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.<br>

Hi all, <br>
<br>
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. <br>
<br>
I am just starting with nfs-ganesha and following the doc<br>
<a href="https://docs.gluster.org/en/latest/Administrator%20Guide/NFS-Ganesha%20GlusterFS%20Integration/" rel="noreferrer noreferrer" target="_blank">https://docs.gluster.org/en/latest/Administrator%20Guide/NFS-Ganesha%20GlusterFS%20Integration/</a><br>
<br>
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?<br>
<br>
Thank you, <br>
Alex<br>
