What I'm currently doing is creating wrapper scripts that check to see
if the clustered filesystem is mounted, then if it does, execute the
job.  This script is then placed in crontab.

The downside is that I have to update the crontab on all cluster nodes,
as well as copy the wrapper script to each node.


I've been toying with the idea of making an rgmanager aware cron, but
haven't worked out enough details of how it would work to write
something up for comments.
