After a power failure during server installation of CentOS, the external storage system that contains user data could not be mounted due to failed superblocks. I performed an xfs_repair on the system, which worked fine, but only the directories that are owned by root appear after the file system is mounted.
The file system is a Dell MD3200 with 4 LUNS that are assembled in raid 0 via mdadm. Prior to the power outage, the LUNS were detected as /dev/dm-0, /dev/dm-1, etc. After the xfs_repair they appear as /dev/sd* instead as the LUNS are no longer recognized as virtual disks (generated by Dell MDSA).
I would greatly appreciate any help. Thank you.
