Linux – How to check fsck results, ran at boot, on remote machine

shutdown -rF now

Should force a fsck of all disks in /etc/fstab on reboot. link: man shutdown

Alternatively, if you want a fsck on every reboot:

cd /
touch forcefsck
reboot

Ok, so i found out on CentOS you can do this:

touch /forcefsck
echo -n "-ys" > /fsckoptions

to get a log of what fsck did i had to go on a harder route:
Warning: do this at your own risk, i have no ideia of what implications this could have if goes wrong

Edited the /etc/rc.sysinit (don't forget to backup) to get the desired behaviour:

from line 500 (changing the -C to -V gets rid of progress bars)

if [ "$BOOTUP" = "color" ]; then
       fsckoptions="-C $fsckoptions"
else
       fsckoption="-V $fsckoptions"

from line 648 changed the block that ran fsck to look like this:

outputtt="$(fsck -T -t noopts=_netdev -A $fsckoptions)"
mount -n -o remount,rw /
echo $outputtt > /var/log/fsckoutput
mount -n -o remount,ro /

one small perk is that it won't conserve new lines, but its readable in times of dire need.
Thanks for all the help.
