Hi everyone,
Here is a link to information about using the dCache GIP plugin that Derek
wrote. This is the one that does the `du` on /pnfs and puts the actual
per-VO usage into the information system.
http://www.gridpp.ac.uk/wiki/GridPP_dCache_GIP_plugin
RAL-PPD already use it and Chris hasn't observed any problems with running
the cron job every hour (correct Chris?). I think we will discuss whether
all sites should use this plugin (or not) at the next storage meeting.
Let us know how you get on if you try it out.
Cheers,
Greig
