9.5. Repairing an XFS File System
xfs_repair utility cannot repair an XFS file system with a dirty log. To clear the log, mount and unmount the XFS file system. If the log is corrupt and cannot be replayed, use the
-L option ("force log zeroing") to clear the log, i.e.
xfs_repair -L . Note, however, that this may result in further corruption or data loss.
