Hello,
I was gone for 2 days from my house and that's why I disconnected the electricity from my R820 server, and now I'm back and I haven't been able to start the pve.
When trying to start it I get this error ( https://i.imgur.com/T8S18jk.png ) repeatedly and at the end I get a busybox terminal.

Did you add any USB sticks/disks or something similar that sda might be called sdb now?
