[Pacemaker] Pacemaker on RHEL 4.8

Wed Nov 24 11:55:09 EST 2010

Hi,

I’m also having problem with pacemaker / heartbeat on RHEL 4.8.

First of all clusterlabs repo for epel doesn’t work with yum on RHEL 4.8
(yum is installed from EPEL):

[root at lucija ~]# yum search pacemaker

Here is the pacemaker.repo:

[root at lucija ~]# cat /etc/yum.repos.d/pacemaker.repo

[clusterlabs]

name=High Availability/Clustering server technologies (epel-4)

baseurl=http://www.clusterlabs.org/rpm/epel-4

type=rpm-md

gpgcheck=0

enabled=1

If I install it by hand if says it need python2.4, so I installed it from
fedora rpms (http://www.python.org/download/releases/2.4.2/rpms/). I then
copied crm python files to python2.4 and modified crm script to use
python2.4.

Pacemaker, heartbeat and crm now run, but are buggy:

*- If I edit configuration I often get an error that xml in CIB can not be
replaced. I got this when I tried to change res_ftp monitor timeout to 40s:*

[root at ankaran ~]# crm configure edit

*ERROR: could not replace rg_ftp*

INFO: offending xml: <group id="rg_ftp">

        <primitive class="ocf" id="res_ip_ftp" provider="heartbeat"

                        <nvpair

                </instance_attributes>

                <operations>

                        <op id="res_ip_ftp-monitor-15s" interval="15s"
name="monitor" timeout="30s"/>

                </operations>

        </primitive>

        <primitive class="lsb" id="res_ftp" type="vsftpd">

                <operations>

                        <op id="res_ftp-monitor-15s" interval="15s"
name="monitor" timeout="40s"/>

                </operations>

        </primitive>

</group>

*- If I try to stop a group rg_ftp, I the node on which group runs exits and
rejoins the cluster:*
