Two-cent tip: GRUB and inode sizes

Hello!

I had a decent fight with a stubborn server today. It was a Fedora Core 6 system (let's not talk about how old it is) that was scheduled for a change of disks. This is fairly straightforward - until you have to write the boot block. Unfortunately I prepared the new disks before copying the files. As soon as I wanted to install GRUB 0.97 it told me that it could not read the stage1 file. The problem is that GRUB only deals with 128-byte inodes. The prepared / partition has 256-byte inodes. So make sure to use

mkfs.ext3 -I 128 /dev/sda1

when preparing disks intended to co-exist with GRUB. I know this is old news, but I never encountered this problem before. https://www.linuxplanet.com/linuxplanet/tutorials/6480/2/ has more hints ready.

Best, René, who is thinking about moving back to LILO.

+1 for Debian here then, who manages to get this right off the bat.

Never thought about that before. Thanks for the tip!
