Re: No kdump initial ramdisk found.

Add Boot Parameters

add below line under /etc/grub.conf

kernel /boot/vmlinuz-2.6.17-1.2519.4.21.el5 ro root=LABEL=/ rhgb quiet
crashkernel=128M@16M


open /etc/kdump.conf and uncomment dump location to /var/crash/

then run below:-

# chkconfig kdump on
# service kdump start


Warning: This will panic your kernel, killing all services on the machine

# echo 1 > /proc/sys/kernel/sysrq
# echo "c" > /proc/sysrq-trigger

if it does not dump core then run below

service kdump start

Hi

I am having issues configuring kdump on my linux server.

# service kdump start
No kdump initial ramdisk found. [WARNING]
Rebuilding /boot/initrd-2.6.18-128.el5kdump.img
/etc/kdump.conf: Could not create user1@server1:/var/crash, you probably
need to run "service kdump propagate"
Failed to run mkdumprd

how did I configure kdump?
====================
# grep crashkernel /boot/grub/grub.conf
kernel /vmlinuz-2.6.18-128.el5 ro root=/dev/sysvg/root.fs nohpet
nopmtimer powernow-k8.tscsync=1 crashkernel=128M@16M

# grep net /etc/kdump.conf
net user1@server1

The root user on this server is able to ssh to user1@server1 without
password; tested this to be working with the following command line:

#ssh -i /root/.ssh/id_rsa.us1 user1@server1


Any suggestions or pointers is appreciated.
Thanks.
