Performance Graphs not Populating (not all servers)

@blariv, The problem is that RRD files are unable to accept a dynamic increase of data sources. For example, if the number of partitions on the disk increases/changes the RRD will likely get corrupted and you will see this message.

found extra data on update argument

We do have the solution that you can use to fix RRD files when the number of data sources increases.

But to answer your question, we don't have anything in place that can automatically delete RRD files if there is a problem. Also, deleting RRD is not always the best solution because It deletes graph history. If a graph was collecting data for 1 year you will lose 1 year of data by deleting the RRD.
