[Linux-cluster] cluster problem rhel as 4.2 and

[Omer Faruk Sen]

Hi,

I have setup a simple cluster. Everything goes fine .. Cluster services
get started and I can manually restart cluster service without any
problem. But if I manually edit /etc/httpd/conf/httpd.conf  (to make it
not to work by rhcs) normally when I try to restart cluster it doesn´t
work but when I re-edit httpd.conf so cluster can work I can´t start
cluster. I always get error whatever I do until I reboot my system. I use
manual fencing to test it but I think it makes no problem since I don´t
use a shared storage.

I have found that the problem seems to be /etc/rc.d/init.d/cman script.
When I try to restart it it tries to reload dlm module. I use RHEL AS 4.2
(no up2date was done) and rhcs that can be downloaded from rhn (as iso). I
thínk this is a bug and I want to learn if this was resolved. By the way I
have added different services (vsftpd, nfs ... and proved that it is not
related with httpd ....)

Here is my cluster.conf:

<?xml version="1.0"?>
<cluster config_version="57" name="nns">
        <fence_daemon clean_start="0" post_fail_delay="0"
post_join_delay="3"/>

                <clusternode name="node2" votes="1">
                        <fence/>
                </clusternode>
        </clusternodes>
        <cman expected_votes="1" two_node="1"/>
        <fencedevices>

        </fencedevices>

                                <failoverdomainnode name="node2"

                        </failoverdomain>
                </failoverdomains>
                <resources>
                        <script file="/etc/rc.d/init.d/httpd" name="httpd"/>
                        <ip address="192.168.2.100" monitor_link="1"/>

                </service>

</cluster>
