I am running a Proxmox 8.2.4 cluster of 3 nodes on 3 Dell 710 (repurposed GSA) servers. I have set up a GlusterFS volume using the local storage on each of the three nodes. I have gluster-server 11.1-1 installed. I am using a separate 1Gb Ethernet network for the gluster peers. (There are 4 NICs on each server, and I am using one NIC on a private network for gluster). I wan't to set up shared storage so that I can move VMs between the nodes. The RAID controllers on the servers will not allow me to pass-through the disks, so setting up Ceph is not an option.

I have the IP addresses for the Gluster NICs in the /etc/hosts file of each node. The peers, volume and GlusterFS storage for the cluster was set up using those hostnames.

Everything appears to be functioning. I moved the storage for one VM onto the GlusterFS storage using the qcow2 storage type and started the VM. I then tried to take snapshot of the VM. Immediately, the VM stopped running and the snapshot attempt failed because the VM was no longer active. I am able to start the VM again, but when I try to take a snapshot, the VM immediately crashes. I've not been unable to find anything in any of the logs to indicate what is failing.

I haven't been able to find anything indicating the version of Gluster that is compatible with Proxmox 8.2.4.

Is there some incompatibility that is making what I am attempting to do impossible? It is possible that I don't have Gluster configured properly?
