Hardware :: Ibm Bladecenter Locked Up
May 27, 2009
Not sure if this is hardware or maybe a configuration somewhere.We recently had an IBM bladecenter blade lock up. When I accessed the server via the remote console(could ping but not ssh) I saw the attached screen shot.The first line is the only thing that makes any sense to me(kmem_cache_alloc) Does this mean I have a program that is leaking memory or maybe a setting somewhere saying Im allocating too much/not enough memory?
I was reading that kmalloc should be at 128KB, does this mean the 145 for kmem_cache should be at 128? Im not really sure what all that means or how I would change it. The server has 8GB of memory plus 12GBs of swap.
I didnt see anything of note in /var/log/messages prior to the lock up, except when rebooted the time was 4 hours off. Which may be another problem with how I have ntp set up.

As reported on Launchpad as bug 574468, installation of 64-bit Ubuntu 10.04 fails on IBM Bladecenters because the installer fails to detect the CD, due to a bug that has yet to be tracked down. I've developed a workaround that will allow Ubuntu 10.04 Server to be installed on a Bladecenter blade by mounting an Ubuntu Server ISO image as a loopback device (and then further working around issues that arise from manually mounting the ISO image), and want to document it here. You will need:
1. an Ubuntu Server 10.04 CD.
2. a USB stick formatted as ext2 with the Ubuntu Server ISO image stored on it. Other file systems may work as well, however fat32 does not seem to work, as I was unable to mount a fat32 USB stick in the installer shell.
3. a Bladecenter with a CD drive and a USB port. Both devices should be "attached" to whichever blade you're trying to install Ubuntu on.
Installation Steps
1. boot your blade to the Ubuntu Server CD. Make sure the USB stick is plugged in as well.
2. proceed with the installer as normal, setting the keyboard layout, etc.
3. when the installer gets to the point where it fails to detect the CD, go back to the main menu and select "Execute Shell."
4. in the shell, mount the USB stick with commands like these:
Code:
mkdir /mnt/sdb1
mount /dev/sdb1 /mnt/sdb1
5. copy the Ubuntu Server ISO image to the /root directory of the live file system with a command like:
Code:
cp /mnt/sdb1/ubuntu-10.04-server-amd64.iso /root/ubuntu-10.04-server-amd64.iso
6. mount the Ubuntu Server ISO image as a loopback device with mountpoint /cdrom:
Code:
mount -o loop -t iso9660 /root/ubuntu-10.04-server-amd64.iso /cdrom
7. unmount the USB stick (but leave it plugged in):
Code:
umount /dev/sdb1
Unmounting the USB stick seemed to be necessary in order to work around the "Failed to determine codename" issue detailed below in steps 9 and 10.
8. type "exit" to exit the shell and go back to the main menu. From there, select the option to detect the CD ROM.
9. continue with the installation. It will go through networking and partitioning. After partitioning, however, it will fail again, complaining that it "Failed to determine codename for release."
10. at this point, go back to the main menu and choose the option to "Load installer components from CD." Then check the option that reads "Load Installer Components from an ISO Image" and press Continue.
After the packages for detecting and loading ISOs are installed, the installer should automatically search all available disk drives (mounted and unmounted) for ISO images.
It should find the ISO image stored on your USB key and mount it.the installation will continue as normal and you will not get the error message about failing to determine the codename for the release. If this process fails, go back to the command shell and unmount your USB key--for some reason I found that if the key was mounted, the installer wasn't able to auto-detect the ISO image stored on it.
The codename issue seems to be related to the installer not liking that the ISO image was mounted manually. Letting the installer find and mount the ISO image itself apparently allows it to perform whatever magic is required to allow the installation to proceed. I figured this out mostly thanks to the tip in post #3 of bug 122402. Here's hoping the real bug gets fixed soon so that all this hassle is not necessary in order to install an LTS release on popular server hardware.

As stated in the subject line, we have an IBM BladeCenter (HS22). Some of these Blades are supposed to have Windows Server 2008, some RHEL 5.3, and some a dual boot of both. The WS2008 only installs have gone just fine. However, when I went to do one of the dual boot machines (the next highest priority), I ran into problems. I did the Windows install, then went to do the RHEL. Told the installer where everything should go, like any other time I've done this (although usually on less swanky machines). Then got an error:"Your boot partition is on a disk using GPT partitioning scheme but this
machine can not boot using GPT.
This can happen if there is not enough space on your hard drive.The error must be corrected before you try to install Redhat Enterprise server. "To be honest, this was the first time I'd heard of GPT (or EFI), as I've been out of hardware/installs/etc... for a few years, other than fiddling at home in between coding projects.
So I've done some research, and so far what I'm seeing implies that the RHEL 5.3 kernel should support GPT. But that perhaps the issue is the Anaconda installer (specifically its partitioning tool). Does this sound correct? So is there a RHEL release out there with a different installer/partitioner? Or if I use a different tool to partition first, would that work? The disks aren't large enough to *require* GPT, but that's how they are by default, and down the road it'd be nice to know how to work with that, to keep things consistent. Also, the dual boot with WS2008 is much easier with GPT, as that version of Windows seems to require it.If anyone has any thoughts/confirmations/assertions that I'm horribly wrong on the above questions, or any tips on the dual booting other than that (since I'm guessing the logistics will now change with EFI from what I'm used to on older systems), it is vastly appreciated.

I'm probably dreaming, but I have a hobby project in mind that I would like feed I have an opportunity to purchase a 3 year old fully populated (14 x 3Ghz dual Xeon nodes) IBM bladecenter relatively inexpensively.I thought it would be fun to set it up as a beowulf cluster with open source xen and test the market to see what people would pay for Private virtual machines.
My thoughts are to use 64 bit Centos 5 as a base to get the beowulf cluster up and then load xen.I haven't really looked at the market but I figure I should be able to run 50 private virtual machines charging say $50 per month. I figure I can use rsync to backup the virtual machines to a different location. I plan to connect to linux based Network Storage running 3 x sata 1TB drives, probably via iSCSI. Along with the drive capacity currently on the blades I should get 2-3Tb online capacity over a Gbit network. (Cisco 14 + 4 network switch module)
I realise I have a bit of setup work to do and before I go investing a lot of time and a little money I'd appreciate some pragmatic advice as to why this may be a stupid venture.

Now I find myself locked out of SSH! I have another SSH user and I logged in on him but he doesn't have permission to chown the file back! I also tried using su root -c but it is rejecting my root password as if it is invalid, but I know it is valid! I have 2 root accounts on the system and both return "invalid passwords" ever since I chowned the damn file..Does anyone know what I can do? I am very far from the server I must be able to do it remotely. Maybe a server reboot will help?

I recently had CentOS installed, but felt that I didn't need the whole server thing, so I picked ubuntu as my OS as I have used it in the past and quite liked it. I formated my first hard drive and installed Ubuntu 10.10. My second drive is a ext3 data drive only. After installing Ubuntu, I can see the drive on the desktop, telling me that it is mounted...i think? But when I goto the drive all the folders are protected. I tried to chown with root to see the stuff but to no avail. I can't seem to change permissions on the drive either or the files.

Was able to use a dual boot (Windows 7 and Ubuntu Maverick Desktop version) with only minor microphone couldn't be accessed issue. Had the system lockup completely, even power on and power off or Magic AltSysRq combinations does not help. This happened once before but after parking the laptop for a day, it restarted without issue.
Just prior to my shutting the laptop down, response went to a crawl, the system took much longer to shut down but did. Upon restart (and since) the machine just hangs. I do not see the machine on my network.

2.After a year on Lucid 10.04 I installed all updates and did an online upgrade to 10.10 Great!3.Enthusiasm got the better of me and I clicked the upgrade to 11.04. Big mistake.4.I get the 11.04 desktop, but it has no response to mouse clicks. I'm locked out - can't click to log in to my private files.Is all lost? The cursor moves OK and the keyboard works (They are wireless and I guess I'll put on wired ones to eliminate any problem there as I fix stuff.)5.I have never done my own installation or partition work.6.There are a few things I did not back-up, and I'll miss them. Some bookmarks in Firefox may be impossible to ever find again.I really need the Evolution e-mailI dual boot with XP and am now booting up from an old 9.04 disk that I found.I thought I was doing a minor upgrade to Natty 11.04, but the screen tells me I have 2.6.32-32-generic kernel Is there any going back?

I am using a machine I SSH into to do some processing over very large files, but I am now unable to access it through ssh.The shell I had opened is not responsive, and when I try to connect again, it hangs even before asking for the password.I suspect this to be a memory problem as a couple of processes need to load a lot of the data to process it.Is there an emergency way of going back into this machine, or killing some processes to free the memory up ? I tried ssh ... 'kill -9 pid' but it is not even able to do this.Do you reckon the processing is still happening or is the machine completely idle ? How would you advise me to go back to it ? It's for my final year project, and I'm starting to stress !

I have Debian 7 with LXDE installed on a msi-based-notebook. Immediately after i make the login (in graphics mode), the LED of "num lock key" turns on and lock,making the keyboard impossible to type properly.
I've tried to reconfigure keyboard,but it had no effect. And yes,i have tried to use the "Fn key + num lock" combination, but had no effect too.

I'm having one of those days, and managed to delete some virtualbox disk images. But the virtual machines are still up and running just fine. So the deleted disk images still exist somewhere.
Is it possible to recover these files? Since they are in use and locked by Virtualbox I guess they still are completely intact and fine on the disk, but that they will be permanently deleted once VirtualBox stops.

openSUSE 11.4, 64-bit locked, can't revokeLast night I kept the computer on since some downloads was in progress. I kept the screen locked and the monitor power off (turned off using the power button inbuilt in the monitor). Not many applications were running, it was only Opera browser as I remember.This morning, it didn't wake up when I turned on the monitor. Shouldn't it show up the login screen? I saw only a black screen with white mouse pointer init.I tried clicking, moving the mouse and tried to type the password. Anything didn't work. Finally I did CTRL+ALT+BACKSPACE twice and got back to the login screen.

A few minutes ago I accepted a suggestion from update-manager for restarting my system, such that some security updates could be effective. After restarting and login in as usual, I discovered that I could not use my adminstrative rights as a sudoer. To recover them I booted again, as root, and added my username in the "admin" group. Rebooting, all seemed well again. As an extra check I installed and ran 'chkrootkit' and nothing suspect was found.What could have hapenned? Just a glitch in the system? Can a user disappear from a group for nothing?What further checks can I make to be sure that my system is safe?I'm using Ubuntu Jaunty Jakalope amd64, with kernell 2.6.28-15-generic.

Dual boot sys with ubuntu lucid lynx 10.04 on Windows 7 host.I created a dot directory (.rams) yesterday and decided to do a chmod on it. Stupidly,(you can call me a moron) I used the asterisk as a shortcut notation and in effect chmod-ed all the dirs starting with a dot. So when I tried to login, this AM,an error mesg appeared that advised me to change the permissions but I could not get into a console or the desktop. After trying several things on Windows, I simply moved the exisitng ubuntu install into another folder, ran uninstall and re-installed. But is there any way that I can access the sys to undo my stupidity? I have a ton of docs on this install.

I have a rather frustrating issue here that's been giving me hell since about 5:00AM this morning. I just got a new laptop (a Compaq CQ42-138TU) and was hoping to dual boot between Ubuntu 10.04 and Windows 7 Ultimate (64-bit).So, I partitioned the HDD (leaving the HP/Compaq restore partition and other partitions alone) and resized the partition that held the bundled copy of Windows 7 (32-bit). I resized it into two parts, installed Windows 7 Ultimate on one, and Ubuntu on the other. That's where the problems began.Selecting "Windows 7 (loader)" in Grub presented me with the first few second of the bootscreen, then a BSOD for less than a second. After that, the machine immediately rebooted and got back to Grub. Ubuntu still booted fine, but I wanted to get access to Windows back, soI attempted to fix this by running:
Code:
bootec.exe /fixmbr
through CMD.exe on my Windows install disk. Now Grub is gone, and I'm stuck with Windows that still won't

I can't log in from a locked screen anymore, such as when returning fromeep or hibernation. I can, however, work around the problem by clicking "switch user" and logging in from the GDM greeting screen. Logging in from a terminal also works.I recently had a problem where /etc/passwd, /etc/groups and some other files were deleted. But I have restored them - otherwise I couldn't log in at all.

I have a small problem with my Acer netbook (ao521) on which I dual boot windows7/ubuntu. I am new to linux and I didn't know much about dual booting so I made some errors when pratitioning and installing ubuntu (originally I had windows 7 only) but that is another issue.
The problem is that I accidently wiped the /C partition of win7 thereby deleting windows (). I had made a backup since I knew something like this could happen and I saved it in /home so now it is in /home/backup. Here it gets interesting though..I tried recovering Windows (with the built-in Acer eRecovery) and apparently this messed up Grub so I couldn't boot ubuntu..Now, I don't have a problem installing windows from scratch and then installing ubuntu afterwards (I have learned my lesson and I think I would do it right this time), but there is one folder, which contains some valuable documents and I want to access it and save the documents on a USB drive.
So, I ran ubuntu from the live cd(usb) and I mouned the /home partition (of my previous installation) and I tried accessing the backup folder that I made earlier but it said that I do not have such permission. I did some searching arround and I found out that I should mount the partition as root and copy the contents of the folder from the terminal. So far so good, but when I wrote
Code:
sudo mount /dev/sda9
it said that no such mounting point is available in /etc/fstab.
It occured to me that I could use the data in the initial /etc/fstab (from the initial ubuntu installation) and insert what I need in the current fstab. I did that but when I write /home as mounting point it apparently confuses it with the current /home so that doesn't help.
Well my question is: how can I edit fstab so I would be able to mount the partition and use it or is there any other way to access the folder in question.

I have a hard drive that I have partitioned into two large chunks. I have Fedora 12 on one, and I would like to put another distro on the other. I do most things on my Fedora, but on the Second distro, I'll be doing more sensitive things such as banking. If I wanted to "Lock out" the Banking distro, and only boot to it if I have an SD card or Flash drive, to act as a "key" would it be simple as putting the boot sector of the banking Distro onto the removable media, or is there something else I need to do?
to summarize, I'd like my system to automatically boot to Fedora, unless I have some form of removable media (preferably an SD card but Possibly a Flash drive) plugged in; in which case, I'd like it to boot to my banking Distro. What would be the easiest, way to go about this?
