See events in kubectl -n rook-ceph describe pod rook-ceph-osd-prepare-* after the pod(s) got stuck.
Expected behavior
The pods rook-ceph-osd-prepare-* should disappear after a short time, and instead corresponding rook-ceph-osd-* pods (without -prepare-) should remain.
Additional context
I was using VKE with Kubernetes 1.23.x.

do you plan to support volumeMode: Block in the future?
is it possible to support volumeMode: Block by changing this CSI implementation?
Unofficially: I'd expect this should be possible (with changes). When attaching block devices to vultr instances normally, you get the raw device and can do stuff to them (create LVM volumes, basic filesystems, use LUKS, etc).
Describe the bug
Using rook.io, the rook pods
rook-ceph-osd-prepare-
fails to setup a PersistentVolumeClaim."describe pod" finally reports the event (warning) "MapVolume.SetUpDevice failed for volume "pvc-c869a0057b0c4904" : kubernetes.io/csi: blockMapper.stageVolumeForBlock failed to check STAGE_UNSTAGE_VOLUME capability: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial unix /var/lib/kubelet/plugins/block.csi.vultr.com/csi.sock: connect: connection refused"" from the kubelet.
To Reproduce
Steps to reproduce the behavior:
(NOTE: This setup works fine on Azure AKS, with only the storageClassName adjusted.)
kubectl -n rook-ceph describe pod rook-ceph-osd-prepare-*
after the pod(s) got stuck.Expected behavior
The pods
rook-ceph-osd-prepare-*
should disappear after a short time, and instead correspondingrook-ceph-osd-*
pods (without-prepare-
) should remain.Additional context
