| |
| − | fsck.btrfs - do nothing, successfully
| |
| − |
| |
| − | ==SYNOPSIS==
| |
| − |
| |
| − | <p><b>fsck.btrfs</b> [-aApy] [<em><device></em>…]</p>
| |
| − | ==DESCRIPTION==
| |
| − |
| |
| − | <p><b>fsck.btrfs</b> is a type of utility that should exist for any filesystem and is
| |
| − | called during system setup when the corresponding <tt>/etc/fstab</tt> entries
| |
| − | contain non-zero value for <tt>fs_passno</tt>, see [http://man7.org/linux/man-pages/man5/fstab.5.html fstab(5)] for more.</p>
| |
| − | <p>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.</p>
| |
| − | <p>If you wish to check the consistency of a BTRFS filesystem or repair a damaged
| |
| − | filesystem, see [[Manpage/btrfs-check|btrfs-check(8)]]. By default filesystem consistency is checked,
| |
| − | the repair mode is enabled via the <em>--repair</em> option (use with care!).</p>
| |
| − | ==OPTIONS==
| |
| − |
| |
| − | <p>The options are all the same and detect if <b>fsck.btrfs</b> is executed in
| |
| − | non-interactive mode and exits with success,
| |
| − | otherwise prints a message about btrfs check.</p>
| |
| − | ==EXIT STATUS==
| |
| − |
| |
| − | <p>There are two possible exit codes returned:</p>
| |
| − | <dl>
