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
