Re: [lustre-discuss] Lustre 2.8.0 - MDT/MGT failing to mount

Hm, I'm not sure everyone here is talking about the same ordering... As I understand it: The writeconf process is to unmount everything, then writeconf all your targets (order doesn't matter, pretty sure - Someone will correct me if not...), then mount in the order Colin gave - MGS/MDT, then
