systemd-fsck(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 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.*). This helper 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

   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.
