Correct, but not always sufficient. I forget the name of the parameter, but there's some rate limiting thing that limits how fast you can fill the L2ARC. This means sometimes, things will expire from ARC, and simply get discarded. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
