I am running a 3 node cluster of 3.0.6 instances and encountered an error when running nodetool compact. I then ran nodetool repair. No errors were returned. I then attempted to run nodetool compact again, but received the same error so the repair made no correction and reported no errors. After that, I moved the problematic files out of the directory, restarted cassandra and attempted the repair again. The repair again completed without errors, however, no files were added to the directory that had contained the corrupt files. So nodetool repair does not seem to be making actual repairs. I started looking around and numerous directories have vastly different amounts of content across the 3 nodes. There are 3 replicas so I would expect to find similar amounts of content in the same data directory on the different nodes.
Is there any way to dig deeper into this? I don't want to be caught because replication/repair is silently failing. I noticed that there is always an "some repair failed" amongst the repair output but that is so completely unhelpful and has always been present. Thanks, Jason
