I am using CentOS 5.5. After upgrading i have at present 4 kernels in the menu.lst.If i try to remove any kernel, 2.6.18-194.3.1.el5.i686 via Package Manager, i am told that i am removing critical software for system functionality etc. How delete older kernels?
View 4 RepliesWhen I run yum list installed command the output shows two kernels:

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?

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?
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.

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

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.
Why is cx88-dvb no longer included in the CentOS 5 kernels found in centosplus?
It is present in all 2.6.18-92.1.x versions, but not in 2.6.18-128.1.x versions.
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.
we have done a minimall install of centOS. We don't use software RAID, and after doing a "lsmod" we see a lot of modules loaded we dont need.
So I tried to remove the DMRAID because we don't need it. I'have added the dm_mirror, and dm_raid45 to both /etc/modprobe.d/blacklist:
blacklist dm_raid45
blacklist dm_message
blacklist dm_log
blacklist dm_log
blacklist dm_mod

View 2 Replies View RelatedIf 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.
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

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]
I am currently running the xen (64 bit) kernel, but want to move to the non xen kernel(64 bit) while retaining my carefully crafted system. I tried this once before by unticking the "virtualisation" and it removed the xen kernel, leaving me with nothing to boot from.

View 3 Replies View RelatedI'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"?

how to remove graphic mode on the server (include related packages)?
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.
View 3 Replies View RelatedI 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?

View 1 Replies View RelatedI'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?
