Two ideas that may not help. :) 1. Buy a SATA card (no raid) for debian to use, leaving the on-board fake raid for 'doze. 2. Install debian on all four drives and use one of the virtualization systems (e.g. Xen, but there are many others), and install 'doze in a virtual box. For (2), since you want raid1 you have a couple of choices: a) two separate raid1 arrays then a raid0 array made of both, with LVM over top. b) two separate raid1 arrays then LVM over top with the LVs striped. c) single 4-disk raid5 array with LVM on top. Option c gives you the most space efficiency (3 drives worth of data on 4 drives). In any event, raid arrays can't be easily reconfigured; think of them as monlithic. To add space later, create a new array with new disks, make the array a PV and add it to the applicable VG. That's the joy of LVM. YMMV.
