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
