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
