SYSTEMD-FSCK@.SERVICE(8) systemd-fsck@.service SYSTEMD-FSCK@.SERVICE(8)
NAME
systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck - File system checker logic
SYNOPSIS
systemd-fsck@.service
systemd-fsck-root.service
/lib/systemd/systemd-fsck
DESCRIPTION
systemd-fsck@.service and 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 passno 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 nofail, emergency mode is activated, by isolating to
emergency.target.
KERNEL COMMAND LINE
systemd-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.
