Hey Guy's,
A success story instead of a question.
With your help, managed to get the HA component working with HAPROXY and
keepalived to build a fairly resilient NFS v4 VM cluster. ( Used
Gluster, NFS Ganesha v2.60, HAPROXY, keepalived w/ selinux enabled )
If someone needs or it could help your work, please PM me for the
written up post or I could just post here if the lists allow it.
Cheers,
Tom

Sounds good and no problem at all. Will look out for this update in the
future. In the meantime, three's a few things I'll try including your
suggestion.
Was looking for a sense of direction with the projects and now you've
given that. Ty. Appreciated!
Cheers,
Tom

Yep, I noticed a couple of pages including this for 'storhaug
configuration' off google. Adding 'mailing list' to the search didn't
help alot:
https://sourceforge.net/p/nfs-ganesha/mailman/message/35929089/
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?
No.
(re)writing or finishing storhaug has been on my plate ever since the
guy who was supposed to do it didn't.
I have lots of other stuff to do too. All I can say is it'll get done
when it gets done.
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@yes01 ~]# cd /n
-bash: cd: /n: Stale file handle
[root@yes01 ~]#
Cheers,
Tom

+ gluster users as well. Just read another post on the mailing lists
about a similar ask from Nov which didn't really have a clear answer.
That's funny because I've answered questions like this several times.
Gluster+Ganesha+Pacemaker-based HA is available up to GlusterFS 3.10.x.
If you need HA, that is one "out of the box" option.
There's support for using CTDB in Samba for Ganesha HA, and people have
used it successfully with Gluster+Ganesha.
Perhaps there's a way to get NFSv4 work with GlusterFS without NFS
Ganesha then?
Not that I'm aware of.

Hey All,
I've setup GlusterFS on two virtuals and enabled NFS Ganesha on each
node. ATM the configs are identical between the two NFS Ganesha
hosts. (Probably shouldn't be but I'm just testing things out.)
I need HA capability and notice these instructions here:
http://aravindavkgluster.readthedocs.io/en/latest/Administrator%20Guide/Configuring%20HA%20NFS%20Server/
However I don't have package glusterfs-ganesha available on this
CentOS Linux release 7.4.1708 (Core) and the maintainer's of CentOS 7
haven't uploaded some of the 2.5.x packages yet so I can't use that
version.
glusterfs-api-3.12.6-1.el7.x86_64
glusterfs-libs-3.12.6-1.el7.x86_64
glusterfs-3.12.6-1.el7.x86_64
glusterfs-fuse-3.12.6-1.el7.x86_64
glusterfs-server-3.12.6-1.el7.x86_64
python2-glusterfs-api-1.1-1.el7.noarch
glusterfs-client-xlators-3.12.6-1.el7.x86_64
glusterfs-cli-3.12.6-1.el7.x86_64
nfs-ganesha-xfs-2.3.2-1.el7.x86_64
nfs-ganesha-vfs-2.3.2-1.el7.x86_64
nfs-ganesha-2.3.2-1.el7.x86_64
nfs-ganesha-gluster-2.3.2-1.el7.x86_64
The only high availability packages are the following but they don't
come with any instructions that I can find:
storhaug.noarch : High-Availability Add-on for NFS-Ganesha and Samba
storhaug-nfs.noarch : storhaug NFS-Ganesha module
Given that I'm missing that one package above, will configuring using
ganesha-ha.conf still work? Or should I be looking at another option
alltogether?
Appreciate any help. Ty!
