Introduction
This HowTo describes a simple way to move your SMEServer system to another set of hardware by just moving the hard disk.
Sometimes this works without any intervention, but sometimes the boot fails with a "Kernel Panic". In this case you should follow these steps.
Backup First
Never do anything like this without a viable backup. If you have a Raid 1 system with 2 hard drives, then check you can boot from either of them, and then keep one safe in-case the procedure fails. If you have a USB hard Drive backup or some other form of backup, then I recommend you make sure it restores properly before you start.
What to Do
- Boot up the "old" system and run:
uname -r
this will give you the name of the current Kernel. 'It is needed below'.
- Remove the hard Drive and load it into the new system
- Boot from an SMEServer ISO CD into rescue mode, by typing "sme rescue" at the initial prompt.
- Select to enter rescue mode in Read/Write mode
- Type in the following code:
cd /boot mv initrd.YOUR KERNEL VERSION.img initrd.YOUR KERNEL VERSION.img.old initrd initrd.YOUR KERNEL VERSION.img YOUR KERNEL VERSION
- Then reboot and if it has worked, then the system will boot normally
