* shell: add volume.balance -byDiskUsage to balance by actual data
The default balancer ranks servers by slot density, dividing used volumes by
MaxVolumeCount. When MaxVolumeCount is configured higher than the disk can hold,
a physically near-full server looks nearly empty and gets picked as the move
target, so balancing drains less-full servers onto an already-full one.
-byDiskUsage ranks servers by the actual data they hold (sum of volume sizes)
instead, so the fullest-by-data server is treated as full and balancing drains
it. It assumes comparable disk sizes per disk type and still respects each
server's free volume slots. Default behavior is unchanged.
* plumb physical disk usage into topology, gate volume.balance on it
Volume servers now report each disk's filesystem total/free bytes in the
heartbeat, and the master stores them in DiskInfo. volume.balance uses them to
skip any move target whose disk is already near full (-maxDiskUsagePercent,
default 90), so an over-configured maxVolumeCount can no longer make a
physically full server look empty and get drained onto. The gate judges each
server against its own disk, so heterogeneous disk sizes are fine; servers that
do not report bytes fall back to slot-only behavior.
Rust seaweed-volume mirrors the heartbeat reporting.
* admin: report real physical disk capacity when volume servers provide it
The dashboard estimated server capacity as maxVolumeCount * volumeSizeLimit,
which overstates it when maxVolumeCount is set higher than the disk holds.
Prefer the filesystem capacity now reported per disk, falling back to the
estimate for servers that do not report it.
* worker: gate automatic balance on physical disk fullness too
The maintenance balance worker selects the least slot-utilized server as the
move destination, so an over-configured maxVolumeCount makes a physically full
server look empty and get drained onto — the same defect as the shell command.
Now that DiskInfo carries real disk bytes, skip any destination whose disk is
at/above 90% used (per server, against its own disk); a full server can still be
a source. When every candidate destination is full, create no tasks. Servers
that do not report disk bytes are not gated.
* balance: share the physical-disk-fullness gate between shell and worker
The shell volume.balance command and the maintenance balance worker each grew
their own copy of the disk-fullness gate (targetDiskTooFull / destinationDiskTooFull)
and a maxDiskUsagePercent=90 constant. Pull both into weed/topology/balancer
(DiskTooFullAfter + DefaultMaxDiskUsagePercent) so the policy has one home and the
two balancers can't drift.
* balance: harden the physical-disk gate
Guard against a nil DiskInfo in the byte/slot lookups. Let a zero disk-capacity
report clear previously stored bytes (0 means "not reported" for bytes, unlike
maxVolumeCount), so a server that stops reporting falls back to slot-only instead
of trusting stale capacity. In the worker, charge each planned move's bytes to
its destination within a detection cycle so the gate sees a target fill up rather
than only its heartbeat-time free space. Note the per-location capacity summing
assumes one location per filesystem (the used ratio the gate relies on stays
correct regardless; absolute capacity can over-report).
* fix(topology): keep physical disk 0 distinct in SplitByPhysicalDisk
DiskId 0 doubles as the first physical disk (Locations[0]) and the
protobuf "unset" default. SplitByPhysicalDisk folded every DiskId-0
record onto the aggregate DiskId whenever that was non-zero, so on a
multi-disk node the first disk's volumes merged into whichever disk
held volumes[0]: the node reported one fewer disk, the sibling showed
~2x volumes, and per-disk max was smeared across the survivors. This
surfaced as cluster.status and volume.list undercounting disks.
Only treat 0 as unset when no record carries a non-zero DiskId; with a
mix, 0 is a real disk and keeps its own entry.
* fix(admin): resolve physical disk 0 in active-topology indexes
rebuildIndexes re-derived each volume/EC record's physical disk id with
the same "DiskId 0 means unset" heuristic SplitByPhysicalDisk used, so
the two agreed only by sharing the bug. Now that SplitByPhysicalDisk
keeps disk 0 distinct, the duplicated heuristic would fold disk-0 records
onto a sibling while at.disks kept them on disk 0; GetVolumeLocations and
GetECShardLocations then matched no record and silently dropped every
volume and EC shard on the first disk, starving balance and EC tasks.
Build the indexes from the same SplitByPhysicalDisk reconstruction that
builds at.disks, so the keys always resolve. One source of truth instead
of a parallel normalize.
* fix(ec): allow physical disk 0 as preferred EC shard target
pickBestDiskOnNode gated its result on bestDiskId != 0, but 0 is both a
valid physical disk and the uint32 zero value, so a best-scoring disk 0
was discarded and the non-matching fallback returned instead. Gate on
bestScore.
* test(admin): cover EC-shard index resolution for physical disk 0
rebuildIndexes builds ecShardIndex the same way as volumeIndex; pin the EC
path too so a shard on disk 0 keeps resolving via GetECShardLocations.
* proto: per-disk type/capacity in DiskTag, DiskInfo.physical_disks
DiskTag gains type + max_volume_count so the heartbeat can describe every
physical disk, including ones holding no volumes or EC shards. DiskInfo
gains physical_disks so the master can hand the full per-type disk set to
per-physical-disk consumers.
* feat(volume): report each physical disk's type and capacity
CollectHeartbeat fills DiskTag.type and the per-disk effective max for
every location, so the master can account for disks that hold no volumes
or EC shards yet. Rust heartbeat mirrors it.
* feat(master): surface empty disks in the per-physical-disk view
The master records each disk's type and max from DiskTags and lists them
on DiskInfo.physical_disks per type, including disks with no volumes or
EC shards. SplitByPhysicalDisk enumerates that full set and gives each
disk its exact max, so cluster.status, volume.list and the admin
topology count and can target empty disks. Without physical_disks the
even-split fallback is unchanged.
* fix(master): clamp per-disk free at zero for over-allocated disks
In the exact-max path FreeVolumeCount could go negative when a disk holds
more volumes than its max; a negative would reduce the node's summed free
and block placement on healthy disks. Clamp at 0.
* fix(master): rebuild disk tags fresh each heartbeat
DiskTags is the full authoritative per-disk list every heartbeat, so
rebuild dn.diskTags from scratch like dn.diskBackends; merging left stale
entries for removed disks.
* fix(master): keep zero-capacity disks in physical_disks
A disk reporting max 0 (an unavailable disk) is a valid physical disk,
not a signal to drop it. List every disk of the type, but only emit
physical_disks when the node reports real per-disk capacity, so an older
server sending all zeros still falls back to the aggregate split.
* test(volume): cover disk-space-low per-disk max in heartbeat
Assert DiskTag.max_volume_count follows the used-slots override when a
location is low on space, matching the per-type max_volume_counts.
* chore: trim comments on the empty-disk change
Drop narration; keep only the non-obvious why (disk-0 sentinel, exact-max
free clamp, EC slots not subtracted, all-zeros fallback).
* refactor(master): merge per-disk tags and capacity into one map
diskTags and diskBackends were parallel maps keyed by the same DiskId and
filled together from DiskTags. Fold them into one diskMetas map of
{tags, type, max}.
* refactor(proto): per-disk max as a map keyed by disk id
physical_disks was a repeated {disk_id, max_volume_count} whose fields
duplicated DiskInfo's own disk_id/max_volume_count. A map<uint32,int64>
keyed by disk id expresses "max per disk" directly, drops the extra
PhysicalDiskInfo message, and the consumer reads it as the disk set.
* docs(proto): note DiskInfo.disk_id's two meanings
Identity on a per-physical-disk DiskInfo (from SplitByPhysicalDisk),
representative fallback on the type-keyed aggregate.
* Add volume dir tags to topology

* Add EC placement planner tag tests
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Refactor EC placement tests to reuse buildActiveTopology
Remove buildActiveTopologyWithDiskTags helper function and consolidate
tag setup inline in test cases. Tests now use UpdateTopology to apply
tags after topology creation, reusing the existing buildActiveTopology
function rather than duplicating its logic.
All tag scenario tests pass:
- TestECPlacementPlannerPrefersTaggedDisks
- TestECPlacementPlannerFallsBackWhenTagsInsufficient

* Consolidate normalizeTagList into shared util package
Extract normalizeTagList from three locations (volume.go,
detection.go, erasure_coding_handler.go) into new weed/util/tag.go
as exported NormalizeTagList function. Replace all duplicate
implementations with imports and calls to util.NormalizeTagList.
This improves code reuse and maintainability by centralizing
tag normalization logic.

* Add PreferredTags to EC config persistence
Add preferred_tags field to ErasureCodingTaskConfig protobuf with field
number 5. Update GetConfigSpec to include preferred_tags field in the
UI configuration schema. Add PreferredTags to ToTaskPolicy to serialize
config to protobuf. Add PreferredTags to FromTaskPolicy to deserialize
from protobuf with defensive copy to prevent external mutation.
This allows EC preferred tags to be persisted and restored across
worker restarts.

* Add defensive copy for Tags slice in DiskLocation
Copy the incoming tags slice in NewDiskLocation instead of storing
by reference. This prevents external callers from mutating the
DiskLocation.Tags slice after construction, improving encapsulation
and preventing unexpected changes to disk metadata.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Add doc comment to buildCandidateSets method
Document the tiered candidate selection and fallback behavior. Explain
that for a planner with preferredTags, it accumulates disks matching
each tag in order into progressively larger tiers, emits a candidate
set once a tier reaches shardsNeeded, and finally falls back to the
full candidates set if preferred-tag tiers are insufficient.
This clarifies the intended semantics for future maintainers.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Apply final PR review fixes
1. Update parseVolumeTags to replicate single tag entry to all folders
instead of leaving some folders with nil tags. This prevents nil
pointer dereferences when processing folders without explicit tags.
2. Add defensive copy in ToTaskPolicy for PreferredTags slice to match
the pattern used in FromTaskPolicy, preventing external mutation of
the returned TaskPolicy.
3. Add clarifying comment in buildCandidateSets explaining that the
shardsNeeded <= 0 branch is a defensive check for direct callers,
since selectDestinations guarantees shardsNeeded > 0.

* Fix nil pointer dereference in parseVolumeTags
Ensure all folder tags are initialized to either normalized tags or
empty slices, not nil. When multiple tag entries are provided and there
are more folders than entries, remaining folders now get empty slices
instead of nil, preventing nil pointer dereference in downstream code.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Fix NormalizeTagList to return empty slice instead of nil
Change NormalizeTagList to always return a non-nil slice. When all tags
are empty or whitespace after normalization, return an empty slice
instead of nil. This prevents nil pointer dereferences in downstream
code that expects a valid (possibly empty) slice.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Add nil safety check for v.tags pointer
Add a safety check to handle the case where v.tags might be nil,
preventing a nil pointer dereference. If v.tags is nil, use an empty
string instead. This is defensive programming to prevent panics in
edge cases.

* Add volume.tags flag to weed server and weed mini commands
Add the volume.tags CLI option to both the 'weed server' and 'weed mini'
commands. This allows users to specify disk tags when running the
combined server modes, just like they can with 'weed volume'.
The flag uses the same format and description as the volume command:
comma-separated tag groups per data dir with ':' separators
(e.g. fast:ssd,archive).

* pb: add id field to Heartbeat message for stable volume server identification
This adds an 'id' field to the Heartbeat protobuf message that allows
volume servers to identify themselves independently of their IP:port address.
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* storage: add Id field to Store struct
Add Id field to Store struct and include it in CollectHeartbeat().
The Id field provides a stable volume server identity independent of IP:port.
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* topology: support id-based DataNode identification
Update GetOrCreateDataNode to accept an id parameter for stable node
identification. When id is provided, the DataNode can maintain its identity
even when its IP address changes (e.g., in Kubernetes pod reschedules).
For backward compatibility:
- If id is provided, use it as the node ID
- If id is empty, fall back to ip:port
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* volume: add -id flag for stable volume server identity
Add -id command line flag to volume server that allows specifying a stable
identifier independent of the IP address. This is useful for Kubernetes
deployments with hostPath volumes where pods can be rescheduled to different
nodes while the persisted data remains on the original node.
Usage: weed volume -id=node-1 -ip=10.0.0.1 ...
If -id is not specified, it defaults to ip:port for backward compatibility.
Fixes https://github.com/seaweedfs/seaweedfs/issues/7487
* server: add -volume.id flag to weed server command
Support the -volume.id flag in the all-in-one 'weed server' command,
consistent with the standalone 'weed volume' command.
Usage: weed server -volume.id=node-1 ...
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* topology: add test for id-based DataNode identification
Test the key scenarios:
1. Create DataNode with explicit id
2. Same id with different IP returns same DataNode (K8s reschedule)
3. IP/PublicUrl are updated when node reconnects with new address
4. Different id creates new DataNode
5. Empty id falls back to ip:port (backward compatibility)
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* pb: add address field to DataNodeInfo for proper node addressing
Previously, DataNodeInfo.Id was used as the node address, which worked
when Id was always ip:port. Now that Id can be an explicit string,
we need a separate Address field for connection purposes.
Changes:
- Add 'address' field to DataNodeInfo protobuf message
- Update ToDataNodeInfo() to populate the address field
- Update NewServerAddressFromDataNode() to use Address (with Id fallback)
- Fix LookupEcVolume to use dn.Url() instead of dn.Id()
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* fix: trim whitespace from volume server id and fix test
- Trim whitespace from -id flag to treat ' ' as empty
- Fix store_load_balancing_test.go to include id parameter in NewStore call
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* refactor: extract GetVolumeServerId to util package
Move the volume server ID determination logic to a shared utility function
to avoid code duplication between volume.go and rack.go.
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* fix: improve transition logic for legacy nodes
- Use exact ip:port match instead of net.SplitHostPort heuristic
- Update GrpcPort and PublicUrl during transition for consistency
- Remove unused net import
Ref: https://github.com/seaweedfs/seaweedfs/issues/7487
* fix: add id normalization and address change logging
- Normalize id parameter at function boundary (trim whitespace)
- Log when DataNode IP:Port changes (helps debug K8s pod rescheduling)
