3.v. Repairing an XFS File System

To repair an XFS file organization, utilise xfs_repair: 

                      #                                            xfs_repair                        /dev/device

The xfs_repair utility is highly scalable and is designed to repair fifty-fifty very large file systems with many inodes efficiently. Unlike other Linux file systems, xfs_repair does not run at boot time, even when an XFS file organisation was not cleanly unmounted. In the effect of an unclean unmount, xfs_repair simply replays the log at mount fourth dimension, ensuring a consistent file system.

The xfs_repair utility cannot repair an XFS file system with a muddied log. To clear the log, mountain and unmount the XFS file system. If the log is corrupt and cannot exist replayed, use the -50 option ("force log zeroing") to articulate the log, that is, xfs_repair -L /dev/device . Be enlightened that this may upshot in further corruption or data loss.
