systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck — File system checker logic






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. The root file system check is performed before the other file systems. Either service is enabled at boot if passno in /etc/fstab for the file system is set to a value greater than zero.

systemd-fsck will forward file system checking progress to the console. If a file system check fails, emergency mode is activated, by isolating to

Kernel Command Line

systemd-fsck understands one kernel command line parameter:


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.
