Hi all, has anyone worked on removing node from couchdb cluster?
I have a 5 node cluster 0,1,2,3,4
Q=2 and n=3
So some shard replicas are on node 3,4 which I want to decommission.
I want to know whether I have to move all shards from node 3,4 to node 0 1 or 2 - directory data/.shards and data/shards on node 3 and 4
or I can simply update shard map of databases to remove node 3,4 from change log , by_node, by_range and run force synchronisation. Will couch db take care of shard replication if I update the shard map
