.marvel-kibana has an unassigned primary. How to fix this?

Elastic Stack Elasticsearch
1

Hi,

I have a 3-node Elasticsearch cluster. When I perform a rolling restart on the cluster, once the restart is completed, the Elasticsearch cluster status is coming as red. Even with multiple restarts I am unable to bring the cluster state to even yellow.

On checking with the Marvel plugin installed on all 3 of my Elasticsearch nodes, hovering over the i symbol next to the cluster status its showing this error:

.marvel-kibana has an unassigned primary

This problem is coming only for the .marvel-kibana index, the other indices there is no issue.

I am doing the following when doing the rolling restart:

  1. Disabling shard allocation on all nodes.
  2. Stopping Elasticsearch on all nodes by killing the running Elasticsearch process (I'm not running ES as a service, I'm starting it via a script).
  3. Starting Elasticsearch on the primary master node first via a script.
  4. Starting Elasticsearch on the other nodes.
  5. Enabling shard allocation on all nodes.

I checked the logs also, all nodes are joining the cluster after starting Elasticsearch on them. I can't forcibly reroute the shards, it would delete the data from the index.

I am unable to find a permanent solution to the problem even after 1 week of debugging. How to fix this issue?
