[Gluster-users] GlusterFS in comparison with NFSv4

[Kevin Lemonnier]

Hi,

Depending on what you plan to do on it, might be better to use
NFS to mount the volume rather than the gluster fuse client.
Did you try this ? You can usually mount it with something like this :

mount -t nfs gluster-node.com:/volume_name /mnt/mountpoint
