Ubuntu :: Retrieving Files From Root.disk?
Jun 24, 2010
So I had a problem with my ubuntu 10.04 on wubi. so i saved the root.disk and uninstalled it then reinstalled unbuntu 10.04 as another partition. I did the mount thing with the root.disk and now and trying to move files over. I need permission for that and its asking me for a sudo password and i didnt set one. i tried using sudo bash and its also not working.
Code:
igor@igor-laptop:~$ sudo bash
root@igor-laptop:~# mv '/mnt/usr/share/themes' '/usr/share'
mv: inter-device move failed: `/mnt/usr/share/themes' to `/usr/share/themes'; unable to remove target: Is a directory

I've been running various releases of Suse Linux on my home PC for about 6 years (currently running Suse 11.2). The old hard disk in that machine is starting to experience read errors, so I bought a new disk to put into the PC which otherwise works fine.
So I figure now is a good time to give Ubuntu a try. I plan to install the KDE version of ubuntu on the new drive, but once that's finished I will want to mount the old disk and copy as much as I can off of it onto the new disk (JPEGs, old documents, stuff under my home directory.
The old disk uses Reiser. I have read various threads concerning problems with mounting Reiser FS disks under ubuntu, but many of them are old so it's not clear to me what the current status of support for Reiser in ubuntu is.
I am planning to do the following:
1) Remove the old disk from the PC, put the new disk in its place.
2) Install kubuntu on the new disk.
3) Put the old disk back into the machine along with the new one with the old one being the slave/secondary disk so that when I power up the machine, it will be running ubuntu off of the new disk.
At this point I will want to mount the old disk so I can then start copying files off of it.
What do I need to do to mount the old disk, keeping in mind it uses the Reiser file system?

I'm running CentOS 5.5.
A couple of weeks ago, my 500 GB disk crashed after suffering an accelerating error rate for a couple of days.
Now that I have a new disk in place, I want to mount my old disk, which is (was) an LVM disk, as a second disk and recover files from it if possible.
The question is, how do I go about this?
If I mount the old disk:
# mount /dev/sdb1 /sdb1
the top-level directory shows only two subdirectories:
lost+found, which is empty; restored, which is an image of files recovered from old disk's predecessor.
'df' shows (or appears to show) that the disk is 11% full. Sorry, I don't recall how full the disk was before it crashed.
How do I get the system to recognize the LVM structure on the old disk & mount it?
Or is the directory structure too corrupted? Do I need to send the disk out to a recovery service?
P.S. Have aleady done some poking around with lvmdiskscan, which shows the old disk whether it's mounted or not, and vgchange -ay, which doesn't appear to do anything.

I've been having a problem with this "BusyBox", and unlike windows, my files are not able to be "stolen" to another operating system. I need to get my files back from /home back.

I'm running out of space in wubi. Online wubi help didn't help much since they suggest creating extra virtual disk space(similar to having a diffrent partition i guess) .None of them speak about increasing the size of /root disk space(or root.disk). I store all files in space shared with windows or external disk and use ubuntu only to install and use softwares and browsing. So how do increase the available space for installing more softwares?

A co-worker was asking me if there was a way to recuperate his child's baptism photos from his HD after it had been reformatted following a crash. I heard that this was possible and even downloaded a few trial programs, but have yet to try them.

I can't mount my Ubuntu partition. I was using my PC when it suddenly crashed, so I rebooted. When Ubuntu started again, it said that it was mounting, but I rebooted again. So, now when I start it tries to mount the main partition but it can't. Then appears <initramfs> and I don't know what to do.

I was using Ubuntu, installed over Wubi in WindowsXP. Due to some hard disk issues, I was having some problems booting into Windows. But Ubuntu was working fine. So i backed up all my data from Ubuntu and somehow managed to back up the 'root.disk' from Windows.That hard disk turned out to have some bad sectors. Now I am over a new hard disk with all my data and WindowsXP freshly installed. I want to have my old copy of Ubuntu back as I have the 'root.disk' file with me. How shall I proceed?I tried installing a fresh copy of Ubuntu using Wubi and then replace the 'root.disk' file. But it showed some Grub error.

When i installed ubuntu. I made a seperate partition so that i could copy an ISO image onto it of an up-to-date version of ubuntu. I wanted to then boot the ISO up so i could install the version that way.I've already tried doing it through the update manager but it'll download, almost be done with installing and it freezes on me. so i figured this would be easier. However i do not know how to gain access to the other partition to copy the ISO image.

My root partition seems to be full bur is wrong because I have a partition with 15Gb space and the data is arround 7.5Gb I have:
Quote:
~$
PHP Code:
sudo df -lha
S.ficheros Tama�o Usado Disp Uso% Montado en
/dev/sda5 15G 14G 660M 96% /
proc 0 0 0 - /proc
/sys 0 0 0 - /sys
[code]....
When I look for specific info about what is taking the space using du command I get that the space used by the root system is 7.2Gb. I get to the same conclusion when checking the space with Nautilus.

I've downloaded Ubuntu 8.10 and I have installed it within ms windows. My first problem was when I went to boot Ubuntu and the graphics weren't right so I rebooted it with a different graphic configuration and it installed successfully. When I went to boot Ubuntu a second time to actually use it I got the following error:
ALERT! /host/ubuntu/disks/root.disk does not exist. Dropping to a shell!
BusyBox v1.10.2 (Ubuntu 1:1.10.2-1ubuntu6) built-in shell (ash)

Running RHEL 5 in a VMWare image, needed to add a second virtual disk, which worked fine - added it in VMWare, used fdisk and mkfs to format and mounted it as /SI50 so I could then access it. Did all this as root of course. Now I have created a new user and when I log in not only do I not see the new drive, but if I try and mount the drive I get an error "only root can do that". I absolutely have to see this drive as this new user so mounting it only for root to see is no good at all. I'm sure I'm fundamentally doing something wrong here, because obviously the way drives appear in Linux is completely different to windows.

With the continued growth of SATA devices, I have really been having problems with my boot loader. In the old days, it was pretty easy to make sure that the IDE devices stayed put. However, now everything is an sd device. Specifying a root directory of /dev/sda1 in lilo is no longer a sure thing. If you have a USB device plugged in or an ESATA device, your sd devices are no longer guaranteed to stay put.In reading through the lilo documentation, it appears that you can specify root devices by UUID or even by LABEL.

I've got a new server built, shaken down and patched (2.6.18-194.el5). Works nicely.
I don't want to rebuild it from scratch if the root drive goes belly up, but I do NOT have a hardware raid controller.
The root disk should be pretty static at this point... any suggestions how I might back it up?
I was thinking I could put in another disk (same size or bigger) and use cron to run something like this nightly: dd if=/dev/sda1 of=/dev/sda2

im trying to register my openpgp key in launchpad
Quote:
Importing an OpenPGP key
To import your OpenPGP key into Launchpad, you first need the key's fingerprint.
Note: You must ensure your key is in the Ubuntu keyserver before you try to add it to Launchpad.
Retrieving the key in Ubuntu
The easiest way to generate a new OpenPGP key in Ubuntu is to use the Passwords and Encryption Keys tool. If you are using Ubuntu 10.04 or an earlier version, it is located at Applications > Accessories > Passwords and Encryption Keys. In Ubuntu 10.10 and later versions, it is located at System > Preferences > Passwords and Encryption Keys.
Step 1 Open Passwords and Encryption Keys.
Step 2 Select the My Personal Keys tab, select your key and open the property window by pressing Space Bar or double clicking with your pointer. Select the Details tab of the property window.
Step 3 Select the Fingerprint text (the ten blocks of numbers and letter). Copy the text by pressing the Ctrl+c keys together.
Retrieving the key using the GPG command
Open a terminal and enter:
gpg --fingerprint
GPG will display a message similar to:
pub 1024D/12345678 2007-01-26
Key fingerprint = 0464 39CD 2486 190A 2C5A 0739 0E68 04DC 16E7 CB72
Geoffrey Hayes (My OpenPGP key) <geoffrey@bungle.com>
sub 2048g/ABCDEF12 2007-01-26
Highlight and copy only the numeric fingerprint: 0464 39CD 2486 190A 2C5A 0739 0E68 04DC 16E7 CB72 in the example above.
so i followed these instructions, and there was nothing in my "personal keys", same for the command. so my question is how do i get the fingerprint to be able to register my key in launchpad?

I've got a laptop here where the Windows product key has been torn from the bottom. Windows will not boot up on this laptop (it blue screens). When I remove the hard drive from the laptop and install it into my working Windows computer, the partition shows up as "raw". However, the partition mounts under Ubuntu just fine, so I'm wondering if there are any Linux tools that will allow me to retrieve the Windows 7 product key, from within Linux...

Since the partition of windows7 (C: ) where wubi was installed was too small, I decided to reinstall wubi into another larger partition (E: ), keeping the old root.disk. Sadly when I replaced the root.disk ubuntu cannot boot, the loader says that there is no root.disk file, although it's there... I guess there is some kind of checksum about the virtual disk toward the loader is poiting... So how can I have my old ubuntu installation back?? I still have the old root.disk.

I'm wanting to run 10.10 server from a root disk located on an iSCSI server. My server is FreeBSD 8 running isc-dhcpd and is sharing out a 20GB iSCSI disk. I've run the server install CD (currently testing in VMWare), and it finds the iSCSI share without a problem. I'm able to install the OS just fine, but the problems start when I try to boot the installation. I'm booting off a gPXE iso until I can get PXE chain-loading figured out. My DHCP config looks as such:
Code:
host mm-iscsi
{
hardware ethernet 00:50:56:3f:3f:bf;
fixed-address 10.50.3.245;

Just tried installing Ubuntu 10.10 from a USB device on my Windows 7 machine but something goes wrong. Far into the installation the computer restarts, asks me which operating system I want to start (it had already done this once before) and I choose Ubuntu. Then I get three alternatives:
Ubuntu, Linux 2.6.35-22-generic
Ubuntu, Linux 2.6.35-22-generic (recovery mode)
Windows 7 (loader) (on /dev/sdb1)
I pick the top choice, and get the following message:
ALERT! /host/ubuntu/disks/root.disk does not exist. Dropping to a shell.
If I start recovery-mode i get the same message. There's some text above the message that reads "new low speed USB device using ohci_hcd and address"... Could there be a problem with the usb-drive? If I remove the USB drive I get the message: Gave up waiting for root device.
