fsck of a file system, say the root, during the next rebooting of Linux?
2 possible ways:
/forcefsck way for
# touch /forcefsck
and reboot. Next time the / will be fsck’ed .
Add these 2 kernel boot parameters:
What these 2 kernel parameters do:
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.
