<p class="MsoNormal" style="margin-left:36.0pt">I'm designing a 2-node, HA NAS that must support NFS. 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?<o:p></o:p></p>
