mdadm-2.0 was released a couple of weeks ago: http://www.kernel.org/pub/linux/utils/raid/mdadm/ANNOUNCE http://www.kernel.org/pub/linux/utils/raid/mdadm/ Currently 1.11 is being shipped. I'm not sure we'd want to push 2.0 to FC4 though, but certainly an update into -devel would be good.
mdadm is now up to 2.1. It would be good if this was in FC5 (bumping priority - can this be tagged as a blocker?).
Cool, I see 2.1 is now in rawhide. Thanks to wtogami :) Closing off as resolved........
