SYNOPSIS         top




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


       systemd-fsck understands these kernel command line parameters:

           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.
           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.
