I'm looking for systemd's equivalent to the shutdown -F command. I know that I can force fsck by adding fsck.mode=force to kernel options or tweak mount count for disks. I have tried touch /forcefsck but it doesn't work with latest systemd versions.

When I want to force fsck, I just use the following command:

# tune2fs -C 50 /dev/sda2

It simply sets the mount counter to 50, but I also have set:

# tune2fs -l
Mount count:              18
Maximum mount count:      20

So as you can see, when I set 50 in mount count, kernel thinks it should fsck the partition.

This solution works always, no matter what you use sysvinit/systemd or whatever else.


systemd's shutdown -F equivalent is systemctl poweroff. I haven't figured out the relation with fsck. However, AFAIK, you can not force fsck using systemd, because fsck is executed before systemd starts.

  • If you add -F flag to shutdown command it will force fsck execution after reboot: unixhelp.ed.ac.uk/CGI/man-cgi?shutdown

    It just passes fsck.mode=force to the kernel. With systemd I guess you can't AFAIK.

    systemd is init, i.e. the very first program executed, so fsck necessarily takes place after systemd is run.
