I did (quite) a bit more research on what is happening here.  The 
peer-disks here that are listed as Diskless, are a result of me adding 
--diskless-on-remaining for the resource-group, and are not a result of 
the proxmox plugin.  I can also see the created resources via linstor 
volume list, and the diskless volumes are indeed part of 
"DfltDisklessStorPool".  Without that option, resourced created only 
show up in tank1's device tree.  So, I can say with confidence now, that 
it's the proxmox plugin that is not behaving as it should, or I have it 
configured incorrectly, as no matter what I do, the storage node only 
appears on tank1 properly, tank2 and tank3 show question marks, and I 
cannot see any drbd resources within, nor get stats. How can I debug the 
plugin further?   Thanks in advance for any assistance that anyone can 
provide.
