<title>Description</title>
|
|
|
|
<para><filename>systemd-fsck@.service</filename>, <filename>systemd-fsck-root.service</filename>, and
|
|
<filename>systemd-fsck-usr.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> and <filename>systemd-fsck-usr.service</filename> are
|
|
responsible for file system checks on the root and /usr file system, respectively, but only if the root
|
|
filesystem was not checked in the initrd. <filename>systemd-fsck@.service</filename> is used for all
|
|
other file systems and for the root file system in the initrd.</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, but only if it is also configured to be
|
|
mounted at boot (i.e. without <literal>noauto</literal> option). 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>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><filename>systemd-fsck-root.service</filename> and <filename>systemd-fsck-usr.service</filename>
|
|
will activate <filename>reboot.target</filename> if <command>fsck</command> returns the "System
|
|
should reboot" condition, or <filename>emergency.target</filename> if <command>fsck</command>
|
|
returns the "Filesystem errors left uncorrected" condition.</para>
|
|
|
|
<para><filename>systemd-fsck@.service</filename> will fail if
|
|
<command>fsck</command> returns with either "System should reboot"
|
|
or "Filesystem errors left uncorrected" conditions. For filesystems
|
|
listed in <filename>/etc/fstab</filename> without <literal>nofail</literal>
|
|
or <literal>noauto</literal> options, <literal>local-fs.target</literal>
|
|
will then activate <filename>emergency.target</filename>.</para>

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.
