FSCK.BTRFS(8)                        BTRFS                       FSCK.BTRFS(8)

NAME
       fsck.btrfs - do nothing, successfully

SYNOPSIS
       fsck.btrfs [-aApy] [<device>...]

DESCRIPTION
       fsck.btrfs  is  a  type of utility that should exist for any filesystem
       and is called during system setup when the corresponding /etc/fstab en‐
       tries contain non-zero value for fs_passno, see fstab(5) for more.

       Traditional filesystems need to run their respective  fsck  utility  in
       case  the  filesystem was not unmounted cleanly and the log needs to be
       replayed before mount. This is not needed for  BTRFS.  You  should  set
       fs_passno to 0.

       If  you wish to check the consistency of a BTRFS filesystem or repair a
       damaged filesystem, see btrfs-check(8). By default  filesystem  consis‐
       tency  is  checked,  the repair mode is enabled via the --repair option
       (use with care!).

OPTIONS
       The options are all the same and detect if fsck.btrfs  is  executed  in
       non-interactive mode and exits with success, otherwise prints a message
       about btrfs check.

EXIT STATUS
       There are two possible exit codes returned:

       0      No error

       8      Operational error, e.g. device does not exist

FILES
       /etc/fstab

SEE ALSO
       btrfs(8), fsck(8), fstab(5)
