repair file system by edit the fstab file

  • 772

is it possible to run xfs repair by re-edit the fstab file?

/dev/mapper/vg-linux_root /                       xfs     defaults        0 0
UUID=7de1dc5c-b605-4a6f-bdf1-f1e869f6ffb9 /boot   xfs     defaults        0 0
/dev/mapper/vg-linux_var /var                     xfs     defaults        0 0
/dev/mapper/vg-linux_swap swap                    swap    defaults        0 0

I am not sure but by replace the last number from 0 to 1 , is it right?

  1. Best Answer

    The format of fstab should be :

    (Device)  (MountPoint) (FsType) (MountOptions)  (Dump) (FsCheck)

    So here FsCheck field can take one of the below values :

    0 : fsck is disabled

    1 : fsck is enabled with more priority ( mainly for root filesystems )

    2 : fsck is enabled for other filesystems with less priority.

    So you have to choose one of these options.

  2. No, a positive passno (6th fstab field) is not sufficient. Yes, it still should be 1 for / and 2 otherwise.

    Specific to XFS, fsck.xfs by default does not do anything. Journal recovery at mount may get it into a usable state. But if that fails, the system won't boot, usually requiring booting a rescue target to recover.

    However, the system administrator can force fsck.xfs to run xfs_repair(8) at boot time by creating a /forcefsck file or booting the system with "fsck.mode=force" on the kernel command line.
