* feat: add collection pattern to delete empty volumes
Co-authored-by: Codex <noreply@openai.com>
* shell: match collection pattern with wildcard matcher
Use wildcard.MatchesWildcard in the shared collection-pattern helper,
matching command_volume_fix_replication's matchCollectionPattern. The
flag only advertises '*' and '?', which is exactly what the matcher
supports.

* shell: warn in volume.list when a volume id spans collections
A reused volume id, the result of the master handing out an id already
used by another collection (for example after losing its max-volume-id
counter on restart), makes collection.delete destroy the wrong
collection's data and makes any bare-id lookup, move, or vacuum
ambiguous. volume.list now scans the full topology and warns on ids
present in more than one collection so the clash is visible before any
destructive operation.
* volume.list: track duplicate ids lazily, sort with slices.Sort
Allocate the per-id collection set only on the first cross-collection clash
instead of one set per volume, so allocations scale with duplicates rather
than the volume count.
* fix(volume.list): show one entry per physical disk on multi-disk nodes
DataNodeInfo.DiskInfos is keyed by disk type, so several same-type
physical disks on one node collapse to a single map entry at the master.
volume.list iterated that map directly and reported one "Disk hdd ...
id:0" line per node, hiding the per-disk volume and shard layout. EC
operators on multi-disk volume servers had no way to verify which
physical disk a shard landed on.
Lift the per-physical-disk split into a DiskInfo.SplitByPhysicalDisk()
method on the proto type so consumers outside admin/topology can use
it. Apply it in writeDataNodeInfo so the verbose Disk block shows one
entry per physical disk, ordered by DiskId. Capacity counters are
split evenly across reconstructed disks since the wire format doesn't
carry per-disk capacity yet.
This is a display-only change. ActiveTopology already did the split on
its own and is now updated to call the shared helper.
* fix(volume.list): preserve totals, count active/remote exactly, dedupe header
Address review feedback on the per-physical-disk split:
- share() truncated remainders so reconstructed per-disk counters could
sum to less than the original aggregate (10 / 3 = 3+3+3). Distribute
the remainder to the lowest disk ids so MaxVolumeCount and
FreeVolumeCount sum exactly back to the node totals.
- ActiveVolumeCount and RemoteVolumeCount are derivable per disk from
the VolumeInfos already grouped by DiskId, so count them exactly
(ReadOnly=false and RemoteStorageName!="" respectively) instead of
approximating with an even split.
- writeDataNodeInfo's per-disk callback fired the DataNode header on
every iteration after the split, so a node with 6 physical disks
emitted 6 DataNode headers. Guard the callback with headerPrinted so
the header still appears at most once per node.
- Sort split disks deterministically using explicit DiskId comparison
to avoid int overflow risk on 32-bit systems.
- Tighten the volume.list test substring to "id:N\n" so unrelated
tokens like "ec volume id:101" don't accidentally match the id:1
needle, and assert the rack callback fires once.
* Fix#8040: Support 'default' keyword in collectionPattern to match default collection
The default collection in SeaweedFS is represented as an empty string internally.
Previously, it was impossible to specifically target only the default collection
because:
- Empty collectionPattern matched ALL collections (filter was skipped)
- Using collectionPattern="default" tried to match the literal string "default"
This commit adds special handling for the keyword "default" in collectionPattern
across multiple shell commands:
- volume.tier.move
- volume.list
- volume.fix.replication
- volume.configure.replication
Now users can use -collectionPattern="default" to specifically target volumes
in the default collection (empty collection name), while maintaining backward
compatibility where empty pattern matches all collections.
Updated help text to document this feature.
* Update compileCollectionPattern to support 'default' keyword
This extends the fix to all commands that use regex-based collection
pattern matching:
- ec.encode
- ec.decode
- volume.tier.download
- volume.balance
The compileCollectionPattern function now treats "default" as a special
keyword that compiles to the regex "^$" (matching empty strings), making
it consistent with the other commands that use filepath.Match.
* Use CollectionDefault constant instead of hardcoded "default" string
Refactored the collection pattern matching logic to use a central constant
CollectionDefault defined in weed/shell/common.go. This improves maintainability
and ensures consistency across all shell commands.
* Address PR review feedback: simplify logic and use '_default' keyword
Changes:
1. Changed CollectionDefault from "default" to "_default" to avoid collision
with literal collection names
2. Simplified pattern matching logic to reduce code duplication across all
affected commands
3. Fixed error handling in command_volume_tier_move.go to properly propagate
filepath.Match errors instead of swallowing them
4. Updated documentation to clarify how to match a literal "default"
collection using regex patterns like "^default$"
This addresses all feedback from PR review comments.
* Remove unnecessary documentation about matching literal 'default'
Since we changed the keyword to '_default', users can now simply use
'default' to match a literal collection named "default". The previous
documentation about using regex patterns was confusing and no longer needed.
* Fix error propagation and empty pattern handling
1. command_volume_tier_move.go: Added early termination check after
eachDataNode callback to stop processing remaining nodes if a pattern
matching error occurred, improving efficiency
2. command_volume_configure_replication.go: Fixed empty pattern handling
to match all collections (collectionMatched = true when pattern is empty),
mirroring the behavior in other commands
These changes address the remaining PR review feedback.
SeaweedFS tracks EC shard sizes on topology data stuctures, but this information is never
relayed to master servers :( The end result is that commands reporting disk usage, such
as `volume.list` and `cluster.status`, yield incorrect figures when EC shards are present.
As an example for a simple 5-node test cluster, before...
