Hi Colin Sorry for replying you late
I resolved my problem by activating my OST back: lctl --device 18 conf_param lustre-OST000d.osc.active=1 and use lctl --device number deactivate to manually deactivating that ost on my clients. And after, that i can mount lustre on my client smoothly ( manually deactivating ost after mounting, certainly ). Many thanks for your soon reply.
