Moving hard drive with RHEL 4 from one machine to another.

[thephilly]

Machines are similar hardware, moving from newer box (compA) to slightly older (compB). Both machines are single SATA drives. Pulled cover from compA, removed drive, replaced into compB.

When booting I get this error:
Booting 'Red Hat Enterprise Linux ES (2.6.9-67.ELsmp)'

root(hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.9-67.ELsmp ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.9-67.ELsmp.img

Uncompressing Linux… Ok, booting the kernel.
Red Hat nash version 4.2.1.13 starting
Reading all physical volumes. This may take a while…
No volume groups found
Volume group “VolGroup00” not found
ERROR: /bin/lvm exited abnormally! (pid 460)
Mount: error 6 mounting ext3
Mount: error 2 mounting none

Umount /initrd/dev failed: 2

-----end-----


Boot to rescue with cd, mounts ok

#fdisk -l

Disk /dev/sda: 80.0 GB,

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 9729 78043770 8e Linux LVM

Any help would be appreciated.

Make sure their bios settings are the same. Also, what other hardware differences are there, such as disc controller, amount of memory, CPU type, video controller? Anyway, the system is not finding the LVM volume group that should be on the 2nd partition (according to the partition table you posted). Either the controller is mapping the drive incorrectly, or something happened to it. That's why I mention the BIOS settings. If you have the sata -> ata translation turned on in one machine, but not the other, then the drive geometries are likely misinterpreted.

Thanks for the tip.

The hardware move was from a Dell Optiplex 755 to a Dell Optiplex 745, I would post the differences, but I don't think they are too significant and I didn't get that far.

After you mentioned the BIOS settings I turned on Legacy support and it booted fine. Auto ran through Kudzu for new hardware and seems to be working fine now.

Thanks again.

Glad that sorted it out. It's the silly little stuff like that which drive us nuts!
