Bhanu M. Gandikota commented on CASSANDRA-7423: ----------------------------------------------- Hi I got the following error stack during "nodetool upgrades stables" [from 2.2.5 to 3.11.1]. What do I need to do ? -bash-4.2$ nodetool upgradesstables WARN 11:28:28,430 Small cdc volume detected at /cdc_raw; setting cdc_total_space_in_mb to 1982.
