Come on Davide, this is not your first post in this forum.

You should know in between which information is needed to recover a failed "mdadm" array.

How about "cat /proc/mdstat" as a starting point ?

Cheers,

Thomas

Sorry, you are right ananas

Result of cat /proc/mdstat is:

/dev/sdb seems to be member of the arryay, but the other drive is missing.

Please check the cables and the PSU

And if it really is:

Code

Raid Level : raid0

I hope you have a backup.

Good luck,

Thomas
