You may to pull apart your initrd image and look at your init script (or whatever your startup script is called) to see how it is assembling your arrays. If you're using user space to assemble your arrays at boot time (i.e. mdadm via initrd) it is most likely using the mdadm.conf file located in the initrd. Typically, mkinitrd is called when a new kernel is installed. The mkinitrd script will grab the necessary files (i.e. mdadm.conf) needed to mount the root filesystem. I'm not sure I've seen a system auto assemble an array when the partitions were not set to 0xfd. My bet is that you have a mdadm.conf file in your initrd and that the init script is starting the array in user space via mdadm. Though, I could be wrong :-) Bryan -- 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
