I am on OMV 3.0.99
I tried getting into it today, and all my file shares were broke, and the file systems page says that my /dev/sda1 is online, but not mounted. I try to mount it, but it gives me the error:
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; mount -v --source '/dev/sda1' 2>&1' with exit code '32': mount: /dev/sda1: can't read superblock
I don't see any angry LEDs on my server for failed/degraded drives...
Its on a Dell R710 Perc6i
I actually not remember the model of the drives in the raid.. I want to say the are all WD Blues. There are 5 of them Raid5 with 7.28TB so its 4x2TB drives if I remember correctly.
I don't think I have had a power loss on them recently other than me actually shutting it down a few weeks ago for some wire management... otherwise I havent touched the config or hardware in weeks (maybe months).
I tried:
mdadm --assemble /dev/sda
mdadm: device /dev/sda exists but is not an md array.
mount /dev/sda1
mount: /dev/sda1: can't read superblock
sudo mdadm --verbose --assemble --force /dev/sda1
mdadm: device /dev/sda1 exists but is not an md array.

I would like to keep my data... it's not world ending since most of my personal junk is backup to my google drive, and some to my old NAS, but I do have a lot of media on here that would be annoying to re-download.
Not really sure where to go from here... Any help would be appreciated!
