i've got a non-typical problem here. i've got kvm-ed freebsd (its not so important here) stored on a block device - /dev/sdb8. i wanted to install fedora rawhide there but first i thought it's a good idea to do some backup. so here we go dd if=/dev/sdb8 of=freebsd.img bs=4k
theoretically, dd should do the thing without saying a word, but it doesn't. every time it stops after reaching 16GB filesize (partition is about 35GB) and completely locks the system (only reset helps).the dump worked only once, but when i tried to compress this big image 7z got stucked too and the system froze . the problem occurs when copying to the same drive or to different drive. i've got a partial kerneloops logs, but so far i haven't found the answer.
Code:

I just get upgraded from F10 to F12. I am having problem with switching between users. The system would freeze up and the mouse would move unresponsively, could not restart system with Ctrl-Alt Del. When it freeze up, it doesn't give error anyway on next start.I suspect the problem is doing with Web browser, If one user using browser and switch to other user without logoff, it will freeze up when other using login.It seem working on following contion.
1. It seems ok when all users quit using browser,and it doesn't matter how many times you switch between users.
2. delete all other users and operate as only one user
I have a Red Hat Enterprise (AS) 4.8 system and I need to know how to totally rebuild the system from dump tape. I have been making some full level 0 dumps of the system to the attached DAT72 tape drive... In the case the boot disk goes south, I need to reload from tape, onto a new disk drive. I know how to do this in Solaris. I assume you boot from CD to like a mini-root, then configure and mount the drive on temp mount points, restore the sys data, then load the "boot blocks" (like installboot on solaris).
I have used Dump Command to dump the application files. For Full backup the level 0 is working fine. For incremental backup I used the level 1 or 2 it is getting the error as
DUMP: Only level 0 dumps are allowed on a subdirectory DUMP: The ENTIRE dump is aborted.
The code I used =============================== #!/bin/bash #Full Day Backup Script #application folders backup #test is the username now=$(date +"%d-%m-%Y") [Code]...
Does the dump command back up entire file-systems or is it capable of backing up subsets of a file-system? And is tar capable of taking device names (for file systems) as input to be archived?
I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.
I'm working on a script. fter it has installed and removed packages, I need to configure a ton of settings. In GNOME, I understand that those settings are kept in "/home/user/.gconf". Can I create a virtual machine and configure the system through the GUI to my liking and then dump all of the settings, so that I can load them on another machine? Is it as simple as copying the directories?
I've got a Centos 5 machine running with a raid 1 SSD hard drive combo, as I don't know how or even if it's possible yet to wipe the free disk space clean I need to be careful to not fill all the free disk space. As I don't want to fill the free disk space too quickly and was wandering if it is possible to pipe the result of a mysqldump to a FTP client only writing it to the ram and not writing it to this disk.
I've done a bit of research on the subject and have found the two following commands: Code: mysqldump < mysqldump options> | gzip > outputfile.sql.gz Code: tar cf - / | ncftpput -c sonic.sega.co.jp /usr/local/backup.tar
I would like to combine the two to make something like this: Code: mysqldump mysqldump_options > | ncftpput ncftpput_options -c SERVER_IP backup.sql
I haven't actually tried my code as it seems too easy and I'm sure I've got something wrong! If this command is even correct will it prevent the sql file from being written to the hard drive to my local machine?
I'm running ubuntu 10.04 as a mythtv box and it works mostly fine. But occasionally the system will hang during booting and the last messages I can see are code...
So, I don't know. What is the problem? This system is supposed to run mostly unattended, I can't check all the time whether it booted alright.
I'm experiencing some weird short freezing issues in Squeeze and / or unstable. Everything works as usual, then the system will freeze for some seconds if I don't do anything, or resume faster if I move the mouse or hit a key on the keyboard. I thought it was a wifi related problem, as I have an intel iwl4965 , here is what I often see in dmesg: [ 2608.910307] iwl4965 0000:06:00.0: Queue 4 stuck for 2000 ms. [ 2608.910317] iwl4965 0000:06:00.0: On demand firmware reload [ 2608.912832] ieee80211 phy0: Hardware restart was requested
i'm running debian on a custom-built (no brand) box, which has been up and running for, maybe, 3-4 years with no issues whatsoever. all good parts... asus mbo, athlon, wd hd, etc. lately, every once in a while - like, say, every couple of days - i hear a "beep" from the box and the system freezes... lose the keyboard and mouse, and the display stays up but also freezes (for example, if a videos vid was playing, it would just freeze). have to physically reboot to get the system back. i assume this has nothing to do with the os or any app (although i'm usually browsing with chrome or ff when it happens). not being a hardware guy... can anybody clue me in as to how to figure out what's causing the problem?
Well i just installed ubuntu and its amazing but after playing around a little i installed compiz and when i restarted my laptop it just wont let me log on it keep freezing. i dono what to do how do i over write it or replace it or fix this problem?
iv looked on the wiki and tried what it says it doesn't work
My partner and I share the computer, so we are normally both logged in.
When we come to turn the computer off, one of us will log out then the other shuts down (to have a clean shutdown), but when either one of us uses 'Logout' the system just freezes, no response, nothing, have to turn the machine off via power button.
We can 'switch user' fine, and everything else appears ok but log out fails, I did try reporting a bug on this, but seems to have got taken over with people with dual screens / SLI cards, taking it over and its not the same thing.
I get the 'impression' its a graphics driver issue, I'm using the 'recommended' Nvidia driver (am at work and can't remember which version sorry).
I'm putting this in general, because I'm not sure if many of the specifics are relevant.I have an everex cloudbook which I purchased from eBay with hardy herron on it.I finally got around, today (I've had it for a year), to installing netbook remix 9.10 with a usb key I had also purchased from eBay.Now, during the upgrade (using update manager) from 9.10 to 10.04, the system appears to have frozen.(desktop frozen, no response to keyboard or mouse).Now, I'm not sure if something could still be happening inside there, and if it would be a good idea to let the machine site overnight before rebooting it. Frankly, it happened once already, and I rebooted, and update manager just took up where it left off once I logged in.
I have not determined what's causing these freezes. It's not a new machine, of course (everex, afaik, doesn't even exist now), so maybe netbook-remix is too taxing on the hardware? I installed xfce to get away from the bloated netbook-remix graphical menu garbage, which did seem to allow the system to run faster. Anyway, the real question here is, while the interface appears frozen, could the upgrade still be developing under the surface? (I hear a fan running in there. There is no hdd to spin, but flash memory, so I don't know if the fan is any indication of internal activity). Would you wait to reboot it? (update mgr indicated 4 hrs remaining to upgrade, in the installing upgrades phase, not downloading, appears it froze during "Running post-installation trigger install-info"). Or just reboot it and see what happens (get update mgr to start again?)? The system never froze on me with hardy. It was pretty quick and snappy, in fact.
Running Ubuntu 10.4 32bit (only) on my system with ati graphics card. I just ran a software update, and I believe a new kernel was installed. When I rebooted, I saw the "Ubuntu" loading screen, but then the system froze up and the screen went completely blank. Thinking it was a graphics issue, I tried to press escape to get into the grub bootloader. However, when I pressed escape at the proper time, the system just rebooted.
Thinking that grub was broken, I used a live cd to purge grub from my system and re-install it. When I rebooted, I got the same initial problem: I get the "Ubuntu" loading screen, but then the screen goes black and the system appears to be frozen. Again, if I press escape to try the grub bootloader, the system just reboots.
Nothing too major here but today I had a few programs open and was doing a bunch of things and suddenly the system froze.
I am on 10.04 LTS -
Are there checks that I can do to see if everything is ok?
I had to turn the power off and re-booted and everything is fine, or rather, seems to be 100% fine - but more out of curiosity Id like to see if there are some checks that I can do.
I think that ubuntu creates a log of activity if I am not mistaken?
I'm running Fedora 12 with GNOME on an old Toshiba Satellite A15. From time to time I get a system freeze, where everything stops working besides the touch pad (I can move the cursor, just can't click on anything). When I boot up, I see an error message that it skips past before I can read anything, although I have spotted the snippets 'pci' 'error' and what appears to be the 0x at the start of a memory address. When I try and shut down the system (going either by command line or the System->Shut Down part), I get to the part where it says "Unmounting filesystems..." and then it stops right there. When I boot it back up, I get an error that says "A crash in package kernel has been detected."
The same happens when I boot up after the hard freeze. It seems more frequent when I have a heavy load on system memory, but for the most part it seems random. I've seen it crash after 5 minutes with only Pidgin or gedit open, I've seen it run for weeks with over 100 Firefox tabs, Pidgin, 3 documents, and GIMP running, but it seems more likely in the second scenario. It also seems to have a chance of freezing again within 5 minutes of rebooting (even if I don't touch anything after login). I ran Fedora 8 and Fedora 10 on this computer just fine, with most of the same system settings (copied my /home folder for each upgrade). I have a dual-boot system (XP/Fedora), with a third partition for data and a 200MB partition for the boot loader. The partition with Fedora is encrypted, and the crashing while trying to unmount the filesystem implies to me that might be the problem, but whatever it is, it wasn't in Fedora 8 or 10 (at least as far as I could tell).
I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.
When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.
I've just installed OpenSuse 11.3 on my two Sony Vaio VPCF11Z1E machines (which have a Geforce GT 330M graphics card).Both machines appear to setup correctly and behave normally, but at seemingly random intervals (of the order of magnitude of 15-30 minutes) the whole system locks up for no readily apparent reason. I can still move the mouse pointer around the screen, but I cannot click on anything, and the whole keyboard is unresponsive (including any reasonable ctrl-alt-xxx which might normally help). The only way to get out of this seems to be to press and hold the power button to shut the whole machine off (which is not ideal!)
I am a convert to OpenSUSE having recently ditched Windows. I really like the latest version of OpenSUSE but keep experiencing this annoying system freeze every 20 minutes or so. I get absolutely no response from the keyboard, although I do have the mouse working. However the end result is ALWAYS a cold boot
I am running SUSE on a spare machine as follows:
DELL Optiplex GX270 standard machine with integrated peripheral devices etc. Chipsets are all up to date and the hard drive is performing without fault. 1.25 Gb Ram
I am running Ubuntu 9.10 and trying to use OpenOffice 3.1. If I run OpenOffice, after 10 minutes or so, the whole computer freezes. Even if I have shut down OpenOffice it still happens. Only answer is to turn computer off and on again. I read some other people's posts listing the same problem and as a result uninstalled Open Office and then installed it again. I also uninstalled Compiz. Neither of these seem to be the solution. I have just installed Lotus Symphony and there are no problems with freezing and so the issue is definately with OO and Ubuntu.
I then on further advice uninstalled the bundled Ubuntu version of OpenOffice and installed directly from the OpenOffice website. The problem still remains. Next thing I tried was to uncheck autosave feature. The above problems only happen on my desktop. I also have an ASUS EEE Netbook running Ubuntu 9.10 Netbook remix. This is fine - the problem does not seem to affect the netbook. I would really like to continue to use OO - I like it a lot. Unfortunately this freezing issue is making it unusable.
[I'm not sure if this is the right forum. This is the closest I've found]. I've installed Ubuntu 10.04 LTS (dual boot with Windows XP SP3). After Ubuntu starts, it takes about 10 seconds, and the computer halts. No screen/mouse/keyboard activity. If I start Ubuntu under Recovery Mode, with failsafeX, it doesn't happen.
In the Windows all is fine. What did I wrong? [My CPU is: Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz, if it matters...]
I've recently installed 10.04 LTS on a desktop PC so I can use it as a Zabbix monitoring machine.
I fresh installed and all seemed to be well but after a few restarts the system suddenly refused to boot anymore. The BIOS splash screen comes up and then a cursor blinks on the screen for a couple of seconds and then... nothing. The keyboard and monitor both go unresponsive and nothing happens.
I can hear the HD spin up and it isn't making any weird noises. Also, booting from the CD works and I can see and work with the HD so I'm not convinced that this is the problem.
In fact, I actually did a fresh reinstallation of 10.4 onto the machine and started from scratch. Again it ran fine for a few hours while I was setting Zabbix up. After a couple of restarts, again the freeze on boot.
I ran a HD scan and everything seems fine. I've also switched the HD over to the second IDE connection in the box just in case...
Does anyone else have this problem? Is it a bug? Any ideas on how to workaround it? (Short of going back to a previous Ubuntu version)
When I do some copying of files, or any background disk activity with file reading (transcoding a movie, uploading a big file to FTP, virus scanning) all computer becomes so slow, that I hardly can move my mouse, not to mention any productive use. I have SATA HDD, and Intel Quad CPU. I took measures to be sure it is not CPU or memory resource problem. Gentoo, Fedora, Windows don't freese that much on file reading. It is not a filesystem problem, or HDD, cuse I tried exactly this partition with other OSes.
Nice has a minor effect, but is is not enough, and I can't always start Nautilus with another nice level when I want to copy a file. What can I do to lower the priority of disk operations globally, and make apps to share disk thoughtput equally, not the one to occupie the disk until it finishes?
I seem to be having a problem on the new Kernel (2.6.35-23) with the system randomly freezing.
I have installed a number of things in recent days leading up to this problem, but when i boot with the old kernel i don't seem to have any issues. From this i am guessing its the new kernel.
The freezing seems (although i am not sure) to be worse when Rhythmbox is running. When it happens everything freezes, the playing song skips, replaying the same one second of music over and over. All the hotkeys stop and the mouse cursor stops responding.
I have seen people talking about system logs to look at system crashes but i don't know how to show those. I also doubt my ability to interpret them.
I'm having a problem with my Ubuntu 10.10 system. After installing the OS it worked fine. But after one or two restarts it totally freezes i mean NO Ctrl+Alt+Bckspc , NO Ctrl+Alt+F1 and Ctrl+Alt+Del works for me. I have the same problem with Ubuntu 10.04 , 9.10 also. ( Only Ubuntu version 9.04 Works fine for me ). But i want to make use the latest one. code...
After Ubuntu fails some time it crush the GRUB loader, so that i can't boot windows either. Any buddy tell me why this happen to me?
I've try to install Linux Mint 10 also but it freezes while installing..!!
Now I loaded the openSUSE 11.4 milestone 3. It works fine for now but i can't connect to internet , it asks for "linux-atm-lib" . i don't know how to do that .
