"Cluster Storage" group not visible in "yum grouplist"

Environment

• System registered to Red Hat Network

Issue

• "Cluster Storage" group not visible in "yum groupinstall" or "yum grouplist"

# yum groupinstall 'Cluster Storage'

Setting up Group Process
Warning: Group Cluster Storage does not exist.
No packages in any requested group available to install or update
# yum grouplist | grep -i cluster
   Clustering
# 

Resolution

• As a workaround, use yum to install the individual package names:

    # yum install Global_File_System-en-US gfs gfs-utils gnbd kmod-gfs kmod-gfs-kdump kmod-gnbd kmod-gnbd-kdump lvm2-cluster
  

Root Cause

• The comps.xml file pulled down from Red Hat Network is not for Cluster Storage. It is identical to the Clustering channel's comps.xml.

Diagnostic Steps

Check if the comps.xml files are the same.

# ls -l /var/cache/yum/rhel-x86_64-server-cluster-5/comps.xml /var/cache/yum/rhel-x86_64-server-cluster-storage-5/comps.xml

-rw-r--r-- 1 root root 106022 Oct 24 08:22 /var/cache/yum/rhel-x86_64-server-cluster-storage-5/comps.xml
