That's the wrong way round, I think. If you lose a drive, then you've
the whole of one of your stripes and have no resilience. Shouldn't you
rather stripe the mirrors:
gmirror gm0 da1 da2
gmirror gm1 da3 da4
gstripe gs0 gm0 gm1
newfs gs0
This way if you lose a drive then only one of your gmirrors loses
resilience and the other half of your disk space is unaffected.
Cheers,
Matthew
