Description

Setup

  1. Install Fedora 17 on your machine
  2. After system installed, check if kexec-tools kernel-debuginfo and crash is installed via 
    rpm -q kexec-tools
    Or via yum 
    yum install kexec-tools
  3. Reserve crashkernel for kdump by grubby 
    grubby --args="crashkernl=128M" --update-kernel=$(grubby --default-kernel)
    Reboot system and check /proc/cmdline 
    cat /proc/cmdline | grep "crashkernel"
  4. Edit /etc/kdump.conf. This is an example:
     ext4 /dev/mapper/vg_dhcp6558-lv_root
    core_collector makedumpfile --nosuchoptions
    default halt
  5. Apply changes and start kdump via 
    service kdump restart

How to test

  1. Trigger crash via: 
    echo c > /proc/sysrq-trigger

Expected Results

  1. System halt
