I am trying to setup Ovirt with a self hosted engine and NFS storage for said engine.  The storage appears to mounting OK, but when it gets to the point that it is initializing the lockspace it fails spectacularly and shows a Python traceback which I cleaned up and have included below:

Traceback (most recent call last):

The messier ansible output is below:

I am a bit lost on how to proceed as I haven't implemented a self-hosted engine before and I haven't found anything that helps online so far.  Thanks in advance for any assistance.
