File system checker logic
Синопсис (Synopsis)
systemd-fsck@.service
systemd-fsck-root.service
/usr/lib/systemd/systemd-fsck
Описание (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.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.
Командная строка ядра (Kernel command line)
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.
