[PVE-User] Is there any problem using DRBD over LVM?

[Gilles Mocellin]

Hello,

Not in a proxmox context, I also had to answer that question.

I used DRBD over LVM.
I think it's the easiest way to handle resizing. I didn't have to 
allocate a whole partition.
I can use only a small LV to begin, and resize if necessary after. Or 
create another LV for another DRBD volume...

Anyway, what would be difficult to handle is LVM over DRBR over LVM ! >:o
