Red Hat Knowledgebase

Use the following steps to install the failover cluster or load balancing Cluster Suite packages:

1. Register your cluster nodes with the Red Hat Network (RHN) and add the Cluster Suite child channel to all cluster nodes. See additional Knowledgebase articles on how to add child channels in RHN.
2. Apply all available errata for your system (update your system using up2date).

3. Determine what type of kernel you are using with the possible choices being the uniprocessor kernel, the SMP kernel, or the Hugemem kernel. You can determine this by running the command uname -r. This will print the kernel version, with an identifier at the end. You will notice EL if its an uniprocessor kernel, ELsmp if it is the SMP kernel, or ELhugemem if it is the hugemem kernel. For example:

   $ uname -r 2.6.9-16.EL

4. For a failover cluster (with shared storage) install the following packages using up2date. This is where your kernel type is important. If you are running the SMP or Hugemem kernel, you will need to add -smp or -hugemem, respectively, to the end of any package name that ends in -kernel. So, for example if you are running the SMP kernel, instead of installing cman-kernel, you will install cman-kernel-smp. This is a list of the packages you need to install:

   • cman, cman-kernel
   • ccs
   • magma, magma-plugins
   • dlm, dlm-kernel
   • rgmanager
   • lvm2-cluster, only if you are going to use CLVM
   • system-config-cluster

   up2date cman cman-kernel dlm dlm-kernel magma magma-plugins system-config-cluster rgmanager ccs lvm2-cluster

   For an SMP kernel:

   up2date cman cman-kernel-smp dlm dlm-kernel-smp magma magma-plugins system-config-cluster rgmanager ccs lvm2-cluster

5. For a load balancing (LVS) cluster, use up2date to install the piranha-gui package. This will pull in several other packages as dependencies necessary to complete the install.

   up2date piranha-gui

Use the following documentation to assist with configuring and managing Cluster Suite:
