I think that DRBD9 with LINSTOR for its management interface, might also be an alternative option for your setup.
It can use either LVM or ZFS as its storage backend, but however it operates at the block level. Not sure if that would be a problem for you?
Apart of that, it supports snapshots, clones etc..

Subject: [PVE-User] Find the right storage for my needs
Dear PVE users,
I'm looking for a storage back-end that will fits my scenario. Let me
explain my actual setup:
3 nodes cluster: 2 nodes have 2*3TB disks used with GlusterFS replica
(there is also a raspberry doing arbitrator), running several VM and
The 2*3TB disks are pvs of an LVM structure, 'cause it's a home server
and I'm pretty happy with the GlusterFS redundancy, giving me a 6TB
The third node just run a VM with FreeNAS that share a NFS storage to
the cluster, where i do my backups and store isos and templates.
The GlusterFS is mounted at OS level (fstab) and PVE see it as Directory
(otherwise I cannot run LXC over it).
It works fine, I'm happy about performance and I also can migrate vms
and containers between nodes.
All nodes are connected to the GlusterFS network with a bond interface
of 2 gigabit nics.
My problem is that backups are very slow for LXC, because, I suppose, it
cannot use snapshots.
So, I'm looking for a storage back-end that:
- is replicated across two nodes (I can use the third node as
- don't loose disk space (I want to have a shared storage of more or
- can work with LVM structure, because I also have SSD caching that I
want to preserve
- can be used as shared storage
- can do snapshots of LXC to speed-up the backup process
If it's possibile, I prefer to use PVE integrated solution (like Ceph or
ZFS), but I'm open to all other solutions.
Thanks a lot and best regards
