   9 # fsck.btrfs is a type of utility that should exist for any filesystem and is
  10 # called during system setup when the corresponding /etc/fstab entries contain
  11 # non-zero value for fs_passno. (See fstab(5) for more.)
  12 #
  13 # Traditional filesystems need to run their respective fsck utility in case the
  14 # filesystem was not unmounted cleanly and the log needs to be replayed before
  15 # mount. This is not needed for BTRFS. You should set fs_passno to 0.
  16 #
  17 # If you wish to check the consistency of a BTRFS filesystem or repair a
  18 # damaged filesystem, see btrfs(8) subcommand 'check'. By default the
  19 # filesystem consistency is checked, the repair mode is enabled via --repair
  20 # option (use with care!).
