FSCK.BTRFS(8)                         Btrfs Manual                        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 code returned:

       0
           No error

       8
           Operational error, eg. device does not exist

FILES
       /etc/fstab
