Linux Server Problems
 

Guys I am not sure whether this is the right place for this question. If it is not please ignore.

I am currently working as Linux Administrator. I am trying for job and I am frequently getting some questions which I was not able to answer. I did't get my expected answer in google.

Q: How do you upgrade your Linux kernel explain it in step by step.

Q: If you see "Kernel Panic" error of your Linux machine and it is not booting up, What do you do. Explain the troubleshooting steps

Q: Consider that you are having an LVM with two harddisk /dev/sda1 and /dev/sda2 with Volume Group name VG01 and Logical Volume name LV01. It is up and running fine in production environment. If I want to remove /dev/sda2 Physical Volume what are the steps you will follow.

Please give me solution for my problem. Thanks in Advance.

Upgrading the kernel is a task listed in the documentation of the Linux distribution you use. See for example https://access.redhat.com/documentat...ch-kernel.html or https://access.redhat.com/documentat...he_Kernel.html.


Troubleshooting kernel panics isn't trivial but it's not like it hasn't been documented either. See for example https://access.redhat.com/node/450883/423/1.


I won't as I avoid using LVM as much as I can :-]

Hi unSpawn,

Thank You!!!

"It is strongly recommended that you keep the old kernel in case there are problems with the new kernel.
DO NOT USE -U OPTION TO UPGRADE YOUR LINUX KERNEL ALWAYS USE -i TO INSTALL IT".
