fsck.btrfs(8)fsck.btrfs(8)NAMEfsck.btrfs - do nothing, successfully
SYNOPSISfsck.btrfs [-aApy] [device...]
DESCRIPTIONfsck.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(8) subcommand 'check'. By default the
filesystem consistency is checked, the repair mode is enabled via
--repair option (use with care!).
The options 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 code returned:
0 No errors
8 Operational error, eg. device does not exist
