I have debian squeeze webserver and each week I receive an email with error:

Subject: Cron if [ -x /usr/share/mdadm/checkarray ] && [ $(date +%d) -le 7 ]; then /usr/share/mdadm/checkarray --cron --all --idle --quiet; fi (failed)

Mail: checkarray: E: MD subsystem not loaded, or /proc unavailable.

Any ideas what could be causing this?

I found this although what is it I need to remove? http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=616688

I have just checked all of my crons and cant find anywhere "mdadm" is mentioned? –  John Magnolia Dec 7 '12 at 8:20

This is happening because you have the mdadm package installed, but no md arrays (software RAID arrays) configured.

The mdadm crontab script is in /etc/cron.d/mdadm

If you remove the mdadm package, it will stop the error occuring.
