[Spacewalk-list] New kernel not available un GRUB2 after update of CentOS7

[FRANK Michael]

Hello all,



We are running Spacewalk 2.8.



I started an update of my CentOS7 machines with Spacewalk update function (System -> package -> upgrade) and after update I scheduled a reboot.

The client is running rhn_check (Spacewalk Client Tools) 2.6.8-1.el7 at this time.



Unfortunately, I found out that none of the machines loaded the new kernel.



I checked on OS level and the new kernel is there:



[root@ ~]# ll /boot/vm*

-rwxr-xr-x. 1 root root 5397520 Jul 24  2018 /boot/vmlinuz-0-rescue-1a6db4473c7f47c39a604d037c7b6bcc

-rwxr-xr-x. 1 root root 5397520 Jun 20  2017 /boot/vmlinuz-3.10.0-514.21.2.el7.x86_64

-rwxr-xr-x  1 root root 6643904 May 15 05:28 /boot/vmlinuz-3.10.0-957.12.2.el7.x86_64



Buth the entries in GRUB2 cfg are missing:



[root@ ~]# grubby --default-kernel

/boot/vmlinuz-3.10.0-514.21.2.el7.x86_64



[root@ ~]# /usr/bin/awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg CentOS Linux (3.10.0-514.21.2.el7.x86_64) 7 (Core) CentOS Linux (0-rescue-1a6db4473c7f47c39a604d037c7b6bcc) 7 (Core)





After I did a 'yum reinstall kernel ' all was OK and the new kernel was default.



Any one an idea why the package upgrade was not able to add the correct settings to GRUB 2 config?



Thanks for any reply.
