I just want to confirm if i am missing any rpm's in my setup.
I referred this site http://www.centos.org/docs/4/html/rh-cs-en-4/ap-rhcs-sw-inst-cust.html to install the rpm's in red hat 5.6 but these packages magma*, dlm* are missing in the CD, does it mean these are really important ? I installed using 'yum group install' for "Cluster" and "ClusterStorage"
This is what the yum.log says from server1. Please confirm if there is something missing.

Please find below the details.1. cluster.conf : Please find attached herewith.2. Is fencing in any form mandatory for a setup as simple as this ? I am just using two redhat5 VM's within VMware fusion in my Mac. What kind of fencing is applicable to this kind of setup, that can also benefit me ? All that i want to see from this PoC is to add some services like Apache, MySQL to see how quick and reliable the cluster to pick the service failures etc.,3. Please find attached the messages from server1 and server2 when i did "service cman stop and start" on both nodes one after the other. In server1 both stop and start went fine but clustat showed "Could not connect to CMAN: connection refused". If i do "cman_tool join" on both nodes one after the other, things look greenAlso, Am i missing any rpm's that are most important ? I used yum group install "Clustering" and "ClusterStorage" to install all the packages.-ParamOn Fri, Aug 24, 2012 at 7:28 PM, Digimer <lists@xxxxxxxxxx> wrote:A few things;
1. Please repost your cluster.conf file with line wraps in plain text.
2. Manual fencing is not supported in any way, please use real fencing,
like IPMI, iLO, etc.
3. Please stop the cluster entirely, start 'tail -f -n 0
/var/log/messages' on both nodes, then start cman, then start rgmanager.
Please share the output from the logs.
