## Results of testing on F15: kexec worked, but apparently it tried to boot full-fledged F15 (instead of minimal kernel which saves vmcore). This failed since 128m is too small for that. Had to power-cycle the machine.

Description

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


How to test

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.
