Not sure how grub handles it, but with LILO.... boot=/dev/md1 raid-extra-boot="/dev/sda,/dev/sdb" These two options will do what you need. Very strange.. Linux RAID auto-detect should automatically the partitions up from each device, so every time you reboot they become unsynced/not started? Justin. On Fri, 14 Jul 2006, Michael Menge wrote:

Also /dev/md0 -> boot /dev/md1 -> swap /dev/md2 -> root
Is the recommended config.
yast was able to install the other config an it did start, but after cloning the system it did not start. So Yast did something during installation so that the deviecs for /dev/md1 are found during boottime but i dont know what.

Hi,
I have clonend a System with tar and sfdisk and now i have Problems Booting the System. The Rootfs is on /dev/md1, Swap on /dev/md0
The last lines I see are the following
md: md1 stopped mdadm: no devices found for /dev/md1 Attempting manual resume md: md0 still in use md: md0 still in use mdadm: fail to stop array /dev/md0: Device or resource busy md: md1 stopped mdadm: no devices found for /dev/md1 md: md2 stopped mdadm: no devices found for /dev/md2 Waiting for device /dev/md1 to appear: ok rootfs: major=9 minor=1 devn=2305 /dev/md1: Unknown volume type Invalid root filesystem -- exiting to /bin/sh $
If i start /dev/md1 with mdadm -Ac partitions -m 1 /dev/md1 and exit the /bin/sh the bootingproces is continued, but this hase to be done every time i reboot.
I dont understand why the devieces for /dev/md1 are not found but the devices for /dev/md0 and why they are found on the original system.
