I'll think about which route i want to go, since i only want to mirror the <br>
partition for the win10 vm as all my linux stuff is in fact backed up over the <br>
network. the mdraid seems simpler i think as long as both routes allow a <br>
mirrored partition loss to not result in loss of data and it being easy to get <br>
the mirror back with new hardware. either way would leave me with a fixed <br>
size windows volume, since any other space on either drive would not be <br>
mirrored - if i understand this correctly. unless it would be possible at a <br>
later date to create a second mirrored set of lvm volumes and add them to the <br>
first?<br>
