Question #205309 on Graphite changed:
https://answers.launchpad.net/graphite/+question/205309

    Status: Open => Answered

Nicholas Leskiw proposed the following answer:
Retentions only applies to new files.  For existing metrics, you must
either use the whisper-resize.py utility that comes with whisper or
erase the files and allow Carbon to re-create them.
