Just assembled a new Fedora 9 machine - md1-5 created OK, but am having
trouble putting md6 together - machine rebooted after partitioning):
[root@hugo2 ~]# mdadm -C /dev/md6 -l 1 -n 2 /dev/sda1 /dev/sdb1
mdadm: Cannot open /dev/sda1: No such device or address

[root@hugo2 ~]# fdisk /dev/sda
The number of cylinders for this disk is set to 121601.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
