fsck.btrfs - do nothing, successfully
fsck.btrfs [-aApy] [<device>...]
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!).
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.
There are two possible exit codes returned:
- 0
- No error
- 8
- Operational error, e.g. device does not exist
