Lustre devel - Mar 2012 - Some questions about Lustre test configuration

Hi all,

I have some questions about Lustre test configuration, would somebody help on
this?  Thanks a lot.


1.       Seen from the test sets of Maloo, typically four nodes are used:
"Client1, Client2, MDS1, OSS(includes 7 OSTs)".

So in a normal regression testing, we can also follow this, right?

When four nodes are used, what value do you set for the following two variables
in file cfg/local.sh:

mdsfailover_HOST  and ostfailover_HOST



2.       I see that in the PDF "Lustre 2.2 Test Plan", these are some
links introducing about the test configuration. Like the following one:



Regression Testing

Use auster to run automated regression tests with the following configurations.

http://wiki.whamcloud.com/display/ENG/Auster .


                But we failed to access this kind of link.  Is this URL public
to users outside Whamcloud?

Thanks & Best Regards,
Kelly Zhang(EMC)

In the this configuration, I believe the failover hosts should be set to
nonfailover hosts:

mdsfailover_HOST=${mds_HOST}
ostfailover_HOST=${ost_HOST}

This will allow the recovery tests to do simulated failover by ummounting and
and mounting the targets on the same node to trigger Lustre recovery.
