Updating rrd's structure

[Nexus_man]

Is it possible to update rrd's from cacti ? Because cacti's in datasources view debugger show that my rrd has 5 rd's, but rrdtool info says there are onyl 1. Samething is happening when i try to make a grahp out of the same rrd, "no DS called 'xxx....' in 'xxxxx.rrd'.

Should i just manually destroy the rrd's and create them again from the datasource management window ?

Update i just deleted the rrd's and created them again, now it works :)
