[rrd-users] RRD error - min must be less than max in DS definition

[Steffen.Pelzetter at nexans.com]

Hello,
I use rrd on my debain 3.1 sarge alpha port to run hobbit monitor.
The installed version  1.2.10.

All was running I don't now exactly when, but I've changed the kernel to 
2.6.8
and installed some security updates and the rrd graphs stop working.

Therefore I had a look into the log- files rrd-status and rrd-data log.

These lines are logged repeatly:


in must be less than max in DS definition

/usr/local/hobbit/data/rrd/wva-sv0012/disk,X.rrd: min must be less than 
max in DS definition


for every datasource I've installed.

I've reported the problem to hobbit. They ask me to put --debug on and use 
data in the debug log to maually
run rrdtool from command line.

Here is the result:

./rrdtool create /tmp/tcp.orarns.tcp 'DS:sec:GAUGE:600:0:U' 
'RRA:AVERAGE:0.5:1:576'
ERROR: min must be less than max in DS definition

Next I've tried to re- compile and install rrd.

If I try to ./configure I get an error- message:

I've used gcc 4.1.1 and I don't understand the problem because gcc accepts
the -mieee switch:


What can I do?
