systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck — File system checker logic
systemd-fsck@.service
systemd-fsck-root.service
/usr/lib/systemd/systemd-fsck
systemd-fsck@.service is a
service responsible for file system checks. It is
instantiated for each device that requires a file
system
check. systemd-fsck-root.service is
responsible for file system checks on the root
file system.
systemd-fsck will
forward file system checking progress to the
console. If a file system check fails, emergency mode
is activated, by isolating to
emergency.target.
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.
