Thanks, after reading it makes sense. I suppose I need to drop my hope of having sharing possibility with the host. I have two questions that you might be able to answer: 1. Does direct LUN support partitions or only whole devices 2. Do you know of any open source way of making them shareable to Ovirt?
My setup is simple: - HP DL380 with dual Xeon and lots of RAM. Boots from seperate disk (USB) - MSA60 with p411 attached to the HP DL380 When we grow oVirt we will grow with DL360¹s and use all shared storage from the guest fileserver on the first host.
