Hello,

If you use drbd over lvm (thick), I think it's possible with pvmove.

Assume sdb is hdd and sdc is ssd, all in the drbd volume group.
When you create a VM with proxmox, you can move the logical
volume (vm-100-disk-1 for example) for every cluster node with:

pvmove -n vm-100-disk-1 /dev/sdb1 /dev/sdc1
