You can change it in "rrddefinitions.cfg", but it will not change
any existing files - only newly created ones.
OK, thanks. That's what I was wondering - is there anything still
compiled in? I guess that's a "not any more".
Nope.
I've thrown together a script to resize the existing RRD files, seems to
work OK. It just gets the RRA list from "rrdtool info", then loops
through resizing one at a time. I'd post the script, but it's at work
and I'm not... :-) If anyone is interested, it shouldn't take too
long to re-invent.
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.
