Hi all,

When I change resources like cpu and memory on limits ECK does nothing, the only way for me to have the sts to be update with my changes is to edit the sts manifest with kubectl edit for applying new values to the sts

Exemple

I want to add the following :

```auto
resources:
  requests:
    cpu: 2
    memory: 2Gi
  limits:
    cpu: 4
    memory: 4Gi

```

On the spec for podTemplate instead of

```auto
resources:
  limits:
    memory: 2Gi

```

Am I the only guy with this behaviour ?

Thanks by advance for your replies.

Regards  
Christophe

Could you:

- Provide the full Elasticsearch manifest, before and after the change.
- Get the current Elasticsearch `Status` subresource value with ` kubectl get es/quickstart -o jsonpath='{ .status }' -n my-namespace`
- [Check if there is any error in the operator logs](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-troubleshooting-methods.html#k8s-get-eck-logs)

Thanks

Hi Michael,

Here is the manifest used to create the cluster, you see here all the resources requested and limited but on the first try only memory limit have been set.

The result you wanted

> kubectl get elasticsearch -A

```auto
NAMESPACE NAME HEALTH NODES VERSION PHASE AGE

cdn-bigdata sophie-int green 19 8.6.0 Ready 24h

cdn-bigdata sophie-mon green 3 8.6.0 Ready 24h

```

> kubectl get es/sophie-int -o jsonpath='{ .status }' -n cdn-bigdata

```json
{
	"availableNodes": 19,
	"conditions": [{
		"lastTransitionTime": "2023-01-18T08:45:43Z",
		"status": "True",
		"type": "ReconciliationComplete"
	}, {
		"lastTransitionTime": "2023-01-17T13:08:36Z",
		"message": "All nodes are running version 8.6.0",

	}, {
		"lastTransitionTime": "2023-01-17T13:08:38Z",
		"message": "Cannot get compute and storage resources from Elasticsearch resource generation 2: cannot compute resources for NodeSet \"master\": memory request and limit do not have the same value",
		"status": "False",
		"type": "ResourcesAwareManagement"
	}],
	"health": "green",
	"inProgressOperations": {
		"downscale": {
			"lastUpdatedTime": "2023-01-17T13:08:36Z"
		},
		"upgrade": {
			"lastUpdatedTime": "2023-01-18T08:45:03Z"
		},
		"upscale": {
			"lastUpdatedTime": "2023-01-17T13:08:36Z"
		}
	},
	"monitoringAssociationStatus": {
		"cdn-bigdata/sophie-mon": "Established"
	},
	"observedGeneration": 2,
	"phase": "Ready",
	"version": "8.6.0"
}

```

Correct me if I’m wrong but why requests and limits need to be the same ? for me it’s a non-sense because requests and limits doesn’t have the same function.

(Attachment sophie-int-es.yaml is missing)

The status states that the resource is `Reconciled`. Either it is actually the case, or you applied a change but the operator is not (correctly) running. Could you please:

1. Provide the operator logs (see the command in my previous message)
2. Get a diff between the actual state and the expected state.

Also "applying new values to the sts" should not work as expected since there are controlled by the operator.

Regarding the memory requests and limits I would suggest to read this [documentation](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-managing-compute-resources.html).

HI Michael,

After a restart from scratch of the manifest all is working well and as expected. I think we can close this discussion 🙂
