It's a long story, the thing is quite ugly and messy and does messy things too, but they says it's compatibility stuff and continue shipping it. For the OP, the solution is to *create* mdadm.conf file - in that case mdrun should hopefully NOT run. /mjt - 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
