Red Hat :: Restart In Middle Of Core Upgrade?
Aug 27, 2010
my fedora box was in the process of doing an core upgrade from 2.6.33.6-147.2.4.fc13.i686 to 2.2.33.8-149.fc13.i686 and appeared to have stalled on the selinux part of the update 55% of the way through. Figuring the system wouldn't allows itself to be shutdown till it was ready i told it to do a restart. i'm running 2 raid 1's, 1 for the boot partition and 1 for fedora.End result it wont boot the newer core goes straight here
"
md: invalid raid superblock magic on sdb1
md: invalid raid superblock magic on sdb3
md: invalid raid superblock magic on sda1
[code]...
and the old core boots does a black screen with some text saying ???, then goes blue screen outline of fedora symbol filling in then pulses and shows the symbol and then just sits there.tell me this isn't the end of the os and there is a way to "recover" it or save it somehow.

Decided today is the day to do the network upgrade of my 11.3 to 11.4. One small problem: The repository has stopped responding, right in the middle of the install! Anyone have any ideas on how to recover, or should I just wait it out?

I'm now using Ubuntu 9.04 and I think of upgrading it to version 10.04 (when it shall be "stable").I'd like to know if I am supposed to modify /etc/apt/sources.list with the name of the new version even though I upgrade by "update-manager-core" with the command sudo do-release-upgrade

This is my first post and I figured why not start it off with a question!
First off, thanks for this site, I have a LOT of reading to do!
Secondly, my question is, what is the easiest way to upgrade my live server from Fedora core 4 to Fedora core 14 (latest stable version).
I have a box that is live with a couple of small active forums on it where the upgrade would take place.
I want to upgrade my box to stay up to date with the latest release of Fedora linux to take advantage of any enhancements or security fixes that has been implemented since version 4.
My box is colocated at a data center. Would it be best to upgrade from a CD or remotely? I have read there is quite a risk upgrading the OS remotely and some issues like broken files or dependencies could occur.

I have a question that has been partially answered in other posts and forums but I am still unclear. Please can someone help me out? I was previously using an Intel Atom 1.6GHz, 1GB RAM and the onboard Intel graphics adaptor for use as a media center PC. This was running Lubuntu and I could use Flash at full screen without any issues.
I have since decided to upgrade to an Acer Revo R3610 (Dual core Intel Atom 1.6GHz, 4GB RAM, Corsair SSD and Nvidia ION grpahics). I thought that as this machine was more powerful than my previous one, I could get away with ditching Lununtu and go for Ubuntu 10.10 (x86).
I have updated the machine and installed the latest Nvidia drivers. When I browse to a Flash based site all runs fine until I go to full screen then I get about 10FPS (sound remains fine). The video is unwatchable. I rebuilt the machine using Windows 7 Ultimate (x86) and tested again. Under Windows the video plays perfectly.
I have also tried using the 10.2 beta version of Flash under Ubuntu and this gives the same terrible results. I am at a loss as to where the issue lies. Is it with Nvidia's driver, Adobe's Flash under Linux or is it my Ubuntu build?

Just attempted to upgrade from 10.04 to 10.10, after having updated everything. Upon completion of the upgrade I was asked to restart, however, when I restarted the PC I was presented with the following:
GNU GRUB version 1.98+20100804-5ubuntu3
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.

Today I updated my system, I noticed that KDE would be upgraded to 4.3. Upon restart of my computer my wireless didn't work (and still doesn't) and I cannot use the desktop effects anymore (probably the graphics driver). Is there any way I can fix those problems, or downgrade my system so everything just works? I'm using Fedora 11 KDE (64-bits). And I've kept a list of all updates. Ok, I figured that it was a different version of the kernel, the update set the other kernel to default. I'm back to 2.6.29.6-217.2.8.fc11.x86_64 and everything works.

I have been running Ubuntu 9.10 for a while now. Today, I ran updates on my computer and also requested the upgrade to 10.04. Unfortunately, a few hours into it my computer hung. I had no choice but to reboot. When I did so the computer started a 10.04 screen and then went to a 'command line' for me to login. I am able to login, however, all i have is the 'command line'. What can i do now? Can I restart the upgrade from the 'command line'?

i am an ubuntu nooby, out of curiosity i installed ubuntu 11.04 alpha3 last night. Yes, i will definitely never install an alpha version unless i wish to test it! Frankly said, i first installed 386 version on a notebook which runs just fine. So I thought why not install the 64 bit version on my pc.
Unfortunately, the system did not finish the first reboot in order to complete the installation. First it always stopped at "checking battery state". There, I read that this bug is already fixed: [URL]... I came across this thread: [URL]... So I pressed Alt +F2 in order to log in and performed sudo apt-get update followed by sudo apt-get upgrade. Everytime there was a new update I hoped, that this will fix the issue. But when I shutdown the system with sudo shutdown now -h and restart again there is no progress.The only thing that changed is that the system no stops at "Stopping userspace bootsplash", whatever that means?

I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?
Here is the output of uname -a:Linux linux 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 i686 athlon i386 GNU/LinuxAnd here is the output for one of the cores from cat /proc/cpuinfo:processor : 5
vendor_id : AuthenticAMD
cpu family : 16
model : 10
model name : AMD Phenom(tm) II X6 1100T Processor
stepping : 0

Just a quick question. Does Kubuntu Karmic support core 2 E8500 out of the box or do you need the SMP kernel?

Is there any Linux API that will let me control on what core will a thread run? If not, do I have to use assembly language?

I had a working ubuntu 8.04.x system. I ran the update manager to upgrade to 10.04.1 LTS. Everything seemed to run fine up to the point where it needed a restart. Upon restart, it spews out a stream of log messages, changes the font of the log messages already displayed, and then the screen goes blank and the system does not respond to keyboard or mouse. It appears as if the system is trying to set up the monitor and messes up.
If I ESC into grub after BIOS boot, I have the option of booting two different kernels: 2.6.32-27-generic and 2.6.24-28-generic. The original ubuntu 8.04 kernel was 2.6.24-24-generic(though I did do some updates might that be the 24-28 kernel?).
Booting the 32-27 kernel results in the behavior described above.
Booting the 24-28 kernel produces a stream of log messages that scroll past to fast to read and drops into ash. One of the last messages is: !ALERT /dev/disk/by-uuid/ xxxxxx does not exist -which is true because there is very little in the /dev directory.

I upgraded to 13.1 and found the restart, shutdown buttons do not work. I have to resort to the terminal commands init 6, or poweroff. I then tried to install flash plugin. I modified the slackbuild script as per normal. Then issued the following command which seemed to succeed. But when I try to play utube movie it says flash is not installed. Do I need to rebuild the system?
Code:
root@redeemer:/tmp# installpkg flash-player-plugin-10.0_r45-x86_64-1_SBo.tgz
Verifying package flash-player-plugin-10.0_r45-x86_64-1_SBo.tgz.

I have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.

I've a Compaq CQ61 laptop, and i noticed that one of the cores is always at 100%.
I didn't check the duration of the battery but surely it will "eat" my battery in a hurry

I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.

Assume someone bind a particular process to a particular CPU core(In multi core machine) by using sched_setaffinity() like functions. Then how we can get that process running core id and CPU core utilisation of that process on that running CPU core(Pragmatically or by a Linux command)?.

Alright, so I upgraded my old fedora 10 server to Fedora 11 with a netinstall CD, but now service httpd restart is broken. I already had to delete the old config file and reinstall apache, but now I can't restart it. I can kill it and then start it manually, but it never stops the running instance and fails to bind the port. I know it's because /var/run/httpd/htpd.pid is in the wrong place, which would be /var/run/httpd.pid, but do I have to make a symlink every time I want to restart it? I edited all the config files to point to the right place, but the system does not honor them. What do I do?

I'm setting up an ubunutu server (tomcat, mysql etc) which has been going very smoothly I must say. I plan to do manual updates over ssh using "sudo apt-get update" and "sudo apt-get upgrade" but I believe sometimes these update will need a complete machine: how can I tell if I need to reboot the server after an update _using the command line_?

I just rented a godaddy dedicated, the ubuntu variety comes loaded with 8.04...(& I need PHP 5.3)Followed the directions here: URL...I did have to change my sources.list, everything after that went as expected (not like i'd know what to expect)At one point it asked if I wanted to update my grub/menu.lst to the release version, or use my old one, I updated it.Once the upgrade completed, I checked the menu.lst again to ensure it was gonna boot 10.04 (as warned by the guide)However once I sent reboot, I couldn't SSH back in, I waited 5m, 15m, tried again, still couldn't SSH then I had the server power cycled via my godaddy control panel, and still nothing, attempts on port 22 timed out & other ports were refused.
I think I overlooked something because, from what I've read here and there this is technically possible, I also just found this guide here:URL...The first user comment (above link/guide) seems to have a tip for what I'm trying.Anyways had the server re-provisioned via my control panel & I'm about to try again, only this time. uh, check the SSH settings post upgrade/pre restart?

I have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?

I've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?
2 - How can I know which core the program used?

I've been using ubuntu for a couple of years rather successfully on my dual-boot Vista/Ubuntu. It upgraded to 8.0(4?) LTS, 10.04LTS and I kept it there until this afternoon I followed the instructions on the ubuntu site to open up a terminal and update-manager --somearg to provide me with a nice little "Upgrade" button on the update manager. I clicked said button per the instructions, let it do it's downloading and whatever else it does. The last step of the installation is a system reboot. I let it do that, and then my grub menu comes up as more-or-less this:
Code:
Ubuntu 10.04 LTS, kernel 2.6.32-32-generic
Ubuntu 10.04 LTS, kernel 2.6.32-32-generic (recovery mode)
Ubuntu 10.04 LTS, kernel 2.6.24-28-generic
Ubuntu 10.04 LTS, kernel 2.6.24-28-generic (recovery mode)
Ubuntu 10.04 LTS, kernel 2.6.22-14-generic
Ubuntu 10.04 LTS, kernel 2.6.22-14-generic (recovery mode)
Ubuntu 10.04 LTS, memtest86+
Other operating systems:
Windows Vista/Longhorn (loader)
If I select the top one, I get:
Code:
Starting up ...
with a blinking cursor under the S for a LONG time (used the power switch after ~40 mins). I tried the second 2.6.32-32 option for recovery mode. It spit a bunch of gibberish to the screen for a couple seconds and then stopped, presumably doing the same thing, just with 100% more gibberish. I tried booting into Vista, that worked fine. Just to reiterate, I've not yet seen a 10 LTS login screen or desktop, and can't get one yet (just a "Starting up ...") Just to add, I did try searching, but since the only info I had to go on was 8 LTS to 10 LTS upgrade, and "Starting up ...", well those are just hard keywords to get any meaningful info.

I am using Ubuntu 10.04 on a dual-boot system with Windows 7. Yesterday I upgraded from 2.6.32-23 to 2.6.32-24. After that, pressing the shutdown button and selecting shutdown or restart (whether on the login page or after I've logged in) will only bring me back to the login page. I can shutdown or restart if I do sudo shutdown now, but I'd prefer to use the GUI. Also, there is no sound now (not a big deal, but still not good). And I can't access my storage partition (not the windows7 partition, but a third ntfs partition with data on it). I get the error message that I am unauthorized to mount. I have the only account on this computer, so I should be authorized. This one is a HUGE problem for me, because I need to be able to access my data for work. None of these were problems before the upgrade.
Oh yeah, and quickstart is not enabled. Also, if I go to Power Management, and try to alter what to do when Power Button is pressed, my only option is Ask Me. I know these have been problems/solutions to the shutdown/restart problem in the past.
