Question #219015 on Graphite changed:
https://answers.launchpad.net/graphite/+question/219015

    Status: Open => Answered

Nicholas Leskiw proposed the following answer:
If you started sending metrics before setting up your schemas, the
metrics have already been created with a different retention rate.
Check the .wsp files with whisper-info.py to make sure the retention
rate is correct. If not, you can either resize the with whisper-
resize.py or erase them and start from scratch.
