"kernel panic" on sata hard disk
Hello All!
I have a Red Hat running on an IDE hard disk. I needed to put it to work on a Serial Ata so I decided to do a full copy of it using the dd utility, something like this: dd if=/dev/hda of=/dev/sda The copy was done successfully, but When I tried to boot the new system with Serial Ata I got this message: Creating block devices VFS: Cannot open root device "LABEL=/" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 00:00 Since I've done the copy I didnīt do any changes, should I modify something?? Thank You!!! Rodrigo |
first make sure you got the label right on your sata. second you motherboard might confuse you linux (I had the same problem). Simply put the drive order might not be the same for linux hence linux is looking on the wrong drive. Third a site that I found usefull to solve my problem http://bembelbee.wordpress.com/2005/...fective-files/

Hey dunkert, thank you!!!
I'm going to do the copy again, the site you've suggested seems to be very good (it's what I was looking for), if I can make it work I tell you :) Thank You again!! Rodrigo |
You do not want to use the dd to do the copying unless the disks are identical you should get a Knoppix boot CD boot with it and setup your partitions, format them then copy over the files.
Edit: I would add if you need instructions on doing this search on my posts I described the process in detail a few weeks ago. |
