Tried adding different node. Same results. This looks like a bug somewhere deeper in the cluster stack. Could you try to manually propagate the conf file with ccs_tool and see what the error message is? After I remove the node, then try to add it back manually, here's what I see: [root@huey cluster]# ccs_tool update .cluster.conf Unable to open connection to dewey.lab.boston.redhat.com: Bad file descriptor Failed to update config file.

Sorry. About 5 minutes after I posted here, i realized that the cluster needs a restart when going from 3->2 and 2->3 nodes. That's what's causing the problem. Fixing Product Name. Cluster Suite was merged into Enterprise Linux for version 5.0. Marking this modified and depending on https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=240508 That fix will remove the need for any special handling on the part of conga for clusters going from > 2 nodes to 2 and from 2 to > 2. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
