Cache drives unmountable out of nowhere

Featured Replies

Things have been running fine with no issues. I went to open Sonarr and it didn't load, so I rebooted my machine. When it came back up, I saw the error that both of my cache drives are unmountable. I haven't done anything to mess with them, so this is all sort of sudden. I've attached my diagnostics and am crossing my fingers that it's an easy fix. 

 

Thank you.

If it's just a log problem you might get it back after running this:

btrfs rescue zero-log /dev/nvme1n1p1

That worked! Thank you so much, JorgeB.

 

Just so I know, is there anything I should/should not be doing to make sure something like this doesn't happen again?

Not sure what would cause that, no unclean shutdown right?

Nope. I saw that sonarr/radarr weren't working and went into the interface, which was still working as usual, and ran a restart command through there.

Not sure then, hopefully a one time thing.

Thank you nonetheless. You are a lifesaver!

The same thing just happened when I tried accessing my dockers this afternoon. I ran the command above and it started working again. There were no unclean shutdowns, and I don't think I even rebooted the machine at all since it went back up.

 

I assume it's a configuration issue, so I uploaded a new diagnostics file. Is there anything I should try doing to fix it?

At this point I would recommend backing up and re-formatting the pool to create a new filesystem.
