If you need to install bootblocks, it doesn't matter when you do it. But I found the answers I want, I think what I need to do is: zpool attach export disk#0 disk#1 (this makes the single pool into a mirror) And if resilvering is done, I can use: zpool replace export disk#0 disk#2 Right? (Just like to make sure that I can remove disk#0 at one point) Casper _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
