Using Express to Onboard Cinder Nodes with Shared Storage Causes LVM Role Application

[eloyfm00]

Onboarding a cinder node which is intended to be used with shared storage backend using the pf9-express tool causes the LVM role to be applied instead by default as per the link below.

express/pf9-express.yml

Line 127 in ff4878b

- { role: "map-role", rolename: "pf9-cindervolume-lvm", when: autoreg == "on" }

I think this is expected. LVM is required for the iSCSI connection in order to leverage the shared storage path. Otherwise, you would need some other Cinder backend to support this.
