Digimer, 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. -Param On Fri, Aug 24, 2012 at 9:06 PM, PARAM KRISH <mkpa...@gmail.com> wrote: > Please find below the details. > > 1. cluster.conf : Please find attached herewith. > > 2.
