Not sure if this will help, but our company is building out an open source
NAS. We are still not completely done, but we are nearly done. If you would
like to experiment , do let us know.

Here is the docs link :

We should have the iso built out in another week.

If this interests, and would love to experiment, do reply back as a PM, and
I would direct you to the relative sources.
