Resync part of scheduled scrub excessively long
Previous scheduled scrubs on my backup NAS have taken 5 days. The BTRFS portion of the currently active scrub task took 3 days, but I don't know if that's typical -- I don't typically look. But wha...
Five days does seem unusually long, especially compared with the 628X running the same drives. Since the drives aren't reporting errors, I'd be interested in whether the resync is actually being limited by the NAS rather than the disks.
One thing I'd check is the actual resync speed in /proc/mdstat over a few minutes while the backup jobs are running and again when they're stopped. If the speed changes significantly, the workload may be competing with the resync. It may also be worth checking the RAID layout and current array state, since a resync after a particular type of array event can behave differently from a routine maintenance operation.
It's my backup unit. The shares don't even allow SMB access, only RSYNC. The only other task is the daily backups, which are occurring as normal. And none of this has changed except the used space and number of files, which is a very small change WRT the volume size.
