Roger has pointed an my error with my drbd config - various drbd
timeouts have to be adjusted for OpenSSI to make sure drbd and the
cluster membership stuff (CLMS) are in sync

In drbd.conf:

...
	net {
	    # timeout       60;    #  6 seconds  (unit = 0.1 seconds)
	    # connect-int   10;    # 10 seconds  (unit = 1 second)
	    # ping-int      10;    # 10 seconds  (unit = 1 second)
	
	    # Values for OpenSSI Cluster:

	    timeout	30;
	    connect-int	5;
	    ping-int	5;
	    ko-count	3;

With these changes OpenSSI/drbd seems a lot more reliable.   (Don't
forget to remake your initrd's after changing /etc/drbd.conf).

The correct defaults will be included in 1.9.3 final.
