<title>Description</title>
|
|
|
|
<para><filename>systemd-fsck@.service</filename> and
|
|
<filename>systemd-fsck-root.service</filename> are services
|
|
responsible for file system checks. They are instantiated for each
|
|
device that is configured for file system checking.
|
|
<filename>systemd-fsck-root.service</filename> is responsible for
|
|
file system checks on the root file system, but only if the
|
|
root filesystem was not checked in the initramfs.
|
|
<filename>systemd-fsck@.service</filename> is used for all other
|
|
file systems and for the root file system in the initramfs.</para>
|
|
|
|
<para>These services are started at boot if
|
|
<option>passno</option> in <filename>/etc/fstab</filename> for the
|
|
file system is set to a value greater than zero. The file system
|
|
check for root is performed before the other file systems. Other
|
|
file systems may be checked in parallel, except when they are on
|
|
the same rotating disk.</para>
|
|
|
|
<para><filename>systemd-fsck</filename> does not know any details
|
|
about specific filesystems, and simply executes file system
|
|
checkers specific to each filesystem type
|
|
(<filename>/sbin/fsck.<replaceable>type</replaceable></filename>). These checkers will decide if
|
|
the filesystem should actually be checked based on the time since
|
|
last check, number of mounts, unclean unmount, etc.</para>
|
|
|
|
<para>If a file system check fails for a service without
|
|
<option>nofail</option>, emergency mode is activated, by isolating
|
|
to <filename>emergency.target</filename>.</para>

<literal>force</literal>, <literal>skip</literal>. Controls

the mode of operation. The default is <literal>auto</literal>,

|
and ensures that file system checks are done when the file
|
|
system checker deems them necessary. <literal>force</literal>

unconditionally results in full file system checks.

checks.</para></listitem>

and will automatically repair problems that can be safely

fixed. <literal>yes</literal> will answer yes to all
