This error message occurs when the disks are of different size and the disk being attached is smaller. I would double check (using format) that the number of available blocks is the same. Note: to boot you will need to ensure that a Solaris VTOC label is on both disks. If you let ZFS add the mirror without specifying the slice, then ZFS will add an EFI label and the disk will not be bootable. Please see the appropriate docs which provide guidance on configuring boot mirrors. http://www.opensolaris.org/os/community/zfs/docs/zfsadmin.pdf -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
