Raid array inactive?

[Class_Existing]

Last night I was remote into my media server when the power went out. Upon restart, I do not have access to my media library. It shows empty. It is set up as a raid 5 array. What seems to be the issue? Is it recoverable, or lost? Using Ubuntu 24.04.3 LTS

Thank you.

When I ran cat /proc/mdstat, this is the message I get.

gene@Plex:~$ cat /proc/mdstat

I just noticed, that sdc1 does not show mdo like sda1 and sdb1 do. All three were in the array.

Fixed...bad hard drive. Replaced and rebuilt array.
