Re: After loadbalance why does the size increase

Rather than use nodetool load balance, assign the tokens manually. See the section on load balancing here http://wiki.apache.org/cassandra/Operations

use nodetool move or set the tokens in the yaml.

I'm may be wrong here, but after the move run repair to make sure each node has all the data it should, then cleanup to remove data it should not have, then (perhaps) compact to trigger GC and clean up any un used files.

(brain is a little fuzzy today, so please excuse any stupids :) )
