[DRBD-user] Issue creating storage volume with linstor-proxmox

Hello,

we are recently experiencing an issue which prevents us from creating
storage volumes for proxmox VMs using the linstor-proxmox plugin.
We had been able to create them in the past, but now it stopped working/
(We upgrade both proxmox and the linstor/drbd software regularly.)

It appears to relate to something with volumes:

Message: Could not create resource definition vm-101-disk-1 from resource 
group DfltRscGrp, because: 
[{"ret_code":-4611686018406154012,"message":"Invalid count of volume sizes 
to spawn resource group 'DfltRscGrp'","correction":"Either provide the correct 
count of volume sizes or use the 'partial' option","details":"The resource 
group 'DfltRscGrp' has 0 Volume groups, but only 1 sizes were provided.
....
[See below for the full message.]

The entry we have in /etc/pve/storage.cfg:

drbd: drbdstor-1
         content rootdir,images
         controller 10.0.7.32
         controllervm 100
         resourcegroup DfltRscGrp
         preferlocal yes
         nodes pmbase1,pmbase2

There is already a resource defined (done > 1 year ago):
+------------------------------------------------------------------------+
| ResourceName  | Node    | Port | Usage  | Conns |    State | CreatedOn |
|========================================================================|
| vm-100-disk-0 | pmbase1 | 7000 | Unused | Ok    | UpToDate |           |
| vm-100-disk-0 | pmbase2 | 7000 | InUse  | Ok    | UpToDate |           |
+------------------------------------------------------------------------+

Today, I deleted some VMs and their volumes and just wanted to create
new ones.

Software versions:

pve-manager/6.4-13/9f411e79 (running kernel: 5.4.140-1-pve)

linstor-client                       1.10.1-1
linstor-common                       1.14.0-1 
linstor-controller                   1.14.0-1 
linstor-proxmox                      5.2.1-1 
linstor-satellite                    1.14.0-1
python-linstor                       1.10.1-1

Please advise how we may correct the situation.

Thank you very much,

w.w.

Issue as it appears in syslog:
