LVM Group Removal Bug?

I have one ProxMox host running with no VMs active.

Through the Datacenter | Storage Tab, I added an iSCSI target with no problems. It now appears in the storage list.

Then I created an LVM group (eg VG001) using my iSCSI lun as base. So far so good. It too appears in the storage list.

Then I remove the LVM group. It disappears from the storage list.

Then I try to create another LVM group (eg VG002) using the same iSCSI base device.

The dialog reports an error - that the original LVM (VG001) is still assigned to the iSCSI device.

When I shell into the Proxmox host, vgdisplay shows that group VG001 still exists.

I remove VG001 using vgremove.

Then back in the GUI, I try to create a new LVM group on the same iSCSI lun, and it works!

Please advise if I am doing something wrong.

Thanks in advance.
