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/mdstat
There 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.
