Don't forget to read that fine manual on "rrdtool resize" !
http://oss.oetiker.ch/rrdtool/doc/rrdresize.en.html

Do not increase the amount of rows significantly in one go.  Do this
bit by bit, or else you will see NaN a lot when you query data that
is available in other RRAs, but rrdtool selects the 5-minute RRA as
a best match. Think about this for a while if you don't get it at
first.
