Yes, I regard qemu -> DRBD -> volume management [-> RAID] -> disk the
most recommendable solution for this scenario.
I personally go with LVM thinp for volume management, but ZVOLs should
do the trick, too.
With named ressources (named after VMs)

Hello,
Personally I'm using option (a) on a 3 node proxmox cluster and drbd9.
Replica count per VM is 2 and all 3 nodes act as both drbd control volumes
and satellite nodes.I can live migrate VM between all nodes and snapshot
them by using drbdmanage utility (which is using zfs snapshot+clones).

having one DRBD ressource per VM also allows you to run VMs on both
hosts

Hi, I plan to use a primary/secondary setup, with manual failover.
In other words, split brain should not be possible at all.
Thanks.
