[Deploying Sakai] [Building Sakai] deprecating a bodyVolume

You're right, John.  You can just remove the old volume name from the list of bodyVolumes.  The result is that no new resources will be stored there, but existing body content stored there will still be available.  If someone takes advantage of the "replace with new version" action in the resources tool, the new body content would replace the existing body content in the old volume, but otherwise new content would be distributed to locations on the new volumes.

You do not want to let the volume fill up.  That can lead to errors and lost files.  Some tools report the errors to users, and others seem to fail silently.  Some JIRA tickets have been created to deal with the tools in which that fails silently.
