Stuck scrubbing

I can take a screenshot of the front door, but IMHO it doesn't seem to help

My readynas seems to be stuck in scrubbing mode.   I cannot access shares, access the the UI, nor access via ssh.

Is this safe to rebooot?

What model NAS?  

What firmware is it running?

What status does RAIDar give you?

Try downloading the log zip from RAIDar (might not work but worth a try).

Does the NAS respond to ping?

"Stuck" for how long?  Do you run scrubs on a schedule?  If so, what is the typical duration?  A scrub can take a very long time, especially if you have SMR drives.  On units with a lesser CPU, it can "take over", essentially locking you out of the GUI and SMB.  But SSH is typically still able to connect, so that's different for you.

I had an issue on one of my NAS that seemed to lock up the scrub.  But it was a rack-mount unit with a powerful enough CPU that it was still accessible via SMB and the GUI.  What I found was doing it was a very large file that was fragmented.

A "scrub" on a ReadyNAS actually does a BTRFS scrub and an MDADM re-sync.  While both are usually safe to interrupt with a power cycle, it's not recommended.  And with two ongoing things that could go wrong, that doubles the chance of something bad happening.
