Hi,
Has anybody successfully configured Pacemaker+LVM2+DLM+CLVMD under CentOS 5.3?
I am running pacemaker-1.0.4-23.1 previously available from  http://download.opensuse.org/repositories/server:/ha-clustering/CentOS_5/x86_64/
I need to enable cluster controlled LVM locking.
Novel have released a great document at http://www.novell.com/documentation/sle_ha/pdfdoc/book_sleha/book_sleha.pdf 
-          however CentOS repository is missing the appropriate lvm2-cluster related packages. 
I tried "compromising" by using from CentOS:
For DLM:
cman-2.0.98-1.el5.x86_64.rpm       
perl-XML-LibXML-Common-0.13-8.2.2.x86_64.rpm     
pexpect-2.3-1.el5.noarch.rpm
perl-Net-Telnet-3.03-5.noarch.rpm  
perl-XML-NamespaceSupport-1.09-1.2.1.noarch.rpm
perl-XML-LibXML-1.58-5.x86_64.rpm  
perl-XML-SAX-0.14-5.noarch.rpm
 
For LVM2-Cluster
lvm2-2.02.46-8.el5.x86_64.rpm
device-mapper-1.02.32-1.el5.i386.rpm    
device-mapper-event-1.02.32-1.el5.x86_64.rpm 
lvm2-cluster-2.02.46-8.el5.x86_64.rpm
device-mapper-1.02.32-1.el5.x86_64.rpm
 
But I fail starting dlm resource
 
primitive dlm ocf:pacemaker:controld \
        meta target-role= Started 
clone dlm-clone dlm \
        meta target-role= Started  interleave= true  ordered= true 
 
#crm_verify -LV

Any ideas are highly appreciated!
