Hi, I re-post this here because it's a new subject far away from my initial tuning questions.
I wanted to try a new config. After doing a rolling restart I have all my counters false, with wrong values. I stopped my servers with the following : nodetool -h localhost disablegossip nodetool -h localhost disablethrift nodetool -h localhost drain kill cassandra sigterm (15) via htop And after restarting the second one I have lost all the consistency of my data. All my statistics since September are totally false now in production. As reminder I'm using a 2 node cluster RF=2, CL.ONE 1 - How to fix it ? (I have a backup from this morning, but I will lose all the data after this date if I restore this backup) 2 - What happened ? How to avoid it ? Any Idea would be greatly appreciated, I'm quite desperated. Alain
