Currently, ZFS will not reorganize the existing data for such cases. You can force this to occur by copying the data and removing the old, but that seems like a lot of extra work for most cases. > e.g. Take a pool with 1 vdev consisting of a 2 disk mirror.

Yes. AFAIK, nobody has characterized resilvering, though this is about the 4th time this week someone has brought the topic up. Has anyone done work here that we don't know about? If so, please speak up :-) -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
