Restart and wait for the log replay to finish. + 1. Empty the commitlog with "nodetool drain." - 1. Shutdown Cassandra and verify that there is no remaining data in the commitlog. (as of 0.6, you can do this using "nodetool drain") + 1. Shutdown Cassandra and verify that there is no remaining data in the commitlog. 1. Delete the sstable files (-Data.db, -Index.db, and -Filter.db) for any CFs removed, and rename the files for any CFs that were renamed. 1. Make necessary changes to your storage-conf.xml. 1. Start Cassandra back up and your edits should take effect.
