Description Alban Crequy 2005-07-06 10:03:05 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.7.2) Gecko/20040804

Description of problem:
Gulmd use the default network interface to communicate with other nodes, instead of the network interface I set in nodes.ccs

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Get a cluster with one gulm server.
2. Set nodes.ccs with the network interface I want (eth1):
ip_interfaces {
                eth1 = ""
} ...
3. Start GFS.
4. Start a program that use a lot of locks/unlocks between the nodes
3. Check with tcpdump eth0 and eth1 on port 41040(gulm) that gulm use eth0 or eth1.

Actual Results:  tcpdump show that gulm use eth0 ( instead of eth1 (

Expected Results:  tcpdump should show that gulm use eth1 because I set eth1 in nodes.ccs and I set the IP of eth1 in nodes.ccs

Additional info:

The relevant code is in:

This piece of code have changed in the CVS version:

But need to use a stable version of GFS on a Linux kernel 2.4.

Comment 1 michael conrad tadpol tilstra 2005-07-06 12:52:28 UTC
you did remember to add the following line to each node entry, right?
  usedev = "eth1"

Comment 2 Alban Crequy 2005-07-06 13:16:29 UTC
No, I didn't know the option "usedev". And the documentation
does not mention it, but I just find the documentation errata which mention it.

Thank you for your help. I guess you can close this bug now.
