Ubuntu :: Can't Mount Lvm Volume - Broken Disk?

Dec 27, 2010

I suspect that one of the disks is broken in my lvm setup. I need help verifying this. The only trouble is that everything looks okay in my eyes.

When i try to mount the logical partition. The system hangs.
"mount /dev/fileserver/media /var/media"

I have tried locating the problem without success. The same with a live cd.

Here are some of the commands i have run:

General :: Mount External USB Drive In Debian To A Mount Point Based On The Volume Name

May 5, 2011

How do I configure my Debian installation to mount external USB drives to mount points based on the volume names of the drives? For instance, if I have a thumb drive with the volume name of "SWORDFISH," how do I have Linux mount it at /media/SWORDFISH? I'm aware that this can be setup in FSTAB, but that requires that I know the UUID of the device beforehand and that I take the time to set each external device up in FSTAB first. That does nothing for me when I have a thumb drive that has never been plugged into my computer before.

This seems to be setup by default in Ubuntu/Kubuntu, but is not working for me with a fresh installation of Debian Squeeze and KDE4. I've spent the past 2 hours Googling for a solution and have turned up nothing. UPDATE: My results are inconsistent. Sometimes Debian mounts devices to mount points based on the volume names, and other times it gives them generic mount points (e.g. /media/usb1).

Software :: Mount Error: Can't Mount An Encrypted Volume With An Overlaying Ext3 FS

Jun 6, 2010

I created a encrypted volume on top of software raid1. These are my steps:

1. Create logical partition on sda

2. Create logical partition on sdb (same size)

3. Change type to partition to 'fd' for both partitions

4. Check that the both partitions are same size and type
fdisk -l /dev/sda && fdisk -l /dev/sdb

5. partprobe

6. Make sure there are no remains from previous RAID installations on /dev/sdb by running:
mdadm --zero-superblock /dev/sda6
mdadm --zero-superblock /dev/sdb6

7. mdadm --create /dev/md4 --level=1 --raid-disks=2 /dev/sda6 /dev/sdb6

8. watch cat /proc/mdstat

9. update mdadm.conf
mdadm --examine --scan | grep mdx >> /etc/mdadm.conf

10. Load twofish module
[root@localhost ~]# modprobe twofish

11. # cryptsetup -y -c twofish-cbc-essiv:sha256 create ftdata /dev/md4
Enter passphrase:
Verify passphrase:

12. mkfs.ext3 -b 4096 -R stride=8 /dev/mapper/ftdata

13. mkdir /ftdata

14. Mount the encrypted volume: mount -O noatime /dev/mapper/ftdata /ftdata

It mounts successfully this first time. When I cd /ftdata, I can see the lost+found dir

Now, I unmount the volume
cd ~

Code:
umount /ftdata
cryptsetup remove ftdata

And now, if I try to setup my encrypted volume like this:

Code:
[root@localhost ~]# cryptsetup create ftdata /dev/md4
Enter passphrase:
mount -O noatime /dev/mapper/ftdata /ftdata
I get this error:
mount: you must specify the filesystem type

[Code].....

Software :: Recover Data From DVD With Broken Volume Descriptor?

Oct 14, 2010

I have a multisession DVD-R with an unreadable volume descriptor caused by a bad DVD burning using growisofs. The DVD is not physically damaged. I tried to recover the data reading directly from /dev/hdc but it throws an input/output error. I believe the error is caused by the broken volume descriptor. That's why I'd like to know a way to make a low-level DVD image that doesn't use the volume descriptor.
Once I have the image I'll manage to recover the data, but now i can't access anything at all. By the way, i've already tried all this programs and anyone worked:

CD-DVD Data Recovery
JuiceSoft Bad CD DVD Recovery
burnaware

CentOS 5 :: Gnome-volume-control Broken After Yum Update?

May 19, 2010

My challenge today is a broken sound mixer in gnome. Yesterday I run 'yum update' and it installed about 200 updates. This morning I rebooted, when double-clicking the 'speaker' icon in the top right corner of my gnome and I got a "crash".

(I have to go to mixer and enable 'front speakers' before I get any sound - thats something else i'd like to fix one day) Here is what bug-buddy has to say:

Distribution: CentOS release 5.5 (Final)
Gnome Release: 2.16.0 2007-02-18 (CentOS)
BugBuddy Version: 2.16.0
Memory status: size: 265785344 vsize: 265785344 resident: 10158080 share: 7

[Code]...

Any advice would be great - i think I should start by reinstalling the gnome mixer, but not sure which 'yum' that is contained in. I did do some reading about rolling back, but I read that is by default disabled!! Arh! why! only when you broke something you realise you need to turn it on.... o well hey ho.

Ubuntu :: Unable To Mount The Volume C - OS

Jan 19, 2009

My Windows-system has broken down and I can't reach my files on the hard drive, because i'm unable to boot Windows.

I am running Linux from the cd, but when I try to open the hard drive, it gives me an error: 'Unable to mount the volume 'C:OS''

Details: '$LogFile indicates unclean shutdown (0,0). Failed to mount '/dev/sda1': Operation not supported Mount is denied because NTFS is marked to be in use.

Choose one action:

Choice 1: If you have Windows then disconnect the external devices by clicking on the 'Safely Remove Hardware' icon in the Windows taskbar then shutdown Windows cleanly.

Choice 2: If you don't have Windows then you can use the 'force' option for your own responsibility.

For example type on the command line: mount -t ntfs-3g /dev/sda1 /media/OS -oforce Or add the option to the relevant row in the /etc/fstab file: /dev/sda1/media/OS ntfs-3g defaults,force 0 0

Ubuntu :: Data Recovery On My Broken Disk

Mar 22, 2010

A 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.

Ubuntu Installation :: Nfs Mount Broken Since Upgrading To 11.04

Apr 5, 2011

I've just upgraded to the 11.04 beta, everything working fine to start with (apart from not being able to find anything in the new interface!), but now, a few days later, the nfs mounts to my NAS are broken. I've had a quick go at manually mounting; for instance, if I try to mount 192.168.1.1/Public to /home/Public (where it usually is) it says that the mount point doesn't exist. It's not true, I can see it, and if I test it by trying a mkdir it confirms it. This is a pretty big deal, I've got ALL my stuff on the NAS. I can still see it from my phone and the web interface of the NAS, so I know it's there...Should I just re-install 10.10 and be patient until the final release comes out?

Ubuntu :: Error - Unable To Mount The Volume

Jun 2, 2010

I didn't have Linux until the day Windows crashed on me for the gazillionth time. I was simply playing some music in Windows Media Player as the entire PC froze. No CTRL+ALT+DEL, no alt F4... so I was forced to hard-reset my computer using the ON-button. After that it never launched Windows again simply because it didn't feel like it. Now, we're not here to find out why Windows is a bitch about all this, my real problem lays somewhere else. Seeing as a lot of important files were on my Windows drive I figured I could just install Linux on the other drive and fetch the files from there. The problem is I can't. Every time I attempt to open the disk I get the following error:

Quote:

Cannot mount volume.
Unable to mount the volume.

Hibernated non-system partition, refused to mount. Failed to mount '/dev/sda2': Operation not permitted. The NTFS partition is hibernated. resume and shutdown Windows properly, or mount the volume 'read-only' with the ro-option. Or mount the volume 'read-write' with the remove_hiberfile-option.

Code:

mount -t ntfs-3g /dev/sda2 /media/disk -o remove_hiberfile

I've tried both the ro-option and the remove_hiberfile but in both cases I'm given this error in the console:

Quote:

Mount is denied because NTFS is marked to be in use.

Choice 1: If you have Windows.. click on the 'Safely Remove Hardware' icon in Windows task bar to shutdown Windows cleanly..

Choice 2: If you do not have Windows then you can use the 'force' option...

And thus looping me back to the first command, upon entering I will again receive the first error. Things I have tried:

- said commands or slight variants

- re-installing windows (gets stuck during installation)

- used the Ultimate Boot CD in an attempt to access and copy the files from my Windows Drive onto an external hard drive / my Linux drive

- clicking the Drive icon furiously for a period of time in hope of a different result (which obviously did not work) Seeing as I can't screw open my laptop and take the drive out I'm really hoping there is some way for me to connect to the drive from Linux and extract the files.

- most likely my Windows system files have gone corrupt and I will need a format, but I'm not willing to do that unless I'm a 100% sure there is no way for me to extract the files first. I have an Acer ASPIRE 7720G (laptop) running an Intel Core Duo T7500 and have 2 physical hard drives (each as one large partition) of 500GB, further more it has 4GB DDR2 RAM memory and a fancy graphics card.

Ubuntu :: Couldn't Mount The New Volume After A Reboot

Oct 5, 2010

It's been days that I've been with this and I'm getting to the end of my wits.

I tried to create a RAID-5 volume with three identical 1tb drives. I did so, but I couldn't mount the new volume after a reboot. Mdadm --detail told me that of the three drives, two were in use with one as a hot spare. This isn't what I wanted.

So I deleted the volume with the following commands:

mdadm --stop /dev/md0
mdadm --zero-superblock /dev/sdb /dev/sdc /dev/sdd
mdadm --remove /dev/md0

Then I rebooted the machine, and used fdisk to delete the linux raid partitions and re-write an empty partition table on each of the drives. I rebooted again.

Now I'm trying to start over. I purged mdadm, removed the /etc/mdadm/mdadm.conf file, and now I'm back at square one.

Now for whatever reason I can't change the partition tables on the drives (/dev/sdb /dev/sdc /dev/sdd). When I try to make a new ext3 filesystem on one of the drives, I get this error:

"/dev/sdb1 is apparently in use by the sytem; will not make a filesystem here!"

I think that the system still thinks that mdadm still has some weird control of my drives and won't release them. Never mind that all I want to do even now is just make a RAID-5 volume. I've never had such difficulty before.

Ubuntu :: Lvm Volume Shown In Test Disk But Not The Partitions

Jan 29, 2011

I have 2 hdd

lvm was created in 2nd partition type primary.

yesterday i had deleted all partitions in the first drive of windows only from ubuntu disk utility. today i went to install windows and the partition space was shown as [139gb] , i thought this is the first hard disk. But my guess is windows must have taken the free space on my home partition inside lvm[ 150gb which roughly translates to 139 GiB.

SO first i deleted the whole partition of 139gb which was shown different in unallocated space as a slight less figure and then i created a 30gb partition on that space shown and went ahead, windows post creation again showed 139gb and then gave a message on next window that partition does not contain data to install windows xp. Strange i thought, this becoz next screen before the format partition as ntfs is all to be shown. Then i just felt something fishy and rebooted and then ubuntu of 2nd hdd is not booting.

I ran test disk from gparted live cd and i find td recovered the boot drive but not the 2nd primary partition in which lvm [root,home,swap] is created. It shows the lvm as 279gb. But not the 3 logical partitions inside it.

Now when i boot post the grub menu i get the following message

This disk contains all my data and the first drive was also wiped out full. test disk is not able to get anything on that windows drive.........

Ubuntu Security :: Auto Mount The Truecrypt Volume?

Feb 9, 2010

I have a 2nd hard drive that I have encrypted using true crypt. Is it possible to set this up with key files (or some other way) to auto mount when linux boots. I need it in true crypt because there are some work programs I dual boot to use in windows, and need to have access to the drive in XP from time to time, and true crypt can mount there as well. But 90+% of my time is in linux and I would like to have it auto mount through fstab (or whatever way it needs to be). My entire linux setup has been set up with encryption through dm crypt and LUKS (except for /boot). So I would think having a key file stored on the computer and an auto mount fstab would be just as secure as however secure my LUKS setup is. So any way to auto mount a true crypt 2nd drive volume?

Ubuntu :: Unable To Mount Volume - Drive Not Found

Feb 18, 2010

I am not well versed in using Ubuntu. I was using Win XP Pro SP3 on my old machine. I decided to make the move to Ubuntu. No problem since all files on the primary drive of the old machine were just OS related. I kept all of the important stuff (music, documents, reg codes, etc.) The computer had no problem importing the songs on the external drive to the music library. I am playing songs and loving it. Now the problem... when I am starting with ubuntu I don't find the drive and I can't mount it.

I get a box stating:
You are not privileged to mount this volume
DBus error org.freedesktop.DBus.Error.NoReply:
