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 codes returned:
|
|
|
|
0::
|
|
No error
|
|
|
|
8::
|
|
Operational error, eg. device does not exist
