Fixed Issues
Known Issues
| Issue | Workaround |
| Delete namespace that has PVCs and pods created with the driver. The External health monitor sidecar crashes as a result of this operation. | Deleting the namespace deletes the PVCs first and then removes the pods in the namespace. This brings a condition where pods exist without their PVCs and causes the external-health-monitor sidecar to crash. This is a known issue and has been reported at https://github.com/kubernetes-csi/external-health-monitor/issues/100 |
| When a node goes down, the block volumes attached to the node cannot be attached to another node | This is a known issue and has been reported at https://github.com/kubernetes-csi/external-attacher/issues/215. Workaround: 1. Force delete the pod running on the node that went down 2. Delete the volumeattachment to the node that went down. Now the volume can be attached to the new node. |
| sdc:3.6.0.6 is causing issues while installing the csi-powerflex driver on ubuntu,RHEL8.3 | Workaround: Change the powerflexSdc to sdc:3.6 in values.yaml https://github.com/dell/csi-powerflex/blob/72b27acee7553006cc09df97f85405f58478d2e4/helm/csi-vxflexos/values.yaml#L13 |
Note:
- 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.

Known Issues
| Issue | Workaround |
| Unable to update Host: A problem occurred modifying the host resource | This issue occurs when the nodes do not have unique hostnames or when an IP address/FQDN with same sub-domains are used as hostnames. The workaround is to use unique hostnames or FQDN with unique sub-domains |
| When a node goes down, the block volumes attached to the node cannot be attached to another node | This is a known issue and has been reported at https://github.com/kubernetes-csi/external-attacher/issues/215.

Known Issues
| Issue | Resolution or workaround, if known |
| If the length of the nodeID exceeds 128 characters, the driver fails to update the CSINode object and installation fails. This is due to a limitation set by CSI spec which doesn’t allow nodeID to be greater than 128 characters. | The CSI PowerScale driver uses the hostname for building the nodeID which is set in the CSINode resource object, hence we recommend not having very long hostnames in order to avoid this issue. This current limitation of 128 characters is likely to be relaxed in future Kubernetes versions as per this issue in the community: https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/issues/581 Note: In kubernetes 1.22 this limit has been relaxed to 192 characters. |
| If some older NFS exports /terminated worker nodes still in NFS export client list, CSI driver tries to add a new worker node it fails (For RWX volume). | User need to manually clean the export client list from old entries to make successful addition of new worker nodes. |
| Delete namespace that has PVCs and pods created with the driver. The External health monitor sidecar crashes as a result of this operation. | Deleting the namespace deletes the PVCs first and then removes the pods in the namespace. This brings a condition where pods exist without their PVCs and causes the external-health-monitor sidecar to crash. This is a known issue and has been reported at https://github.com/kubernetes-csi/external-health-monitor/issues/100 |
| fsGroupPolicy may not work as expected without root privileges for NFS only https://github.com/kubernetes/examples/issues/260 | To get the desired behavior set “RootClientEnabled” = “true” in the storage class parameter |
| Driver logs shows “VendorVersion=2.3.0+dirty” | Update the driver to csi-powerscale 2.4.0 |
Note:
- 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.

Fixed Issues
Known Issues
| Issue | Workaround |
| Topology-related node labels are not removed automatically. | Currently, when the driver is uninstalled, topology-related node labels are not getting removed automatically. There is an open issue in the Kubernetes to fix this. Until the fix is released, remove the labels manually after the driver un-installation using command kubectl label node <node_name> – – … Example: kubectl label node csi-unity.dellemc.com/array123-iscsi- Note: there must be – at the end of each label to remove it. |
| NFS Clone – Resize of the snapshot is not supported by Unity XT Platform, however the user should never try to resize the cloned NFS volume. | Currently, when the driver takes a clone of NFS volume, it succeeds but if the user tries to resize the NFS volumesnapshot, the driver will throw an error. |
