If you check your data directory, does it contain a lot of "*Compacted" files? It sounds like you're churning sstables from a combination of compactions/flushes (including triggered by repair) and the old ones aren't being deleted. I wonder if there is still some issue causing sstable retention Since you're on 0.8.4, I'm a bit suspicious. I'd have to re-check each JIRA but I think the major known repair problems should be fixed except for CASSANDRA-2280 which is not your problem since you're going form a total load of 40 gig to hundreds of gigs (so even with all cf:s streaming, that's unexpected). Do you have any old left-over streams active on the nodes? "nodetool netstats". If there are "stuck" streams, they might be causing sstable retention beyond what you'd expect. -- / Peter Schuller (@scode on twitter)
