It would be great to have, but it's rather hard to do, because gmirror, just like most other GEOM classes, stores its metadata at the end of the provider. I've also asked Alexander Motin about metadata formats supported by graid(8), and it looks like all of them have the same problem. It is possible to implement it after this patch goes in, but it was not part of the project. --=20 If you cut off my head, what would I say? Me and my head, or me and my = body?
