[ovirt-users] Self hosted engine fails after 4.2 upgrade

[Stefano Danzi]

Hello!
I have a test system with one phisical host and hosted engine running on it.
Storage is gluster but hosted engine mount it as nfs.

After the upgrade gluster no longer activate nfs.
The command "gluster volume set engine nfs.disable off" doesn't help.

How I can re-enable nfs? O better how I can migrate self hosted engine 
to native glusterfs?
