Gluster users - May 2017 - Reasons for recommending nfs-ganesha

I currently use version 3.10.2.
When nfs is enabled, the following warning is displayed.
Why is nfs-ganesha recommended?
Is there something wrong with gluster nfs?

Gluster NFS is being deprecated in favor of NFS-Ganesha Enter "yes" to
continue using Gluster NFS (y/n)

The main reason behind above warning message is that currently most of 
the development focus
happens in NFS-Ganesha than gluster nfs(only bug fixes).
The following are major plus points for NFS-Ganesha
1.) NFS-Ganesha is a different community which supports a lot of other 
fIlesystem like CEPH(cephFS / RGW), GPFS, Lustre
2.) It support different nfs protocols including v3,v4, v4.1 and pNFS 
where as gluster NFS supports only v3
3.) Can do dynamic addition/modification of exports(shares) , where in 
gluster nfs each time server requires restart
4.)It has an integrated HA solution using pacemaker & corosync for 
gluster volumes

This is hardly new. The migration to NFS-Ganesha started with 3.8.0 and
there has been discussion about it on the Gluster community mailing
lists over the past two years.

gluster nfs (or gnfs) only supports NFSv3. The gnfs part doesn't have
High Availability (HA) out of the box. The design of gnfs doesn't lend
itself to adding NFSv4 and beyond.

NFS-Ganesha has NFSv3, NFSv4, NFSv4.1, NFSv4.2, pNFS ? and if you care
about it, 9P support. It's a better implementation, and it's being
actively developed and maintained.

Besides kernel NFS (knfs) it doesn't make sense to pay for maintaining
two very different NFS implementations. (IOW Red Hat isn't going to pay
to maintain and develop two different implementations. Someone else may
step up and maintain gnfs.)

You can keep using gnfs, but eventually you should switch to NFS-Ganesha
because that's where resources are devoted ? for fixing bugs and adding
features.

You *should* switch, but nobody is going to force you to switch. The
gnfs part will always be there and you'll always be able to use it.
