Hello Richard,
I have not try this before (because I need plain-text collectd log files, not rrd ones), but I have now and it didn't help, I still get:
"No write callback has been registered. Please load at least one output plugin, if you want the collected data to be stored."
The files I'm looking for are, for example (this is from another system):
$ head /opt/collectd/var/lib/collectd/cpu-0/cpu-user-2012-04-20
epoch,value
1334880003,7.700000
1334880013,2.000000
1334880023,0.300000
Thanks,
Otis

Have you tried adding LoadPlugin rrdtool, so that it will make rrd files?
