Subject Expanding 0.6.x cluster to multiple datacenters
Date Thu, 28 Jul 2011 00:44:06 GMT
I have a current 0.6.x cluster in a single datacenter with RackUnaware and
am looking to expand into a second data center. I know I need to change to
RackAwareStrategy however, I'm not sure what will happen to my data when I
restart the nodes in the current cluster before I even add the new DC. Will
the data need to move based on the rack each node is in or will it stay on
the node it is currently on? Also, when I start adding nodes in the new DC
to the cluster should they come in one at a time, like bootstrap, or should
I light up several at the same time to distribute the data?

For reference I have 19 nodes in my cluster.
