| If the volume limit is exhausted and there are pending pods and PVCs due to `exceed max volume count`, the pending PVCs will be bound to PVs and the pending pods will be scheduled to nodes when the driver pods are restarted. | It is advised not to have any pending pods or PVCs once the volume limit per node is exhausted on a CSI Driver. There is an open issue reported with kubenetes at https://github.com/kubernetes/kubernetes/issues/95911 with the same behavior. |
| The PowerFlex Dockerfile is incorrectly labeling the version as 2.7.0 for the 2.8.0 version. | Describe the driver pod using ```kubectl describe pod $podname -n vxflexos``` to ensure v2.8.0 is installed. |
| Resource quotas may not work properly with the CSI PowerFlex driver. PowerFlex is only able to assign storage in 8Gi chunks, so if a create volume call is made with a size not divisible by 8Gi, CSI-PowerFlex will round up to the next 8Gi boundary when it provisions storage -- however, the resource quota will not record this size but rather the original size in the create request. This means that, for example, if a 10Gi resource quota is set, and a user provisions 10 1Gi PVCs, 80Gi of storage will actually be allocated, which is well over the amount specified in the resource quota. | For now, users should only provision volumes in 8Gi-divisible chunks if they want to use resource quotas. |
| Helm install of CSM for PowerFlex v1.10.0 is failing due to a duplicate `mountPath: /host_opt_emc_path` being added to volumeMounts charts/csi-vxflexos/templates/node.yaml. Error message is `Error: INSTALLATION FAILED: 1 error occurred: DaemonSet.apps "vxflexos-node" is invalid: spec.template.spec.initContainers[0].volumeMounts[4].mountPath: Invalid value: "/host_opt_emc_path": must be unique` | The issue can be resolved by removing the duplicate entry in [https://github.com/dell/helm-charts/blob/main/charts/csi-vxflexos/templates/node.yaml](https://github.com/dell/helm-charts/blob/main/charts/csi-vxflexos/templates/node.yaml) |


### Note:

- Support for Kubernetes alpha features like Volume Health Monitoring will not be available in Openshift environment as Openshift doesn't support enabling of alpha features for Production Grade clusters.
- Support for Kubernetes alpha features like Volume Health Monitoring and RWOP (ReadWriteOncePod) access mode will not be available in Openshift environment as Openshift doesn't support enabling of alpha features for Production Grade clusters.
- For fixing [#1210 - [BUG]: Helm deployment of PowerFlex driver is failing](https://github.com/dell/csm/issues/1210), a new helm-chart has been released. In order to install this helm chart, we need to pass the flag `--helm-charts-version` during helm installation and flag `-v` during offline bundle installation with value `csi-vxflexos-2.10.1`.
