I have just reinstalled Centos 5.3 on a new harddisk. I would like to copy some files from another harddisk which is also install with Centos 5.3. I have followed some guide in the internet but failed to mount the old harddisk. I got "unknown filesystem type 'lvm2pv'" error when trying to mount /dev/sdb2.
Details:
I am using virtualbox to run windows xp.is there a way to access the harddisk occupied by linux and copy the information to the virtual memory in windows xp

Error mounting: mount exited with exit code 12: Failed to read last sector (1953525103): Invalid argument

I've got three disks together on a *home* server that constitute four LVs.The two are the root and swap LVs installed by the Ubuntu 10.04.2 LTS installer on the OS drive (250 GB VG: Beta). The third & fourth LVs I made of two physical volumes (640 GB and 200 GB VG: Data) and mounted each inside /torrent. All are ext4.
I'm migrating lots of large files from /home to inside of /torrent, but I'm seeing EXTREMELY slow speeds (700KB/s).I'll admit this is my first time using LVM, and I tried it only because of the numerous smaller drives I have sitting around that weren't getting used. I didn't expect such a large drop in speed.
Here's a more technical review of the setup:
Code:
me@Beta:~$ sudo pvdisplay
[sudo] password for me:
--- Physical volume ---
PV Name /dev/sdb
VG Name Data

I am using ubuntu but I am reading a windows harddisk via USB.Apparently some files does not appear and it cannot read zip files.
View 4 Replies View RelatedI'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 need to recreate in a local folder called /distro/fedora/ the full directory tree (including eventually hidden files, symlinks, etc.) contained in the .iso file just downloaded (Fedora-15-i686-Live-Desktop.iso).
I understand I can mount the ISO image using something like this:
mount -ro loop /path/to/image.iso /mnt
but then, which would be the best way to get a copy exact of what I see underneath /mnt in to /distro/fedora ?
cp, tar, clobber?
I am trying to replace an old, smaller, and dying laptop hard drive with a newer one, using a USB external drive. I first tried cloning disk to disk with Clonezilla, but it failed after cloning my root, swap, and /home directories it froze when it tried to reinstall grub. After 2x trying, I switched to dd, which I have never really used (I am fairly new to Linux in general). The actual command I used was:
Quote:
dd if=/dev/sda of=/dev/sdb bs=4096 conv=notrunc,noerror
All seemed ok and after approximately 2 hours my 80GB drive had been cloned onto my new 250GB, with dd giving what appeared to be a satisfactory closure summary. I tried to mount and access the drive from my external USB enclosure but could not view it, though the data is there, I believe, as the size and bytes show... The error that Dolphin is giving me is:
Quote:
error - wrong fstype, bad option, bad superblock on /dev/sdb1 Missing codepage or helper program or other error. When I installed the new drive directly into my laptop, it begins to boot (Sabayon 5.4, 2.6.35 kernel) but almost immediately I get (handwritten down, but this is close):
Quote:
detected real_root
mounting /dev/sda1 on /newroot failed: input/output error
!! Could not mount specified ROOT, try again
!! Could not find the root block device in .
[code]....
I am assuming that my issue has something to do with grub, and maybe specific UUIDs that don't match (?) but I'm not really certain. I have both Grub Legacy 0.9x and the newer Grub 2 installed (Sabayon is already moving over) but I still boot with Legacy, not with the new 2, as I don't know how to switch, and am not sure if I should yet. I thought that dd copied bit for bit, and I added the noerrorï just to try to get it all transferred, so I don't know what went wrong exactly, though something seems wrong with grub and the bootloader, I guess...
How can you create a script to move or copy files from a main directory into multiple directories below the main directory.
View 7 Replies View RelatedWhen 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.

View 2 Replies View RelatedDoes anybody here know a program (Linux-based or even Windows-based) which permits looking at the files structure of a harddisk in such a way that you can find out what file lies where on the harddisk?To specify further what I mean, back in the DOS days the Norton Utilities would show the distribution of files on a harddisk. It would show the harddisk as row upon row of rectangles, marked as used or not used, and the top left rectangles were the beginning of the harddisk while the lower right were the end of it.Now if a program put some files at the end of the harddisk it was possible to mark the filled rectangles and find out exactly which files were there.

View 2 Replies View Relatedhow 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 ?
