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 14:48:01
I 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 enable
2. 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 File
HA_NAME="clustername"
HA_CLUSTER_NODES="server1,server2"
VIP_server1="10.19.3.66"
VIP_server2="10.19.3.67"
3. # gluster nfs-ganesha enable
Enabling NFS-Ganesha requires Gluster-NFS to be disabled across the trusted pool. Do you still want to continue?
(y/n) y
This will take a few minutes to complete. Please wait ..
nfs-ganesha : success
4. # gluster volume set vol1 ganesha.enable on
volume set: success
At this point I can see the export available:
# showmount -e
Export 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
