Lustre discuss - Oct 2006 - How to clear MGC Cache?

Hi,All:
     
     I setup Lustre beta 5 on my hardware.
It works fine before I changed the IP address
of MDS. OST MGC Cache  seems remember the old IP
address of MDS. That is to say, MGC of OST hold 
two IP addresses: old  one and new one.

    Can anybody tell me how to clear the old
configuration infomation from mgc cache?

stop all servers including the mgs,
run
tunefs.lustre --writeconf </dev/mgs>
start the mgs again then all other servers.
