[Lustre-discuss] lfs check servers and lbug problem

[Lex]

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.
