[email protected], systemd-fsck-root.service, systemd-fsck-
usr.service, systemd-fsck - File system checker logic

systemd-fsck-usr.service
/usr/lib/systemd/systemd-fsck
[email protected], systemd-fsck-root.service, and
systemd-fsck-usr.service are services responsible for file system
checks. They are instantiated for each device that is configured
for file system checking. systemd-fsck-root.service and
systemd-fsck-usr.service 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.
[email protected] is used for all other file systems and for
the root file system in the initrd.
These services are started at boot if passno in /etc/fstab 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
"noauto" 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.
systemd-fsck does not know any details about specific
filesystems, and simply executes file system checkers specific to
each filesystem type (fsck.type). These checkers will decide if
the filesystem should actually be checked based on the time since
last check, number of mounts, unclean unmount, etc.
systemd-fsck-root.service and systemd-fsck-usr.service will
activate reboot.target if fsck returns the "System should reboot"
condition, or emergency.target if fsck returns the "Filesystem
errors left uncorrected" condition.
[email protected] will fail if fsck returns with either
"System should reboot" or "Filesystem errors left uncorrected"
conditions. For filesystems listed in /etc/fstab without "nofail"
or "noauto" options, "local-fs.target" will then activate
emergency.target.
systemd-fsck understands these kernel command line parameters:
fsck.mode=
One of "auto", "force", "skip". Controls the mode of
operation. The default is "auto", and ensures that file
system checks are done when the file system checker deems
them necessary. "force" unconditionally results in full file
system checks. "skip" skips any file system checks.
Added in version 186.
fsck.repair=
One of "preen", "yes", "no". Controls the mode of operation.
The default is "preen", and will automatically repair
problems that can be safely fixed. "yes" will answer yes to
all questions by fsck and "no" will answer no to all
questions.
Added in version 213.
