Unmountable drive following power failure

[bilr514]

Hi.  I'm fairly new to Unraid, having only been using it for the last year or so to run my Plex server.

 

I had a power outage about 3 days ago and my Unraid server unfortunately abruptly lost power as I was unable to make it to my tower prior to the UPS draining.

 

When I powered it back up, I got a message saying Disk 1 was "Unmountable: Not Mounted".  I found a few other threads on here where users have had similar issues, so I tried a few things they did including a smart disk check and a parity check...From what I could see, the smart disk check returned with no issues.  The parity check had more than 15,000 errors that it resolved.  Unlike the other thread mentions here:

 

 

following my parity check and reboot, the disk remains unmountable.  I haven't done anything further because, as I mentioned earlier, I'm a noob and am not sure what to do to save my data on disk 1.  Any advice would be appreciated.

Sounds like you did a correcting parity check. A bad idea in your situation. 

 

Attach Diagnostics to your NEXT post in this thread.

The thread you linked talks about check filesystem, which is the correct way to deal with unmountable, but you don't mention even trying that.

See attached files for requested diagnostics.  Again, my apologies but I am new to this (at least troubleshooting issues with it anyway).

What I actually did was execute a smart test...Here are the results of that:

Thanks for taking the time to look.

Check filesystem on disk1.

Run it again without -n or nothing be done, and if it asks for -L use it.

[bilr514]

Had to use -L

output looks good, so If you restart the array in Normal mode the drive should now mount without any issues.

Thanks for your help!  It is now mounted and a parity check kicked off automatically...

 

The problem I'm seeing now is that my docker service failed to start.

Post new diagnostics

Here you go...Thanks again!

Delete and recreate the docker image.

[bilr514]

That got it JorgeB...Thanks!

 

I wish I could say my troubles are over, however, I can't access Plex.  After reinstalling, it says that Plex is unhealthy...In anticipation, I've rerun diagnostics.

Sorry, cannot help with Plex since I've never used it, someone else might or repost in the existing support thread/discord for that container, assuming one exists.
