One of my final tasks in this current job was to get our 6-node Linux development cluster up and running again. I’d hoped it would be a case of simply switching it on…but no. A variety of bizarre lilo errors on several nodes including “invalid compressed format (err=1)” and something about something else being too big and overlapping. WTF?
Knoppix to the rescue. Boot up, mount the root partition, bring up eth0 if required, scp a working /boot/grub from another machine, edit menu.lst to suit. Then “root (hd0,0)”, “setup (hd0)”, “quit”, logout of Knoppix and reboot. Voilà.
Knoppix is a life-saver and just one of the best things ever in Linux world.
