Subject: Request for help, if you have a working RAID-1 system with GRUB MBR boot

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!
