When starting the client, you need to use "lconf --node client
config.xml",
or zconf mount "mount -t lustre dell-161:/mds161/client /mnt/lustre".

I installed the Lustre-1.2.4 on two machines "dell-161" and
"dell-162"
(both with redhat as 3.0, kernel 2.4.21).
Everything goes well when using "sh local.sh" and "lconf
local.xml" on
each machine. Now I want to configure a MDS
and a OST on dell-161, and a client on "dell-161".

I am using the same configuration "config.sh" on the tow nodes.

Any suggestion is appreciated.
Thanks!
