Can somebody suggest solution to resolve this issue ?
Status of the cluster is RED.
Which version of Elasticsearch are you using?
Have you brought back the node that left?
How many nodes do you have in the cluster? Hoiw is it configured?
Do you have replica shards configured for your indices?
Elasticsearch version : 7.16.3
Yes node is back to cluster
10 nodes 1 master
not sure about if replica shards are configured or not , could you please help me checking in that?
