PowerFlex
| Symptoms | Prevention, Resolution or Workaround |
|---|---|
The installation fails with the following error message: Node xxx does not have the SDC installed |
Install the PowerFlex SDC on listed nodes. The SDC must be installed on all the nodes that need to pull an image of the driver. |
When you run the command kubectl describe pods vxflexos-controller-* –n vxflexos, the system indicates that the driver image could not be loaded. |
- If on Kubernetes, edit the daemon.json file found in the registry location and add { "insecure-registries" :[ "hostname.cloudapp.net:5000" ] }- If on OpenShift, run the command oc edit image.config.openshift.io/cluster and add registries to yaml file that is displayed when you run the command. |
The kubectl logs -n vxflexos vxflexos-controller-* driver logs show that the driver is not authenticated. |
Check the username, password, and the gateway IP address for the PowerFlex system. |
The kubectl logs vxflexos-controller-* -n vxflexos driver logs show that the system ID is incorrect. |
Use the get_vxflexos_info.sh to find the correct system ID. |
The kubectl logs vxflexos-controller-* -n vxflexos driver logs show that the system ID is incorrect. |
Use the get_vxflexos_info.sh to find the correct system ID. Add the system ID to myvalues.yaml script. |
| CreateVolume error System |
Powerflex name if used for systemID in StorageClass ensure same name is also used in array config systemID |
| Defcontext mount option seems to be ignored, volumes still are not being labeled correctly. | Ensure SElinux is enabled on a worker node, and ensure your container run time manager is properly configured to be utilized with SElinux. |
| Mount options that interact with SElinux are not working (like defcontext). | Check that your container orchestrator is properly configured to work with SElinux. |
Installation of the driver on Kubernetes v1.21/v1.22/v1.23 fails with the following error: Error: unable to build kubernetes objects from release manifest: unable to recognize "": no matches for kind "VolumeSnapshotClass" in version "snapshot.storage.k8s.io/v1" |
Kubernetes v1.21/v1.22/v1.23 requires v1 version of snapshot CRDs to be created in cluster, see the Volume Snapshot Requirements |
The kubectl logs -n vxflexos vxflexos-controller-* driver logs show x509: certificate signed by unknown authority |
A self assigned certificate is used for PowerFlex array. See certificate validation for PowerFlex Gateway |
When you run the command kubectl apply -f snapclass-v1.yaml, you get the error error: unable to recognize "snapclass-v1.yaml": no matches for kind "VolumeSnapshotClass" in version "snapshot.storage.k8s.io/v1" |
Check to make sure that the v1 snapshotter CRDs are installed, and not the v1beta1 CRDs, which are no longer supported. |
The controller pod is stuck and producing errors such as" Failed to watch *v1.VolumeSnapshotContent: failed to list *v1.VolumeSnapshotContent: the server could not find the requested resource (get volumesnapshotcontents.snapshot.storage.k8s.io) |
Make sure that v1 snapshotter CRDs and v1 snapclass are installed, and not v1beta1, which is no longer supported. |
Driver install or upgrade fails because of an incompatible Kubernetes version, even though the version seems to be within the range of compatibility. For example: Error: UPGRADE FAILED: chart requires kubeVersion: >= 1.21.0 <= 1.23.0 which is incompatible with Kubernetes V1.21.11-mirantis-1 |
If you are using an extended Kubernetes version, please see the helm Chart at helm/csi-vxflexos/Chart.yaml and use the alternate kubeVersion check that is provided in the comments. Please note that this is not meant to be used to enable the use of pre-release alpha and beta versions, which is not supported. |
| Volume metrics are missing | Enable Volume Health Monitoring |
| 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. |
| CSI-PowerFlex volumes cannot mount; are being recognized as multipath devices | CSI-PowerFlex does not support multipath; to fix: 1. Remove any multipath mapping involving a powerflex volume with multipath -f <powerflex volume> 2. Blacklist CSI-PowerFlex volumes in multipath config file |
