Need help with a large cluster restart


(search) #1

I have 20 ES data nodes and 10 master nodes in my cluster. I have 6 minimum
master nodes for the cluster to function. I wanted to know if any one knows
of a correct way to restart a large cluster. I see different results on
each cluster restart. Some times, some of the shards are in Unassigned
state and they are stuck in that state. Some times the shards are getting
re-allocated. So far, I am always doing a Full Cluster restart. All I want
to do is restart and come back to the state where it was before restart. I
really appreciate any insight into this or a link to a documentation about
the cluster restarts.

Thanks.
