[Linux-cluster] Alternate NIC for clustering

Sorry if this reply is a repeat.  I sent a reply to this post when my mail client
was foolishly not set for plaintext emails only.  As far as I can tell the list
manager has stripped it, but it could just be slow.  Apologies again if that's
the case.

Hi,

Your issue is likely not to be cluster related, but a problem with routing or
name resolution.

Please send the outputs of the following commands to me privately (not replied to
the list) so I can assist:

cat /etc/nsswitch.conf
netstat -rn
ip rule show
ip route show
cat /etc/hosts
cat /etc/resolv.conf
nslookup 172.38.1.17
nslookup 172.38.1.18
nslookup 192.168.190.86
nslookup 192.168.190.87
nslookup ricci1b.gallup.com
nslookup ricci2b.gallup.com
nslookup ricci1b-ic.gallup.com
nslookup ricci2b-ic.gallup.com
ifconfig -a
Any configs that relate to how eth1 and eth2 are bonded.

Also, not that I think it makes a difference, but 172.38.0.0 is *not* a part of
the IANA reserved address space for private use (if that's what you were
intending).  For further info, please read section 3 of RFC 1918 at
http://www.isi.edu/in-notes/rfc1918.txt.  I doubt this would relate to your
problem, however.

Regards,

Stewart

Does anyone know how to get the cluster to use an alternate private network for
clustering?  I have 2 nodes RHEL 5.3

Eth0 is the public interface

Eth1 and eth2 are bonded

I added entries for the bonded interface in both hosts file.  Here is my hosts file

 

192.168.190.86  ricci1b         ricci1b.gallup.com

192.168.190.87  ricci2b         ricci2b.gallup.com

172.38.1.17     ricci1b-ic      ricci1b-ic.gallup.com

172.38.1.18     ricci2b-ic      ricci2b-ic.gallup.com

 

Here is my cluster.conf

<?xml version="1.0"?>

<cluster alias="xencluster" config_version="1" name="xencluster">

        <fence_daemon post_fail_delay="0" post_join_delay="3"/>

        <clusternodes>

                <clusternode name="ricci2b-ic.gallup.com" nodeid="1" votes="1"/>

                <clusternode name="ricci1b-ic.gallup.com" nodeid="2" votes="1"/>

        </clusternodes>

        <cman expected_votes="1" two_node="1"/>

        <fencedevices/>

        <rm/>

</cluster>

 

I get this error in my log file

 

Feb 12 11:34:27 ricci1b openais[6353]: [MAIN ] local node name
"ricci1b.gallup.com" not found in cluster.conf

 

Thanks
