Hi Alex,

I have been playing arround with the NFS Ganesha on EL8 and I was surprised that
the solution deploys the cluster with a 'portblock' resource which is
relying on IPTABLES, when the default is NFTABLES... Also, some selinux issues
came up.
I think that Ganesha with Pacemaker integration is quite good and reliable and
will ensure that your NFS clients will remain operational.

Also, it's worth noting that RHEL support only corosync/pacemaker setup .

Best Regards,
Strahil Nikolov

Hi all,

I would like to export gluster volume (which is a replica 3) with NFS so as to
use for persistent container storage. I can directly use gluster storage plugin
from docker containers though it seems that this approach uses FUSE mount. I
have read that nfs-ganesha i using libgfapi which provides better performance
thus trying to use NFS through it.

I am just starting with nfs-ganesha and following the doc
https://docs.gluster.org/en/latest/Administrator%20Guide/NFS-Ganesha%20GlusterFS%20Integration/

I am a bit confused with the best approach for high availability. I am already
using pacemaker/corosync for other services and have a virtual IP for the
cluster. I was thinking that each container can use the locally exposed NFS
share (using localhost as the IP/domain of the NFS server, each container its
own separate share). Reading the HA setup at the above link, it mentions the use
of ganesha-ha.conf which incorporates some? HA_CLUSTER_NODES? etc parameters. I
do not see the reason to go like that since HA is managed from gluster already.?
Also at same doc it mentions that this HA approach is to be replaced from
storhaug which when checking at github seems like an idle repo for years.? What
is the best approach for HA using nf-ganesha?

Thank you,
Alex
