NAME         top

       systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck -
       File system checker logic

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 only if the root filesystem was not
       checked in the initramfs.  systemd-fsck@.service is used for all
       other file systems and for the root file system in the initramfs.

       These 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 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 (/sbin/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.

       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 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.

       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.
