Latest NFS-Ganesha Gluster Integration docs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
