[linux-lvm] (root is lvm) Kernel panic: No init found. Try passing init= option to kernel

["Bao, Liping" <Liping Bao ca com>]

Hi, all

I am dealing with a Disaster Recovery Software. After recoveried system layout with lvm tools and recoveried data I bootup the machine,but "kernel panic" happened.

Really appreaciate your help.

 

My system is Suse Linux Enterprise Server 9(kernel 2.6.5-7.97-default).

The / partition is installed in a lvm vg.

The /boot partion is a regular partition.

 

My trace:

Before reboot, I can activate all my logic volume with command "vgchange -ay", and all of them can be mounted successfully.

Then I installed lilo.

And during bootup, I add "initrd=trace" to trace the initrd procedure, I don't find anything abnormal(dm-mod loaded,volume activated, chroot to real root succesfully...) except the kernel panic.

In my opnion, the "kernel panic" always happened during upgrading kernel.  Which problem it should be?

How can I trace the problem?

 

Thanks in advance.
