How can I get this info? All I get dmesg and messages logs after the 
boot. Is there a log somewhere? If not, I think I have to watch the 
monitor on the server during boot.

The problem is there is a raid card kernel module loads during boot. If 
I boot the rescue disk, /mnt/raid will not be mounted.

You are absolutely right. I am just trying to do my best to recover 
whatever I can.

Thank you.
