Alain, We performed a 1.1.3 -> 1.1.6 upgrade and found that all the logs replayed regardless of the drain. After noticing this on the first node, we did the following:
* nodetool flush * nodetool drain * service cassandra stop * mv /path/to/logs/*.log /backup/ * apt-get install cassandra <restarts automatically> I also agree that starting C* after an upgrade/install seems quite broken if it was already stopped before the install. However annoying, I have found this to be the default for most Ubuntu daemon packages.
