[SOLVED] Garbage collector error due to datastore full

2023-11-21T14:12:24+01:00: starting garbage collection on store ZFS_4To
2023-11-21T14:12:24+01:00: Start GC phase1 (mark used chunks)
2023-11-21T14:12:24+01:00: TASK ERROR: update atime failed for chunk/file "/mnt/datastore/ZFS_4To/.chunks/4ee6/4ee6e60f7845053afd2256fabae60bfbabc6303246c262983d511246be68133f" - ENOSPC: No space left on device
 
after moving some chunks directory to local drive to free up space on datastore, i could run garbage collector normally and it free spaces.
then i move again directoies to datastore and re-run garbage collector...
i also change the backup config to remove/change some vm from backup
