CouchBase 2.5副本中的2个节点：1个节点失败：该服务不再可用

Question

We are testing Couchbase with a two node cluster with one replica.

When we stop the service on one node, the other one does not respond until we restart the service or manually failover the stopped node.

Is there a way to maintain the service from the good node when one node is temporary unavailable?

Answer 1

If a node goes down then in order to activate the replicas on the other node you will need to manually fail it over. If you want this to happen automatically then you can enable auto-failover, but in order to use that feature I'm pretty sure you must have at least a three node cluster. When you want to add the failed node back then you can just re-add it to the cluster and rebalance.
