We recently increased the replication factor of a keyspace in our cassandra 1.1.1 cluster from 2 to 4. This was done by setting the replication factor to 4 in cassandra-cli, and then running a repair on each node.
Everything seems to have worked; the commands completed successfully and disk usage increased significantly. However, if I perform a describe on the keyspace, it still shows replication_factor:2. So, it appears that the replication factor might be 4, but it reports as 2. I'm not entirely sure how to confirm one or the other. Since then, I've stopped and restarted the cluster, and even ran an upgradesstables on each node. The replication factor still doesn't report as I would expect. Am I missing something here? - .Dustin
