OK, that means, over time, data will be distributed across all mirrors? (assuming all blocks will be written once) I think a useful extension to ZFS would be a background task which distributes all used blocks across all vdefs. I don't know if this can be established with ZFS but it will end up with reading one block of the pool after another assuming that by writing it, it will be spread across the mirrors. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
