Hi, I wrote about my ide-raid-1 crash (one hd was died). I have changed this hd and all works fine now (raid my love :) ) except lilo (lilo-0.21-15) which does not want to run. I have start with a floppy but need help to make it clean. any idea ? Octave # /sbin/lilo -v -v -v -v LILO version 21

Re: it should have arrived :/

will write just LI). I found out the problem: lilo has to be done in linear mode. So I have 2 ways: - start with floppy disk - or try to make lilo We made test on a server with lilo on /dev/hda down and it did not work. Any idea how to make lilo with /dev/hda died ? ;) PS sometimes it is good

it should have arrived :/

devices: Questions: - how can I see if hda is died or just it is an another error ? - what should I do ? reboot ? shutdown ? change hd right now ? wait ? help help ... Octave dmesg gives: Complete Error } hda: write_intr: error=0x10 { SectorIdNotFound }, LBAsect
