If you remove a node from a 3-node cluster you don't get a two-node cluster unfortunately. What you actually have is a 3-node cluster with one node removed and quorum artificially lowered. The two_node cluster (as in the cluster.conf key) is a special case in cman and requires a full cluster reboot to enable/disable the features that mean it can continue with only a single node active. If you need a 3 node cluster to keep running with only one active node you will need to configure a quorum device using qdiskd. |
