• URGENT: help recovering lost data

  - by Niels Kristian

  I have made a directory: sudo mkdir /ssd, the directory was supposed to be mounted to a raid array called md3. This was done by adding /dev/md3 /ssd auto defaults 0 0 to fstab. Then after a while where I had used the directory, I realized that I had forgotten to run sudo mount -a - and then I did, and now the data is gone. I tried to uncomment the line in fstab and run sudo mount -a but that didn't get back my data. What can I do!? CONTENT OF FSTAB: proc /proc proc defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 /dev/md/0 none swap sw 0 0 /dev/md/1 /boot ext3 defaults 0 0 /dev/md/2 / ext4 defaults 0 0 /dev/md3 /ssd auto defaults 0 0

• Xorg fails to start under Ubuntu

  - by den-javamaniac

  I'm running desktop Ubuntu 9.10 on my Dell laptop. Previously it was Ubuntu 9.04. After some period of time (lets say 3-4 months) my X fails to start automatically after some restart calls. If that takes place my network manager applet doesn't start either (after I do startx). Can any one point out what I'm missing/what's the problem? EDDITED I get a perfect server boot meaning there's no Xorg started. Command line interface is all I get starting from login and further.

• How do I justify to my management that we need a bandwidth upgrade?

  - by Sandeep

  I work in an office with a 8mbps line and about a 100 people. Our internet has slowed to crawl over the past few months, as we added headcount. However, using speedtest.net or other sites, still shows bandwidth as 8mbps. Now, how do I justify to management that we indeed need to upgrade our bandwidth ? Please note that I dont have access to our main routers or any network equipment. I can only use my system (windows+linux dual boot) to make a case for a reasonable justification. help!

• Win XP shut down window very slow to appear

  - by Heckmaier

  Hi all, I click Start-Shut Down and the Shut Down window takes 5 minutes to appear. This problem doesn't happen after a fresh boot, it only happens after I have been logged on for awhile. I am using a MacBookPro with Bootcamp. The machine actually shuts down quickly, its just really slow to bring up the shut down window. Basically I would like to know if: 1) Anyone has any ideas why this would happen 2) Who owns the "Shut Down" window (i.e. what happens on the OS after I click the Shut Down icon in the start menu) I've tried perusing the task manager to try and see if any processes look suspicious, but to no avail. thanks, H

• Delete Grub and OpenSuse but keep Windows 7.

  - by elvispt

  Hi. Here is my problem. I have OpenSuse installed alongside Windows 7. Grub is the boot loader from where I access OpenSuse and Windows 7. I want to delete Grub and also the OpenSuse partitions. My first, failed, approach was to insert the Win7 DVD, choose Repair your computer and then enter the commmand prompt. I then typed "bootrec /fixmbr" and restarted. It didn't worked. Grub was still there, so was Windows7. I then tried using "bootrec /fixboot and /rebuildbcd and neither worked. So what can I do to fix this? I remember when I was using WinXP this was much simpler. I would just type fixmbr and that was it. Any clues? Thank you.

• Debian can't see one of my hard drives

  - by nask00s

  Today I installed Linux Debian in dual boot with Windows 7. I have 3 hard drives, two for starage and one for the operating systems. The problem is with the two storage drives which are exactly same. In debian I can only see one of them. Before Debian I had Ubuntu and there wasn't any problem. Also I didn't changed anything from that drive. What should I do? I don't want to format it or delete anything.

• Linux Raid: Can mdadm --grow a raid1 while mounted?

  - by Chris

  I have 2 500gb drives in a RAID1 setup that I needed to upgrade for more space. I mdadm --fail'ed each drive in turn and I used dd to copy each drive to it's respective larger drive (2tb each), removed the smaller drives and replaced them with the larger drives, and reassembled the array and forced a resync. So now I've got a 500gb RAID1 sitting on 2TB drives, and wish to grow them. The plan is to use mdadm --manage /dev/md0 --grow to grow them, then boot a rescue cd, assemble the array under that environment, and do the resize2fs on them. Can I use mdadm --grow on a mounted and live filesystem? Also, do I need more options to make sure the grow operation stays raid1?

• ASUS N550 laptop not charging on ubuntu after updating kernel

  - by OBY Trance

  I'm using Ubuntu 13.10 on a pretty new ASUS N550jv laptop. When I was using kernel linux-image-3.11.0-11 everything was quite well (kinda..), however, when I updated the kernel using the automatic update, the kernels which were released afterwards (12+) were faulty on my machine, and caused the battery not to be charged and only stay at their current charging level (even when the machine was off!) The only fix I had was to roll-back to the '..11' version (on boot screen - advanced options), and hard-reboot (AC cord disconnected and reconnected) but now version 14 was released and "pushed away" the good old version 11. How can I fix that?? Please help me...

• Problem starting X in unbuntu 10.10

  - by xain

  Hi, I recently installed ubuntu 10.10 on my old toshiba a100 (where I've been running XP with no problems for ages). The installation went fine, I can log in with my user account, but after that the screen has only the wallpaper (and the mouse is enabled). Any hints on how to troubleshoot it ? These are the Xorg and the messages log files. Thanks When booted in safe graphics mode it worked just fine. Is there a way to set that configuration as the default so I don't have to go through those menus every time I boot ?

• Installing linux on computer with Marvell adapter

  - by Seth

  I recently reinstalled my computer and decided that I want to have a native installation of linux side by side with windows (got tired of VMWare). The thing is upon installation (debian) everything goes fine until the disc detection section - linux can't find my western digital 1TB drive (IDE mode). I don't have the installation disc with me now, but I think that when i changed the mode to AHCI everything worked, though Windows couldn't boot so this is not an option. I have a Marvell 91xx controller. Any ideas?

• Cloned Windows 7 to new HDD and want to change the drive letter to C

  - by Hoppe

  I used Clonezilla to clone my existing hard drive to a new one I bought. I then changed the BIOS to set the new drive as the first in the boot sequence. I'm pretty sure that I'm still running Windows 7 on the old drive. My old drive is marked as C. Now that I don't have a disk drive any more, how I do I swap the drive letter from J: to C:? I tried to change it in the disk management section of "Manage", but it reports: "the parameter is incorrect".

• Removing BIOS Post Messages

  - by Steve

  I am working on a project where a standard x86 desktop system will boot and run a single program until it is shut down. I would like to remove all the bios post messages so that it looks a little more "finished" and cleaner when it starts up. I was hoping that there might by a standard implementation/terms to know about so I can avoid having to dig through every manual to see if there are options, or get some advice on a standard set of tools I should be using. I was thinking about getting a board that has an image that covers up the post messages until you press a key and trying to customize it to all black, but it's not clear if this is a good direction. I started looking for OEM motherboards but my searches were filled with standard commercial stuff, or seemed to be way to big for my toy project. What is the best way to go about removing all the bios post messages and just having a blank screen or "loading" message until OS loads?

• How to get the finer resolution for asus eee pc 1000hd after installing windows7?

  - by vij

  Hi i have installed windows 7 on my 2 year old ASUS EEE PC 1000HD. The default Operating system it came with was windows xp. Now the system is working fine but there are some display problems which i am going to state now: Firstly, during booting windows 7 logo is missing. There are no options for resolution changes. The only option possible is 800x600. The boot time is quite long when compared to xp. The graphics driver used in this system is STANDARD VGA GRAPHICS ADAPTER. The processor is intel celeron with 1GB RAM. I think with these requirements it is possible to get windows 7 with finer resolution. But why these problems are occurring?I even tried to install graphics driver provided by intel for this system. But i ve got the error message "this system doesn't meet the necessary requirements". So how to overcome this problem??

• "SIOCSIFADDR: No such device" after restoring backup

  - by Paul Tomblin

  I bought some new hardware, and tried to restore my backup on it. When I boot, I don't get a network connection. If I type "ifup eth0" on the command line, I see the messages: SIOCSIFADDR: No such device eth0: No such device lspci shows an ethernet controller (Intel 82546GB). ifconfig does not show any controller except loopback. I tried installing bare Debian on the machine and the network worked then, but now I want to make it like my old machine was. Googling this problem only seems to find people having this problem in VMs. I'm not in a VM.

• Fusion 3, Windows 7, frequent blue screens

  - by kenny6127

  Is anyone else seeing this problem? A solution would be great (hey, it's Windows, it's gonna blue screen, just gotta deal with it), but it's also nice to know if it's something specific to my configuration, or if a lot of folks are having the same issue. Here's the details: * MacBook Pro 15" unibody, 4 GB, 2.4 GHz, 10.5.8 * Fusion 3.0.1 * Windows 7 Pro, 32-bit (clean install, not migrated from Boot Camp or anything) Blue screens happen nearly every time the MBP cover is closed for a short period of time (< 3 minutes). If the cover is closed for a half hour or longer, the VM is fine. I'm guessing it might be related to sleep, but that's hard to tell, and the Windows crash dump logs are pretty useless. Thanks!

• DIagnosing another Windows 7 Lockup

  - by MSEoris

  Im running windows 7 on a fairly modern machine (8gb ram, amd fx-6100, gtx 560ti) and I notice that periodically my windows seems to just hang for a little while. Frequently this occurs after a cold boot and i start up five or six small to medium sized programs, but also occasionally it occurs during normal usage. Basically what occurs is the screen locks up, there is no keyboard responsiveness for a period of 30 seconds to a full minute - after a bit of patience, control is returned, but I'm interested in figuring out what is causing such lockups. I checked the event log and dont see any issues, and all i can see in task manager is a spike in cpu and memory usage right after this occurs. Any tips on how to even begin to diagnose this? Thanks.

• KVM XML config file

  - by awmusic12635

  I have a KVM server that I expanded the LV of then rebooted. However now when booting I get the error: error: Failed to create domain from /home/kvm/kvmx/kvmx.xml error: (domain_definition):1: Document is empty (null) ^ It appears the config file still exits however it is now empty. I attempted to replace the contents of the file with the correct previous information however it continues to wipe it on attempt to boot and fails again with the same error. How would I got about solving this so the file doesn't get wiped on every reboot? OS: Centos 6 64bit I would appreciate any help you may have.

• Run command on init and restart on errors

  - by chersanya

  I have internet access on my PC through proxy through SSH, so every time I need to execute ssh -L PORT:SERVER:PORT LOGIN@SERVER and then type a password. After each network failure or reconnect this command has to be executed again. I've got bored of it and look for a way to do this automatically: first run this after boot (it doesn't seem to be a problem - put this command in some init file and that's all) and then rerun it (if possible, then type password) on each network failure. Is it possible, and how? OS Linux (Debian)

• Vista Startup - Cannot Find the File Specified

  - by Redmastif

  Yesterday I restarted my laptop because my Wi-Fi catcher wasn't working correctly, and when the computer reached the login screen, instead of showing my user account it said "Cannot find the file specified". I rebooted and ran the Startup Repair and Memory Diagnostics but nothing showed up. I also took the battery out for a minute and tried again but still no luck. The weird thing is that I cannot even boot into safe mode, it still shows the same error. I don't remember downloading or opening anything suspicious recently, and I have 3 different cleaners/anti-malware programs as well that I usually run about once a week. I did go into the registry recently but I didn't modify or delete anything as I was only checking to see if I had a certain key in it. I have a Dell laptop running Vista Home Basic SP2. If I have to I can reinstall the OS with the CD or even take it to Best Buy but I'd rather try and fix it first. Thanks.

  I mounted one vmdk file in my windows 8 machine and I am able to access all the folders and files except those in "users\ directory. When I try to open, it says I dont have permission. I am not able to give the permission even. Any one can tell me how to open the users directory? I have very important files in the desktop folder which can be acessed through \users\\desktop. What is the alternate way of accessing the folder? I lost the password to boot up the vm image.

• Debian Based Server not booting, soon after GRUB screen it restarts?

  - by Krauser

  I have tried running memtest, it start get about half way then abruptly restarts. I assume this is not a problem with the OS itself but rather a hardware issue, I have checked various logs when after about 10 reboots it starts ok, /var/log/kern.log /var/log/syslog /var/log/dmesg All I get is: EXT4-fs(sdc1): re-mounted. Opts: errors=remount-ro restart So I ran fcsk on the drive, to check if the fs was failing and it was fine. Really don't know how to find why the server is continuosly restarting andif I get lucky it will boot up.

• What are my options for a disk with what seems to be a corrupted filesystem?

  - by CT

  I have a friend with an old Dell that will not boot into Windows. It has an IDE drive. It spins up. I have an IDE to USB device. I've attached the drive via that device to a working laptop. The drive does not mount. If I go into Disk Management I can see the drive but it will not initalize, says "Drive not ready." I've also booted into a linux live cd to see if the drive mounts, it does not. I am just trying to recover some pictures from the drive. The data is not important enough to send to a professional. The issue is more of a curosity on how to recover data if and when these situations would occur in the future.
