[Gluster-users] Gluster and NFS-Ganesha - cluster is down after reboot

[Rudolf]

Hi Gluster users,

First, I'd like to thank you all for this amazing open-source! Thank you!

I'm working on home project – three servers with Gluster and NFS-Ganesha.
My goal is to create HA NFS share with three copies of each file on each
server.

My systems are CentOS 7.3 Minimal install with the latest updates and the
most current RPMs from "centos-gluster310" repository.

I followed this tutorial:
http://blog.gluster.org/2015/10/linux-scale-out-nfsv4-using-nfs-ganesha-and-glusterfs-one-step-at-a-time/
(second half that describes multi-node HA setup)

with a few exceptions:

1. All RPMs are from "centos-gluster310" repo that is installed by "yum -y
install centos-release-gluster"
2. I have three nodes (not four) with "replica 3" volume.
3. I created empty ganesha.conf and not empty ganesha-ha.conf in
"/var/run/gluster/shared_storage/nfs-ganesha/" (referenced blog post is
outdated, this is now requirement)
4. ganesha-ha.conf doesn't have "HA_VOL_SERVER" since this isn't needed
anymore.

When I finish configuration, all is good. nfs-ganesha.service is active and
running and from client I can ping all three VIPs and I can mount NFS.
Copied files are replicated to all nodes.

But when I restart nodes (one by one, with 5 min. delay between) then I
cannot ping or mount (I assume that all VIPs are down). So my setup
definitely isn't HA.

I found that:
# pcs status
Error: cluster is not currently running on this node

and nfs-ganesha.service is in inactive state. Btw. I didn't enable
"systemctl enable nfs-ganesha" since I assume that this is something that
Gluster does.

I assume that my issue is that I followed instructions in blog post from
2015/10 that are outdated. Unfortunately I cannot find anything better – I
spent whole day by googling.

Would you be so kind and check the instructions in blog post and let me
know what steps are wrong / outdated? Or please do you have more current
instructions for Gluster+Ganesha setup?

Thank you.

Kind regards,
Adam
