lvm volumes are not visible on the host machine.

[pawanpraka1]

When volume gets provisioned, the lvdisplay on the host does not show the volume. How ever the lvdisplay is showing the volume inside the lvm node daemonset.

inside container

$ kubectl exec -it openebs-lvm-node-cptgb -c openebs-lvm-plugin -n kube-system sh

@praveengt can you take a look at this one.

we can refresh the cache on the host to check all the lvm volumes on the node.

$ pvscan --cache
