How did you then split up the DRBD volume between VMs? Did you configure 
a dedicated DRBD resource for each VM?

(or maybe "not in a proxmox context" means there were no VMs involved 
and you just used the whole volume for one application, in that case 
ignore these questions)

I once configured LVM over DRBR over LVM (on  Proxmox 1.x) and it worked 
pretty well, it's the most flexible solution allowing you to move or 
resize anything with little or no pain. However, eventually I got rid of 
it because it would have been a nightmare to maintain in case of 
problems, given the lack of sufficiently skilled Linux sysadmins besides 
myself.
