I tried to set up the kdump on my CentOS 5.8 system. I tried editing the /boot/grub/grub.conf and insert the line crashkernel=auto between the kernel and initrd entry. Then proceed on editing /etc/kdump.conf, set the path and core_collector and enable the kdump. After that, I reboot my system. But the OS does not boot this time. The kernel panic, it has this error: VFS: Cannot open root device "LABEL=/".
How am I to fix it? Is it because I add the crashkernel=auto line between the kernel and initrd entry on /boot/grub/grub.conf. I just followed the placement of crashkernel line on this tutorial.
