CentOS

Hi,

I have 2 Centos 6.6 server, both same configuration and client of same repository. While the first server got updated to 6.9 but the second server got updated few packages but still same old kernel version. I have verified there is no exclude parameter in yum.conf, also all are same between both server. Any suggestions please

What is the output from

rpm -q kernel
ls -la /etc/grub.conf /boot/grub/grub.conf

/etc/grub.conf should be a symlink to ../boot/grub/grub.conf and if it is not then you need to copy the version from /etc/grub.conf to /boot/grub/grub.conf, rm the /etc file and symlink it to ../boot/grub/grub.conf

Also worth checking what the "default=" line in grub.conf is pointing to. Your file may have lots of kernels in it but if someone has manually changed the default to point to a kernel other than the latest then it will stay with that one until it's changed back.
