I have a physical linux server that I'm considering moving to a virtual linux server running on the standalone Hyper-V R2 hypervisor. Theres alot of unused cycles on that box that could be shared with other machines. Normally this would be a pretty easy choice, but this particular server is hosting an mdadm raid5 array on it. Once I get a similar linux virtual server running, is there a way to add the discs that make up the array to the virtual machine and have it use them directly?
In other words, I dont want to have to convert them all to virtual discs and then rebuild the array; I want to just use the existing discs and partitions in a kind of 'pass through' mode. The array is working just fine, I dont want to go through all the I/O of moving it off these discs to new, virtual, ones. Hyper-V supports a mode called 'passthrough', would that do the trick?
