Scrub Stuck on 56.67%
My NAS unit has been stuck on Scrub at 56.67% for a few days now, how do I fix this?

Rebooting will cancel it, though of course then you won't know what is hanging it up.
You could query the status with ssh, if that is enabled.
How do I query the status with ssh, I think it's enabled.

Log in as root, using the NAS admin password.
There are actually two scrubs going on in parallel - btrfs and RAID.
To check the RAID status you can enter
cat /proc/mdstatThere should be a line in there that shows resync status (and estimated finish time).
To check the BTRFS scrub status you can enter
btrfs scrub status /data(assuming XRAID here - use your actual volume name if you are using FlexRAID).
If you have disk spindown enabled, it might go faster if you disable it for a while. Another thing you might consider is downloading the log zip file from the admin ui, and look for any btrfs or disk-related errors.
