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 entries 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 consistency 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
