Migrating to new hardware
Change one or more NICs
Open a CLI and start the setup-wizard.
setup
First you have to remove the obsolete NICs before you are able to assign the new ones.
Change the mainboard
If you change you mainboard the sensor-chips will usually change too. So it is necessary to rescan for sensor-chips and remove obsolete rrd-files.
Rescan for sensors
/usr/sbin/sensors-detect
Follow the dialogue to generate a new configfile (/etc/sysconfig/lm_sensors).
To remove the obsolete sensors from the list of selectable sensors on the webif you have to remove the obsolete folders (sensors-*) from “/var/log/rrd/collectd/localhost” .
Important! You have to stop collectd before you change the rrd data, see below.
RRD-Graphs are wrong
Stop collectd:
/etc/init.d/collectd stop
You have to remove the “old” rrd-files within the folders “/var/log/rrd” and subfolders.
Now you have to start the “collectd”
/etc/init.d/collectd start
Finally a reboot is recommend.
