Re: Skipping fsck during boot with systemd?

[Marc Auslander <marcslists@gmail.com>]

Long ago, I decided that inconvenient fsck's were not what I
needed. And that cancelling them was not an option - I run quasi
headless so there's no way.

So - I use tune2fs to set a ridiculous reboot count for automatic
fsck.  Then a run a cron job the does a reboot with the -F option once
a month in the middle of the night when I don't need the machine.

systemd won't change a thing for me.

cron job follows.  it actually checks for a disk that needs an fsck.

#!/bin/bash
#check for fsck needed and force it and reboot if needed
[ "$1" = -force ] && force=yes
month=$(date +%b)
reboot=no
while read disk rest
do
    lastfsck=$(tune2fs -l $disk | grep 'Last checked:')
    lastfsck=${lastfsck:30:3}
    [ "$lastfsck" = "$month" ] || reboot=yes
done << --end
$(df | egrep '^/dev')
--end
if [ "$force" != yes ]
then
    [ $reboot = no ] && exit
    if [ -n "$(who)" ]
    then
	echo 'Not rebooting because of logged on users'
	who
	exit
    fi
fi
echo 'checkfsck rebooting' | mail -s checkfsck root
# -F below forces check of all filesystems, not just root
echo 'checkfsck rebooting'
shutdown -rF now
sleep 120
echo 'shutdown seems to be broken again'
shutdown -nrF now
sleep 120
echo 'shutdown -n seems to have failed'
sleep 120
touch /forcefsck
sync;sync;sync;sleep 60;reboot -f
sleep 120
echo 'it just wont die - need help'
