Keep in mind that corosync/pacemaker is hard for proper setup by new admins/users.
I'm still trying to remediate the effects of poor configuration at work.
Also, storhaug is nice for hyperconverged setups where the host is not only hosting
bricks, but other workloads.
Corosync/pacemaker require proper fencing to be setup and most of the stonith resources
'shoot the other node in the head'.
I would be happy to see an easy to deploy (let say 'cluster.enable-ha-ganesha
true') and gluster to be bringing up the Floating IPs and taking care of the NFS
locks, so no disruption will be felt by the clients.
Still, this will be a lot of work to achieve.

I'm using nfs-ganesha in my next upgrade so my client systems can use NFS instead of
fuse mounts. Having an integrated, designed in process to coordinate multiple nodes into
an HA cluster will very welcome.
