Cache drive unmountable

[JeffreyVrancken]

My girlfriend called me to Plex wasn't responding. I wasn't able to login remotely, so I called her and asked her to login to the webUI, which wasn't possible. I then asked her to do a hard reboot. 

 

When I came home tonight I saw the problem "Unmountable: No file system" on my cache drive. However I'm not sure if that was the initial problem, maybe it was the hard reboot.

 

With the Check Filesystem Status option I got the following:

checksum verify failed on 1074298880 found E2CF063C wanted 54F640E1

checksum verify failed on 1074298880 found E2CF063C wanted 54F640E1

Csum didn't match

ERROR: cannot open file system

enabling repair mode

 

After setting --repair as an option I got the same.

 

What are my options?

 

Here are my diagnostics

I'm not very good at command line etc, but I'm able to follow instructions if needed.

 

Thanks!

I came to my senses and realized it's only my cache drive with nothing special on it.

 

I'm in the process of restoring the backup of my appdata to an array disk, that's all I lost with this failure. (I love that plugin!)

I'm assuming that I can just format the cache drive and afterwards everything will be moved back (appdata is set to cache prefer)

Is there something I'm overseeing? What with the docker image that is set to /mnt/user/system/docker/docker.img?

 

And can anyone confirm that this will work?

If there's important data on the cache device you can use this FAQ entry to try and recover, if not just restore from backups, docker image will be recreated.
