For safety's sake, I'd be inclined to create C.rrd with the same RRAs and DEFs, etc. as A and B, then do rrdtool fetch A.rrd --start <whenever> >C.data rrdtool fetch B.rrd --start <whenever> >>C.data and hack C.data into a form suitable to be used with rrdtool update. Once convinced C.rrd is sane, you could then do a last transition and either rename C.rrd as B.rdd (or A.rrd), or switch to writing to C.rrd direct. __________________________________________________ Do you Yahoo!?
