Installed a new drive for my Software RAID1 in Linux but I cannot install grub on it
Hello everyone,
I am using Ubuntu 8.04 (32bit) and I am running a RAID1 array (sda,sdb).
Anyway, I replaced /dev/sdb and created bigger partitions, the array was built and in sync after a few hours.
Now, I tried to install grub as I read in the documentation and also tested this in a VM to simulate the RAID1 disk replacement.
grub> root (hd1,0)
grub> setup (hd1)
In the documentation and on my tests this worked like a charm but on the real physical server I get "Error 15".
It cannot find the stage1 in my server, so I tried grub-install and it worked with no errors but after running the bootscriptsinfo,
I can see grub1 is installed in /dev/sdb but will try to boot from hd0 which is not good for me as I want to replace also /dev/sda (hd0).
I have no idea why this didn't work for the real server.
Any help appreciated, I haven't rebooted the server as it is working as a file server and I don't know if it is going to come up, so this weekend I am going to backup /home and reboot it. I also have the old hard drive, so I believe at any point I can actually boot from it and copy over the backup.
Here is my bootscriptsinfo.
