[CentOS] Cluster Services

Hello, we are running CentOS 4.3 and the latest cluster suite packages from the csgfs yum repository for this release and need to delete a cluster member. According to the documentation we need to restart all cluster related services on all remaining nodes in the cluster after the node has been removed. This is a four node cluster so removing one node obviously degrades the cluster to three nodes, but we can have the remaining cluster members recalculate the number of votes to remain quorate. It still surprises me that we have to bring down the entire cluster just because we are deleting a node. Any feedback as to why this might be?
