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. | - +| CSI driver does not verify iSCSI initiators on the array correctly when iSCSI initiator names are not in lowercase - After any node reboot, the driver pod on that rebooted node goes into a failed state, failing to find the iSCSI initiator on the array | Work around is to rename host iSCSI initiators to lowercase and reboot the respective worker node. The CSI driver pod will spin off successfully. Example: Rename "iqn.2000-11.com.DEMOWORKERNODE01:1a234b56cd78" to "iqn.2000-11.com.demoworkernode01:1a234b56cd78" in lowercase. ### 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.
