The link in the FAQ is wrong:

I think it should probably be this:

Hi,

We have a script that can help with that. See http://psps.perfsonar.net/toolkit/FAQs.html#Q60 for examples. The examples will mysql dump the old data to files and then delete it from the database. If you don't care about saving dumps of the data you can drop the --mysqldump-opts and --dumpdir options, and replace them with --no-save-dumps See the --help of that script for a full listing of options.

Thanks,
Andy
