Hello
I received a WHM update notification this morning (28th April) and this ran and then offered to WHM update the Kernel and reboot as usual
I ran the update/reboot and the server lost contact -- SSH, Web, FTP all lost connection. After contacting the Hosting providers (Fasthosts) they manaully entered the server and established that the Kernel that was used to boot was corrupted and so then they reset the Server to load from an earlier Kernel.
The server now loads and runs ok, but:-
1) I need to ensure that the bad/corrupt kernel has been removed and/or cleanly reinstalled.
2) I had previously found an incomplete yum transaction which I cleaned up. Re running yum update + tidy up does not claim to need to do anything new now.
3) Fasthosts offered me a Server kernel updating system (El Repo) which is not supported by cPanel so I do not want to install it: https://www.howtoforge.com/tutorial/how-to-upgrade-kernel-in-centos-7-server/
4) The current install of WHM still asks me to reboot the system but the Fasthost engineer states that rebooting the server will revert to the most recent but corrupt kernel.
Kernel version currently operating ok:
3.10.0-1062.4.3.el7.x86_64
Kernel versions currently on the system:
kernel-3.10.0-1062.12.1.el7.x86_64
kernel-3.10.0-1062.9.1.el7.x86_64
kernel-3.10.0-1062.7.1.el7.x86_64
kernel-3.10.0-1127.el7.x86_64
kernel-3.10.0-1062.18.1.el7.x86_64
kernel-3.10.0-1062.4.3.el7.x86_64
yum reinstall kernel
wants to reinstall kernel-3.10.0-1127.el7.x86_64
How can I ensure that the current "current" kernel is stable and usable before running the WHM update process as outlined in (3)?
It might all be fine, but I don't want to risk loosing remote access to the server again. Would appreciate guidance on next steps. I am not signed up with KernelCare.
Cheers
