failover IP

I ran packemaker http://clusterlabs.org/wiki/Debian_Lenny_HowTo instructions and chose openais.
Nods if both are included in the IP is enabled. If I disable one node is the IP address is disabled and is not running on the second node. What should I add to the IP switched to next node?

first of all, read the output, and try to figure out what you cluster is trying
to tell you. "no quorum" really means "no quorum".

@beekhof: You should make the "WITHOUT" blinking.

Then read the FAQ:

http://www.clusterlabs.org/wiki/FAQ#I_Killed_a_Node_but_the_Cluster_Didn.27t_Recover

This question was asked quite often so that is why it was added to the
frequently asked questions.
