I have a four node EC2 cluster. Three machines show via nodetool ring that all machines are UP. One machine shows via nodetool ring that one machine is DOWN.
If I take a closer to the machine reporting the other machine as down, I see the following: - StorageService.UnreachableNodes = 10.49.9.109 - FailureDetector.SimpleStates: 10.49.9.109 = UP So gossip is fine. Actually the whole 10.49.9.109 machine is fine. I see in the logging that there is communication between 10.49.9.109 and the machine reporting it as down. How or when is a node removed from the UnreachableNodes list and reported as UP again via nodetool ring? I use Cassandra 1.0.11 Thanks! Rene
