Mirroring without Vinum (GEOM?)

[Eirik Oeverby]

Hi all,

is there a way, given GEOM and all, to mirror volumes in -CURRENT without 
using Vinum? Vinum doesn't work at all on amd64, and I don't even know if 
it works in -CURRENT, so I'm looking for alternatives. Given that my SATA 
RAID controller (Silicon Image) isn't supported beyond single-drive mode 
either, a software RAID solution is needed.

Anyone?
