* volume.tier.move: fulfill target replication before deleting old replicas
When -toReplication is specified, volume.tier.move now creates all
required replicas on the destination tier before deleting old replicas.
This closes the data-loss window where only one copy existed on the
target tier while awaiting volume.fix.replication.
If replication fulfillment fails, old replicas are preserved and marked
writable so the volume remains accessible.
Also extracts replicateVolumeToServer and configureVolumeReplication
helpers to reduce duplication across volume.tier.move and
volume.fix.replication.
Fixes#8937
* volume.tier.move: always fulfill replication before deleting old replicas
When -toReplication is specified, use that replication setting.
Otherwise, read the volume's existing replication from the super block.
In both cases, all required replicas are created on the destination
tier before old replicas are deleted.
If replication fulfillment fails (e.g. not enough destination nodes),
old replicas are preserved and marked writable so no data is lost.
* volume.tier.move: address review feedback on ensureReplicationFulfilled
- Add 5s delay before re-collecting topology to allow master heartbeat
propagation after the move
- Add nil guard for targetTierReplicas to prevent panic if the moved
replica is not yet visible in the topology
- Treat configureVolumeReplication failure as a hard error instead of a
warning, so the rollback logic preserves old replicas
* volume.tier.move: harden replication config error handling
- Make configureVolumeReplication failure on the primary moved replica a
hard error that aborts the move, instead of logging and continuing
- Configure replication metadata on all existing target-tier replicas
(not just newly created ones) when -toReplication is specified
- Deletion of old replicas cannot affect new replicas since the
locations list only contains pre-move servers (verified, no change)
* volume.tier.move: fix cleanup deleting fulfilled replicas and broken recovery
Fix 1: The cleanup loop now preserves pre-existing target-tier replicas
that ensureReplicationFulfilled counted toward the replication target.
Previously, a mixed-tier volume with an existing replica on the target
tier could have that replica deleted right after being counted as
fulfilled, leaving the volume under-replicated.
ensureReplicationFulfilled now returns a preserveServers set that the
deletion loop checks before removing any old replica.
Fix 2: Failure paths after LiveMoveVolume (which deletes the source
replica) now use restoreSurvivingReplicasWritable instead of
markVolumeReplicasWritable. The old helper stopped on first error, so
attempting to mark the already-deleted source writable would prevent
all surviving replicas from being restored. The new helper skips the
deleted source and continues through all remaining locations, logging
per-replica errors instead of aborting.
* volume.tier.move: mark preserved replicas writable, skip nodes with existing volume
Fix 1: Preserved pre-existing target-tier replicas were left read-only
after the move completed. They were marked read-only at the start
(along with all other replicas) but never restored since the old code
deleted them. Now they are explicitly marked writable before cleanup.
Fix 2: The fulfillment loop could pick a candidate node that already
hosts this volume on a different disk type, causing a VolumeCopy
conflict. Added a guard that skips any node already hosting the volume
(on any disk) before attempting replication.
* 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.
* fix: sync replica entries before ec.encode and volume.tier.move (#7797)
This addresses the data inconsistency risk in multi-replica volumes.
When ec.encode or volume.tier.move operates on a multi-replica volume:
1. Find the replica with the highest file count (the 'best' one)
2. Copy missing entries from other replicas INTO this best replica
3. Use this union replica for the destructive operation
This ensures no data is lost due to replica inconsistency before
EC encoding or tier moving.
Added:
- command_volume_replica_check.go: Core sync and select logic
- command_volume_replica_check_test.go: Test coverage
Modified:
- command_ec_encode.go: Call syncAndSelectBestReplica before encoding
- command_volume_tier_move.go: Call syncAndSelectBestReplica before moving
Fixes#7797
* test: add integration test for replicated volume sync during ec.encode
* test: improve retry logic for replicated volume integration test
* fix: resolve JWT issue in integration tests by using empty security.toml
* address review comments: add readNeedleMeta, parallelize status fetch, fix collection param, fix test issues
* test: use collection parameter consistently in replica sync test
* fix: convert weed binary path to absolute to work with changed working directory
* fix: remove skip behavior, keep tests failing on missing binary
* fix: always check recency for each needle, add divergent replica test
* Unify the parameter to disable dry-run on weed shell commands to --apply (instead of --force).
* lint
* refactor
* Execution Order Corrected
* handle deprecated force flag
* fix help messages
* Refactoring]: Using flag.FlagSet.Visit()
* consistent with other commands
* Checks for both flags
* fix toml files
