We use Cassandra 2.0.8. Probably after decommissioning nodes long time ago, but I am not sure. We are not using this cluster intensively.
According to Jira, this problem was fixed in 2.0.5 https://issues.apache.org/jira/browse/CASSANDRA-6053 Anyway, I truncated peers table and restarted one node to repopulate it. The problem has gone, but I have a question. Why peers table contains only 2 out of 3 nodes? *nodetool status* results in: UN 10.4.116.127 14.01 GB 256 32.6% ee89e721-176e-4a82-ae94-32c77295aa1b rack1 UN 10.4.116.126 13.33 GB 256 31.9% f9c088c9-ad55-412b-ad04-540332a0b3b2 rack1 UN 10.4.116.148 15.23 GB 256 35.5% f47c70b6-46bb-455e-b984-6384c939558d rack1 *select peer from system.peers;* results in: peer -------------- 10.4.116.127 10.4.116.126 Thanks, Pavel
