So far so good, would have done the same.

Where and how do you see that?

The Proxmox plugin never creates multi-volume resources. Every disk is a
new, single-volume, DRBD resource. If not, the plugin has a bug.

If "resource create" created a second volume, which is hard to believe,
LINSTOR has a bug.

So please post the res file of that resource (in /var/lib/linstor.d/).
And also the "drbdsetup status vm-108-disk-1"

If there are really two volumes (with one DRBD resource), any ideas how
the second was created? Your are not mixing terms here?
