I had a similar situation. Starting with a single disk containing the root pool, I added a second disk and mirrored them manually into the same zpool. Then I created a second boot environment in the same pool and did a live upgrade from build 94 to build 95. That operation seems to have written the GRUB stages onto both disks. I can boot either one to get the same GRUB menu and the same default Nevada build. I'm very impressed with how well ZFS and Live Upgrade work together. -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
