I have been working on making vdsm-gluster python 3 compatible. I had some queries regarding the tool used for getting storage devices info. Till now vdsm uses python blivet for getting the device tree information.

I am not sure if blivet is compatible with python 3 so I had two propositions which I want some advice on.

1) Using lsblk and parsing the output

2) Using ansible modules locally in the vdsm hosts.

Although I feel the 2nd way will add more dependencies to the project but it can help us in the long run to add more functionality easily. 

Thanks,
