indeed, but this is not the same as expansion of an existing vdev because you still have the same number of spindles, with potentially more data on each, so it may in fact be a net performance loss. I don't think the only driver for wanting to expand a raidz vdev is to gain more space... grant. _______________________________________________ zfs-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
