Thanks for that hint. I didn't realize the results of starting ha =
services for the cluster or starting it for just one node are quite =
different if only one node is available at startup:

start ha services for cluster:=20
	* membership only comes up if tiebreaker node is available,=20
	* unavailable node gets reset
	* node status is 1x UP, 1x DOWN
	* bringing up resource groups fails.

start up ha services just for the available node:=20
	* membership comes up regardles of tiebreaker node
	* unavailable node doesn't get reset
	* node status is 1x UP, 1x inactive
	* bringing up resource groups works.

I feel much better now that I have known-to-work recipiece for bringing =
up services even from "both-nodes-down, one node kaputt" status.=20

That said, I still don't understand where the first case differs from =
starting up with both nodes present and then loosing one :-)

Thanks again, Martin
