General :: CentOS - Safe To Remove The First Kernel In The Installed List To Save Having Two Kernels Being Updated Everytime?

May 8, 2011

When I run yum list installed command the output shows two kernels:

[Code].....

Would it therefore be safe to remove the first kernel in the installed list to save having two kernels being updated everytime I run yum update? Or is the PAE kernel dependant upon the original?

Ubuntu Installation :: How To Manually Remove Old Kernels

Oct 20, 2010

I did a "dirty install" of Maverick over my existing Lucid system. That went very well and I am having no problems with Maverick. However, this morning, I decided to clean off the old Lucid kernels. In the past, after installing a new kernel on the same Ubuntu release, I have done this by running "aptitude search 2.6.32-24", for example, then running "sudo aptitude purge" for the kernel and header files it found.

Now that I have changed releases, aptitude no longer finds the Lucid kernels installed on my system, even though they still reside in the file system and show up on the grub2 menu. So, how do I manually find everything necessary to delete for the old Lucid kernels?

Ubuntu :: Grub2 - How To Remove Removed Kernels From Grub.cfg?

Nov 25, 2010

I followed the Grub 2 Basics steps to remove Grub 2 kernel listings.

However I'm stuck with 3 older versions that was completely_removed from Synaptic (kernel/headers/generic), but remain in grub.cfg.

Quote:

Here is my current grub.cfg:

(How do I remove *.14 *.21 *.22 from my menu entries Ubuntu-tweak is not an option for me. I like it old-school or with the tools at hand.)

Code:

I considered changing permissions for grub.cfg, but update-grub and new kernels will revert my changes.

Ubuntu Installation :: Unable To Remove Old Kernels And Their Grub Entries

Aug 1, 2010

I have a grub menu with a ton of old kernel entries that I want to delete. I've scoured this forum, and haven't found anything that works. I've tried:

Code:"the easiest way to get rid of old kernels from grub is to uninstall the package, the post-install scripts will update grub

for example my current kernel is:

uname -a
Linux hemma 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux

then remove older kernels found in /boot like this:

sudo aptitude remove linux-image-2.6.31-15-generic" When I tried that, the output showed the package being removed, but nothing was removed from the grub menu. I tried running the kernel I supposedly removed, and it wouldn't start, which is promising, but how do I get it out of the grub menu? I've also tried using Synaptic, but that didn't work either.

Ubuntu Installation :: 10.10 - Remove Old Kernels From The Grub2 Boot Screen - Error "awk: 1: Unexpected Character 0xe2"

Nov 1, 2010

I am running a dual boot system with windows 7 and Ubuntu. Both have run smoothly on my machine (Core 2 quad core on Gigabyte board) I recently upgraded to 10.10 from 10.04 via the update manager within 10.04. Following the upgrade the initial boot failed at the login screen ( i simply got the purple colored screen with a white box in the center of it). Instead of trying to figure out what went wrong, I simply re-installed 10.10 from live CD on top of the upgraded Ubuntu that was failing at the login screen. The live CD install seemed to fix everything for the most part ( I did notice some quickly flashing text right before the login screen. I think it was an error message but it was too fast to read)

My problem now is that I am trying to remove some of my old kernels from the Grub2 boot screen and I cant. I have read many posts on how to remove the old kernels, but my system is proving to be difficult. The old kernels definitely show during boot, but whenever I go into Synaptic they are not there. I have downloaded Ubuntu Tweak, and they do not show in it either. I have read the information at [URL] I went to http://www.fixthecode.com/remove-hug...sts-in-ubuntu/ and thought this would fix my problem but I keep getting an error: "awk: 1: unexpected character 0xe2" when i try to run: "dpkg -l | grep ^ii | grep 2.6.3x-xx | awk -F{print $2} I am running kernel 2.6.35-22 The kernels i want to remove are 2.6.32-23 and 2.6.32-24.

CentOS 5 :: Any Way To Remove Xen Support?

Mar 20, 2010

I have done an initial CentOS install. I've now found out that the driver that I want to install (nVidia for GPU support) will not support the Xen feature that I installed. I'd like to avoid having to re-install completely. Is there a way to remove the Xen support that is documented somewhere?

CentOS 5 :: Can I Remove 32 Bit Packages

Apr 14, 2010

If I do a fresh 'netinst' of CentOS 5.4 x64 on a server, what is the correct way to verify that no 32-bit packages were installed or mixed in with x64? Also can someone tell me if it is safe to remove those 32-bit RPM packages?
I searched the Wiki for 'Post Install Tips' and could not find anything there or on Google.

CentOS 5 :: How To Remove LVM From Initrd

Jun 28, 2010

I liked to move away from LUKS and LVM.

I just like to have a simple hard disk with 3 partitions for boot, / and swap

What i did so far is:

1.) i unlocked the disk and copied the content from /boot and / to the new disk into sda1 and sda3 (sda2 should be swap)

2.) i changed the fstab

3.) I changed the grub.conf

Somehow my settings in fstab and grub.conf are being ignored and during boot my system still complains about the missing /dev/sda2 for LVM

I do not like to use LVM.

I expect this is caused by the initrd

I already did boot from the Live CD and did chroot into my system and tryed to make a new initrd.

I used mkinitrd without any options.

During boot i still get the LVM error message, complaining about the missing /dev/sda2

CentOS 5 :: Add/Remove Software - Not Working

Mar 26, 2009

I have installed CentOS 5.2 and tried to click on the application => add/remove software

I get some error saying Unable to retrieve software information.

Cannot retrieve repository metadata (repomd.xml) for repositoryc5-media.

What I did wat disable the repository manager and unchecked c5-media.

This is the only one I can see at the repository manager screen.

Then I restarted application => add/remove software

The screen came out.

But I am expecting a similar screen as CentOS 3 or 4 which display the package management by group of Desktop, Application, Servers, Development, System.

From here I could know what I have installed and what I have not.

Anything wrong with my CentOS 5.2 ?

Kindly see attached [url]

CentOS 5 :: Want To Remove X/Gnome Completely?

Jan 18, 2010

I'm installing CentOS from the netinstall in Virtualbox now. I was about to post a different thread because Anaconda kept crashing on me. Whenever I would try to uncheck Gnome, clicking next would always fail. I really don't want Gnome, but I need to get the VM installed, so I just accepted the default software selection. (It's not an iso problem either because I originally tried the DVD as well.)I've been using Linux for several years, but I need to use a GUI-less server. I found some instructions on how to disable X by entering runlevel 3, but that's not what I want to do. Is there a meta-package that I can remove "yum remove" and it will remove all the GUI dependencies, or perhaps something like "yum groupremove"?

Server :: Remove LUKS Password On CentOS 5?

Jul 7, 2010

The reason I want to delete the LUKS password is simply that I do not want to have to put it in for each server just to get the system to boot. I am planning to cluster the servers as well and like I said before I don't want to put the password in each time since they won't be running all the time.

CentOS 5 Networking :: Xen - How To Remove Virbr0 Bridge

Apr 10, 2009

I installed Xen package on a CentOS 5.3 x86_64. After a reboot I found the virbr0 bridge configured by default. I guess that "virbr0" is the name used conventionally by Red Hat to indicate the first bridge. In other Xen installations usually it would have named "xenbr0". I did not find in which configuration or script file it was created. How is it possible to remove that "virbr0" bridge?

CentOS 5 :: Remove Unused Loaded Drivers?

Aug 9, 2010

Running # lsmod | grep -e " 0 " | wc on one of my servers running CentOS 5.5 (64 bits) reports me 32 unused modules, I mean, modules with 0 references. Am I wrong interpreting these results? If I'm not, how can I automatically clean those unused modules (i.e not manually running modprobe -r ). Some years ago there used to be a daemon called kerneld who was in charge of that task, right? What's CentOS new equivalent?

CentOS 5 :: Remove A Volume Group / Array?

Nov 16, 2010

I'm trying to do a disk upgrade on some servers. They are using LVM with DRBD on top and each LVM volume contains a Xen image. I have already created identical volumes on another volume group, copied the data and pointed DRBD to the new source (Which seems to have worked).

What I am unsure of is how to safely remove the disks. The disks are an Areca Raid 1 array and support hotswap. Can I just pull them out of the machine or is some sort of command needed to tell LVM or the kernel to disconnect from the physical array device? Is removing the raid array from the Areca management GUI first a good idea?
