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 `
2. Blacklist CSI-PowerFlex volumes in multipath config file | >*Note*: `vxflexos-controller-*` is the controller pod that acquires leader lease
