Editing Ceph Storage Cluster (section)

===== Mount Helper =====
All you need is the 'mount.ceph' executable, but there is no way to just get that file.  So, you have to load the ceph common application bundle, which results in a bunch of dependencies that nobody will ever need:

 sudo yum install -y ceph-common

Obviously, you will need to set up the repository as described above depending on your OS ... and specifically the instructions for using the 'updates-testing' repository on Fedora if needed.
