Hello Herbs,
this setup is not as easy as it sounds. Here you can find additional setup instructions (look for the chapter of NFS-Ganesha HA):
Maybe you should use Gluster3.10 because the setup for 3.9 and 3.8 is not stable. With Gluster 3.10 I had a stable HA-Cluster.
Also you should be aware of the fact, that since Gluster 3.11 this setup may not work because the Developers switching to storhaug:
At the moment there is confusing in the coummunity about that issue. Storhaug is not complete and still under development.
I don't know if my informations are up-to-date. Because of that fact I was switching to Samba (SMB). You can also have a HA Cluster with Samba/CTDB.
Regards
David Spisla

All,I would like to set up HA NFS (Active/Active) on our 2 node gluster environment using NFS-Ganesha.Specs:- RHEL 7- glusterfs 3.8.15 built on Aug 16 2017 14:48:01I am following this process in this documentation, however it is confusing to me:I already had Pacemaker/Corosync up and running on the our 2 node gluster environment with fence resources on each.After the package installs and confirming "Pre-requisites to run NFS-Ganesha", here is what I've done:1. # gluster volume set all cluster.enable-shared-storage enable2. Create /etc/ganesha/ganesha-ha.conf file (scrubbed. I'm also assuming that HA_NAME should be equal to the already created pacemaker cluster name):## HA FileHA_NAME="clustername"HA_CLUSTER_NODES="server1,server2" VIP_server1="10.19.3.66"VIP_server2="10.19.3.67"3. # gluster nfs-ganesha enableEnabling NFS-Ganesha requires Gluster-NFS to be disabled across the trusted pool. Do you still want to continue?(y/n) yThis will take a few minutes to complete. Please wait ..nfs-ganesha : success4. # gluster volume set vol1 ganesha.enable onvolume set: successAt this point I can see the export available:# showmount -eExport list for server1:/vol1 (everyone)And I can successfully mount the export from another server.However, nothing appears to be done regarding HA. nfs-ganesha is not started on server2 and no additional resources are created in pacemaker.Can anyone provide guidance as to what I may be doing incorrectly?Thanks,HB
