systemd-fsck-root.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 is
responsible for file system checks on the root file
system, but in only if the root filesystem wasn't
checked in the initramfs.
systemd-fsck@.service is used for
all other file systems and for the root file system in
the initramfs.Those services are started at boot if
in
/etc/fstab 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 one 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 (/sbin/fsck.*).
This helper will decide if the filesystem should
actually be checked based on the time since last
check, number of mounts, unclean unmount, etc.systemd-fsck will forward
file system checking progress to the console. If a
file system check fails for a service without
, emergency mode is activated,
by isolating to
emergency.target.Kernel Command Linesystemd-fsck understands
one kernel command line parameter: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.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.
