[Lustre-discuss] Help

[Nihir Parikh]

Hello Wang Yibin,
Thanks for getting back to me. Yes, S2 and S3 can ping each other using lctl ping. I was using nuttcp test and I also tried ib tests that comes with the IB utilities. I will lnet-selftest.

My goal was to measure the bandwidth when it has to reach across different network. Are there any such tests specific to lustre?

Thanks
Nihir

Hi,

Now my problem is to run some network tests from S2 --> S3 and S3 --> S2 to measure the bandwidth but somehow both S2 and S3 complain that network is unreachable. What am I doing wrong?

Your configuration seems OK to me. Can S2 and S3 ping each other using 'lctl ping'?
What kind of network test did you do? Note that only lustre LNET can do the routing.
There's a script in lustre testsuite that's specifically for testing the network connectivity - lnet-selftest.sh.



Thanks
Nihir
