I posted this about a week ago on the rrd-users list, but got no response,
so I thought I'd try here... Forgive me if it's the wrong list, and if so,
please let me know where I can post it to get some help, as I am stumped...
We've been using rrdtool for a couple of years now in our MRTG graphs. At
some point, I upgraded from rrdtool 1.0.45 to 1.2.11.
Yesterday, we experienced a spanning tree loop which caused a large spike in
our graphs. I decided to attempt to remove the spikes this morning, using a
couple of tools (killspike.pl and removespikes.pl). I experienced a couple
Killspike.pl: after restoring the database from the xml file and rerun mrtg
against the .cfg file, I get the error: "ERROR: Cannot tune logfile: can't
handle RRD file version 0003".
Removespikes.pl: Unable to execute the rrdtool restore on
126.96.36.199_63.rrd - Inappropriate ioctl for device -
Hmm, I think. Something is fishy here. So, taking a hint from the mrtg doc
(mrtg-rrd.txt), I start checking my RRDp.pm. Lo and behold, the version in
my perl directories is different than the version in my rrdtool 1.2.11 build
tree. So, I save the old version and replace it with the new version. This
totally breaks MRTG's ability to process rrd files. I get the error "RRDs
object version 1.000451 does not match bootstrap parameter 1.2011 at
/usr/local/lib/perl5/5.8.0/i686-linux//DynaLoader.pm line 249."
So, finally, I replaced the RRDs.pm with the original one, and mrtg is back
up and running.
I know that I followed the rrdbuild.txt, as all of the other required
libraries are downloaded, uncompressed, untarred, and installed in the
Also, if I use the rrdtool executable from 1.0.45, I notice that the
<version></version> tag in the dump file is 0001, while the version in the
pathed rrdtool is 0003.
I guess my question is twofold:
a. Is my perl module incorrect?
b. If so, how do I fix this situation?
Thanks for any help anyone can give... I am totally lost at this point.
