fair enough.  I like the granularity and independence.  I have fewer than 20 resources/VMs.

I've no working experience with ZFS so I can't help you there. I'm pretty sure I've seen it discussed here though.  Have you gone through the archives?

    I create a large data drive out of a bunch of small SSDs using
    RAID and make that RAID drive an LVM PV.

    I can then create LVM volume groups and volumes for each use (in
    my case virtual drives for KVM) to back specific DRBD resources
    for each VM.  It allows me to have a DRBD resource for each VM,
    each backed by an LVM volume which is in turn on a large LVM PV.

    VM has DRBD resource as it's block device --> DRBD resources
    backed by LVM volume --> LVM volume on a large RAID based Physical
    Volume.

What I would like is to create an HA NFS storage, if possible with ZFS but without putting ZFS on top of DRBD (i prefere the opposite: DRBD on top of ZFS)
