FSCK.BTRFS(8)                              Btrfs Manual                             FSCK.BTRFS(8)

NAME
       fsck.btrfs - do nothing, successfully

SYNOPSIS
       fsck.btrfs [-aApy] [...]

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 the filesystem consistency is checked, the repair mode is
       enabled via --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
