CentOS CPU Temperature - Mini-HowTo
by Seth Bardash 12 Feb '05

12 Feb '05

Ok, Way too many requests. SO..... here's my Mini How-To. Use of this is at your own risk, Blah Blah Blah legal disclaimer applies..... ;-) Download from either: http://secure.netroedge.com/~lm78/ or http://www.integratedsolutions.org/downloads/i2c-2.8.7.tar.gz http://www.integratedsolutions.org/downloads/i2c-2.9.0.1.patch http://www.integratedsolutions.org/downloads/i2c-2.9.0.tar.gz http://www.integratedsolutions.org/downloads/lm_sensors-2.8.7.tar.gz http://www.integratedsolutions.org/downloads/lm_sensors-2.9.0.tar.gz WARNING: We have not finished testing 2.9.0 and there seems to be a few bugs there. So we recommend downloading the 2.8.7 files above.... NEXT: un-tar.gz the files to directories in home go to your kernel source directory: edit Makefile to read the same as the installed kernel (uname -r) (delete the word "custom" at the end of the line: EXTRAVERSION = -27.0.2.Elcustom) run make mrproper run make oldconfig run make dep run make clean The above sets up the kernel source so you can build and install the i2c and lm sensors drivers correctly. cd to i2c directory under /home run make clean run make all run make install cd to lm sensors directory under /home run make clean run make all run make install do an extra depmod -a (just in case :) ) ignore any unresolved symbols messages if you get them run sensors-detect and read the outputs carefully test the lines that the sensors-detect script tells you to add to rc.local one at a time to make sure the appropriate drivers load successfully. If they do you're all set. Next: Just add the lines required to /etc/modules.conf and /etc/rc.d/rc.local and reboot. Your i2c and lm sensors stuff will start at power up. You can test the output with the sensors command. You might want to look in the /home/lmsensors ( cd /home; find . -name "sensors*.*" ) directories for the newer sensors.conf file and copy it to /etc. Modify the new one to give you the output you want. Here is a script that we use when doing burn-in on our systems to monitor the time they have been running and the latest temps - we test under full load using cpuburn-1.4. #! /bin/csh # temp display shell script # ISSLLC sab 3/04 echo "" echo "Starting" echo "" @ counter_s = 0 @ minutes = 0 @ hrs = 0 echo "Burn Time = $hrs hrs $minutes mins $counter_s secs" echo "" while (1) sensors | grep emp sleep 10 echo "" @ counter_s += 10 if($counter_s == 60) then @ counter_s = 0 @ minutes += 1 if($minutes == 60) then @ minutes = 0 @ hrs += 1 endif endif echo "Burn Time = $hrs hrs $minutes mins $counter_s secs" end echo "I'm Done..." After its all working properly, have a drink and say "thanks Integrated Solutions" ;-) Let me know if this was helpful.

CPU temperature?
by Johnn Tan 11 Feb '05

11 Feb '05

Has anyone gotten lm_sensors to work on a CentOS3.3/RHEL3 box? I think I'm having CPU temperature-related problems, and wanted some way to monitor it. I believe lm_sensors does this, but can't seem to figure out how to get it to work. I already did "yum install lm_sensors" but when I run sensors-detect, it complains: Couldn't open /proc/bus/i2c?!? at /usr/sbin/sensors-detect line 2970, <STDIN> line 3. I googled around, but there appear to be more questions than answers. I'd appreciate any help. FYI, this CentOS3.3 server is remotely managed.managed. johnn

Ken, Importing the key fixed my problem. Thank you. I adjust the comp time, hopefully I will no longer be coming back from to the future. Thanks again.

GPG Sig Error with CUPS
by Ed Morrison 11 Feb '05

11 Feb '05

Hi Everyone, Sorry to post right out of the gate but I'm having problems running yum upgrade on a new centos 3.4 install. I performed a minimal install of centos, this means I did a custom install but unchecked everything including cups. Error tells me to clean or rm the file...tried both to no avail. Anyone else run into this issue? How do I get beyond it? The exact error is: Downloading Packages warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 025e513b Error: Could not find the GPG Key necessary to validate pkg /var/cache/yum/update/packages/cups-1.1.17-13.3.24.i386.rpm Error: You may want to run yum clean or remove the file: /var/cache/yum/update/packages/cups-1.1.17-13.3.24.i386.rpm Error: You may also check that you have the correct GPG keys installed Thank you for your assistance. Ed

SATA Raid - final
by Nigel Kendrick 11 Feb '05

11 Feb '05

Thanks for all the advice on setting up software RAID with SATA drives - especially to Morten Tormoen for the information on speeding up the re-sync. I have now had time to go back to the machine and start again: I now have one 300GB SATA drive on the motherboard controller and one on the PCI card and they're currently re-syncing at 48445K/Sec and will be done in 90 mins - a big improvement on 250kB/sec!!!
