Hi, I have a 5 server cluster running 1 collection with 20 shards, replication factor of 2.
Earlier this week I had to do a rolling restart across the cluster, this worked great and the cluster stayed up the whole time. The problem is that the last node I restarted is now the leader of 0 shards, and is just holding replicas. I've noticed this node has abnormally high load average, while the other nodes (who have the same number of shards, but more leaders on average) are fine. First, I'm wondering if that loud could be related to being a 5x replica and 0x leader? Second, I was wondering if I could somehow flag single shards to re-elect a leader (or force a leader) so that I could more evenly distribute how many leader shards each physical server has running? Thanks.
