I I think grub isn't seeing my updated changes when I'm setting up kdump
on F-20.
First I installed the the packages /kexec-tools/, /crash/, and
/kernel-debuginfo/.
Next I added crashkernel=128M to /GRUB_CMDLINE_LINUX/ the in
//etc/default/grub/.
Then I rebuild the grub config with:
grub2-mkconfig -o /boot/grub2/grub.cfg and it creates the file ok.
But, after rebooting, kdump hasn't started and I get the error from
systemctl status kdump:
kdump.service - Crash recovery kernel arming
Loaded: loaded (/usr/lib/systemd/system/kdump.service; enabled)

May 26 19:15:03 tesla systemd[1]: Failed to start Crash recovery kernel
arming.
May 26 19:15:03 tesla systemd[1]: Unit kdump.service entered failed state.
Which leads me to think that my grub.conf really isn't working for some
reason.
This is on an AMD system with 16 Gigs of ram, so available memory is
definitely not a problem.
Could be something else, but in any case I'm sure I'm missing something
stupid ...
Thanks.
