If your ZFS version is new enough, there is a "zpool split" command you can use, for just this purpose. It splits a mirror vdev in half and assigns a new pool name to the drive you are removing. You can then use that drive to create a new pool, thus creating a duplicate of the original pool. -- Freddie Cash fjwc...@gmail.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
