+Repair corrupt or damaged XFS filesystem on C<device>.
+
+The filesystem is specified using the C<device> argument which should be
+the device name of the disk partition or volume containing the filesystem.
+If given the name of a block device, C<xfs_repair> will attempt to find
+the raw device associated with the specified block device and will use
+the raw device instead.
+
+Regardless, the filesystem to be repaired must be unmounted, otherwise,
+the resulting filesystem may be inconsistent or corrupt.
+
+The returned status indicates whether filesystem corruption was
+detected (returns C<1>) or was not detected (returns C<0>)." };
