SYNOPSIS         top

       systemd-fsck@.service

       systemd-fsck-root.service

       /usr/lib/systemd/systemd-fsck

DESCRIPTION         top

       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         top

       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.
