The purpose of this testcase is to test that kernel crash dumps are successfully disabled on installed systems which do not meet certain criteria. The result of this test case will depend on the specifics of your hardware. Please perform the test using a system that does not meet the following minimum criteria:
- CPU Architecture: amd64 (x86_64), arm64 (aarch64), or s390x
- CPU Cores: >=4
- Memory (RAM + SWAP): >=6GiB
- Disk space in /var: 5 x (Memory)
Proceed in your native language if you wish. Instructions will remain in
English.
The test steps are as follows:
- Perform a standard install using the linked installation media.
No other special steps are required during the installation.
- Reboot into the newly installed system.
- Check on the status of kdump-tools using the following command:
kdump-config show
- Compare the result of the command with the guidance below.
The result of the kdump-config show command should show
something similar to:
$ kdump-config show
* /etc/default/kdump-tools: USE_KDUMP is not set or zero
DUMP_MODE: kdump
USE_KDUMP: 0
KDUMP_COREDIR: /var/crash
crashkernel addr: 0x
/var/lib/kdump/vmlinuz: symbolic link to /boot/vmlinuz-6.11.0-7-generic
kdump initrd:
/var/lib/kdump/initrd.img: symbolic link to /var/lib/kdump/initrd.img-6.11.0-7-generic
current state: Not ready to kdump
crashkernel suggested size: 215M
kexec command:
/sbin/kexec -p --command-line="BOOT_IMAGE=/boot/vmlinuz-6.11.0-7-generic root=UUID=8c19e778-298a-40ad-91cd-f6725092446a ro reset_devices systemd.unit=kdump-tools-dump.service nr_cpus=1 irqpoll usbcore.nousb" --initrd=/var/lib/kdump/initrd.img /var/lib/kdump/vmlinuz
Ensure that:
- current state shows Not ready to dump.
- USE_KDUMP is set to 0
Some special notes about testing:
- If the results are not as expected, please include the output of the
following command in your bug report:
sudo /usr/share/kdump-tools/kdump_set_default
If you finish the installation, please submit a 'passed' result.
If any action fails, or produces an unexpected result, please submit a 'failed' result and file a bug. Please be sure to include the bug number when you submit your result.
