.SH "NAME"
systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck \- File system checker logic
.SH "SYNOPSIS"
.PP
systemd\-fsck@\&.service
.PP
systemd\-fsck\-root\&.service
.PP
/usr/lib/systemd/systemd\-fsck
.SH "DESCRIPTION"
.PP
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\&.
.PP
These services are started at boot if
\fBpassno\fR
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\&.
.PP
systemd\-fsck
does not know any details about specific filesystems, and simply executes file system checkers specific to each filesystem type (/sbin/fsck\&.*)\&. These checkers will decide if the filesystem should actually be checked based on the time since last check, number of mounts, unclean unmount, etc\&.
.PP
If a file system check fails for a service without
\fBnofail\fR, emergency mode is activated, by isolating to
emergency\&.target\&.
.SH "KERNEL COMMAND LINE"
.PP
systemd\-fsck
understands these kernel command line parameters:
.PP
\fIfsck\&.mode=\fR
.RS 4
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\&.
.RE
.PP
\fIfsck\&.repair=\fR
.RS 4
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\&.
