I need a simple failover Cluster, if the drbs/fs_mount ist ok and
libvirt is started after that in all cases i dont have problems.

But from time to time the slave dont see that the master is gone
when i plug out the power of the active/master.

And also from time to time (when i test power loss/reboot etc)
i have to start drbd / libvirt manualy - in all cases it can be
"repaired" - but i need to automate it as good as it can.
