admin: stop the maintenance scanner pinning itself to one scan per second after a transient failure (#10887)
* admin: honour persisted task configs when building the maintenance policy
buildPolicyFromTaskConfigs passed a literal nil to vacuum, erasure_coding
and balance LoadConfigFromPersistence. Those functions look for their
LoadXTaskPolicy() accessor via a type assertion, which a nil interface can
never satisfy, so every call fell through to NewDefaultConfig() and the
policy came back with the compiled-in defaults - Enabled: true among them.
A task disabled on disk was therefore still scheduled, and the only trace
was a glog.V(1) "Using default ... configuration" line.
Thread the real ConfigPersistence through instead. There are two copies of
this function: the one in weed/admin/dash builds config.Policy on the
normal admin startup path and can simply take cp as its receiver, and the
one in weed/admin/maintenance is the fallback used when the config carries
no policy yet, which now receives the store from NewMaintenanceManager.
weed/admin/dash already imports weed/admin/maintenance, so the maintenance
side has to keep the duck-typed interface{} parameter that the task
loaders already use rather than importing the concrete type back.
The store is only handed over when a data directory is configured: an
unconfigured one has nothing to read, and a typed nil pointer would pass
the loaders' type assertion and then panic on first use.
Fixes #10874
* admin: restore the maintenance scan cadence after an error backoff
scanLoop shortens its ticker to the error backoff delay after a failed
scan, but it decided whether to replace the ticker by comparing the
target interval against the configured scan interval instead of against
the interval the ticker was actually running at. Once the errors stopped,
getScanInterval returned the configured interval again, the comparison
came out false, and the ticker was left at the backoff delay - so a
single transient scan failure pinned the scanner to one scan per second
for the rest of the process lifetime. That is the ~1/second cadence in
issue #10874: 658 KB/s of "Cancelled N stale pending balance tasks
before re-detection" and 193k orphaned task files over two days.
Track the interval the ticker is running at and compare against that, so
both entering the backoff and returning to the normal cadence replace the
ticker.
While in here:
- defer ticker.Stop() bound the ticker that was current when the defer
was registered, so every replacement ticker leaked on return. Wrap it
in a closure.
- running was written by Start/Stop and read by all three background
loops without synchronisation. Guard it with the existing mutex, fold
the running check in triggerScanInternal into the lock it already
takes, and make Stop a no-op when not running so a second call cannot
close the stop channel twice.

* admin: make the maintenance policy actually reach the task detectors
Loading the persisted task configs into the maintenance policy only
matters if something reads that policy, and nothing did.
MaintenanceIntegration pushes the policy into every registered detector
and scheduler through interface{ SetEnabled(bool) } and
interface{ SetMaxConcurrent(int) } type assertions. Every task registered
through base.RegisterTask is backed by base.GenericDetector and
base.GenericScheduler, and neither implemented either method, so all four
assertions failed silently for every task on every startup. The policy's
enabled flag reached nothing: ScanWithTaskDetectors gates on
detector.IsEnabled(), and the queue's policy lookups for max concurrent
and repeat interval are fallbacks that only fire when the scheduler
reports zero, which the generic scheduler never does.
Add the setters, delegating to the TaskConfig.SetEnabled the interface
already declares and to TaskDefinition.MaxConcurrent, which is what
GetMaxConcurrent returns.
Applying the policy required three more fixes, because with the
assertions working the policy could now do damage as well as good:
- IsTaskEnabled reports false for a task type the policy has no entry
for, so applying it unconditionally would have disabled every task the
policy does not list. Skip task types with no policy entry: no entry
means no opinion, not disabled.
- ec_balance was exactly such a task. It is registered like the other
three but had no entry in the policy builder and no accessor on
ConfigPersistence at all, so its configuration could never be
persisted. Add SaveEcBalanceTaskPolicy/LoadEcBalanceTaskPolicy, the
task_ec_balance.pb file, the SaveTaskPolicy dispatcher case, and the
policy entry.
- InitMaintenanceManager ran before loadTaskConfigurationsFromPersistence,
which replaces each task's whole config object, so the policy was
applied and then immediately thrown away. Swap the order. Both read the
same files, so the policy is now the last writer and stays
authoritative.
MaintenanceManager.UpdateConfig also updated the queue's and the
scanner's policy but not the integration's, so a policy changed at
runtime never reached the detectors. Add MaintenanceIntegration.SetPolicy
and call it.
While building the policy, stop hand-copying each task's fields and use
the task's own ToTaskPolicy(). The hand-written version was a second
definition of every task's policy and had already lost the erasure coding
preferred tags and replica placement and the balance IO rate limit. For
the same reason, the "nothing persisted yet" branches of
LoadVacuumTaskPolicy, LoadErasureCodingTaskPolicy and
LoadBalanceTaskPolicy now derive from each task's NewDefaultConfig()
instead of a third hand-written copy. Those copies had drifted, so with a
data directory but no config file on disk the effective defaults differed
from what the task and the admin UI schema both advertise:
vacuum scan interval 24h -> 2h
balance scan interval 6h -> 30m
balance imbalance 0.1 -> 0.2
erasure coding scan interval 168h -> 1h
erasure coding fullness 0.90 -> 0.95
erasure coding min volume 1024MB -> 30MB
Finally, weed/admin/dash and weed/admin/maintenance each carried a copy
of the policy builder and they had already diverged. Export the
maintenance one as BuildPolicyFromTaskConfigs and have dash call it.

* worker: warn when a config store cannot supply a task's persisted config
LoadConfigFromPersistence logged a single glog.V(1) "Using default X
configuration" for every way of not loading anything, so the bug in
issue #10874 - a store handed in that the type assertion rejects, leaving
a task running on compiled-in defaults - looked exactly like the normal
"no data directory configured" case. The reporter had to read the source
to work out why their disabled task kept running, and asked for this
specifically.
Separate the cases. A non-nil store that does not provide the accessor is
always a wiring bug and is now logged at warning level, naming the type
and the missing method. A read error or a policy that will not apply is
also a warning. No persistence configured, and a store with nothing saved
yet, stay at V(1): those are normal.
Refs #10874
* admin: stop GetTaskPolicy panicking on a maintenance policy that is nil
GetTaskPolicy dereferenced its MaintenancePolicy argument to look at
TaskPolicies, so IsTaskEnabled, GetMaxConcurrent and GetRepeatInterval
all took the admin process down when handed a nil policy. A nil policy is
not a programming error here: MaintenanceConfig.Policy is unset until
something builds one, DefaultMaintenanceConfig returns a config with no
policy at all, and UpdateConfig installs whatever config it is given.
Found by calling IsTaskEnabled with the policy from a freshly defaulted
MaintenanceConfig.
Treat a nil policy as "no entry": no task enabled, the safe concurrency
default of 1, and a repeat interval of 0 so callers fall back to their
own default instead of reading DefaultRepeatIntervalSeconds off nil.
Also add the startup test this was found with. It walks the admin
server's startup sequence over a data directory that has balance saved as
disabled and checks the state that decides whether issue #10874 happens:
the balance detector reports disabled, vacuum stays enabled, and tasks
whose config was never saved keep their compiled-in default.
Refs #10874
* admin: document the synchronisation SetPolicy would need beyond startup
ConfigureTasksFromPolicy now really writes TaskDefinition.Config and
TaskDefinition.MaxConcurrent, which the scan loop reads through
detector.IsEnabled() with nothing synchronising the two. Every caller
runs during admin server startup today, before the scan loop exists, so
there is no live race - but the next caller has to add the locking, and
the same already applies to UpdateAllConfigs replacing the whole config
object. Write it down at the seam instead of leaving it to be
rediscovered.

admin/maintenance: reload in-flight tasks on startup instead of discarding them (#9857)
* admin/maintenance: reload in-flight tasks on startup instead of discarding LoadTasksFromPersistence deleted all persisted task files on startup and relied on the scanner to re-detect, so saved task state was never consumed — the persistence was effectively write-only. Reload non-terminal tasks (pending/assigned/in_progress) into the queue, resetting in-flight ones to pending since their worker is gone after a restart (maintenance tasks are idempotent). Terminal task files are dropped; the scanner still backfills anything not persisted. * address review: nil-guard reloaded tasks and SyncTask to ActiveTopology - skip nil entries from LoadAllTaskStates (corrupted state) - re-sync restored tasks with MaintenanceIntegration so ActiveTopology (in-memory, empty on startup) knows about them; otherwise GetNextTask's AssignTask rejects them as unknown and they never get assigned |

fix(admin): reduce memory usage and verbose logging for large clusters (#8927)
* fix(admin): reduce memory usage and verbose logging for large clusters (#8919) The admin server used excessive memory and produced thousands of log lines on clusters with many volumes (e.g., 33k volumes). Three root causes: 1. Scanner duplicated all volume metrics: getVolumeHealthMetrics() created VolumeHealthMetrics objects, then convertToTaskMetrics() copied them all into identical types.VolumeHealthMetrics. Now uses the task-system type directly, eliminating the duplicate allocation and removing convertToTaskMetrics. 2. All previous task states loaded at startup: LoadTasksFromPersistence read and deserialized every .pb file from disk, logging each one. With thousands of balance tasks persisted, this caused massive startup I/O, memory usage, and log noise (including unguarded DEBUG glog.Infof per task). Now starts with an empty queue — the scanner re-detects current needs from live cluster state. Terminal tasks are purged from memory and disk when new scan results arrive. 3. Verbose per-volume/per-node logging: V(2) and V(3) logs produced thousands of lines per scan. Per-volume logs bumped to V(4), per-node/rack/disk logs bumped to V(3). Topology summary now logs counts instead of full node ID arrays. Also removes lastTopologyInfo field from MaintenanceScanner — the raw protobuf topology is returned as a local value and not retained between 30-minute scans. * fix(admin): delete stale task files at startup, add DeleteAllTaskStates Old task .pb files from previous runs were left on disk. The periodic CleanupCompletedTasks still loads all files to find completed ones — the same expensive 4GB path from the pprof profile. Now at startup, DeleteAllTaskStates removes all .pb files by scanning the directory without reading or deserializing them. The scanner will re-detect any tasks still needed from live cluster state. * fix(admin): don't persist terminal tasks to disk CompleteTask was saving failed/completed tasks to disk where they'd accumulate. The periodic cleanup only triggered for completed tasks, not failed ones. Now terminal tasks are deleted from disk immediately and only kept in memory for the current session's UI. * fix(admin): cap in-memory tasks to 100 per job type Without a limit, the task map grows unbounded — balance could create thousands of pending tasks for a cluster with many imbalanced volumes. Now AddTask rejects new tasks when a job type already has 100 in the queue. The scanner will re-detect skipped volumes on the next scan. * fix(admin): address PR review - memory-only purge, active-only capacity - purgeTerminalTasks now only cleans in-memory map (terminal tasks are already deleted from disk by CompleteTask) - Per-type capacity limit counts only active tasks (pending/assigned/ in_progress), not terminal ones - When at capacity, purge terminal tasks first before rejecting * fix(admin): fix orphaned comment, add TaskStatusCancelled to terminal switch - Move hasQueuedOrActiveTaskForVolume comment to its function definition - Add TaskStatusCancelled to the terminal state switch in CompleteTask so cancelled task files are deleted from disk |
