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 (locate at /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 must 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.
