Converting RRDs - 32-bit to 64-bit architecture migration

When migrating from 32-bit to 64-bit architecture, note that the 32-bit RRDs are incompatible and need to be converted to the new architecture. This can be accomplished by converting the RRDs to XML format using the 32-bit RRDTool binary and restoring the XML file using the 64-bit architecture RRDTool binary.

• On the 32-bit architecture:

  mkdir -p /tmp/rrd
  cd /usr/local/groundwork/rrd
  for i in *.rrd; do /usr/local/groundwork/common/bin/rrdtool dump ${i} /tmp/rrd/${i}.xml; done
  tar czf /tmp/rrd.dumps.tgz /tmp/rrd/*.xml
  

  • Then copy the tgz of the xml files over to the 64-bit system
• On the 64 bit architecture:

  tar xzf rrd.dumps.tgz -C /
  cd /tmp/rrd
  for i in *.xml; do /usr/local/groundwork/common/bin/rrdtool restore -f ${i} /usr/local/groundwork/rrd/${i%.xml}; done
  chown -R nagios.nagios /usr/local/groundwork/rrd
  chmod -R 644           /usr/local/groundwork/rrd
  rm -Rf /tmp/rrd
