Step 1: configure two of the new hosts to be part of a 5 node cluster containing all of the original nodes.
Step 2: reconfigure each of the original 3 nodes to be part of the the 5 node cluster. Step 3: bounce each of the originals and start the two new servers. Step 4: configure the 6th server (previously untouched) to be part of a three node cluster containing only the 3 new nodes. Step 5: reconfigure servers 4 and 5. Step 6: bounce servers 4 and 5 and start server 6. Done. (wait for somebody else to critique this procedure before proceeding with it) On Tue, May 10, 2011 at 7:54 AM, Murali Krishna.
