Dear Roland,

thank you for your response

This proxmox/drbd cluster exists since quite a while and was always 
upgraded as upgrades appeared for drbd, linstor and the linstor-proxmox 

Initially I tried adding a volume group for DfltRscGrp, but it
wouldn't work as I had already existing resource definitions for
the resource group DfltRscGrp.  Thus I had the idea to create a
new resource group and a corresponding volume group and then
to change the resource definitions to use the new resource group.
That worked for me.  Once empty, I was able to create a volume group
for the DfltRscGrp.  In principle I could now migrate the resource
definitions back.
