One last tidbit, drbdadm status shows this for the resource I created in 
proxmox from tank1 without the diskless storage-pools created, and it is 
only showing up on tank1, not tank2 or tank3:

vm-3000-disk-1 role:Primary
   disk:UpToDate
   tank2 role:Secondary
*    peer-disk:Diskless*
   tank3 role:Secondary
*    peer-disk:Diskless*

Not sure what to make of that.  I am hesitant to blame the proxmox 
plugin here, as I don't even see the devices listed in /dev on 2 and 3.
