Thanks for your answer... Out of curiousity, why do you use /dev/zero? Would dd to /dev/null cause problems or is /dev/zero required for proper results? >Hi, > >/proc/mdstat is to monitor the status of your raid, so when one drive >fails it >becomes dropped out of the raid-array. Using mdadm you can monitor >/proc/mdstat and it even can send you a mail when one of your disks fails. >So >if you really want to scan your disk once a week, why not running 'dd >if=/dev/mdX of=/dev/zero' ?
