Yep, I noticed a couple of pages including this for 'storhaug

help alot:

https://www.spinics.net/lists/gluster-users/msg33018.html

Hence the ask here.  storhaug feels like it's not moving with any sort 
of update now.

Any plans to move back to the previous NFS Ganesha HA model with 
upcoming GlusterFS versions as a result?

In the meantime I'll look to cobble up the GlusterFS 3.10 packages and 
try with those per your suggestion.

What's your thoughts on using HAPROXY / keepalived w/ NFS Ganesha and 
GlusterFS?  Anyone tried this sort of combination?  I want to avoid the 
situation where I have to remount clients as a result of a node failing. 
  In other words, avoid this situation:

[root at yes01 ~]# cd /n
-bash: cd: /n: Stale file handle
[root at yes01 ~]#

Cheers,
Tom
