The "Operations" page has been changed by jeremyhanna. The comment on this change is: Removed unnecessary ! character (since it preceeded two capital letters). http://wiki.apache.org/cassandra/Operations?action=diff&rev1=48&rev2=49 -------------------------------------------------- 1. Anti-Entropy: when `nodetool repair` is run, Cassandra performs a major compaction, computes a Merkle Tree of the data on that node, and compares it with the versions on other replicas, to catch any out of sync data that hasn't been read recently. This is intended to be run infrequently (e.g., weekly) since major compaction is relatively expensive. === Handling failure === - If a node goes down and comes back up, the ordinary repair mechanisms will be adequate to deal with any inconsistent data. Remember though that if a node is down longer than your configured !GCGraceSeconds (default: 10 days), it could have missed remove operations permanently. Unless your application performs no removes, you should wipe its data directory, re-bootstrap it, and removetoken its old entry in ghe ring (see below). + If a node goes down and comes back up, the ordinary repair mechanisms will be adequate to deal with any inconsistent data.

If a node goes down entirely, then you have two options:
