No. cman and gulm do the same thing, so only one of them is needed. gulm also does fencing a little differnt than cman. Cman talks to the fenced program to fence a node, gulm execs fence_node. > 2) Do I need to list all nodes in the cluster.conf, or just lock servers? > I realize I need to list lock servers separately in the <gulm> section, > and lock servers need to be listed as <clusternode>'s, but do the other > boxes also need to be listed? All of the nodes must be listed.

The <gulm> section cannot change while gulm is running anywhere in the cluster. The other sections can change when ever. -- Michael Conrad Tadpol Tilstra Sanity is the playground for the unimaginative.
