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.
