Root Label Problem - Kernel Panic
Hi,
I moved the RHEL4 from IDE to new SATA disk. I have labeled the new root and
swap partitions, but I cant get the system running. Just after initrd load
kernel panics:
mkrootdev: label /1 not found
Mounting root filesystem
mount: error 2 mouting ext3
switchroot: mount failed: 22
Kernel panic - not syncing: Attempted to kill init!
Why kernel can not find the label? What I did wrong?

Thanks for any help.
Sorry for my poor english.

Are you sure the label should be "/1" and not just "/"? The labels seem to
get appended with a number any time you move them.
Boot to a rescue cd and either fix the label or put the actual partition
name in your fstab (/dev/whatever it is) instead of the label.
