Re: RAID 1 HELP!!!

[Agustín Ciciliani <agustin@maderonet.net.ar>]

Dear Lucas,

I tried with linear and my debian just boot! I'm sending to you my lilo.conf file (in case
it seems to you useful for your how-to with LILO) after making some changes that
"lilo-doc" recommended for raid booting.

As I thought it couldn't be the only problem... Could you take a look to the following?
Note: Not all the devices are synchronized at this time. Sorry about this (It takes 7
hours each time I have to do it again...). Perhaps I just have to wait???

Thanks for everything!!!

Agustín
