Why do you have a MDS active? I'd suggest getting rid of that at least until you have everything else working. I see you've set nodown on the OSDs, did you have problems with the OSDs flapping? Do the OSDs have broken connectivity between themselves? Do you have some kind of firewall interfering here? I've seen odd issues when the OSDs have broken private networking, you'll get one OSD marking all the other ones down.
