Okay. > Again my thinking is because > md? exist as virtual devices in dev fdisk tries to determine the partition > type and fails but can read the individual partitions on the real disks > themselves sd?. Just a guess. It's a good guess, and I'm honestly not sure. One way of using fdisk is to pass it a device to operate on, like 'fdisk /dev/sda', in which case it should only read the partition table on the one device. 'fdisk -l' is a special case where you're trying to list all the partition tables on devices that can have partitions. What I'm not sure of is where it gets this list of devices from. If I had time, I'd get "apt-get source util-linux" to get the code for the fdisk command, and examine how it's done in the code. I can understand how fdisk can be confused, though; /dev/md0 is a "device" that contains more than one device that has a partition table, so there's no way to list the "one" partition table for that virtual device. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Nov 3 - Open Source Hardware: Bugs, Beagles and Beyond Dec 1 - IBM's Open Client Deployment Jan 5 - Building a Comunity Site with Drupal
