[ 598.463416] Buffer I/O error on device sdf9, logical block 0
[code]....
I have a hard drive where one partition is used as part of a logical volume (LV) using LVM. The partition table is corrupted and prevents the partitions from showing as devices in /dev/. The corruption prevents the logical volume from coming on-line b/c LVM cannot find the part on the corrupted disk. I (am pretty sure) I know the block offsets and lengths for each partition on the disk but do not want to write to the disk in case I am wrong.
How do I go about recovering the logical volume in this scenario?
I inadvertently started creating a boot disk over an entire 300GB external hard drive. Needless to say, I had all sorts of data saved on there. I stopped it early on in the process by turning off the drive, but I now I don't know how to salvage what's left.

After attempting to mount the old faulty hard drive using and external caddy, I got the following message...

I'd like to attempt to recover what I can from my /home directory but unfortunately I use encryption (although I do actually know my pass phrase). What procedures and software can I use to try and recover data from this drive?
I am attempting to copy files from one server to an external USB drive on a second server. Both servers are running custom RedHat Linux, kernel 2.6. Both are setup as Check Point SecurePlatform (one is a log server and the other a management server). I am trying to archive files from one (HP DL380 G5) to the second (HP DL380 G6). I am not able to archive directly to the external usb drive when connected to the HP DL380 G5 (data gets corrupted and switches to read-only access). The external USB drive has no issues when connected to the HP DL380 G6 server, thus my reason for trying to copy the files across servers.
When I attempt to use scp to copy files between the server, I am prompted for the password. Once entered the debug shows the authentication is successful, but then no files are copied (see log below). I have tried searching for potential answers, but none have panned out. Unfortunately I can't yet post the actual scp debug log output as some of the text is viewed as a URL and not yet allowed for me. I have changed all the atsign symbols to '(a)' to avoid the URL inference.

When I installed Ubuntu, it created a folder called 'ubuntu' on my hard drive. Is there a way to recover my data from this folder and use it with a newer version of ubuntu. I can't access Ubuntu on my computer. It boots straight into Windows.

Isn't there any simple way to format the crap from the Ubuntu 10.04 Live CD? I believe that on windows, there wouldn't be that problem since the "format c:" crap just format the drive without asking questions. All I want to do is to format the drive so I can create partitions later. Also, I have only access to the live CD and I don't have any Diskette drive installed.. I believe we now live in a world where this crap isn't needed to fix a computer.
I started using Ubuntu's chat tool the other day, I gave it my Gmail username and password,and lo! it found my list of CONTACTS FROM INSIDE GMAIL!Facebook has done the same thing as well!

This is SCARY.But also, a small part of me wants to know how it was done (only a small part, this protocol sh*t is not particularly challenging, right?
View 14 Replies View RelatedNot sure where else to put this, but has anyone else ran the badblocks command on a 2TB drive? I've been running it as follows:
badblocks -wvs /dev/sda
This is a brand new drive and apparently the "Testing with pattern" stage went by pretty quick, however now I'm on the "Reading and comparing" stage and it's taking forever. Every so often it lists off a rather large number followed by the time elapsed.
At the same time I'm running badblocks on an older 200GB drive with bad sectors and it's already on the 2nd pass with no similar listing as the new drive. According to dmesg I'm getting these messages:

Error mounting: mount exited with exit code 12: Failed to read last sector (976764927): Invalid argument
Hints: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,
or the partition table is corrupt (partition is smaller than NTFS),
or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sda1': Invalid argument
The device '/dev/sda1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

1) When it gets to the "reading and comparing" phase, it seems to complete in <1s. I see other posts where people say this takes them as long as it took to write to the drive. I don't see any mention of this being quick, so I'm just afraid that badblocks is being denied read access or something.. Anyone familiar with this behaviour?
2) Obviously since it is on a sixth pass, badblocks thought that it found new bad blocks on the second pass (or later). When I check SMART, though, the drive has not re-allocated anything (despite having plenty of spares)... Doesn't this seem odd? Is there some reason why the disk would not step in upon a write fail? In fact, I thought a write fail should be transparent... Which makes me wonder if question 1 (above) is causing this...
I installed Fedora 12, 64 bit on my Dell Latitude D820 laptop with Core2 Duo processor(7200 speed) and 2 gigabyte Memory.
I have updated the yum. I have enabled the rpm repositories.
It is very weird that my system suddenly works very slowly and hangs. every time I login after a while the CPU usage goes up to the end with out any reason!
Before this I had installed Fedora 12, 32 bit and I had the exact same problem.
I have installed Fedora 6, 7, 8, 9, 10 and 11 on my laptop before and I had non of these problems with them.
The interesting point is that after hanging my system works constantly slow even when I restart my system! It is slow even in booting the BIOS and start up and choosing the kernel page!
The only remedy to get rid of the slow working for a while is to Shut down the system completely and turn it on again. Restarting do not make it work normally just shutting down makes it normal for a while.
Recently i installed Maverick on my studio 15 laptop
It frequently hangs.Nothing works and i have to restart manually Is there any other way to restart Why is it hanging frequently?
Also i installed ati radeon drivers using additional drver bundled with Maverick.

But while opening Ati catalyst control centre it says d driver isnot installed

I'm running dual boot with Vista and Ubuntu Lucid Lynx. for few days i was running Ubuntu only, downloaded some files and created some directories. few minutes ago, i switched to Vista to see something and i wanted to burn some of the files i downloaded using Ubuntu but couldn't find those folders.
i thought maybe its related to different file system or something so i switched back to Ubuntu and surprise! my folders are not there, instead i got a file, of unknown type with the same name as the folder had! in another folder case it's was an image (some print screen of my browser screen - Mozilla) and again with the name of what was the folder! first - what the hall had happened? second - can i recover my data somehow?
My pen drive and hard drive are corrupted. When I use them on windows, I get an message saying "the disk needs to be formatted:". I have tried every way of recovering data on windows but have been unsuccessful.

I have set up a virtual machine under VMware Player 3.1.2 in Debian. Operating system of this virtual machine is a Windows Server 2003. I would like to periodically test this Windows Server 2003 installation for viruses. Obvious solution would be to install an AV software under this Windows Server 2003 installation. However, I was wondering, is this possible to use NOD32 for Linux or clamav in order to test this Windows Server 2003 installation for viruses? Is NOD32 for Linux able to detect viruses inside the .vmdk file?

View 8 Replies View RelatedThis happens randomly after a reboot: I can move the mouse cursor and it works perfectly only on the Unity sidebar or whatever it's called. I can fire up applications, but once they're up they completely ignore any clicks or mouse movements (the main menu does not appear on the top bar if I move the cursor in the location that usually makes it appear). They only recognise a click on the close/iconize/maximize buttons.
The mouse works: as I said I can move the cursor and it recognises clicks on the sidebar and the window control buttons; plus, it's connected via a KVM switch both to the Linux box and to a Windows box (from which I'm writing this) and in Windows perfectly.The pattern used to be this: usually while running Firefox, the mouse and keyboard stop responding, and sometimes the whole desktop graphics become corrupted. I can Alt+F1 and go to a text-mode console, but nothing short of a reboot "fixes" things. After the reboot, about two times out of five everything works, three times out of five I get the situation described above.
For the last few hours or so, however, no amount of rebooting and sacrificing goats to the gods protecting sociopaths and Linux software developers have been able to restore mouse functionality. I click on my username on the login windowhere it works perfectly), enter the password and then only the Unity sidebar works: again, the mouse cursor moves, only clicks (right and left) are ignored, as are hotspots. In ubuntu classic there is no place where I can click and launch applications, btw - once I get in I'm basically blocked and can't do anything

The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.
I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).
These are the commands I used:
Quote:
p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*

I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...
So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.
It's still trying to use /dev/disk/by-uuid/412d... to boot.
What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

View 7 Replies View RelatedA while ago my harddrive kinda failed. I didnt notice untill I got "Grub error 17" one time when I was trying to boot my computer. The problem is not really that I couldnt log on to my computer, but rather that I have alot of important information on the computer I would hate to lose. At the time I used Ubuntu 8.04 and had reiserfs filesystem on the computer. I bought a new computer and decided to wait untill I could rescue the data before doing to much dmg to it. But I dont really remember if I tried something to fix it before I realised that it was the harddrive and bad sectors that made me get gruberror 17. Hopefully I didnt do anything.
Anyway. Now today I had some extra time, so I decided to dive in. I booted from a linux mint disk and used ddrescue to transfer all the rawdata over the network to an image file laying on an ext4 drive. Once there I used reiserfsck to try and repair the filesystem. After that i mounted the image file and tried to access the files. Thats where the probelms started. I could see the whole treestructure of the harddrive and everything seemed ok, but when i tried to open the files, none of the pictures, documents and so on could be opend, and when I tried to open stuff like MP3 files they played quite strange. Videofiles was really messy, kept changing resolution and was almost always just gray and green squares on the screen. I decided to use ddrescue and move the files from the image file and on to a clean disk. So when I was done I could mount the filesystem on the new disk, but with the same resault, so I did reiserfsck again, and when that didnt help I did a buildtree also. Still with the same resault. So I decided to investigate the data abit. Opening files at random trying to understand what had hapend. And I saw that some MP3 files (the easiest to open) was some kind of mixing between several difrent mp3 files. Some files wasnt even in the same folder, so it was probably just that the file pointer was pointing at the wrong data on the disk. I dont know how that works really, so I dont know how to go on.
So now to the question. How do I get the data back? Have I done something wrong, can I redo somethig? I still have the broken disk and can take data from it once again, but I want to wait to do that untill I really know what to do. I also still have the image file, and the disk with the copied data. I have a ubuntu 9.10 system at my disposal atm.
