Re: [Mkdump-devel] Unable to load mini kernel

[rahul K. <rah...@ya...>]

I am able to create initrd image by  executing:  #mkinitrd initrd.img 2.6.12.1     command now.

I have copied this image to /boot/initrd-minik.img.

After panic, mini kernel image is not booting. 
===========================================
[root@rmdevlin1 ~]# cat /proc/mkexec/*
0x800025
/boot/initrd-minik.img
16
ro console=tty0 lpj=2367488 no-hlt dump_delay=70
/boot/minik-2.6.12.bin
1
============================================

Following is the output of mkd_conv (after reboot).
==========================================
[root@rmdevlin1 ~]# mkd_conv   /dev/sdc5 /var/dump/1
invalid dump magic.
invalid memseg list.
========================================
This means that core has not been taken.

I think I am missing some configuration.
Any pointers?
 
Thanks and regards,
Rahul

       Hello,    I am unable to load mini-kernel.    Folowing are the details.    I am using redhat linux AS 4.0.    I have patched kernel  2.6.12.1 with mkexec patch "mkexec-patch-2.6.12-2.1".      Then after booting through this patched kernel (mkexec),          I have compiled and loaded the mkexec module.      Then I have compiled minikernel   with block device driver (SCSI : Qlogic device driver). File system, swap, SMP support , networking is not enabled in this minimized kernel.    I am using /dec/sdc5 partition to save the dump.  =========================================  [root@rmdevlin1 ~]# ls -l /dev/sdc5  brw-rw----  1 root disk 8, 37 Dec 12  2006 /dev/sdc5  ==========================================    mkexec parametrs are :  =====================================  [root@rmdevlin1 ~]# cat /proc/mkexec/*  0x800025  /boot/initrd-minik.img  16  ro console=tty0 lpj=2367488 no-hlt dump_delay=20  /boot/minik-2.6.12.bin  1  ======================================    I
 faced one problem while creating initrd image:   =============================================  [root@rmdevlin1 ~]# mkinitrd --with=mkdump initrd.img 2.6.12.1  No module mkdump found for kernel 2.6.12.1, aborting.  ==============================================    Then I created initrd image by executing:  #mkinitrd initrd.img 2.6.12.1    Then I have copied this image to /boot as initrd-minik.img.    I am not able to boot minikernel. Is it because of initrd image?     Am I missing something in the configuration?            -----------
