redhat 6 version + xfs_repair or fsck.xfs in order to fix corrupted file-system

by

we have redhat machines version – 6.x

all disks that mounted have xfs files system
as:

UUID=198s5364-a29c-429e-b16d-e772acd /data_SA              xfs     rw,noatime,inode64,allocsize=16m 1 2

we want to fix the file system on some of the disks,

what is the right approach to use

  1. xfs_repair
  2. fsck.xfs
  3. fsck

Answer

From the fsck man page:

   fsck.xfs  is called by the generic Linux fsck(8) program at startup to check and repair an XFS filesystem.  XFS is a journaling filesystem and performs recovery at mount(8) time if
   necessary, so fsck.xfs simply exits with a zero exit status.

   If you wish to check the consistency of an XFS filesystem, or repair a damaged or corrupt XFS filesystem, see xfs_repair(8).
