# man xfs_repair
       -d     Repair dangerously. Allow xfs_repair to repair an XFS filesystem
              mounted read only. This is typically done on  a  root  fileystem
              from single user mode, immediately followed by a reboot.

# mount
/dev/hda3 on /mnt type xfs (ro)
# xfs_repair /dev/hda3
xfs_repair: /dev/hda3 contains a mounted filesystem

fatal error -- couldn't initialize XFS library
# xfs_repair -d /dev/hda3
Phase 1 - find and verify superblock...
