Check your /etc/ drbdmanaged.cfg file and make sure that the storage type
defined  there, is configured properly.
Is it thin or thick LVM? If it's thin LVM how did you create it ?


- The control volume is happy and connected to the other nodes?

Yes, control volumes seem to be OK and drbd nodes too, but that's unrelated
to the storage which you have dedicated to DRBD (/etc/drbdmanaged.cfg). You
need to make sure that, that one is also OK.

Before adding/removing VMs based on DRBD storage, you have to make sure
that DRBD storage works first. This means you need to check drbd pool
status, and use   drbdmanage add-resource, drbdmanage add-volume commands
in CLI to add/remove DRBD volumes. If that does not work, then proxmox gui
will not work as well.
