Do you happen to know if this bug was present in ubuntu 11.10, kernel versions 3.0.0-15-server or 3.0.0-16-server ? I saw failures to assemble RAID6 arrays after unclean shutdowns on both of these, just in test environments. If it happens again I'll send mdadm --examine output. I just tried to replicate it and failed :-( Regards, Brian. -- 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
