I've managed to break my server

[stetho]

Yesterday I managed to pull the wrong power cable out of my UPS (follow the cable - definitely this one...) and cut the power to my Unraid server.

 

Long story short - after powering it back on I get a GUI but nothing works. I'm resigned to rebuilding it after 24 hours of trying everything I've found on Google. My /mnt/user is missing (/mnt/user0 is there) and any kind of disk activity produces the same error

 

root@Tower:~# df -h
df: /mnt/user: Transport endpoint is not connected

So as a last resort I've added the diagnostics to this post in case someone can spot what Google isn't showing me.

Thanks

It's your cache drive's file system that got corrupted when you did that.  Wait for the resident guru @JorgeB

Yes cache is corrupt and needs to be re-formatted, some recovery options here if needed, but that's not the only issue, shfs also crashed later, that's what's causing those "transport endpoint" errors:

You'll need to reboot to fix that.
