Hi all,<br><br>I've been testing out collected on one system for a few months, and just installed it onto a "pre-production server" I'm working on today. (CentOS 4.2 x86_64, sempron3300+ /64bit with 1gig ram, mirrored 250gb SATA HDDs)
<br><br>An odd thing: Collectd appears to be working fine, but as long as it is running, I get these messages thrown to /var/log/messages on approximately 2 minute increments:<br><br>Mar 21 16:03:20 docs collectd: cpufreq found 1 cpu(s)
<br><span style="font-style: italic;">Mar 21 16:03:53 docs kernel: SCSI error : <0 0 0 0> return code = 0x8000002</span><br style="font-style: italic;"><span style="font-style: italic;">Mar 21 16:03:53 docs kernel: Invalid sda: sense key No Sense
</span><br style="font-style: italic;"><span style="font-style: italic;">Mar 21 16:03:53 docs kernel: Additional sense: Filemark detected</span><br><br>If I stop the collectd daemon, the messages stop piling up. If I restart the daemon, the messages resume. Hence my belief they are related.
<br><br>I Suspect ? it relates to how Collectd is polling for information from the drives, possibly the fact that SATA drives are seen to the system as /dev/sd devices, and somehow? collectd may be assuming they are scsi devices, treating them with commands that aren't working correctly? However, I'm not positive (alas) what this really is.
<br><br>Any thoughts / comments on how to resolve this would certainly be appreciated.<br><br>Many thanks,<br><br>Tim<br><br><br>[ps - I'm running the collectd as per the pre-compiled RPM binary for RHEL 4 64bit, ie, the URL this was obtained from was
