I am going to be using something called gluster storage platform which can be referenced at gluster.com. I have followed the instructions and copied the files to the usb and then tried to boot to it from no avail.
Now I am starting over and trying to do everything through the terminal, mount usb, format the filesystem, download the files, copy to the usb to make it bootable. The link below gives detailed instruction on what I'm trying to do. It suggests that the server or machine needs to be made able to boot from usb, but that has already been done. If anyone can provide detailed instructions, it would be greatly appreciated! Please see the link below. I have a machine running CENTOS and a machine running UBUNTU.
