Hello everyone.
I am looking for a way to move a CentOS 4 installed production hard disk to another system (which has another hardware). The first has an nvidia sata controller (sata_nv), but the second has a via sata (sata_via). For all the rest of the hardware it can upgrade well I know, but if the sata driver is different, then the system doesn't boot because the proper driver is not included in the initrd file (grub still boots OK).
Here is the error message: Uncompressing Linux... Ok, booting the kernel. Red Hat nash version 4.2.1.8 starting mount: error 6 mounting ext3 mount: error 2 mounting none switchroot: mount failed: 22 Kernel panic - not syncing: Attempted to kill init!
Does anyone know how I could upgrade easily this initrd file to contain the proper driver, and even from another partition? Would it be possible to keep an old config-xx file and do an rpm upgrade which would automatically recompile a proper initrd-xx file for that new system?
Thanks for any help. Daniel
You could boot from a rescue disk, chroot to /mnt/sysimage, make sure that the proper driver shows in an lsmod, and re-install the current kernel rpm. That should redo the initrd. Somewhat easier than remembering the proper initrd commands.
