What were you trying to do that didn't work?

I tried to specify a dump target that is not in /etc/fstab. But kdump.service failed with "Dump target is invalid". Note "kdumpctl rebuild" still works.

What is the impact of this issue to you?

kdump will fail for target not listed in /etc/fstab.

Please provide the package NVR for which the bug is seen:

kdump-utils-1.0.54-7.el10.x86_64

How reproducible is this bug?:

always

Steps to reproduce

1. Create a system with additional partition (e.g. beaker job or using testing-farm "testing-farm reserve --compose RHEL-10.1-Nightly --arch x86_64 --kickstart @ks2.yaml --pool beaker", ks2.yaml has the following content,

   pre-install: |
       %pre --log=/dev/console
       disk=$(lsblk | grep disk | awk '{print $1}')
       echo $disk
       %end
   script: |
       lang en_US.UTF-8
       zerombr
       clearpart --all --initlabel
       part biosboot --fstype=biosboot --size=1
       part /boot --fstype="xfs" --size=200
       part /thinp --fstype="xfs" --size=200
       part swap --fstype="swap" --size=4096
       part / --fstype="xfs" --size=10000 --grow
   metadata: "no_autopart"

1. umount && remove the additional partition from /etc/fstab and specify it as dump target in /etc/kdump.conf

   xfs UUID=998178f8-a119-4a8d-b7b1-bebd9848e14c
   

1.  kdumpctl restart

Expected results

kdumpctl restart should succeed.

Actual results

# kdumpctl restart
kdump: kexec: unloaded kdump kernel
kdump: Stopping kdump: [OK]
kdump: Detected change(s) in the following file(s):  /etc/kdump.conf /etc/fstab
kdump: Dump target is invalid
kdump: Starting kdump: [FAILED]
