hello list, my system is a Debian GNU Linux Sarge. The kernelversion is 2.6.10 without modulsupport. The partion id is fd. In the first step, the complete system is installed on /dev/hda3. In the second step, i have created a raid 1 device: mdadm --create /dev/md0 --level 1 --raid-device=2 /dev/hda1 /dev/hdc1 mkfs -t ext3 /dev/md0 mount /dev/md0 /mnt cp -pr /boot /mnt umount /mnt I want to mount /dev/md0 in /boot change in the /etc/fstab /dev/md0 /boot ext3 defaults 0 2 after a reboot, i see the mounted devices: /dev/hda3 on / type ext3 (rw,errors=remount-ro) /dev/md0 on /boot type ext3 (rw) so, i think i will never need the files in the old /boot directory. umount /boot cd /boot ls System.map-2.6.8-1-386 config-2.6.8-1-386 vmlinuz-2.6.10 grub vmlinuz-2.6.10-raid-grsec initrd.img-2.6.8-1-386 vmlinuz-2.6.10-raid-grsec-hotplug lost+found vmlinuz-2.6.8-1-386 System.map-2.6.10 rm -r * cd .. mount /boot ls /boot System.map-2.6.8-1-386 config-2.6.8-1-386 vmlinuz-2.6.10 grub vmlinuz-2.6.10-raid-grsec initrd.img-2.6.8-1-386 vmlinuz-2.6.10-raid-grsec-hotplug lost+found vmlinuz-2.6.8-1-386 System.map-2.6.10 after a reboot, i see the following message from Grub: GRUB Loading Stage1.5 GRUB loading, please wait ... Error 15 Ok, i think GRUB can`t access to /dev/md0 what can i do?
