I am using couchbase 5.1 enterprise and using the default indexer setting for num_replica = 2.
Considering this, if an index node fails over and is subsequently recovered, what needs to be done to bring all index replicas on that node back online?
In my observation,
- I am seeing that only some of indexes replicas came back online on failed node.
- Four indexes were completely lost from all nodes.
I referred the documentation that says here
“Once an index has been created with a given number of replicas, if the number of index nodes in a cluster goes below the number of nodes required then new replicas will be created on any incoming index nodes, until the desired number of replicas exist for a given index.”
Is there anything additional I need to do in the event of a node failover or should things just come back up as they were prior to failover.
