Wasn't making a server also a client considered bad juju ?  Memory pressure things and panics and other badness.   This would be nice because the OSS's have the biggest network pipes in our setup.   BTW I am moving old files from old OST's to new OST's to balance them back out.  in usage and in age distribution.
