Latest RHCK wipes grub entries.

Nov 28, 2018 2:15PM

I ran "rpm -Fvh kernel-3.10.0-957.1.3.el7.x86_64.rpm" today on a system that NFS-mounts a keep-cache server that pulled this kernel with yum.

After the installation completed, the RHCK is not present in grub:

# awk -F\' '/menuentry / {print $2}' /boot/grub2/grub.cfg

Oracle Linux Server 7.6, with Unbreakable Enterprise Kernel 4.14.35-1818.4.7.el7uek.x86_64

Oracle Linux Server, with Linux 0-rescue-504d46c0e8674c659a0ca7a55b068690

I reinstalled the previous kernel, and that entry returned:

# rpm -ivh --force /patchdir/kernel-3.10.0-957.0.el7.x86_64.rpm
