cluster configuration cman

[nasmel]

i am configuring a 2 node cluster using RHCS.i was successfull in installing the cluster with GULM lock server,but i want it to change to DLM.I tried to do that
from tool menu by clicking change to DLM and by clicking on Send to cluster,at that tie am getting an error message like

"A problem was encountered when attempting to get information about the nodes in the cluster:/sbin/cman_tool:cant open /proc/cluster/nodes, cman not runnuing"

I tried to start cman service but it also fails

#rpm -ivh cman*
failed dependencies

/lib/modules/2.6.9-42.EL is needed by cman kernel-2.6.9-45.2.i686

similar entries for caman-kernel-hugemem and cman-kernel-smp

#rpm -ivh cman* --nodeps
says that all the packages are installed


i have already installed the Kernel
2.6.9-45.0.10.ELsmp

#uname -a
Linux xxx.xxx 2.6.9-42.0.10.ELsmp #1 SMP Fri ...i686 i686 i386 GNU/Linux


wat to do next,how to reinstall or

The cman package is depending of a kernel version older than you have installed. Download the kernel version requiered for cman (2.6.9-42.EL).

Then remove /etc/cluster/cluster.conf in both nodes and run system-config-cluster again.
