[Lustre-discuss] Kernel Panic error after lustre 2.0 installation

[Kevin Van Maren]

Yep.  All you have to do is rebuild the driver for the Lustre kernel.

First, bring the system back up with the non-Lustre kernel.



See the bottom of the readme:

    # cd /usr/src/linux/drivers/scsi/arcmsr
    (suppose /usr/src/linux is the soft-link for 
/usr/src/kernel/2.6.23.1-42.fc8-i386)
    # make -C /lib/modules/`uname -r`/build CONFIG_SCSI_ARCMSR=m 
SUBDIRS=$PWD modules
    # insmod arcmsr.ko

Except instead of "uname -r" substitute the lustre kernel's 'uname -r', 
as you want to build for the Lustre kernel.  Be sure you have the Lustre 
kernel-devel RPM installed.

Note that the "insmod" will not work (you already have it for the 
running kernel, and the one you built for the Lustre kernel will not 
work).  You will need to rebuild the initrd for the Lustre kernel (see 
the other instructions in the readme, using the Lustre kernel).
