If you want to export multiple disk partitions from a single server, there
is a "cache file system" which is supported for use on the back end. There
is some information about this here:
http://xrootd.slac.stanford.edu/doc/mps_config/mps_config.htm
Unfortunately, I've not written any simple examples of that. (Note that
the documentation discusses a more general set of back end scripts to do
migration/purge of files staged from a MSS.)
Does this help with your problem?
(Note also that you can hide the details of the internal organization
on the server from the external clients with some of the other directives
like "localroot".)
