[Lustre-discuss] Re: [lustre first install...] problems with test scripts on single node

hi all,

I have just finish to install lustre 1.4.7.3 on my redhat enterprise 4
(2.6.9-42.0.2.EL_lustre.1.4.7.3smp)...

- I have created the local.sh as explain in the howto
- I launched as specified :
   $ sh local.sh
   $ lconf --reformat local.xml

it seems to work find, but the scripts hangs on lctl command (I think)...

Anyone can help?

Thanks.

Happy new year!
Nicolas



================================here is my local.sh file
================================
#!/bin/sh

# local.sh

# Create node

lmc -m local.xml --format --add mds --node localhost --mds mds-test

[Lustre-discuss] Re: [lustre first install...] problems with test scripts on single node

Are there any kernel messages from Lustre (dmesg)?
I bet it will say:

LustreError: Unexpected error -11 connecting to 127.0.0.1@tcp at host 127.0.0.1
on port 988

The issue in that case is that you can''t use anything that resolves to 
the loopback address 127.0.0.1
Lustre can only use non-loopback IPs. 
Instead of "--nid localhost --nettype tcp"
use "--nid 1.2.3.4@tcp --nettype lnet"
