Swap partition not mounted after upgrade to openSUSE 13.1

Hello,

i upgraded my system from 12.3 to 13.1 shown in http://linux.t-tietz.de/OpenSUSE_Upgrade_12_3__13_1 - all works fine but at reboot no swap partition is mounted. The boot sequence shows a Failed for mounting the swap.

What to do?

thanks in advance

What do;
cat /var/log/messages | grep -i swap
and
systemctl status swap.target

say?

Please put the output in CODE tags


Like this!

thanks @miuku

the outputs are


# cat /var/log/messages | grep -i swap

Please copy paste the output of: free

If you have “swap” showing active in free on the last line, please check /etc/fstab for a device with the line swap in it and remove that line as this is no longer required, swap gets probed by systemd. Make a backup of the fstab file first.

Then on the next boot, check if the issue persists.

the output of free:

seems the swap is in use or?

Yes, you should remove the swap from fstab and see the next time you reboot if the systemd still reports swap target as a failure.

It shouldn’t.

many thanks @miuku no failure reported on system boot
