[Jonathan Brassow <jbrassow@xxxxxxxxxx>]

You do not have the module installed (or in the right place?).

You need the cmirror and cmirror-kmod packages.  If you don't have  
access to them, and would like to compile them for yourself, then you  
will need to check-out the cluster tree on the RHEL5 or RHEL53 branch.
