My xpenolgy VM crashed after I copied all my data. I got a nasty Volume 1:crashed.
I can get the results from cat /proc/mdstat and everything seems ok:

Hello everyone, I'm a bit desperate here!
My xpenolgy VM crashed after I copied all my data. I got a nasty Volume 1:crashed.
I can get the results from cat /proc/mdstat and everything seems ok:
