[Gluster-users] Latest NFS-Ganesha Gluster Integration docs

[wkmail at bneit.com]

For many years, we have maintained a number of standalone, 
hyperconverged Gluster/Libvirt clusters  Replica 2 + Arbiter using Fuse 
mount and Sharding.

Performance has been mostly acceptable. The clusters have high 
availability and we have had very zero problems over the years as long 
as we do green field upgrades to new major versions.

So that is the beauty of Gluster in our opinion. It is easy to setup and 
use and it simply works without much thought.

As we ask more of our VMs, we see that disk i/o sometimes is a 
bottleneck and I am looking at improving things.

On this list I keep on seeing comments that VM performance is better on 
NFS and a general dissatisfaction with Fuse. So we are looking to see 
for ourselves if NFS would be an improvement.

We looked into gfapi but our hosts are mostly Ubuntu and gfapi is not 
built in. We would prefer to stay with stock components for the critical 
underbelly of the infrastructure.

So in looking into NFS,  I find instructions for NFS-Ganesha as a 
standalone, and I see mentions of Gluster Drivers but then I see 
mentions of StorHaug which sort of seems to be worked on. I also see 
pacemaker type failover instructions.

Is there a set of instructions for replacing our Fuse Mount setup with 
NFS/Ganesha and how HA is achieved  (with or without StorHaug).

Any advice in this area would be appreciated.
