Nope.

You may want to look at the "rrdjig" tool also, if you are increasing 
the number of data points you keep in each RRD. The normal rrdtool 
"resize" command has some interesting "side effects"; e.g. if you 
increase the number of 5-minute-average datapoints from 2 days to e.g. 7 
days and then try to view a graph showing between 2 and 7 days, then 
initially the graph will only show data for the last 2 days - because 
even though you resized the dataset in the RRD, it didn't populate the 
dataset with any data! rrdjig tries to do better than that.
