Hi John
I think the only documentation is the man pages
http://grid-deployment.web.cern.ch/grid-deployment/documentation/LFC_DPM/dpm/man1/dpm-modifyfs.1.html
for dpm-modifyfs it only tells you
weight:
specifies the weight of the filesystem. This is used during the filesystem selection. The value must be positive. It is recommended to use a value lower than 10.
but then the page for dpm-buildfsv
http://grid-deployment.web.cern.ch/grid-deployment/documentation/LFC_DPM/dpm/man1/dpm-buildfsv.1.html
gives you a bit more idea of what will happen if you use different values.
I don't think we have much experience of what will happen in practise except for a very quick test with JP when he was developing. Some experience in production would be very interesting to hear about!
Cheers
Wahid
