DESCRIPTION
|
|
|
|
|
-----------
|
2014-05-19 15:49:35 +00:00
|
|
|
*fsck.btrfs* is a type of utility that should exist for any filesystem and is
|
2014-04-02 08:29:36 +00:00
|
|
|
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!).
