perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Ah sorry, i sent you the wrong FAQ. I meant this: http://psps.perfsonar.net/toolkit/FAQs.html#Q29. I must have scrolled around while looking for it and not cleared my address bar.

It has pointer to a script already installed on your system. The other one does not do what you want (it's good to correct the link though). Sorry for the confusion.

Thanks,

Andy

I take it back, that links to the html. I don't know how to link to the raw file on google code.

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
