gvinum and RAID

[tradigan at newrevolutions.net]

Is it possible to use gmirror for a small partition on two disks and then
use gstripe on the remaining disk space of those drives to create a larger
stripe?

I didn't think that was possible.  I could be wrong however :).

If that will work, that would be my best option right there.
