Too many shards?

Elastic Stack Elasticsearch
1

Hello

We are having unhealthy deployment, I tried to check the shards state, it seems we have too many shards ?? /_cat/shards?h=index,shard,prirep,state,unassigned.reason

The head size we have:

"jvm": {
        "mem": {
          "non_heap_used_in_bytes": 228968704,
          "heap_max_in_bytes": 30887378944,
          "heap_used_in_bytes": 4712939208,
          "heap_committed_in_bytes": 30887378944,
          "heap_used_percent": 15,
          "non_heap_committed_in_bytes": 247660544,
          "pools": {
            "old": {
              "max_in_bytes": 30023680000,
              "peak_max_in_bytes": 30023680000,
              "peak_used_in_bytes": 4063783088,
              "used_in_bytes": 4063783088
            },
            "young": {
              "max_in_bytes": 767754240,
              "peak_max_in_bytes": 767754240,
              "peak_used_in_bytes": 767754240,
              "used_in_bytes": 632512272
            },
            "survivor": {
              "max_in_bytes": 95944704,
              "peak_max_in_bytes": 95944704,
              "peak_used_in_bytes": 95944704,
              "used_in_bytes": 16643848
            }
          }
        },

And for /_cluster/allocation/explain?pretty

Any support would be highly appreciated.

Can you share the output of those two api's?
Also What is the cluster state ?

3

The output from the _cluster/stats?pretty&human API would be better please.

Thanks for getting back to me on this.
Just click on the api's I mentioned above, its linked to the output in a GitHub gist page.

I have got the stats after we have restarted the deployment, click _cluster/stats?pretty&human to view the output please.

the current stats look good, also you just have 191 shards , so that's all right .
Do you see any issues now?

6.8 reached EOL this month, you should definitely consider upgrading given we've just released 8.0 :slight_smile:

That aside, your cluster is green, so it's not clear why you think this is unhealthy?

7

After restating the deployment, it got green. Thanks for the note regarding 6.8.x reaching EOL, is there any recommended upgrade approach?
