Question

CENTOS 7 reboot caused kernel mismatch between setting panel and droplet

Posted September 11, 2015 3k views

After rebooting our droplet the installed kernel (3.10.0-123.8.1.el7.886_64) no longer matches the kernel under Droplet/Settings/Kernel. As a matter of fact the droplet kernel isn’t even available in the dropdown list for us to select. Through grub2-set-default I tried changing the kernels on the droplet, but that also doesn’t seem to work. Any suggestions on how to make them match again?

Unfortunately, with CentOS 7 droplets, it is not possible to manage the kernel from the Droplet itself. You will need to select the latest kernel that is available in the dropdown and then install the corresponding package on the droplet.

Right now, the latest available kernel is 3.10.0-229.7.2.el7. To install it, run the following command and power off your droplet:

sudo yum install kernel-3.10.0-229.7.2.el7
sudo poweroff

Then, boot your droplet from the control panel.
