HI,
So, we have 3 nods in the cluster ( 2 resource + 1 voting node) and The main
purpose is to deliver the shares over NFS to the customer
Node List:
* Online: [ host1, host2 ]
Full List of Resources:
* Resource Group: NAS-GATEWAY:
* mdadm0 (ocf::heartbeat:mdraid): Started host1
* mdadm1 (ocf::heartbeat:mdraid): Started host1
* nas_cluster_lvm (ocf::heartbeat:LVM-activate): Started host1
* nfsshare (ocf::heartbeat:Filesystem): Started host1
* nfs-daemon (ocf::heartbeat:nfsserver): Started host1
* nfs_vip (ocf::heartbeat:IPaddr2): Started host1
Daemon Status:
corosync: active/enabled
pacemaker: active/enabled
pcsd: active/enabled
sbd: active/enabled
I will try to test the csync2 tool, but the problem might be find signed csync2
rpm package for Red Hat,

I incline to ask you describe your use case a little bit more. Without knowing
it well, my view might be not fit you.
csync2 is often used by ClusterLabs community. But it is an individual tool,
and is not part of pacemaker.
https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_linbit_csync2&d=DwIDaQ&c=uc5ZRXl8dGLM1RMQwf7xTCjRqXF0jmCF6SP0bDlmMmY&r=UzPNWvRnAChMyFZDGSUcEqtZElcu_XngP1GiT3HLUmI&m=0VgPA72qP5XpAr9TzizFodvYwOGTjSCkkrP_lbJSxW_0eg3Jut93Dbd6CL50Le0f&s=HuUc_fj7dKBgCr92yqVJyYjWAWU1ivqn0uXuGKk6mLo&e=
However, you refers to /etc/exports. I guess your use case is High Available
NFS? If so, you could leverage `man ocf_heartbeat_exportfs`. But this resource
agent doesn't use /etc/exports at all.

Roger
