The server runs# uname -r2.6.18-128.4.1.el5However, today I executed yum update kernel*due to security advisory. I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
My company support a client with an old Redhead server " Linux version 2.6.9-5.ELsmp [URL] (gcc version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)) #1 SMP Wed Jan 5 19:30:39 EST 2005" My IT department wants to move this old server to a VMware machine and I'm trying to check if this project can fly. Me my self never worked on an old Linux server there for my first question is can I upgrade the kernel with the command yum -y install kernel..... and when I'm done I'm still going to have the old kernel just in case?
vmware virtual machine, the system is centos 5.4 want to upgrade the kernel 2.6.32. make menuconfig is based on the default. make; make modules_install; make install no problem, reboot the system to choose a new kernel, new kernel can not boot, the following is vastly map, right in the / boot directory, there is no 2.6.32 of the config files, do not know how the matter , in the compilation before I put / boot directory of the original system config files to the source directory cp The following is the contents of the screenshot
Today I upgraded one of my computers with the following command
% yum upgrade
Before the upgrade the computer was running CentOS 5.3 with the versionlock plugin and kernel 2.6.18-128. The update went smoothly (no dependency problems).
If I try to reboot with the new kernel (2.6.18-194), I get the following:
Found volume group VolGroup00 using metadata type lvm2 2 logical groups in VolGroup00 now active mount: error mounting /dev/root on /sysroot as ex3t: No such device setuproot: moving /dev failed: No such file or directory
[Code].....
If I reboot with the previous kernel (2.6.18-128), everything is fine.
there is a bug on the quad core B2 opteron cpu there is a beta patch available , but only for for 2.6.24 kernel i am very happy with my centos, and i would upgrade the kernel to try this patch i am new on linux, so i need a precise tutoriral to upgrade and keep the actual configuration of the kernel
I have an Nvidia graphics card,... actually I manage several workstations that run centos and have an nvidia video card. I also have a personal computer with ubuntu and an nvidia network card.
I would like to do a regular automatic update of those Centos workstations. (With a pilot group to test and then a full roll-out). Until oktober 2009 no major difference in automatic updating ubuntu and centos (apart from the differences between apt and yum):
After a kernel upgrade, the systems can not boot into it's Xorg gui, because the nvidia driver must be rebuild (=not recompiled, because this is partially object code, the driver is not opensource).
But from ubuntu 9.10 onwards, the kernel update process checks for the presence of propietary drivers like those of nvidia and does a rebuild on the reboot, so that the system can succesfully boot into the xorg GUI (and gdm or kdm) My question is: Are ther any plans for Centos to do the same, this would relief me from some upgrade hassle for the Centos workstations that I manage. Or does anyone know about a (good) automagic workaround?
I built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..
So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?
2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?
Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).
I need to downgrade glibc due to a broken kernel after a libc6 upgrade attempt. See:[URL]..Especially with the reduced capabilities I have right now (few if any programs are working), how might I go about downgrading glibc to 2.6?
I have centos 5.3 workin on mini itx atom 330. i have some problem with the network when i use Samba. when i move big files the network goes down. i wanna to install the new kernel on my centos to try to fix the network problem with the new drivers includes on the new kernel.
The following is a subset of error messages I'm getting when trying to do "apt-get upgrade" or "apt-get dist-upgrade" on a machine running ubuntu server 9.10 amd64:
Code: Preparing to replace linux-image-2.6.31-22-server 2.6.31-22.60 (using .../linux-image-2.6.31-22-server_2.6.31-22.65_amd64.deb) ...
I use Centos 5.5 and I want to upgrade to PHP 5.2 I read a lot on Google about the upgrade version and I realized right to change the sources of the YUM to development environment
I use in production and I can not move the development environment.
I have a Centos 4.8 linuxbox running in VMWare ESXi 4 and the kernel is 2.6.9-89.0.11.ELsmp. Recently, this linuxbox is quite unstable, it has kernel panic once a week... But we didn't have any configuration changes on it. And I have attached the kernel panic console screen and lsmod for the server.[URL]...
I have builded my kernel through wiki manual, BUT, the kernel-headers rpm-package has not been builded. Now i have only two packages: kernel and kernel-devel. Is that ok? (i think, that it is not ok, because when i build the same version of kernel on x86_64 platform, after rpmbuild command i have kernel, kernel-devel and kernel-headers packages) My CentOS version is 5.2; platform i686; kernel, kernel-headers, kernel-devel packages 2.6.18-92.el5.
I want to upgrade kernel to 2.6..36 from 2.6.18 of CentOS 5.5. The make process is successful but prompt "could not find filesystem /dev/boot " after reboot.
Some articles suggest to edit file .config and set CONFIG_SYSFS_DEPRECATED_V2 to 'y' and re-make kernel. However, the problem still stand there after reboot again.
I have a perfectly functional Samba file and print server. I will be adding several Window 2008 servers to serve as terminal server hosts running in virtual machines. I would like to convert my Samba server to a PDC (Primary Domain Controller) for these terminal servers to use. And leave everyone else as a work group (the current situation). I'd like to
1) use /etc/password and /etc/samba/smbpasswd as the source of the user accounts
2) limit what users the terminal servers can see based on a particular group (/etc/group)
So far I have tried the example howto's on the samba site and wound up having to restore /etc/nsswitch.conf in rescue mode.
I'm using Cpanel on my server, before upgrade to new kernel, i could see 8 cores on my i7 server, now i only see 4 cores, is there anything that i need to do to have another time the 8 cores?
I installed the Centos 5.5 with XEN and put 03 virtual machines (Centos 5.5 too). I did this correctly, but I have a problem. In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors: [root@vm01 ~]# grub-install /dev/sda /dev/sda: Not found or not a block device. [root@vm01 ~]# grub-install /dev/sde /dev/sda1 does not have any corresponding BIOS drive. [root@vm01 ~]# grub-install /dev/xvda /dev/xvda: Not found or not a block device.
After upgrading to CentOS 5.3 my sendmail will no longer deliver messages using a program in my /etc/smrsh. It fails with the message "unknown mailer error 1". This program was working perfectly before I did the upgrade using yum. Here is the list of packages that were upgraded. Does anything jump out as being the source of the issue? I don't believe that sendmail itself was upgraded:
i am running cent 5.1 and would like to upgrade httpd v.2.2.3 to the latest 2.2.11 version provided by apache to resolve some ajp errors i am experiencing.
I searched but did not find any rpms for cent nor did i find any instructions on how to do this.
I performed a system update yesterday to CentOS version 5.4. Now I cannot get vmware to start. I get the error "VMware Server is installed, but it has not been (correctly) configured for the running kernel. To (re-)configure it, invoke the following command: /usr/bin/vmware-config.pl." I tried running vmware-config but that did not resolve the issue. I saw the bug related to 2.0.x (after the update), but that does not seem to apply to 1.0.9.
