Kernel panic when booting off SATA clone in Red Hat Enterprise Linux 4

Solution Unverified - Updated -

Issue

  • RHEL4 installed from CD onto PATA (IDE) drive. This PATA drive was then cloned onto an SATA SSD using the 'dd' command ( dd if=/dev/hda of=/dev/sda bs=4096 ). Changed references from 'hda' to 'sda' in grub.conf and device.map on the SATA drive. Verified there are no references to hard drive as 'hda' in fstab.

  • Disconnected PATA drive, connected only the SATA drive to the system. Attempted to boot from SATA drive, with the following result:

    "Uncompressing...booting kernel 
... 
No volume groups found 
Unable to find volume group VolGroup00 
ERROR: /bin/lvm exited abnormally (pid 429) 
... 
Kernel panic: not syncing: Attempted to kill init."

  • RHEL was not directly installed on the SATA drive because the installation process did not find the drive

  • It did install on a PATA drive, so we tried cloning. 

Environment

  • Red Hat Enterprise Linux (RHEL) 4
