat, and directory walks cost no cloud API calls.
-* File content is downloaded once, on first read or [warmed][CacheRemote] by folder, name pattern, size, or age, and cached with the capacity of the whole cluster: cache everything, no churn.
-* Local writes complete at local latency and are written back to the cloud asynchronously in the cloud's native layout, so other tools keep reading the bucket directly.
-* Uncache by the same rules to free local disk while keeping the metadata.
-
-[Cloud Tier][CloudTier] goes the other direction, moving whole warm volumes to cloud storage while keeping one-read access, and the [Gateway to Remote Object Storage][GatewayToRemoteObjectStore] mirrors every bucket to a remote store. Faster and cheaper than reading the cloud directly.
-
-## Active-active replication and more ##
-
-* [Active-active or active-passive replication][ActiveActiveAsyncReplication] between clusters, continuous and resumable, for the whole tree or chosen folders, across data centers.
-* [Filer store replication][FilerStoreReplication] for metadata HA, [async backup][AsyncBackup] to cloud storage, [metadata backup][MetaBackup], and [change data capture][CDC] with [webhooks][Webhook] on every metadata event.
-* The same data as a [FUSE mount][Mount] on Linux, macOS, and [Windows][MountWindows], over [WebDAV][WebDAV], [SFTP][SFTP], HDFS, HTTP, and [TUS resumable uploads][TUS]; on Kubernetes through the [CSI driver][SeaweedFsCsiDriver] and [Operator][Operator].
-* [AES256-GCM encryption at rest][FilerDataEncryption], TLS and mTLS between components, JWT-signed volume access, and [FIPS][FIPS] builds.
-* [Admin UI][AdminUI], Prometheus [metrics][Metrics], [TTL][VolumeServerTTL] per file or volume, automatic compression and compaction, and [seaweed-up][SeaweedUp] for bare-metal clusters.
+# Features #
+## Additional Blob Store Features ##
+* Support different replication levels, with rack and data center aware.
+* Automatic master servers failover - no single point of failure (SPOF).
+* Automatic compression depending on file MIME type.
+* Automatic compaction to reclaim disk space after deletion or update.
+* [Automatic entry TTL expiration][VolumeServerTTL].
+* Flexible Capacity Expansion: Any server with some disk space can add to the total storage space.

+* Optional picture resizing.
+* Support ETag, Accept-Range, Last-Modified, etc.
+* Support in-memory/leveldb/readonly mode tuning for memory/performance balance.
+* Support rebalancing the writable and readonly volumes.
+* [Customizable Multiple Storage Tiers][TieredStorage]: Customizable storage disk types to balance performance and cost.
+* [Transparent cloud integration][CloudTier]: unlimited capacity via tiered cloud storage for warm data.
+* [Erasure Coding for warm storage][ErasureCoding]  Rack-Aware 10.4 erasure coding reduces storage cost and increases availability. Enterprise version can customize EC ratio.

+* [Automated table maintenance][IcebergMaintenance]: compaction, snapshot expiration, orphan removal, manifest rewriting.
+* Granular IAM at the bucket, namespace, and table level via standard S3 bucket policies.
 
-* **Master** servers, one or a Raft group of three, track which volume lives on which volume server and hand out file ids. They are not in the read path.
-* **Volume** servers store blobs in append-only volume files, keep a 16-byte in-memory index per blob, and replicate or erasure-code at the volume level.
-* **Filer** servers add directories and files on top, with metadata in a store of your choice, and expose HTTP, S3, WebDAV, SFTP, FUSE, and the table catalogs.

-The blob store started from [Facebook's Haystack](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf), erasure coding takes ideas from [f4](https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf), and the whole has a lot in common with [Tectonic](https://www.usenix.org/system/files/fast21-pan.pdf) and [Colossus](https://cloud.google.com/blog/products/storage-data-transfer/a-peek-behind-colossus-googles-file-system). How file ids are assigned, written, and looked up, and why a master that tracks volumes scales, is in [Blob Store Architecture][BlobStoreArchitecture]; the services are in [Components][Components] and the [white paper][WhitePaper].

-# Compared to Other Systems #
+## Example: Using Seaweed Blob Store ##
+
+By default, the master node runs on port 9333, and the volume nodes run on port 8080.
+Let's start one master node, and two volume nodes on port 8080 and 8081. Ideally, they should be started from different machines. We'll use localhost as an example.
+
+SeaweedFS uses HTTP REST operations to read, write, and delete. The responses are in JSON or JSONP format.
+
+### Start Master Server ###
+
+```
+> ./weed master
+```
+
+### Start Volume Servers ###
+
+```
+> weed volume -dir="/tmp/data1" -max=5  -master="localhost:9333" -port=8080 &
+> weed volume -dir="/tmp/data2" -max=10 -master="localhost:9333" -port=8081 &
+```
+
+### Write A Blob ###
+
+A blob, also referred as a needle, a chunk, or mistakenly as a file, is just a byte array. It can have attributes, such as name, mime type, create or update time, etc. But basically it is just a byte array of a relatively small size, such as 2 MB ~ 64 MB. The size is not fixed.
+
+To upload a blob: first, send a HTTP POST, PUT, or GET request to `/dir/assign` to get an `fid` and a volume server URL:
+
+```
+> curl http://localhost:9333/dir/assign
+{"count":1,"fid":"3,01637037d6","url":"127.0.0.1:8080","publicUrl":"localhost:8080"}
+```
+
+Second, to store the blob content, send a HTTP multi-part POST request to `url + '/' + fid` from the response:
+
+```
+> curl -F file=@/home/chris/myphoto.jpg http://127.0.0.1:8080/3,01637037d6
+{"name":"myphoto.jpg","size":43234,"eTag":"1cc0118e"}
+```
+
+To update, send another POST request with updated blob content.
+
+For deletion, send an HTTP DELETE request to the same `url + '/' + fid` URL:
+
+```
+> curl -X DELETE http://127.0.0.1:8080/3,01637037d6
+```
+
+### Save Blob Id ###
+
+Now, you can save the `fid`, 3,01637037d6 in this case, to a database field.
+
+The number 3 at the start represents a volume id. After the comma, it's one file key, 01, and a file cookie, 637037d6.
+
+The volume id is an unsigned 32-bit integer. The file key is an unsigned 64-bit integer. The file cookie is an unsigned 32-bit integer, used to prevent URL guessing.
+
+The file key and file cookie are both coded in hex. You can store the <volume id, file key, file cookie> tuple in your own format, or simply store the `fid` as a string.
+
+If stored as a string, in theory, you would need 8+1+16+8=33 bytes. A char(33) would be enough, if not more than enough, since most uses will not need 2^32 volumes.
+
+If space is really a concern, you can store the file id in the binary format. You would need one 4-byte integer for volume id, 8-byte long number for file key, and a 4-byte integer for the file cookie. So 16 bytes are more than enough.
+
+### Read a Blob ###
+
+Here is an example of how to render the URL.
+
+First look up the volume server's URLs by the file's volumeId:
+
+```
+> curl http://localhost:9333/dir/lookup?volumeId=3
+{"volumeId":"3","locations":[{"publicUrl":"localhost:8080","url":"localhost:8080"}]}
+```
+
+Since (usually) there are not too many volume servers, and volumes don't move often, you can cache the results most of the time. Depending on the replication type, one volume can have multiple replica locations. Just randomly pick one location to read.
+
+Now you can take the public URL, render the URL or directly read from the volume server via URL:
+
+```
+ http://localhost:8080/3,01637037d6.jpg
+```
+
+Notice we add a file extension ".jpg" here. It's optional and just one way for the client to specify the file content type.
+
+If you want a nicer URL, you can use one of these alternative URL formats:
+
+```
+ http://localhost:8080/3/01637037d6/my_preferred_name.jpg
+ http://localhost:8080/3/01637037d6.jpg
+ http://localhost:8080/3,01637037d6.jpg
+ http://localhost:8080/3/01637037d6
+ http://localhost:8080/3,01637037d6
+```
+
+If you want to get a scaled version of an image, you can add some params:
+
+```
+http://localhost:8080/3/01637037d6.jpg?height=200&width=200
+http://localhost:8080/3/01637037d6.jpg?height=200&width=200&mode=fit
+http://localhost:8080/3/01637037d6.jpg?height=200&width=200&mode=fill
+```
+
+### Rack-Aware and Data Center-Aware Replication ###
+
+SeaweedFS applies the replication strategy at a volume level. So, when you are getting a blob id, you can specify the replication strategy. For example:
+
+```
+curl http://localhost:9333/dir/assign?replication=001
+```
+
+The replication parameter options are:
+
+```
+000: no replication
+001: replicate once on the same rack
+010: replicate once on a different rack, but same data center
+100: replicate once on a different data center
+200: replicate twice on two different data center
+110: replicate once on a different rack, and once on a different data center
+```
+
+More details about replication can be found [on the wiki][Replication].
+
+[Replication]: https://github.com/seaweedfs/seaweedfs/wiki/Replication
+
+You can also set the default replication strategy when starting the master server.
+
+### Allocate Blob Key on Specific Data Center ###
+
+Volume servers can be started with a specific data center name:
+
+```
+ weed volume -dir=/tmp/1 -port=8080 -dataCenter=dc1
+ weed volume -dir=/tmp/2 -port=8081 -dataCenter=dc2
+```
+
+When requesting a blob key, an optional "dataCenter" parameter can limit the assigned volume to the specific data center. For example, this specifies that the assigned volume should be limited to 'dc1':
+
+```
+ http://localhost:9333/dir/assign?dataCenter=dc1
+```

+
+## Blob Store Architecture ##
+
+Usually distributed file systems split each file into chunks. A central server keeps a mapping of filenames to chunks, and also which chunks each chunk server has.
+
+The main drawback is that the central server can't handle many small files efficiently, and since all read requests need to go through the central master, so it might not scale well for many concurrent users.
+
+Instead of managing chunks, SeaweedFS manages data volumes in the master server. Each data volume is 32GB in size, and can hold a lot of blobs. And each storage node can have many data volumes. So the master node only needs to store the metadata about the volumes, which is a fairly small amount of data and is generally stable.
+
+The actual blob metadata, which are the blob volume, offset, and size, is stored in each volume on volume servers. Since each volume server only manages metadata of blobs on its own disk, with only 16 bytes for each blob, all access can read the metadata just from memory and only needs one disk operation to actually read file data.
+
+For comparison, consider that an xfs inode structure in Linux is 536 bytes.
+
+### Master Server and Volume Server ###
+
+The architecture is fairly simple. The actual data is stored in volumes on storage nodes. One volume server can have multiple volumes, and can both support read and write access with basic authentication.
+
+All volumes are managed by a master server. The master server contains the volume id to volume server mapping. This is fairly static information, and can be easily cached.
+
+On each write request, the master server also generates a file key, which is a growing 64-bit unsigned integer. Since write requests are not generally as frequent as read requests, one master server should be able to handle the concurrency well.
+
+### Write and Read files ###
+
+When a client sends a write request, the master server returns (volume id, file key, file cookie, volume node URL) for the blob. The client then contacts the volume node and POSTs the blob content.
+
+When a client needs to read a blob based on (volume id, file key, file cookie), it asks the master server by the volume id for the (volume node URL, volume node public URL), or retrieves this from a cache. Then the client can GET the content, or just render the URL on web pages and let browsers fetch the content.
+
+### Saving memory ###
+
+All blob metadata stored on a volume server is readable from memory without disk access. Each file takes just a 16-byte map entry of <64bit key, 32bit offset, 32bit size>. Of course, each map entry has its own space cost for the map. But usually the disk space runs out before the memory does.
+
+### Tiered Storage to the cloud ###
+
+The local volume servers are much faster, while cloud storages have elastic capacity and are actually more cost-efficient if not accessed often (usually free to upload, but relatively costly to access). With the append-only structure and O(1) access time, SeaweedFS can take advantage of both local and cloud storage by offloading the warm data to the cloud.
+
+Usually hot data are fresh and warm data are old. SeaweedFS puts the newly created volumes on local servers, and optionally upload the older volumes on the cloud. If the older data are accessed less often, this literally gives you unlimited capacity with limited local servers, and still fast for new data. 
+
+With the O(1) access time, the network latency cost is kept at minimum. 
+
+If the hot/warm data is split as 20/80, with 20 servers, you can achieve storage capacity of 100 servers. That's a cost saving of 80%! Or you can repurpose the 80 servers to store new data also, and get 5X storage throughput.

+
+### Hard Drive Performance ###
+
+When testing read performance on SeaweedFS, it basically becomes a performance test of your hard drive's random read speed. Hard drives usually get 100MB/s~200MB/s.
+
+### Solid State Disk ###
+
+To modify or delete small files, SSD must delete a whole block at a time, and move content in existing blocks to a new block. SSD is fast when brand new, but will get fragmented over time and you have to garbage collect, compacting blocks. SeaweedFS is friendly to SSD since it is append-only. Deletion and compaction are done on volume level in the background, not slowing reading and not causing fragmentation.

-# SeaweedFS as an Apache CloudStack Object Storage Provider
-
-A CloudStack ObjectStore plugin that makes SeaweedFS a first-class object storage
-backend inside Apache CloudStack, alongside the existing MinIO and Ceph RGW
-providers. This is a collaboration with proIO (Swen), who builds private clouds on
-CloudStack and wants SeaweedFS as a storage option.
-
-## The request
-
-> We can only add MinIO and Ceph as object storage [in CloudStack] today. I want
-> to get SeaweedFS into this project... What we need is to build a provider which
-> does the communication between Cloudstack and SeaweedFS.
-
-This is **not** a SeaweedFS-side feature. The work lives in the Apache CloudStack
-repo (Java): a new plugin under `plugins/storage/object/seaweedfs/` that implements
-CloudStack's ObjectStore plugin framework and talks to SeaweedFS over its S3 and
-IAM APIs. SeaweedFS itself needs no changes for the core to work — its S3 API
-already covers every bucket operation CloudStack requires, and its IAM API covers
-user/credential management.
-
-## How the CloudStack ObjectStore framework works
-
-CloudStack 4.18+ introduced an Object Storage framework. An admin registers an
-object storage pool via `addObjectStoragePool` (URL + provider + credentials);
-tenants then create and manage buckets on it through CloudStack APIs. CloudStack
-manages pool and bucket lifecycle; the underlying provider handles the actual
-object protocol.
-
-A provider is a plugin module implementing three interfaces:
-
-### 1. `ObjectStoreProvider` — registration
-
-`MinIOObjectStoreProviderImpl` is the reference. It is a Spring `@Component` that:
-- Returns a provider name (`"MinIO"`)
-- Returns `DataStoreProviderType.OBJECT`
-- In `configure()`, injects the lifecycle and driver implementations and calls
-  `storeMgr.registerDriver(name, driver)`
-
-### 2. `ObjectStoreLifeCycle` — pool add/remove
-
-`MinIOObjectStoreLifeCycleImpl.initialize()` reads the URL, name, and
-`accesskey`/`secretkey` details from the `addObjectStoragePool` call, tests the
-connection by listing buckets, and persists an `ObjectStoreVO` via
-`ObjectStoreHelper`. The other methods (attachCluster/Host/Zone, maintain,
-deleteDataStore) are no-ops for object storage.
-
-### 3. `ObjectStoreDriver` — bucket + user operations
-
-`ObjectStoreDriver` (in `engine/storage/.../object/ObjectStoreDriver.java`) extends
-`DataStoreDriver` and defines the bucket/user contract. Every provider must
-implement:
-
-| Method | Purpose |
-| --- | --- |
-| `createBucket(Bucket, boolean objectLock)` | Create a bucket |
-| `listBuckets(long storeId)` | List all buckets |
-| `deleteBucket(BucketTO, long storeId)` | Delete a bucket |
-| `createUser(long accountId, long storeId)` | Provision a user + credentials for a CloudStack account |
-| `setBucketPolicy` / `getBucketPolicy` / `deleteBucketPolicy` | Bucket policy CRUD |
-| `setBucketEncryption` / `deleteBucketEncryption` | SSE config |
-| `setBucketVersioning` / `deleteBucketVersioning` | Versioning enable/suspend |
-| `setBucketQuota(BucketTO, long storeId, long size)` | Per-bucket quota |
-| `getAllBucketsUsage(long storeId)` | Usage map for billing/accounting |
-| `getBucketAcl` / `setBucketAcl` | ACLs (MinIO/Ceph return null / no-op) |
-
-`BaseObjectStoreDriverImpl` provides no-op defaults for the `DataStoreDriver`
-methods (`createAsync`, `deleteAsync`, `copyAsync`, `canCopy`, `resize`,
-`getTO`, `getStoreTO`), so object-store providers only implement the bucket/user
-methods above.
-
-## How the four existing providers differ (and where SeaweedFS lands)
-
-CloudStack ships four object-store providers. Three are relevant; the simulator
-is a test stub.
-
-| Concern | MinIO | Ceph RGW | Cloudian HyperStore | SeaweedFS |
-| --- | --- | --- | --- | --- |
-| Bucket CRUD | `MinioClient` (S3) | `AmazonS3` (AWS SDK v1) | `AmazonS3` (AWS SDK v1) | `AmazonS3` (AWS SDK v1) |
-| Bucket policy | `MinioClient` | `AmazonS3` | `AmazonS3` | `AmazonS3` |
-| Versioning | `MinioClient` | `AmazonS3` | `AmazonS3` | `AmazonS3` |
-| Encryption | `MinioClient` | not implemented | `AmazonS3` | `AmazonS3` |
-| **User creation** | `MinioAdminClient` | `RgwAdmin` | **`AmazonIdentityManagement`** | **`AmazonIdentityManagement`** |
-| **Per-bucket quota** | `MinioAdminClient` | `RgwAdmin` | **not supported** (throws) | **S3 extension** (`PUT /{bucket}?seaweedfs-quota`, SigV4, `s3:PutBucketQuota`) |
-| **Usage reporting** | `MinioAdminClient` | `RgwAdmin` | Cloudian admin API | S3 `ListObjectsV2` (MVP); Prometheus / SOSAPI `capacity.xml` (recommended) |
-
-**Cloudian HyperStore is the direct precedent.** It is an S3-compatible store
-that, like SeaweedFS, manages users via the **standard AWS IAM API** using the
-AWS IAM Java SDK (`com.amazonaws.services.identitymanagement`). Its driver
-(`CloudianHyperStoreObjectStoreDriverImpl`) and util
-(`CloudianHyperStoreUtil`) are the template this design follows almost line for
-line. Cloudian even validates the quota limitation the same way this design
-proposes for the MVP: `setBucketQuota` throws for any non-zero size and only
-accepts `0` (no quota).
-
-The SeaweedFS plugin is therefore a **simpler Cloudian** — same AWS S3 + IAM SDK
-clients, same store-details keys (`s3Url`, `iamUrl`, `accesskey`, `secretkey`),
-same IAM-user-with-restricted-policy pattern, but with no proprietary admin
-client at all (Cloudian has its own `CloudianClient` for its admin API; SeaweedFS
-needs only S3 + IAM). For quota, the plugin uses a narrow SeaweedFS S3 extension
-(see below); for usage reporting, it falls back to S3 `ListObjectsV2` in the MVP
-and recommends Prometheus or SOSAPI `capacity.xml` for production scale.
-
-### Quota via the S3 `?seaweedfs-quota` extension
-
-SeaweedFS supports bucket quota natively (server-side enforcement via a
-read-only flag when usage exceeds the limit). Rather than exposing the broad
-admin REST API (which would require a global bearer token and grant cluster-wide
-admin access), the integration uses a **narrow, scoped S3 subresource**:
-
-- `PUT /{bucket}?seaweedfs-quota` — set bucket quota (IAM permission `s3:PutBucketQuota`)
-- `GET /{bucket}?seaweedfs-quota` — get bucket quota (IAM permission `s3:GetBucketQuota`)
-
-**PUT request body** (JSON):
-```json
-{"quota_size": 100, "quota_unit": "GB", "quota_enabled": true}
-```
-
-**GET response body** (JSON):
-```json
-{"quota_size": 107374182400, "quota_unit": "B", "quota_enabled": true}
-```
-
-Note: GET always returns `quota_unit: "B"` and the absolute byte count, not
-the original unit. A disabled-but-retained quota returns a positive
-`quota_size` with `quota_enabled: false`.
-
-Quota is stored on the bucket's filer entry (positive = enabled, negative =
-disabled but retained, zero = no quota), matching the existing admin REST API
-behavior. When quota is cleared, the bucket's read-only flag is also lifted.
-
-**Authentication** uses the existing S3 SigV4 flow — no new global secret is
-needed. The CloudStack service credential (the `accesskey`/`secretkey` on the
-object store) is the admin credential used for all driver operations: bucket
-CRUD, IAM user provisioning, and quota management. It must have broad S3 and
-IAM permissions. The per-account IAM users created by `createUser` are the
-ones with restricted permissions (full S3 access except bucket
-creation/deletion). A future hardening could split quota management onto a
-separate credential scoped to only `s3:PutBucketQuota`/`s3:GetBucketQuota`,
-but the MVP uses the single admin credential for simplicity, matching how
-the MinIO and Ceph providers work.
-
-The plugin's `setBucketQuota` signs and sends the `PUT /{bucket}?seaweedfs-quota`
-request using the AWS SDK v1 `AWSS3V4Signer` for SigV4 signing, then sends the
-signed request via `java.net.http.HttpClient` (the AWS S3 SDK doesn't natively
-support custom subresources, so we sign manually and send the request
-ourselves). The `seaweedfs-quota` query parameter is included in the signed
-canonical query string.
-
-### Usage reporting
-
-`getAllBucketsUsage` must return a `Map<String, Long>` of bucket name → size.
-MinIO uses `MinioAdminClient.getDataUsageInfo`; Ceph uses
-`RgwAdmin.listBucketInfo`. SeaweedFS has no admin rollup endpoint, so the MVP
-plugin computes it by listing buckets and summing object sizes via S3
-`ListObjectsV2` — expensive for large stores.
-
-For production scale, SeaweedFS already exposes per-bucket size in:
-- **Prometheus metrics** (`bucket_size_bytes` gauge, refreshed every minute)
-- **SOSAPI `capacity.xml`** (reports capacity, available space, and usage
-  through the S3 endpoint)
-
-Operators should consume one of those instead of S3 list-based aggregation for
-large deployments. The MVP's list-based approach is correct but slow; flag it as
-a known limitation.
-
-## SeaweedFS API surface (what the plugin relies on)
-
-SeaweedFS exposes two relevant APIs, both AWS-compatible:
-
-### S3 API (`weed s3`)
-Full S3-compatible surface. Confirmed against the SeaweedFS S3 wiki and code:
-- `CreateBucket`, `HeadBucket`, `ListBuckets`, `DeleteBucket`
-- `PutBucketPolicy`, `GetBucketPolicy`, `DeleteBucketPolicy`
-- `PutBucketVersioning` (Enabled / Suspended), `GetBucketVersioning`
-- `PutBucketEncryption`, `GetBucketEncryption`, `DeleteBucketEncryption`
-- `PutBucketAcl`, `GetBucketAcl`
-- `ListObjectsV2`, `HeadObject`, `GetObject`, `PutObject`, `DeleteObject`
-- Bucket quota via extended attributes / `s3.bucket.quota` (enforced server-side,
-  surfaced as a read-only state when exceeded — see PR #10224)
-
-### IAM API (`weed iam` / `iamapi`)
-AWS IAM-compatible REST endpoints, implemented in `weed/iamapi/`. Confirmed by
-the test suite which uses the **AWS IAM SDK** (`aws-sdk-go/service/iam`) against
-the same handlers CloudStack would call:
-- `CreateUser`, `DeleteUser`, `ListUsers`, `GetUser`
-- `CreateAccessKey`, `DeleteAccessKey`, `ListAccessKeys`
-- `PutUserPolicy`, `GetUserPolicy`, `DeleteUserPolicy`
-- `AttachUserPolicy`, `ListAttachedUserPolicies`
-
-This means the CloudStack plugin can manage SeaweedFS users with the **AWS IAM
-Java SDK** (`com.amazonaws.services.identitymanagement.AmazonIdentityManagement`),
-exactly the way the AWS IAM Go SDK is used in SeaweedFS's own tests. No proprietary
-admin client is needed. **Cloudian HyperStore already does exactly this** in the
-CloudStack tree — the SeaweedFS plugin follows the same pattern.
-
-## Design
-
-### Module layout
-
-New CloudStack plugin module, mirroring `plugins/storage/object/cloudian/`
-(the closest precedent — same AWS S3 + IAM SDK approach):
-
-```
-plugins/storage/object/seaweedfs/
-  pom.xml
-  src/main/java/org/apache/cloudstack/storage/datastore/
-    driver/SeaweedFSObjectStoreDriverImpl.java
-    lifecycle/SeaweedFSObjectStoreLifeCycleImpl.java
-    provider/SeaweedFSObjectStoreProviderImpl.java
-    util/SeaweedFSObjectStoreUtil.java
-  src/test/java/org/apache/cloudstack/storage/datastore/
-    driver/SeaweedFSObjectStoreDriverImplTest.java
-    provider/SeaweedFSObjectStoreProviderImplTest.java
-  src/main/resources/META-INF/cloudstack/storage-object-seaweedfs/
-    module.properties
-    spring-storage-object-seaweedfs-context.xml
-```
-
-### `SeaweedFSObjectStoreProviderImpl`
-
-Direct copy of `MinIOObjectStoreProviderImpl` with `providerName = "SeaweedFS"`,
-injecting the SeaweedFS lifecycle and driver. Registers via
-`storeMgr.registerDriver`.
-
-### `SeaweedFSObjectStoreLifeCycleImpl`
-
-Copy of `MinIOObjectStoreLifeCycleImpl`. `initialize()` reads `url`, `name`,
-`accesskey`, `secretkey` from the `addObjectStoragePool` details map, tests the
-connection by calling `AmazonS3.listBuckets()` against the SeaweedFS S3 endpoint,
-and persists the `ObjectStoreVO`. No proprietary client needed — the AWS S3 SDK
-is enough for the health check.
-
-### `SeaweedFSObjectStoreDriverImpl`
-
-The substantive class. Uses two AWS SDK v1 clients (same dependency Ceph already
-pulls in, so no new CloudStack dependency):
-
-- `AmazonS3` for bucket operations (path-style, endpoint-pinned, `us-east-1`
-  region placeholder — same as Ceph's `getS3Client`)
-- `AmazonIdentityManagement` for user/credential operations, pointed at the
-  SeaweedFS IAM endpoint
-
-#### Bucket operations — straightforward S3
-
-| Interface method | Implementation |
-| --- | --- |
-| `createBucket` | `s3.createBucket(name)`; reject if `doesBucketExistV2`; persist access/secret key + URL on `BucketVO` (same as Ceph) |
-| `listBuckets` | `s3.listBuckets()` → wrap as `BucketObject` (same as Ceph) |
-| `deleteBucket` | `s3.deleteBucket(name)` (same as Ceph) |
-| `setBucketPolicy` | `s3.setBucketPolicy(...)` with the same public/private JSON the MinIO/Ceph drivers build |
-| `getBucketPolicy` / `deleteBucketPolicy` | `s3.getBucketPolicy` / `s3.deleteBucketPolicy` |
-| `setBucketVersioning` | `s3.setBucketVersioningConfiguration(Enabled)` |
-| `deleteBucketVersioning` | `s3.setBucketVersioningConfiguration(Suspended)` |
-| `setBucketEncryption` | `s3.setBucketEncryptionConfiguration(SSE-S3 rule)` |
-| `deleteBucketEncryption` | `s3.deleteBucketEncryptionConfiguration` |
-| `getBucketAcl` / `setBucketAcl` | no-op / null (same as MinIO and Ceph) |
-
-#### User creation — the key difference
-
-MinIO calls `MinioAdminClient.addUser`; Ceph calls `RgwAdmin.createUser`. SeaweedFS
-exposes the standard AWS IAM API, so the plugin calls:
-
-```java
-AmazonIdentityManagement iam = getIamClient(storeId);
-String userName = "acs-" + account.getUuid();
-
-// CreateUser (idempotent — check GetUser first, like Ceph does)
-iam.createUser(new CreateUserRequest(userName));
-
-// CreateAccessKey → returns the access key + secret key to persist
-CreateAccessKeyResult result = iam.createAccessKey(
-    new CreateAccessKeyRequest().withUserName(userName));
-AccessKey key = result.getAccessKey();
-
-// Persist per-account, same pattern as Ceph's CEPH_ACCESS_KEY/CEPH_SECRET_KEY
-details.put(SEAWEEDFS_ACCESS_KEY, key.getAccessKeyId());
-details.put(SEAWEEDFS_SECRET_KEY, key.getSecretAccessKey());
-_accountDetailsDao.persist(accountId, details);
-```
-
-This is the cleanest mapping of the three providers: no proprietary admin client,
-just the AWS IAM SDK that CloudStack already has access to. The IAM endpoint URL
-is provided as `iamUrl` in the store details. If `iamUrl` is omitted, the driver
-defaults it to `s3Url` — SeaweedFS registers its embedded IAM API at `POST /` on
-the same S3 endpoint (`UnifiedPostHandler` in `s3api_server.go`), so the IAM
-endpoint is the same as the S3 endpoint unless the deployment runs a separate
-`weed iam` server.
-
-#### Bucket quota — S3 `?seaweedfs-quota` extension
-
-This is the one genuine gap. MinIO and Ceph both have an admin API to set a
-per-bucket quota that the backend enforces. SeaweedFS enforces bucket quota
-server-side, but the configuration path was **not exposed over a standard S3 or
-IAM API** — it was only set via the admin REST API or shell commands.
-
-The integration adds a **narrow S3 subresource** to SeaweedFS:
-- `PUT /{bucket}?seaweedfs-quota` — set bucket quota (IAM permission `s3:PutBucketQuota`)
-- `GET /{bucket}?seaweedfs-quota` — get bucket quota (IAM permission `s3:GetBucketQuota`)
-
-This is implemented in SeaweedFS PR #11279. It uses SigV4 authentication and
-dedicated IAM permissions, so the CloudStack service credential can be scoped
-to quota management only — no global admin token, no cluster-wide admin access.
-The enforcement already exists (PR #10224); this PR only adds the HTTP
-configuration surface.
-
-An earlier approach (PR #11278, closed) added bearer-token auth to the broad
-admin REST API. After review, that was unnecessary for this integration —
-static S3 config plus standard S3 APIs plus one scoped quota mutation API is
-sufficient and far safer.
-
-> **Note on AWS tools compatibility.** `?seaweedfs-quota` is a SeaweedFS-specific
-> S3 subresource, not part of the AWS S3 API. Standard AWS tools (`aws s3api`,
-> `s3cmd`, `rclone`) cannot call it directly. This is the same limitation MinIO
-> and Ceph have — MinIO quota lives behind a separate admin API (`mc admin
-> bucket quota`), and Ceph quota lives behind the Admin Ops API
-> (`radosgw-admin quota set`). Neither is callable via `aws s3api` either.
-> SeaweedFS's approach is the closest to standard S3 because it uses the same
-> endpoint and same SigV4 credentials, just with a custom query parameter.
-> Interactive quota management remains available via `weed shell`; the S3
-> extension exists for programmatic integration (CloudStack) where the
-> integrator can sign SigV4 requests but cannot run shell commands.
-
-#### Usage reporting
-
-`getAllBucketsUsage` must return a `Map<String, Long>` of bucket name → size.
-MinIO uses `MinioAdminClient.getDataUsageInfo`; Ceph uses
-`RgwAdmin.listBucketInfo`. SeaweedFS has no admin rollup endpoint, so the MVP
-plugin computes it by listing buckets and summing object sizes via S3
-`ListObjectsV2` — expensive for large stores. Better options exist in
-SeaweedFS already:
-- **Prometheus metrics** (`bucket_size_bytes` gauge, refreshed every minute)
-- **SOSAPI `capacity.xml`** (reports capacity, available space, and usage
-  through the S3 endpoint — note: the current "return zero on backend error"
-  behavior should be validated before using it for billing)
-
-For the MVP, `listBuckets` + per-bucket size via the S3 API is correct but slow;
-flag it as a known limitation. Operators should consume Prometheus or SOSAPI
-for production-scale usage reporting.
-
-### Spring wiring
-
-`spring-storage-object-seaweedfs-context.xml` registers the provider bean,
-identical to the MinIO one. `module.properties` sets
-`name=storage-object-seaweedfs`, `parent=storage`.
-
-### `pom.xml`
-
-Depends on `aws-java-sdk-s3` and `aws-java-sdk-iam` — both already in the
-CloudStack dependency tree (Ceph uses the S3 SDK; the IAM SDK is the standard AWS
-bundle). No new third-party dependency, unlike MinIO which pulls in the MinIO
-Java client.
-
-## What changes on the SeaweedFS side
-
-**One narrow S3 extension is required for quota management.** SeaweedFS PR #11279
-adds the `?seaweedfs-quota` S3 subresource:
-
-- `PUT /{bucket}?seaweedfs-quota` — set bucket quota (IAM permission `s3:PutBucketQuota`)
-- `GET /{bucket}?seaweedfs-quota` — get bucket quota (IAM permission `s3:GetBucketQuota`)
-
-This is authenticated via standard S3 SigV4 and authorized via dedicated IAM
-permissions, so no global admin token is needed. The enforcement already exists
-(PR #10224); this PR only adds the HTTP configuration surface.
-
-One follow-up improvement on the SeaweedFS side would close the usage reporting
-gap:
-
-1. **Validate SOSAPI `capacity.xml` usage calculation** — the current "return
-   zero on backend error" behavior should be validated before using it for
-   billing. If reliable, CloudStack can consume it directly instead of
-   list-based aggregation.
-
-## Open questions for proIO / Swen
-
-1. **IAM endpoint path.** ~~Where does `weed iam` listen relative to the S3
-   endpoint in a typical proIO deployment?~~ **Resolved.** SeaweedFS registers
-   its embedded IAM API at `POST /` on the same S3 endpoint
-   (`UnifiedPostHandler`), so the driver defaults `iamUrl` to `s3Url`. A
-   separate `iamUrl` is only needed if the deployment runs a standalone
-   `weed iam` server on a different host/port.
-2. **Quota requirements.** Do proIO's customers need server-enforced per-bucket
-   quotas, or is CloudStack-side accounting sufficient for the first release?
-   The `?seaweedfs-quota` S3 extension (PR #11279) provides server-enforced
-   quotas via a scoped credential; this is the recommended path.
-3. **Object Lock.** `createBucket` takes an `objectLock` boolean. MinIO supports
-   it; Ceph ignores it. SeaweedFS has Object Lock support. Should the plugin pass
-   it through?

-   `apache/cloudstack` themselves (with SeaweedFS maintainers as reviewers), or

-## Verify an image signature
-
-Every image CI pushes to `chrislusf/seaweedfs` and `ghcr.io/chrislusf/seaweedfs` is signed with [cosign](https://docs.sigstore.dev/cosign/verifying/verify/), keyless, by the GitHub Actions workflow that built it, so there is no key to fetch or pin. The signature is attached to the image digest and covers the multi-arch index and each platform image in it; `latest` is the release image under another tag and verifies the same way. Images published before September 2026 predate signing.
-
-```bash
-cosign verify \
-  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
-  --certificate-identity-regexp '^https://github.com/seaweedfs/seaweedfs/\.github/workflows/container_release_unified\.yml@' \
-  chrislusf/seaweedfs:latest
-```
-
-cosign prints the digest it verified. Deploy by that digest, or let an admission controller resolve the tag, so what runs is what was checked.
-
-The identity is `https://github.com/seaweedfs/seaweedfs/.github/workflows/<workflow>@<ref>`. The ref is `refs/tags/<version>` for a release and `refs/heads/master` when a variant was republished by hand. The workflow is `container_release_unified.yml` for the release images, `container_dev.yml` for `dev`, `container_latest.yml` for a `latest` rebuilt by hand, `container_release_foundationdb.yml` for the `_large_disk_foundationdb` release image, and `container_foundationdb_version.yml` or `container_rocksdb_version.yml` for the per-version builds. The regexp above accepts release images only; `container_[a-z_]+\.yml@` accepts everything this repository publishes, `dev` included.
-
-The same check as a Kyverno policy, release images only:
-
-```yaml

 As an alternative, a kubernetes Secret can be used (`admin.secret.existingSecret`).
 
-### Admin listen address
-
-Since SeaweedFS 4.46, `weed admin` defaults to listening on loopback (`127.0.0.1`).
-The chart's httpGet readiness/liveness probes dial the pod IP, so the admin
-server must bind a non-loopback address for the probes to succeed. The chart
-therefore passes `-ip={{ .Values.admin.ip }}`, defaulting `admin.ip` to `0.0.0.0`
-(the pre-4.46 behaviour of listening on all interfaces).
-
-Binding a non-loopback address requires authentication: `weed admin` refuses to
-start on a non-loopback address without `-adminPassword`, so the chart fails at
-render time if `admin.ip` is non-loopback and authentication is not configured via
-`admin.secret.adminPassword`, `admin.secret.existingSecret`, or
-`WEED_ADMIN_PASSWORD` supplied through `admin.extraEnvironmentVars` /
-`admin.secretExtraEnvironmentVars`. The whole `127.0.0.0/8` range and `::1` are
-treated as loopback (matching `weed admin`); `localhost` is treated as
-non-loopback. Set `admin.ip` to a loopback address only if you also replace the
-httpGet probes (e.g. with an `exec` probe that checks `127.0.0.1`).
-
-The `-ip` flag requires SeaweedFS 4.46 or newer; pinning `admin.imageOverride`
-to an older image is not supported with this chart version.
-
 ### Admin Data Persistence
 
 The admin component can store configuration and maintenance data. You can configure storage in several ways:

-The patch release matters: 1.91.0 does not build. The edition itself only needs
-1.85; the higher floor comes from the dependency tree — chiefly the AWS SDK — so
-it moves with those crates. CI builds on the latest stable.

-//! Keep glibc from silently converting large short-lived buffers into heap the
-//! process never gives back.
-//!
-//! glibc serves an allocation with `mmap` when it is at least
-//! `M_MMAP_THRESHOLD` (128 KiB by default), and `munmap`s it on free, so the
-//! pages go straight back to the OS. That threshold is **adaptive**: whenever a
-//! block that came from `mmap` is freed, glibc raises the threshold to that
-//! block's size — up to 32 MiB — on the theory that a workload repeatedly
-//! allocating buffers of that size is better served from the heap.
-//!
-//! For a volume server that theory is wrong in a specific, expensive way. EC
-//! reconstruction and needle reassembly allocate large, short-lived buffers.
-//! The first few are mmap'd and freed, which trains the threshold upward; every
-//! later buffer of that size is then carved out of the heap instead. Heap
-//! memory is only returned to the OS from the top of the arena, so those pages
-//! stay resident as anonymous memory for the life of the process. They are
-//! still *reusable* — this is not a leak, and a repeat workload does not grow
-//! the footprint further — but under a hard cgroup `MemoryMax` they are
-//! indistinguishable from a leak, because anonymous pages cannot be reclaimed
-//! under pressure the way page cache can. The retained footprint eats exactly
-//! the headroom that a burst of maintenance work needs, and the process is
-//! OOM-killed while most of its resident memory is free-but-unreturned.
-//!
-//! Measured on a 17-node cluster (EC 10+4, `--index=redb`), one node, two
-//! identical `ec.scrub -mode full` rounds over 10912 EC files each, comparing
-//! the same unit restarted with and without a pinned threshold:
-//!
-//! | | baseline | round 1 | round 2 | 60s idle |
-//! |---|---|---|---|---|
-//! | default (adaptive) | 10 MB | 84 MB | 88 MB | **88 MB** |
-//! | pinned threshold   | 10 MB | 13 MB | 14 MB | **14 MB** |
-//!
-//! 78 MB retained versus 4 MB for identical work. On that cluster's heavier
-//! mixed scrub workloads the same effect reached ~600 MB of retained anonymous
-//! memory per volume server, against a 3 GiB cap.
-//!
-//! Calling `mallopt(M_MMAP_THRESHOLD, ...)` sets the threshold *and* disables
-//! the dynamic adjustment, which is the documented behaviour of setting it
-//! explicitly. We pin it to glibc's own default rather than inventing a value:
-//! the goal is to stop the adaptation, not to second-guess the default.

-The patch release matters: 1.94.0 does not build. The edition itself only needs
-1.85; the higher floor comes from the dependency tree — lance's `aws` feature

 `core` compiles `plugin.proto` with the protoc that protoc-bin-vendored ships,

-/// Decides whether a table is worth sorting.
-///
-/// The question detection actually has to answer is "is this still the data the
-/// sort wrote?", and neither the row count nor the dataset version can answer
-/// it. A rewrite that leaves the row count where it was is invisible to the
-/// first, and the second cannot be recorded at all: the commit carrying the
-/// marker is the commit that creates the version, and a commit that rebases
-/// past a conflict lands on a different number again.
-///
-/// Data file names can answer it. They are chosen before the commit, so the
-/// marker the same commit carries can name them, and they are stable no matter
-/// which version the commit ends up as. So:
-///
-/// - the same files → the table is exactly what the sort left;
-/// - the sorted files still there, with more after them → rows were appended,
-///   and only then is `min_unsorted_rows` consulted, which is the churn that
-///   threshold exists to damp;
-/// - anything else → the data was replaced, whatever the row count says.
-///
-/// Appends only ever add fragments after the existing ones, and lance hands out
-/// fragment ids monotonically even across an overwrite, so "the sorted files
-/// are still there" is a prefix test on the files in fragment order.
-///
-/// Deletes leave the data files alone and write a deletion file beside them, so
-/// they read as unchanged here — which is right: deleting rows does not unsort
-/// the ones that remain.

+# ✅ Correct RDMA Sidecar Approach - Simple Parameter-Based
+
+## 🎯 **You're Right - Simplified Architecture**
+
+The RDMA sidecar should be **simple** and just take the volume server address as a parameter. The volume lookup complexity should stay in `weed mount`, not in the sidecar.
+
+## 🏗️ **Correct Architecture**
+
+### **1. weed mount (Client Side) - Does Volume Lookup**
+```go
+// File: weed/mount/filehandle_read.go (integration point)
+func (fh *FileHandle) tryRDMARead(ctx context.Context, buff []byte, offset int64) (int64, int64, error) {
+    entry := fh.GetEntry()
+    
+    for _, chunk := range entry.GetEntry().Chunks {
+        if offset >= chunk.Offset && offset < chunk.Offset+int64(chunk.Size) {
+            // Parse chunk info
+            volumeID, needleID, cookie, err := ParseFileId(chunk.FileId)
+            if err != nil {
+                return 0, 0, err
+            }
+            
+            // 🔍 VOLUME LOOKUP (in weed mount, not sidecar)
+            volumeServerAddr, err := fh.wfs.lookupVolumeServer(ctx, volumeID)
+            if err != nil {
+                return 0, 0, err
+            }
+            
+            // 🚀 SIMPLE RDMA REQUEST WITH VOLUME SERVER PARAMETER
+            data, isRDMA, err := fh.wfs.rdmaClient.ReadNeedleFromServer(
+                ctx, volumeServerAddr, volumeID, needleID, cookie, chunkOffset, readSize)
+            
+            return int64(copy(buff, data)), time.Now().UnixNano(), nil
+        }
+    }
+}
+```
+
+### **2. RDMA Mount Client - Passes Volume Server Address**
+```go
+// File: weed/mount/rdma_client.go (modify existing)
+func (c *RDMAMountClient) ReadNeedleFromServer(ctx context.Context, volumeServerAddr string, volumeID uint32, needleID uint64, cookie uint32, offset, size uint64) ([]byte, bool, error) {
+    // Simple HTTP request with volume server as parameter
+    reqURL := fmt.Sprintf("http://%s/rdma/read", c.sidecarAddr)
+    
+    requestBody := map[string]interface{}{
+        "volume_server": volumeServerAddr,  // ← KEY: Pass volume server address
+        "volume_id":     volumeID,
+        "needle_id":     needleID,
+        "cookie":        cookie,
+        "offset":        offset,
+        "size":          size,
+    }
+    
+    // POST request with volume server parameter
+    jsonBody, err := json.Marshal(requestBody)
+    if err != nil {
+        return nil, false, fmt.Errorf("failed to marshal request body: %w", err)
+    }
+    resp, err := c.httpClient.Post(reqURL, "application/json", bytes.NewBuffer(jsonBody))
+    if err != nil {
+        return nil, false, fmt.Errorf("http post to sidecar: %w", err)
+    }
+}
+```
+
+### **3. RDMA Sidecar - Simple, No Lookup Logic**
+```go
+// File: seaweedfs-rdma-sidecar/cmd/demo-server/main.go
+func (s *DemoServer) rdmaReadHandler(w http.ResponseWriter, r *http.Request) {
+    if r.Method != http.MethodPost {
+        http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
+        return
+    }
+    
+    // Parse request body
+    var req struct {

+    vid := fmt.Sprintf("%d", volumeID)
+    
+    // Query master server for volume location
+    locations, err := operation.LookupVolumeId(wfs.getMasterFn(), wfs.option.GrpcDialOption, vid)

+    }
+    
+    // Return first available location (or implement smart selection)
+    return locations.Locations[0].Url, nil
+}
+```
+
+## 🎯 **Key Differences from Over-Complicated Approach**
+
+### **❌ Over-Complicated (What I Built Before):**
+- ❌ Sidecar does volume lookup
+- ❌ Sidecar has master client integration  
+- ❌ Sidecar has volume location caching
+- ❌ Sidecar forwards requests to remote sidecars
+- ❌ Complex distributed logic in sidecar
+
+### **✅ Correct Simple Approach:**
+- ✅ **weed mount** does volume lookup (where it belongs)
+- ✅ **weed mount** passes volume server address to sidecar
+- ✅ **Sidecar** is simple and stateless
+- ✅ **Sidecar** just does local RDMA read for given server
+- ✅ **No complex distributed logic in sidecar**
+
+## 🚀 **Request Flow (Corrected)**
+
+1. **User Application** → `read()` system call
+2. **FUSE** → `weed mount` WFS.Read()
+3. **weed mount** → Volume lookup: "Where is volume 7?"
+4. **SeaweedFS Master** → "Volume 7 is on server-B:8080"
+5. **weed mount** → HTTP POST to sidecar: `{volume_server: "server-B:8080", volume: 7, needle: 12345}`
+6. **RDMA Sidecar** → Connect to server-B:8080, do local RDMA read
+7. **RDMA Engine** → Direct memory access to volume file
+8. **Response** → Binary data back to weed mount → user
+
+## 📝 **Implementation Changes Needed**
+
+### **1. Simplify Sidecar (Remove Complex Logic)**
+- Remove `DistributedRDMAClient`
+- Remove volume lookup logic
+- Remove master client integration
+- Keep simple RDMA engine communication
+
+### **2. Add Volume Lookup to weed mount**
+- Add `lookupVolumeServer()` method to WFS
+- Modify `RDMAMountClient` to accept volume server parameter
+- Integrate with existing SeaweedFS volume lookup
+
+### **3. Simple Sidecar API**
+```
+POST /rdma/read
+{
+  "volume_server": "server-B:8080",
+  "volume_id": 7,
+  "needle_id": 12345,
+  "cookie": 0,
+  "offset": 0,
+  "size": 4096
+}
+```
+
+## ✅ **Benefits of Simple Approach**
+
+- **🎯 Single Responsibility**: Sidecar only does RDMA, weed mount does lookup
+- **🔧 Maintainable**: Less complex logic in sidecar
+- **⚡ Performance**: No extra network hops for volume lookup
+- **🏗️ Clean Architecture**: Separation of concerns
+- **🐛 Easier Debugging**: Clear responsibility boundaries
+
+You're absolutely right - this is much cleaner! The sidecar should be a simple RDMA accelerator, not a distributed system coordinator.

+
+## 🚀 Production Deployment
+
+This Docker setup can be adapted for production by:
+
+1. **Replacing Mock RDMA**: Switch to `real-ucx` feature in Rust
+2. **RDMA Hardware**: Add RDMA device mappings and capabilities
+3. **Security**: Remove privileged mode, add proper user/group mapping  
+4. **Scaling**: Use Docker Swarm or Kubernetes for orchestration
+5. **Monitoring**: Add Prometheus metrics and Grafana dashboards
+6. **Persistence**: Configure proper volume management
