I've been building C7 VMs with RAID-1 in Virtualbox these last couple
of days, to pin down exactly how to do it. based on the link above,
but I'm making "real" partitions instead of LVM.

The current iteration seems to be running fine, but I had an odd problem
when configuring the partitions: for two 10 gig virtual drives, it wouldn't
let me use the last gig of space. or maybe it has some other issue on the
max partition size,... it seemed to max out at around 9900 MB. This for
sure won't do when I build it on real hardware, so I'm wondering if
anyone else here has a clue what's going on??

thanks in advance!
