Hi,
I solved the XFS issue for GlusterFS and NFS here: http://forum.proxmox.com/threads/17462-SOLVED-Linux-NFS-or-GlusterFS-Server-not-creating-sparse-files?highlight=nfs+glusterfs

Changing it to ext4 solved the main problem.
Another issue, even with ext4, was the timing when in the gluster cluster (2 nodes), there were one node down. There is a bug on gfapi that times out the proxmox cluster when trying to start a VM on that gluster storage.
While gluster developers fix that bug. I lowered the value on /proc/sys/net/ipv4/tcp_syn_retries from 5 to 3 to reduce the time necessary to start the VM and now everything works,

Hello Angel,Yes, I did. The main problem was the underlying filesystem. I do not know why, but XFS does not thin provision the space of the hard disk when create the virtual machine. Then proxmox times out at 30 seconds, or so. Because it should be matter of one or two seconds.
Did you figure it out why you had timeout problem ?

There is no special topology between the nodes, it's a 10Gb dedicated segment only for that purpose.
To mount glusterfs into PVE you can follow this tutorial
http://www.jamescoyle.net/how-to/533-glusterfs-storage-mount-in-proxmox
That is the proxmox way, and it's supposed to not to use FUSE, but to use the gluster translator (correct me if I'm wrong) and therefore no mount options are needed.
