[Pacemaker] Pacemaker: failed to load external entity - XML issue?

[JECH Ladislav]

Hi,

 

I used only Heartbeat package for clustering only the HTTPD daemon.
Another software I want to cluster is Oracle Database Express. I red
documentation and features and decided I will switch to
openais(corosync) and pacemaker as advanced resource manager. I just
went trough installation procedure as described at
http://www.clusterlabs.org/wiki/Install
<http://www.clusterlabs.org/wiki/Install> . I have 2 node cluster and my
systems run CentOS 5.4. From added repository it installed Pacemaker:

pacemaker                                  i386
1.0.8-5.el5   

pacemaker                                  x86_64            1.0.8-5.el5

 

My libxml2 library is following:

libxml2                                    i386
2.6.26-2.1.2.8

libxml2                                    x86_64
2.6.26-2.1.2.8

 

command "grep ERROR: /var/log/messages | grep -v unpack_resources" has
following output:

Your current configuration could only be upgraded to pacemaker-0.7...
the minimum requirement is pacemaker-1.0. - this is also strange to me.

 

This output still repeats afters some seconds....seems like some issue
with schema, all other packages are latest from repo at
http://clusterlabs.org/rpm/epel-5/x86_64/

 

Any idea about how to fix this situation?

 

Many thanks,
