One other (risker) option would be to export the pool and grow slice 0 in emcpower2a so that it consumes the entire disk. Then reimport the pool and we should detect the new size and grow the pool accordingly. You want to make sure you don't change the starting cylinder so that we can still see the front half of the labels. I've been able to successfully do this with EFI labels but have not tried this with VTOCs. If you do decide to go this route, a full backup is highly recommended. - George _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
