mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
[root@atyu30 ~]# xfs_repair -L /dev/sdc1
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...

Phase 5 - rebuild AG headers and trees...
- reset superblock...
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- traversing filesystem ...
- traversal finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
resetting inode 128 nlinks from 5 to 4
resetting inode 247 nlinks from 2 to 497
