If feasable, dump the database to ascii format and check. The structure of an RRD file is quite simple. It should not be too hard to check this. > I've already tried deleting them and they're either getting re-corrupted, or > I don't understand what's going on -- Some of the other .rrd's created by > the same process are fine, while several (maybe .1%) of them give me this > error. The RRD in question has very little data in it, but usually RRDTool > just returns a NaN if I ask for something that isn't there, right? This is not correct. If RRDtool gives you NaN values, it is simply returning data that *is* there. The data just is NaN. Of course somebody will correct me if I'm wrong on this. > The error is: > RRD ERROR: fetching cdp from rra I'm not entirely sure but it seems that you are asking for an entry that is not in any RRA. If you have created the dump, you can easely check this; all available intervals are shown. > The @graphOpts variables are: [snip] > -s -2000m Is this perhaps a RRD that has no RRA which stores upto 2000 minutes ? Or maybe the 'm' is mistaken to mean months? (just try it by specifying 'min' in stead of 'm').
