What were you trying to do that didn't work?
The kdump crashkernel arming fails. It seems the default size has changed and only memory sizes with minimally 2G are considered now. However, the RHEL 9 minimal RAM requirement seems to be 1.5GB.
What is the impact of this issue to you?
I have to update all of our kickstart files.
Please provide the package NVR for which the bug is seen:
kexec-tools-2.0.29-7.el9
How reproducible is this bug?:
100%
Steps to reproduce
- Install a system with less than 2GB without setting the addon kickstart com_redhat_kdump or run
kdumpctl reset-crashkernel
as described in the KB article for RHEL 9
- Boot into the system or reboot the system
Expected results
Failed to start Crash recovery kernel arming
The kernel commandline confirms
crashkernel=2G-64G:256M,64G-:512M
Actual results
The crashkernel can't be armed. The kernel commandline confirms
crashkernel=2G-64G:256M,64G-:512M
Additional information
- It seems with kexec-tools-2.0.29-5.el9 the minimal size of 1G is still conidered, I see in my previously installed VM:
crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M
