Hi all,
I am Bhanu.I am working on kexec,kdump now.I am naive
to this environment and have some problems related to
kexec and kdump.
I am using 2.6.15-git12-6-default kernel in suse 10.1
linux.I had gone through the kdump.txt document about
the steps to be followed and i am getting some
problems when installing kdump,kexec.
I followed the below steps
1) Download the upstream kexec-tools userspace
package
2) Applied latest consolidated kdump patch on top of
kexec-tools-1.101
3) Downloaded and built the vanilla kernel
I downloded 2.6.16-rc6.
4) Set the appropriate configuration in both the
kernels.
I am not sure where to add the line
[EMAIL PROTECTED] when booting to first kernel.
where actually we have to add the [EMAIL PROTECTED]
in /boot/grub/menu.lst.
If we can pass this as command line argument to
/sbin/reboot, can u help me with the syntax as I am
not sure about it.
I tried with adding [EMAIL PROTECTED] in the
menu.lst file and rebooted the sytem. I executed kexec
-p <vmlinux image of second kernel>
It gave invalid "-p" option error.
I tried with kexec -l <vmlinux image of second kernel>
image it resulted with the following error.
kexec_load failed: Bad address
entry = (nil)
nr_segments = 4
segment[0].buf = (nil)
segment[0].bufsz = 158
segment[0].mem = (nil)
segment[0].memsz = 158
segment[1].buf = 0xb7c00008
segment[1].bufsz = 1b23e8
segment[1].mem = 0x1000000
segment[1].memsz = 1b23e8
segment[2].buf = 0xb7bb2008
segment[2].bufsz = 4dc24
segment[2].mem = 0x11b3000
segment[2].memsz = 4dc24
segment[3].buf = 0xb7b82008
segment[3].bufsz = 2f086
segment[3].mem = 0x1202000
segment[3].memsz = 7fd54
I am not able to find kdump file in etc/sysconfig
directory.
Awaiting your response.
