Greetings!
Backup server was acting up and the issue was the drives (all of them)
:( Could use some guidance or verdict.
It has a total of 6 drives: sda,b,c,d,e,f. From the superblock info
(attached), there is a raid 1, and a raid 10 volume. Problem is all
the disks are part of both raid volumes (according to superblock).
I am currently booted into an ubuntu live disk shell.
Raid 1 : sde2(0) sdb2(1) sdc2(s) sdd2(s) sdf2(s)
- > 2 devices
- > contains the boot partition. I was able to mount this.
Raid 0: sdc3(2) sdd3(3) sde3(4) sdf3(5)
- > 6 Devices
- > currently inactive
Again, attached are the superblocks, dmseg output.
