hi  
sorry if there is another way to bumb expired topics/comments  
Was there a solution to this dialogue ?

> ES Version 5.6.2 For the past few weeks, every time I check ES Monitoring, twenty shards are being reallocated: [image] This is defined as the max in my cluster settings. I have it set higher than default as many of the machines I'm running on are random servers and not the most reliable. Hence if a node fails I want the cluster to dynamically reallocate shards. However no nodes have gone down in the past few weeks... GET \_cluster/settings { "persistent": { "cluster": { "routing…

Thanks!

(sorry for the irrelevant tag, the preset options arent applicable)

Which version are you having this issue? I suggest you open a new topic or search for one similar for a more recently version.

The version linked in the post is pretty old.

Did you change the allocation settings?

More specifically these two:

`cluster.routing.allocation.cluster_concurrent_rebalance`  
`cluster.routing.allocation.node_concurrent_recoveries`

There is an open issue about it, you can check it [here](https://github.com/elastic/elasticsearch/issues/87279).

hi again,  
so i found this in my search, looks like the scenario is different though: no upgrade or high watermark issues in my use case:

> [@Cluster shards unbalanced and keep moving shards around after upgrade to 8.8.1](https://discuss.elastic.co/t/cluster-shards-unbalanced-and-keep-moving-shards-around-after-upgrade-to-8-8-1/336573/17):
>
> Hello @DavidTurner, There was another issue, a couple of the nodes were hitting the watermarks and others were close to it, so probably any shard movement could trigger another watermark that would then trigger another shard movement. I removed some old data to make sure that no node in the warm tier would hit any watermark, and after sometime there are no more shard movements. $ cat desired-balance.json | grep "node\_is\_desired" | grep -v relocating | grep false | wc -l 0

Is there a post somewhere you can reference ?

Use `GET _cluster/settings` to check it.

This is still an open issue, the post you shared, that I opened when I had a similar issue has some discussion about it and the github issue linked has some information as well.

#!/bin/bash

curl -s http://localhost:9200/_cluster/settings | jq . 
[Thu Mar 07 15:37:33] root@server.ebo:~# settings.sh 
{
  "persistent": {},
  "transient": {
    "cluster": {
      "routing": {
        "allocation": {
          "exclude": {
            "_name": "stuff and stuff"
          }
        }
      }
