If booting of a stripe of 3 mirrors should work assuming no BIOS bugs, can you explain why is booting off simple stripes (of any number of disks) currently unsupported? I haven't tested that myself, but everywhere I look seems to indicate that booting off a simple stripe doesn't work or is that "everywhere" also out of date after your changes? :) - Sincerely, Dan Naumov
