Put "echo" before rrdtool, to see exactly what command is being generated without actually trying to execute it. Then you can tinker with it till it looks right and then remove the echo to try it for real. But also, it might depend on your CSV file. If you post a few example lines we might be able to help. Also post the definition of your RRD file.
