Cannot Boot Server To New Kernel
Jul 8, 2009
We cannot figure out why our dedicated server will not boot to the correct kernel. I've removed all other options from grub.conf but it's still booting to the default CentOS setup.
grub.conf:
Code:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.

on a RHE 3 system I installed a new Kernel. I did update lilo.conf and grub.conf but they are still booting an old kernel: 2.4.21-27.ELsmp. Please have a look at my files below and if you have any idea why please let me know.

I'm trying to put together a new 1U rackmount server that I'm intending to colocate (my first server of my own). Here are the details:
11-152-087 CHASSIS SUPERMICRO|CSE-512L-260B R
13-182-120 SERVER_MB SUPERMICRO|MBD-PDSML-LN2+
22-144-417 HD 250G|WD 7K 8M SATA2 WD2500JS
19-115-029 CPU INTEL|C2D E6750 2.66G 65N 4M R
20-134-337 MEM 1Gx2|KST KVR667D2E5K2/2G R
The stock CPU fan is obviously too big to sit in a 1U rackmount chassis, but I've got the top off and was just trying to boot up with the OEM fan to make certain everything worked (forgot to order a low-profile fan and heatsink--they're on the way).
Well, I put everything together, and it won't boot. Upon power up, there is nothing sent to the VGA port, and after a second or two, there is a hi-low alarm sound that does not stop that seems to imply the system is overheating (the MB and chassis manuals don't mention this alarm anywhere, but the read "temperature" light on the front is red). The CPU fan runs as well as the case fan, and even if I hold a huge high-velocity home fan over it, it still won't send any signal to the VGA monitor or POST.
I've checked that the power connections are good, the fans are seated properly, the memory contact is good, etc., and all I get is this hi-low chime every time I try to boot up. I think it's either a bad MB or CPU, since I can't imagine that the CPU is overheating with the heat sink and CPU fan.
Perhaps I've screwed something up, but the next issue I have is trying to figure out what could be causing the problem so I know what to return or replace. Is it the CPU? MB? RAM? Power unit? How can I test any of these without buying another set and possibly frying those?
I figured maybe some of you might have some ideas. I've built several computers over the years, but this one has me completely stymied.

I have set up Windows Small Business Server 2003 and was testing it over the past week. Everything has been going well and yesterday it requested to install an update (not to sure what it was now) and soon after the update was installed a restart was required.
After the server shutdown and tried to restart the system will not restart.
The machine powers up and then I am faced with a blank black screen (no load bar nothing). The monitor led light flashes from green to orange then to a static green light after the Dell splash screen.
I can load up into safe mode although I do not know how to work out what is wrong. I am guessing the update has caused the issue, possibly a boot sector needs repairing. There are no new additions to control panel -> install/remove programs which i believe is where all updates can be uninstalled from.

we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet.
syslog shows that just before crashing, these entries were made:
kernel: kernel BUG at mm/rmap.c:479
kernel: invalid operand:0000 [#1]
dmesg also shows this:
...
Brought up 2 CPUs
zapping low mappings.
checking if image is initramfs... it is
Freeing initrd memory: 482k freed
NET: Registered protocol family 16
PCI: PCI BIOS revision 2.10 entry at 0xf9f20, last bus=1
PCI: Using configuration type 1
mtrr: v2.0 (20020519)
mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs.
mtrr: corrected configuration.
...
i've googled these messages and they point to ram problems.
hivelocity.net claims to have done diagnostics on the box and that there were no problems reported.
they said this is a result of a sys configuration problem made by us.
any ideas?

running centos/virtuozzo 2.6.18-028stab062.3
when i configure vmware it asks at one point for kernel header files. where would i find them to match the current kernel?
i asked at parallels forums but help there is very scarce. i checked openVZ repositories and they dont yet have headers for this version.
what are my options? i have one last windows machine left and want to run it in VMware.

Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.
Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.
In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.
In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.
Apparently when they used yum it said 34.0.2 was the latest kernel.
What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.

I got this weird issue with a server, I have even contacted some server management companies as I ran out of ideas and ran out of things to try and fix it.
Lemme explain.
The server is a core2quad q6600, with 8gb ram. 2 velociraptor 300gb on raid1.
When I set the server up I had to wait on cpanel so I first went in and compiled a grsec kernel, 2.6.24.3 to be exact. Then I installed cpanel and everything else, have done the same exact procedures with countless other servers before, nothing special.
Have had this server around 10 months. It will only run right in the 2.6.24.3-grsec kernel. When you boot another kernel it will first boot very very slow, then when the server comes up everything is very very slow. Then the load will go up to like 100 with nothing special going on in the server. It;s like its loaded down like that just with basic startup functions. You will see things like service_start processes long after startup. Cpanel takes forever to start up if it does. The server is extremely slow and unusable, you are lucky if you can edit grub.conf real quick and set the default kernel back.
It does this on every kernel...Besides the 2.6.24.3-grsec which in that case it boots right up fine and dandy. It acts like a regular server then, performs good.
So any other kernel besides the 2.6.24.3-grsec simply wont work on it. There are no logs in messages, nothing like that. I looked into things that may have been built only for the 2.6.24.3-grsec kernel but couldn't really find anything that should have made such an impact.

I have a cpanel server which goes down with a kernel panic.
In the messages files, i could find the below lines.
The kernel in the server is 2.6.9-55.0.12.ELsmp #1 SMP
h/w is 4 cpu Dual Core AMD Opteron(tm) Processor 265
Is this a kernel bug?
If yes , how can i solve it?

Is it possible to upgrade a kernel on a dedicated server? I have a dedicated at Server.lu.
I opened a ticket with them, it was open for about a month with no reply.
How can I tell if GRUB or LILO is on the server somewhere?

So it seems like httpd crashed my server? I checked the Apache error_log and noticed lines like these:
Code:
*** glibc detected *** free(): invalid pointer: 0x08872c98 ***
[Fri Mar 23 15:57:03 2007] [error] [client x.x.x.x] Premature end of script headers: /home/user/public_html/forum/index.php
[Fri Mar 23 15:57:03 2007] [error] [client x.x.x.x] File does not exist: /home/user/public_html/500.shtml
When I look at the whole error_log it seems like such errors appear frequently and for different websites and PHP applications. This isn't the only glibc error, there's also stuff like "*** glibc detected *** corrupted double-linked list: 0x088e0bb8 ***". I have recently installed eAccelerator and searched the web: I'm not the only one who has such problems with eAccelerator. Do you think these glibc errors may have caused the server to crash?
Also, lately I noticed a lot of lines like these in the /var/log/messages file:
Code:
Mar 23 15:47:45 alpha kernel: post_create: setxattr failed, rc=122 (dev=sda7 ino=4318565)
and
Code:
Mar 23 15:50:56 alpha ntpd[2958]: sendto(66.111.46.200): Operation not permitted
I've done some Google'ing on the first error and it seems like someone with the same error got it fixed by running a filesystem check... By the way /dev/sda7 is my /home directory. But in order to run a filesystem check I need to disable all services and unmount /home? That's kind of a pain in the ***... In general, how long do you think it takes to run a filesystem check? Here's information about my /home partition:
Code:
/dev/sda7 198G 71G 118G 38% /home

I have a server running Fedora 4 and WHM/cPanel. I would like to upgrade the linux kernel to the latest version, so mosey in via SSH and type "yum -y upgrade". It downloads a few things and tells me everything is hunky dory.
Now, the version it says it is currently running is: 2.6.17-1.2142_FC4 #1 Tue Jul 11 22:41:14 EDT 2006
Is that the really the newest version available? Maybe I'm confused as to how this works, but if I go to kernel.org it tells me the most recent stable version of the kernel is 2.6.24.3. Is this because I am running FC4?

I've supposedly set APF firewall to start at boot time, by doing something like:
chkconfig --levels 2345 apf on
However i have my reservations to weather it is actually starting, its set to block port 80, after boot if i try and access it, the connection will get refused straight away, however if i go and manually start APF then try and access again, it will take a while, like its ignoring the connection attempt (which is good).
How could I check if APF is actually running?

I have 2 hard drives - 1 has XP pro installed (master drive) on it and the other is blank and set to slave. On the blank one i intedn to install Red Hat linux.
How is the best way to create a dual boot with these machines if each hard drive has one O/S dedicated to it.

I ran this in the meantime.

I'm not sure exactly how to phrase the question. But, I'm researching how to PXE boot a server without having a DHCP/PXE server in each vlan.
Scenario: Datacenter with dozens of servers. 1 VLAN per server. Cisco switches and routers. Each server has a serial console available for remote management (OS and BIOS are configured for serial console). If an admin wants to re-install OS, they should be able to reboot the server and tell the BIOS to initiate a PXE boot request. A central install server is available to provide the DHCP and PXE boot images.
Has anyone tried this? I have been reading about the 'ip helper-address' for Cisco to relay DHCP requests. Interested in hearing about real-world setups. Or is there a better way to accomplish remote OS installs?

I've got Centos 4 and I'm wondering what's the best way to cleanup my /boot partition?
Tried to do a yum update tonight and it included kernel, amongst other updates that belonged there so it stopped. I've googled around for commands to run and whatnot, but no go... or I just can't find it... if I had to clean it up I have an idea already about what to do, but I want to ask for advice first to see if there's an easier way.
so, how do people here clean up that partition?

I have an old server with only IDE and SCSI connectors on the mobo.
However, I have only SATA drives and no IDE available. I consider to buy an entry level PCI SATA adapter card. What do you think ? Can I install and boot Linux directly from it?
There is no raid involved.
