Maybe freebsd-geom would be better. I read your original question on the -fs. I don't have any experiences with graid and only few with ataraid. We used gmirror instead, because it is more universal (supporting migration of disks between different machines) Anyway - I think it can be possible to use graid with existing data, because both should use the same metadata format (depending on HW / BIOS manufacturer). You can try it with some FreeBSD 9 Live CD / USB booted system with a custom kernel (without ataraid support) and with graid loaded as a module. Then you will see if your existing array will be recognized or not. Miroslav Lachman PS: don't try it on a production system without proper backup of your valuable data.
