[OSR-users] Problem with bond configuration
|

Hi Marc,
very very thank for your answer.......... I was becoming crazy !!!
I tried and now it works.
I take advantage of this email to ask for other informations.
- It's possible configure two network interfaces of the server in
order to
have two interfaces Bond, for example bond0.11 and bond0.22,
one for communication intra-cluster and the other for the service
configured on the cluster ??
- The ip address configured for the service given by the cluster, for
my files cluster.conf:
<resources>
<ip address="10.43.100.204" monitor_link="1"/>
<script file="/etc/init.d/httpd" name="httpd"/>
</resources>
<service autostart="0" domain="failover" name="HTTPD">
<ip ref="10.43.100.204"/>
<script ref="httpd"/>
</service>
I have to configure on a node of the cluster
<clusternode name="clu01" votes="1" nodeid="1">
<com_info>
<syslog name="clu01"/>
<rootvolume name="/dev/sda2" fstype="ocfs2"/>
<eth name="eth0" ip="10.43.100.203" mac="00:15:60:56:75:FD"/>
<eth name="eth1" ip="10.43.100.204" mac="00:15:60:56:75:FC"/>
</com_info>
</clusternode>
If I want to relocate the service on the node_2 when the node_1 fails,
I must also configure the ip (10.43.100.204) in the section <com_info>
of the node_2 ??
- It's possible to configure a service, for example httpd,
to be active simultaneously on multiple nodes instead
of having it running on one node and move it when the node falls ??
Thanks
