Hi all, after some hours playing with RAID-1 recovery I wrote a tiny HOWTO-proposal, suitable mainly for newbies (I hope!). Please, comment it, send me all the corrections and flames, so it eventually can help constitute a needed section in the "real" HOWTO. The URL: http://www.chance.cz/~egon

There is no need for all this complication. At the start of the first disk create a small partition /boot which contains the kernel and lilo files (chain loader etc) i.e what is normally in /boot. Create a small linux installation (which can also be used as a rescue from a non bootable raid). Cr
