Hi Brian,you use "rrdtool dump <filename>.rrd <filename>.xml" to dump the contents of the RRD <filename>.rrd to the XML file <filename>.xml. Execute this for all RRDs on the old machine, and copy the .xml-files to the new one. Then, with "rrdtool restore <filename>.xml <filename>.rrd" rebuild the RRDs from the XMLs on the new machine.

Having never used rrdtool. Other than for hobbit, how do I go about dumping and restoring? And yes it was architecture change from a dell 2850, to a VM. I think I also updated the version of rrdtool.I still have the old server so can do this from the console.

Hi,another possible reason could be different versions of RRDTool (which can also be solved by dumping and restoring the RRDs, as suggested by Buchan).hh Buchan Milne schrieb:On Tuesday 07 April 2009 14:05:39 Brian O'Mahony wrote:I moved from rhel3 to a rhel5 machineAre there any other differences? E.g., i386 vs x86_64 ?I'm guessing the architectures differ, and you didn't dump/reload the rrd files (which is required if you change architectures, e.g. i386 to x86_64)., as I was moving everything else on the box also. I recompiled hobbit (4.2.0) on the machine, and just copied over the files. However the graphs and graph history are missing. I moved the /home/hobbit directory and installed a fresh copy -- graphs are visibl;e.Regards, Buchan To unsubscribe from the hobbit list, send an e-mail to hobbit-unsubscribe (at) hswn.dk
