This test case tests the functionality of the ABRT vmcore feature.

How to test

Error creating thumbnail: File missing
Please note that this test probably can't be done using live cd.
  1. Ensure you have the plugin installed with the following command:
    • su -c 'dnf install abrt-addon-vmcore'
  2. Ensure you have necessary packages for producing vmcore and its processing:
    • su -c 'dnf install kexec-tools system-config-kdump'
  3. Ensure that the system log watcher service is running - systemctl status abrt-vmcore.service
    • If you have to change anything, restart abrtd: su -c 'systemctl restart abrtd.service'
  4. Add crashkernel=128M to kernel command line.
    • You can either use system-config-kdump, click "Enable" and then "Apply".
    • Or you can manually edit /etc/default/grub and then re-generate grub configuration file.
  5. Reboot.
  6. Ensure that the kdump service is running - systemctl status kdump.service. If it doesn't, no vmcore will be saved on crash.
  7. Crash the machine: sync; echo 1 >/proc/sys/kernel/sysrq; echo c >/proc/sysrq-trigger

Expected Results

  1. When rebooting after the crash, ABRT should detect the new vmcore appearing in /var/crash, create a crash report and notify you via the notification area.
