ganesha-ha.conf

Description of problem:

Hello, using Red Hat Gluster Storage 3.1 based on GlusterFS 3.7.9 on RHEL 7 with Ganesha NFA HA, with a cluster with 3 nodes (2 + 1 dummy) and 1 replica 2 ganesha.enable on volume.
I got lots of warning from /var/log/messages from ganesha heartbeat. I configured nodes as shown in the documentation example [1][2]

Using FQDN for hostnames, such as node1.example.local, node2.example.local in /etc/ganesha/ganesha-ha.conf

Attached ganesha-ha.conf


looking at the code [1] it looks that the short name of the hostname is used to trigger heartbeat, so I was wondering if FQDN HA_CLUSTER_NODES are supported with ganesha heartbeat or if I miss something.

My /etc/resolv.conf contains:

domain example.local
search example.local
nameserver 10.0.1.2
nameserver 10.0.1.3

How reproducible:


Steps to Reproduce:
1. Install ganesha nfs ha
2. Configure cluster nodes with FQDN and start a ganesha volume
3. check /var/log/messages for warnings

Actual results:
 ganesha_mon(nfs-mon)[31542]: INFO: mon monitor warning: crm_attribute --node=node1 --name=grace-active --update=0 failed


Expected results:

no warning
