Hi debian-user list, In another thread here I am trying to help someone rescue an old broken system which GRUB is failing to boot.
That system has: - Legacy BIOS MBR (master boot record) boot ... (not EFI) - MSDOS partition table ... (not GUID partition table) - GRUB 2 i386-pc boot loader - /boot/grub files are loaded from Linux-raid RAID-1 filesystem But I lack information or experience of what a working GRUB MBR boot configuration on a RAID-1 system looks like. So I am asking the list for help. If you have a system with the same specifications (MBR boot on RAID-1) as above, I will be grateful if you could help me by doing a simple test on your machine: 1. Reboot it. 2. At the GRUB menu, press 'c' key to get a grub> command line. 3. At the grub> prompt, run the following commands, using the punctuation characters exactly as shown here: grub> set pager=1 grub> ls grub> echo $prefix grub> ls $prefix grub> echo $root grub> ls ($root)/ grub> echo $grubroot grub> ls ($grubroot)/ Please reply with the output that you see. I need all of the output from the first bare 'ls' command. But for the other 'ls' commands which have arguments, feel free to only show a representative fraction if their output, if it is too much to report. When finished, you can boot normally with the command: grub> reboot That will be helpful for me to see how a working system configures these values. Thanks!
