Hello, i tried this howto. http://www.howtoforge.com/how-to-se...-system-incl-grub2-configuration-ubuntu-10.04 I also use Ubuntu 10.04(32). The difference ist that iam not having special /boot partition. /boot is located on / (/ is sda3, sda2 is /tmp and sda1 is swap) i processed this howto and every time where sdb1/md0 was used i replaced with sdb3/md2 Problem is rebooting, df -h (start of page3) dont shows md2 for /, it is still sda3 dont really find my mistake, fstab and mtab are edited as well. this is my /etc/grub.d/09_swraid1_setup root should be md2 in my case. #!/bin/sh exec tail -n +3 $0 # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. menuentry 'raid1 test 2.6.32-34-generic-pae ' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod raid insmod mdraid insmod ext2 set root='(md2)' linux /boot/vmlinuz-2.6.32-34-generic-pae root=/dev/md2 ro quiet initrd /boot/initrd.img-2.6.32-34-generic-pae } sda3 still on / blocks adding sda3 to my array md2. md0 and md1 works as expected. What could be my mistake? additional confs needed? Thanks for help, Hajo
What's in your /etc/fstab and /etc/mdadm/mdadm.conf? What are the outputs of Code: cat /proc/mdstat and Code: fdisk -l ?
Hello, thanks for your help. I did it again and this time it was successful. May be a small mistake at the first attempts. Thanks for the great Howto. Thanks, Hajo
Hello, just 1 short question. I changed partition type of my /tmp also to fd - Linux raid autodetect. Ist this needed or should better stay at 82 - Linux Swap / Solaris? Seems to work in both cases. Thanks, Hajo
thanks, i retained now as 82 - Linux Swap. At another test making a raid1 i had again my initial problem. System was not booting from md2, it still uses sda3 for startup. Again i did not find any problem in my files. Now i changed: update-initramfs -u to: update-initramfs -u -k all as mentioned in other readmes and it worked. This could be the mistake? I dont really know... Hajo
