I realized too late that OMV does not need very much space for the OS, and that others have used a USB drive to store the OS. My build is a mini-ITX build in a small form-factor ThermalTake case.
OMV4.x is installed on a 120GB (or similar size) SSD, but since it's barely taking up much space on that drive, I was wondering if I could use the remaining space to host other images of Linux (e.g. CentOS, OpenSUSE, etc) and use virtualbox or VMWare.
My build has primarily been used for media storage, but I was hoping to give myself more options, or to play around with what OMV has to offer.
A related question that I couldn't find solid answers for online is concerning a HDD I ordered from amazon. I received a 4TB drive that when plugged in will heat up very quickly. It's not scalding, but it's considerably hot.
I did not catch this when it was initially installed into my case next to my other drives, so I am concerned about the health of the other drives.
