I have mapped iscsi LUN, pvcreate, vgcreate and cannot see via GUI, I read taht is possible to condigure, but i cannot find how to?
I also found this article that talks about setting up ceph to use LVM manually outside of the Proxmox GUI/CLI. I was able to set up a OSD manually and it shows up in the GUI. I can even choose the Ceph RBD for creating a new hard drive in a VM, however, it failed at the end saying the ceph pool is locked. When I got time I might retry on a different node.Which part of the GUI are you referring to? I have set up a shared LVM storage type using iSCSI LUN without any issue. I don't see the LUN under the node's Disk section and I don't know why. But I can still add a LVM storage under Datacenter > Storage > Add (LVM). In the wizard, choose "Existing volume groups" for Base Storage, and the Volume group drop-down should show all available volume groups on the node.
The node's disk section seems to show local disks and FC LUNs only.
