Ubuntu :: Clone Harddisk To A New Harddisk?
Jun 18, 2011
how can I clone my installed ubuntu to a new harddisk? with 32bit ubuntu I have used:tar cvpzf -> create a tar file on my external nas system. after that I have done a restore tar xvpfz - worked with 32 bit.
Alternative I have mounted both disks and via another linux partition I have used:
cp -rvbdR /source/* /target
both methodes worked with ubuntu 32 bit. With 64 bit ubuntu I can NOT get it to work. error message after booting the clone: /var/lib/gdm/.ICEauthoriy ..
I can see that /source/var/lib/gdm has different rights as /target - will be part of the problem.
This did not happen with the 32 bit ubuntu - but why ?

I would like to install ubuntu 10.04.2 LTS in my desktop-pc. It boots, I select time zone and keyboard layout, but then it could not see my hard disk, so i cant go further.
But i can see the disk in console while typing:
Code:
# sudo fdisk -l /dev/sda
and I can also make changes in disk such as deleting all partions etc.

I'm going to replace the primary hdd of my box with another one of a different manufacturer, but of the same size (long story, never mind)
My current plan so I won't have to reinstall my system is booting from a Ubuntu CD (or USB stick, whatever) and doing
Code:
dd if=/dev/sda of=/dev/sdb
(If sdb happens to be a few megabytes smaller it doesn't matter, the last partition is not important)
Now my questions:
1. Is this going to work? Is it a bad idea?
2. Should I use any parameters for dd, for performance? Like setting bs (or something) to a bit smaller than the both HDD's (equal) cache size?
If that matters, the hdd contains both NTFS, ext3/4 and reiserfs partitions. I use grub to boot Ubuntu, WinXP and Win7.

I'm running ubuntu 10.10 on my Toshiba Satellite L645 laptop. Few hours ago, when my laptop was in screensaver mode, i couldn't login again, it was just blank black screen So i switch to terminal 1 by pressing Ctrl + Alt + F1 and login from there. Then i restarted by "sudo shutdown -r now". I did this a few times before and it's no problem. However, this time when the computer boot, I got the errors like :
---many similar errors like the following line---
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have requested /sbin/init.
No init found. Try passing init=bootarg
and redirected to <initramfs> prompt
So i googled and tried the liveCD and try to fix the hard drive with fsck. My partition resides on /dev/sda1 and using ext4
[Code]...
That's 3 blocks of information i got by following instructions on the IRC channel. I just forgot to paste the first command and now can't remember what it is

I just bought a western digital of 3 TB. Unfortunately Gparted gives error. Gparted can create a about 2TB+1TB, but when it is the whole disk, it does not work.
I tried JFS and EXT4.
My kernel is code...

I have a 60GB hardisk, and try to install CENOS 5.5 HEL5.5 and Fedora13 on it. I partitioned the harddisk to 4 primary partitions like below:
Partition MountPoint Type
sda1 /boot ext3
sda2 VGRHEL LVM PV
sda3 VGCENT LVM PV
sda4 VGFEDORA LVM PV
I created 3 Volume Groups as you see up: VGRHEL, VGCENT, VGFEDORA; under every VG, i created 2 logical volumes ,just like below: VGRHEL=LVRHEL00(swap) + LVRHEL01(MountPoint: /) Below VG try to partition them the same as VGRHEL too. VGCENT=LVCEN00(swap) + LVCEN01(MountPoint: /) VGFEDORA=LVFEDORA00(swap) + LVFEDORA01(MountPoint: /)
I successed installed RHEL5.5 on VGRHEL, but when i try to use the same way to install CentOS 5.5, i got below error infromation: "Bootable Partitions cannot be on a logical volume" I don't why this happened, VGRHEL has logical volume too, but why i can install RHEL on it successfully.

I have a single SATA hard drive, not raided, with an XP partition on it. /dev/sda. I've already created an 18GB ext4 partition for Ubuntu and 2gb swap partition as well. For some ridiculous reason the Ubuntu 9.10 isn't even showing /dev/sda as an option to install to!
fdisk -l clearly shows /dev/sda there, and i gparted /dev/sda works like a charm. So why is the installer being so silly and not even allowing me to select it? And I can't go back and choose manual mode or anything, the installer jumps right from Timezone Settins into this partitioner screen. Here is a screenshot of fdisk -l clearly seeing the drive fine, yet the installer not showing it at all. This is one of the things that drives people away from Linux.. It never TELLS you what the problem is

and this is what I got

I decided to go for an encrypted home folder. It's really really cool that ubuntu offers the encryption now out of the box!
However it auto generated a password for the encryption for me. While the password might be safe, it is impossible for me to remember. And writing it down on a piece of paper, which I would then carry around along with my laptop seems to make the whole encryption obsolete...
Long story short: Can you pinpoint me on how to change the encryption password?

I want to get a program to check (a) hard disk and (b) file integrity. I have had a file - ODS spreadsheet accessed using LibreOffice - that appears corrupt. I have drilled down and down and eventually identified a corrupt component image inserted in a sheet.
The error that is thrown by LO is a "Error saving
the document FILE: Write Error. The file could not be written."
error. The thread can be read here... http://thread.gmane.org/gmane.comp.d...fice.user/9266.
What has confused me is that my machine can not save the file once a sheet is deleted. It is specific to a particular file. The file is stored on n ext4 disk mounted by fstab. I also share the file using samba. Regardless of how I access this file I get the error. If however, I access the exact same file using OpenOffice 3.1.0 OOO310m11 (Build: 9399) from an old Windows Vista Tablet and I can manipulate the file successfully - no error is encountered. I can also access the same file from another Ubuntu machine via NFS and Samba and both work. I am confused. I am beginning to think my disk is damaged or something. How do you check hard disks to verify that the disk surface is intact, and that the expected file sum value matches the value stored in the Linux equivalent to the FAT table.
I am using Ubuntu 10.04 LTS and all hard disks are formated with ext4. All formatting and management of the disks have been done using the 'Disk Utility' in the System > Administration' menu. If I look in gparted it will not check the disk the file is on stating "eslabel: no such file or directory... couldn't find valid filesystem superblock...". The filesystem mounts OK however without any errors. Another harddisk on the same system currently being used for backup does not even have the menu option for checking the disk highlighted.
What is the best way of verifying the integrity of the filesystem, actual files and the underlying physical media? I should point out it is only this single file that currently displays any issues. I either have a damaged disk, corrupt file or LibreOffice has a very peculiar bug that only appears in a unique combination of events just on my machine. As part of my investigations I have been updating ubuntu, reinstalled LibreOffice from their website and checked all dependencies have been met.

I have a small issue where an USB harddisk is not automounting. CD's, USB pens etc. are automounting without issues, so it is a little bit strange.I am mounting it with UUID, because I want the mount point to be the same everytime.As you can see from the fstab, it is NTFS.
dmesg
[92.388083] usb 1-1: new high speed USB device using ehci_hcd and address 4

My hard disk is failing, and I want to rescue the files from it before it is un-bootable. I was planning to do this by booting a live cd, making a .tar file of /, and then burning it to a cd or dvd. The disk is still bootable, but I'm getting warning messages that 73 sectors are bad. I have another hard disk ready to plug in, I just need to rescue the files, and then install Fedora 11 64-bit on the new drive, at which point I will overwrite / with the / from the .tar file.
Basically I was just wondering how to mount a hard disk to recover files from a rescue cd. I tried to make a .tar file of / already, but that failed because the system was active and changing the various system files at the same time that tar was trying to package them.

I have my harddisk partitioned with fdisk. It has seven partitions. I have some important data in my /home partition. The /home partition is almost full. I want to extend the size of /home. Mind you I'm not using LVM. Can I use LVM now and add another harddisk to extend the /home partition. Will I lose my data. Or do I have to re-install linux?

Long story short I have windows 7 installed and in an attempt to install ubuntu the existing partition table was erased. What's the safest method to mount an ntfs partition and back up files? Or even write a table to get back into windows to back files up?

I had ubuntu 9.04 on a laptop, and it kept crashing, so I removed the harddisk, connected it via a Sandberg Harddisk to USB stick, and it works when I connect it to another ubuntu (running from livecd), but some of the files are locked, and I cannot open them copy them or anything else. What do I do?

I use dual booting, vista ubuntu 9.10. I have just bought a new 1T external harddisk i have used it on windows to backup some files. Now I want to backup some documents in ubuntu, but the harddisk is not visible, I can't see it, ok I think the term in Linux is that it is not mounted. Is there something else one should do ?
