How should I use proxmox as a NAS with ZFS and GlusterFS?

[jvank]

Hi all,

I want to deploy 2 proxmox servers, with VMs running on one of them and the other being there for failover. I also want to use these machines as storage using ZFS. I want this storage to replicate between the two servers, for which I want to use something like GlusterFS.

Is it smarter to follow this guide completely or should I install ZFS and Gluster on the servers, then share them with samba from an LXC container?

Kind regards,

jvank

Thinking of doing the same.

You can also use ZFS with replication for failover. For important VMs you can use a replication interval of down to 1 minute.
If that is good enough for you it is definitely the simpler solution. https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_pvesr

Don't forget that you need at least a 3rd vote in the cluster for quorum. If you cannot add a third full node you can use a so-called QDevice. This is a service that can run on any other machine, even a raspberry pi works. See https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_corosync_external_vote_support for more infos.

I agree with @aaron that replication is the simpler solution for virtual machines.

If you want to use GlusterFS: I don't see a reason to use samba or containers. You can install Gluster directly on your Proxmox VE hosts and run a hyper-converged setup. To do so, you can follow the offical Gluster Quick Start Guide for Debian.

Hi,

I did some tests with GlusterFS and I noticed some performance issues.
