Hi again,
I'm cleaning my DB (which was 15GB) following:
https://github.com/puppetlabs/puppet-dashboard
I did:
rake RAILS_ENV=production reports:prune upto=1 unit=wk
rake RAILS_ENV=development reports:prune upto=1 unit=wk
(It has been running for about 3 months)
and after:
rake RAILS_ENV=production db:raw:optimize
rake RAILS_ENV=development db:raw:optimize
It has removed lots of entries, but it's still 15GB.
Am I doing something wrong? why is it not decreasing its size?
TIA,
Arnau
This is because the dashboard uses InnoDB tables. You'll probably have a
huge `ibdata` file in /var/lib/mysql/ somewhere. It's a known bug but
the `ibdata` file grows but doesn't shrink.

I'd suggest making MySQL use a different file per *.ibd file as it makes
it easier to see which table is the culprit. From there you should be
able to figure out a way to have the files re-created once you've pruned
them (albeit no "good" way that I know of).
