That's what NFS-Ganesha does. The gluster-fuse client works but is slower than most people like. I use the fuse process in my setup at work.

I had planned on using GlusterFS native NFS until I saw that it is being deprecated. Then, I was going to use GlusterFS + NFS-Ganesha until I saw that the Ganesha HA support ended after 3.10 and its replacement is still a WIP. So, I landed on GlusterFS + kernel NFS + corosync & pacemaker, which seems to work quite well. Are there any performance issues or other concerns with using GlusterFS as a replication layer and kernel NFS on top of that?</div><div><br></div><div>Thanks!</div></div>
