Thanks for the reply.
It seems you have been working with it?
I am currently testing a Ubuntu setup in a Oracle virtualbox (on Win10), and allthough Ubuntu / Linux can make an experienced Windows user feel completely helpless at times, it only took me 2 or 3 hours to get a setup running, that will do the things I need it to.
So not that frightening after all, but a lot of Googling....
Is it easy to setup Rockstor in Proxmox, and maintain as much of the current setup as possible? Could I setup Proxmox on another drive (I have an SSD ready for the task), and then boot the current Rockstor install in a VM, or would it need to be a new install?
I'm thinking of letting Rockstor have access to all cores and 6GB mem, and then let Ubuntu run on 2 cores 2GB mem.
The computer is an older Phenom 940 3Ghz with 8GB ram, on which Rockstor runs rock solid.
