This worked. I've restarted my testing but I've been fdisking each drive before I add it to the pool, and so far the system is behaving as expected when I spin a drive down, i.e., the hot spare gets automatically used. This makes me wonder if it's possible to ensure that the forced addition of a drive to a pool wipes the pool of any previous data, especially any zfs metadata.
I'll keep the list posted as I continue my tests. Jim This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
