raid1 mount:/dev/md0: can't read superblock
I have an AMD64 motherboard with one pata drive that contains the whole installation including data and two identical 500G sata drive that were set up as raid1 for experimentation, then I had to reinstall for some reason.
If my recollection is correct, the first raid1 was made after the install and worked, I used it only to 'archive" /home but the second was done during the install, seemed OK but does not work.
When I try 'archive' under Debian Lenny with the GUI, I get the message mentioned above.
There are a few howto on the internet but none that I can follow from start to finish without improvising at some stage.
Can anyone suggest which howto to follow in my case and if this is the one that is part of the install, how to do that without reinstalling everything else.
Thank you for your help.
