I guess what set the alarm off was getting what looked like a rebuild to me while stress testing. Yes, I'm running Debian and I have exactly this entry in my crontab...

Or maybe I should just RTFC (read the fine crontab) ;-) Oliver - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
