Chris LuandGitHub 9a7cfaf371 admin: stop holding the shell admin lock across whole scheduler batches (#10290)
* admin: let waiting shell clients win the admin lock

The admin lock manager re-acquired the cluster shell lock immediately
after releasing it, while a waiting weed shell client only polls the
master once a second, so an operator could lose the race indefinitely.
Leave the lock free for slightly more than one poll interval before
re-acquiring, and once overlapping reference-counted holds have kept
the lock continuously held for over a minute, make new admin-side
acquires wait for a full release before piggybacking.

* admin/plugin: take the shell lock per detection and per job, not per batch

The default-lane scheduler acquired the cluster shell lock once and
held it across the whole pass: every due job type's detection plus all
of its dispatched jobs, each drained to completion. A manual weed
shell operation sharing that lock could stall behind the batch for up
to the extended execution window.

Hold the lock only while it protects something: around each detection
scan and around each dispatched job. Manual shell operations now wait
for at most one in-flight job. The admin UI detect+execute path stops
wrapping dispatch in an outer hold, since a nested acquire would
deadlock against the lock manager's fairness window; detection and
per-job dispatch take the lock themselves.

* admin/plugin: stop extending the dispatch window to the largest job estimate

When any proposal's estimated runtime exceeded the remaining
JobTypeMaxRuntime, the whole dispatch context was replaced with a
fresh one capped at eight hours, so a single balance backlog could
hold the default lane (and with it erasure_coding and vacuum
detection) for that long.

Keep the dispatch window at JobTypeMaxRuntime and instead detach each
started attempt onto its own estimated-runtime deadline. Large jobs
still get their full time once started; jobs not yet started when the
window closes are canceled and re-proposed by a later detection, so
sibling job types get a turn every window.

* worker/balance: re-check each planned move against the master before executing

A balance plan is computed at detection time, but the admin lock is
released between detection and execution, so a manual shell operation
can rearrange the volume in the gap. The task's own guards catch a
vanished source, but a target that gained a replica in the meantime
would be silently overwritten by VolumeCopy and the source delete
would then reduce the volume to a single copy.

Before executing each move, ask the master for the volume's current
locations (uncached) and skip the move if the volume has left the
source or the target already holds a replica. Skipped moves fail with
a stale-move error and the next detection replans them. Without master
addresses in the cluster context the check is skipped, preserving the
old behavior with older admins.

* admin: block re-acquire while the final lock release is in flight

Release dropped the manager mutex before calling ReleaseLock, so a
concurrent Acquire could see hold count zero and call RequestLock
while the locker still considered itself locked. That request no-ops,
leaving a hold with no live master lease. Track the in-flight release
and make Acquire wait for it.

Also normalize a nil release function from lock manager
implementations, and make the yield and fairness windows per-instance
fields so tests stop mutating globals.

Chris LuandGitHub 5d43f84df7 refactor(plugin): rename detection_interval_seconds → detection_interval_minutes (#9366)
Minutes is the natural granularity for detection cadence — every
production handler already set the seconds field to a 60-multiple
(17*60, 30*60, 3600, 24*60*60). Switching to minutes drops the *60
arithmetic and matches the unit conventions used elsewhere in the
plugin worker forms.

- Proto: AdminRuntimeDefaults + AdminRuntimeConfig.detection_interval_*
  field renamed.
- Helpers: durationFromMinutes / minutesFromDuration alongside the
  existing seconds variants in plugin_scheduler.go.
- Handlers: vacuum, ec_balance, balance, erasure_coding, iceberg,
  admin_script, s3_lifecycle now declare DetectionIntervalMinutes.
- Admin: scheduler_status + types + UI templ + plugin_api.go pass
  through the new field; UI label and table cells switch to "min".

Chris LuandGitHub a95b8396e4 plugin scheduler: run iceberg and lifecycle lanes concurrently (#8821)
* plugin scheduler: run iceberg and lifecycle lanes concurrently

The default lane serialises job types under a single admin lock
because volume-management operations share global state. Iceberg
and lifecycle lanes have no such constraint, so run each of their
job types independently in separate goroutines.

* Fix concurrent lane scheduler status

* plugin scheduler: address review feedback

- Extract collectDueJobTypes helper to deduplicate policy loading
  between locked and concurrent iteration paths.
- Use atomic.Bool instead of sync.Mutex for hadJobs in the concurrent
  path.
- Set lane loop state to "busy" before launching concurrent goroutines
  so the lane is not reported as idle while work runs.
- Convert TestLaneRequiresLock to table-driven style.
- Add TestRunLaneSchedulerIterationLockBehavior to verify the scheduler
  acquires the admin lock only for lanes that require it.
- Fix flaky TestGetLaneSchedulerStatusShowsActiveConcurrentLaneWork by
  not starting background scheduler goroutines that race with the
  direct runJobTypeIteration call.
