Your performance scales with the number of vdevs, and its better to combine them into a single pool as you combine the performance. Generally, unless you want different behaviour from different pools, it's easier to combine them. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
