General :: Can't Copy The Disk Image Over To Ext3 Partition
Jan 6, 2011
I recently installed Linux to run a few Linux based tools on a disk images I have, and I can't seem to copy the disk image over to my ext3 partition.
The particular distibution I'm using is BackTrack 4 r2, which is Ubuntu based. I can't seem to find specifically which version of Ubuntu is being used. The disk image is 108GB. It is currently located on a NTFS partition on a SATA hard drive connected directly to the computer. The ext3 partition is located on a second SATA hard drive connected to the same computer. It has 200GB total. I do not remember exactly how much free space it had but "df -h" showed a lot more than 108GB. The computer has 4GB of RAM and I gave it 8GB of swap space.
At this point it has been running for more than 12 hours. This is far longer than I would expect it to take had I been copying the file under Windows. How ever I do not have much experience with Linux, so if it's supose to take this long please let me know. I am planning on letting it run until I wake up tomorrow.
"cp -v" hasn't been very verbose at all. The only sign I have that indicates the computer is still trying to do something is the HDD light on my chasis that has stayed lit this whole time.
I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.
i m not able to copy a file over 16 gigs on an EXT2 or EXT3 partition. Is there a way to do this. I even tried to split my iso file too. I splitted my iso file in 4 files then copy them on the ext2 or ext3 partition. But as soon as I was trying to join the files together it never went over 16 gigs. Actually it stops at 16,843,020 kb exactly. is there a limit for those partitions or is there an another way to see my 20gigs iso file in one piece?
I need to copy data from a single HD, which used to be part of a Linux RAID 1. I've googled around, but can't find any clue how to mount partitions from this single HD.
Background: The HD comes from a linux based NAS box Synology DS207+. The NAS uses ext3 as filesystem. Both NAS disks are fine, but the other NAS hardware is dead and not worth repairing or replacing.
I have a lv image = /dev/vg0/server01. I create a partition using fdisk /dev/vg0/server01. Now, i have a partition under lv image = /dev/vg0/server01p1. how do i format /dev/vg0/server01p1 to ext3, it seems that the system doesn't recognize the partition under /dev. the purpose of this is to fully restore filesystem on domU (xen).
I downloaded an raw SD card image that has two partitions. It caused some file system errors when I tried to dd it directly into an SD card. I am not sure if the card is defective or the image. Is there a way to examine this image without writing it to a physical card? Like trying to mount the partitions separately or checking the tables?
I have a broken DVD drive and no others available right now to burn a DVD iso to so I'd like to use a empty hard disk instead.
I've tried Unetbootin but that only copies a few megabytes of files - the rest of the image data in the ISO is ignored.
I have verified the ISO is valid and working with VirtualBox. It's MD5 hash is also as expected. But I need to boot at the real bios not an emulated one.
After I burn the DVD image, I put the disc on the computer and boot. The installation screen appears, the acknowledgement screen appears, then the installation checks my system and gives me a yast window with an error about something related to URLs and repositories. I cannot continue with the installation.
I am 100% new at this and thought it would be as easy as installing ubuntu (which I installed on a laptop and works flawlessly).I am trying distros and opensuse is compatible with my video card right out of the box apparently, so that's why I chose it for my desktop.Do I need to copy the dvd image to the hard disk of the computer I want to install opensuse on, and use the dvd to boot as well?
I have 2 partitions on my hard disk1. sda1 is ext3 partitoins with MINT linux2. sda2 ntfs partitions with my files and movies I want to copy, make backup of my sda1 partitions and store it to file (image) in some folder in sda2.In windows I have made that many times with Acronis and ghost, but I dont know how to make it in MINT.Is there some manual that explain that.
OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?
I spend the vast majority of my time in Ubuntu, but every so often I still encounter the odd errand that requires a free copy of Windows that came with my hardware.
So I have Windows 7 on my laptop which I like slightly better than XP and a whole lot better than Vista. I am not in there a lot besides that its required for a web design class and sometimes for a few stubborn games, but I would very much like to copy my Windows 7 partition to a 100gb partition on my TB HDD.
How do I do it? Keep in mind, I am barely two tiers above noob on a scale of 1 to 20. I am working on it though.
I also want this partition to be bootable. I dont care if I lose the rest of the data on the disk. I want to redo everything anyway. I definitely want it to boot though, not just for the data to exist.
Is there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.
Greetings from Greece. I tried to install opensuse 11.3 in an empty disk . Unfortunately the installation progress stops in 88% and the message error says "error copy live image to the disk". I have burn two different cd but the result is always the same.Is it a hardware problem or the cd is not correct?I had the 11.2 version in the same pc without any problem for a long time.
I have a NAS from WD that runs some stripped down flavor of linux. The NAS has one USB port at the back which can be used to expand the storage. If I plug in an external disk formated in either NTFS or HFS+ then the system automatically mounts the disk and shares it over samba. If I plug in a disk that is formated in ext3, the disk is recognized but that's about it. It doesn't mount or get shared or anything. I have tried asking WD about this and I have tried asking google. But after two days of searching I am turning here for some more expert advice.
Here is what I've managed to figure out so far.
If I check dmesg before and after plugging in the ext3 usb disk I have found out that these lines are added to the log:
Code:
I have tried googleing those last two lines but I haven't found any info that I can make any sense of.
If I run the command "mount -a" I get the following messages from the shell: "mount: Cannot read /etc/fstab: No such file or directory"
Hover I am able to mount the ext3 disk manually. First I get this info from fdisk
Code:
And then I run these two commands:
Code:
This makes the usb disk visible in the shell, but since this is a NAS, it is kinda useless as long as it doesn't show up in samba.
Since I'm pretty new to linux I don't know what to try next so I'm hoping for some advice as to what I can do to make the ext3 usb disk automount.
S.M.A.R.T.tells me my primary fedora drive has lots of bad blocks,so I ordered a used identical drive from ebay.I want to do the very basic process of making a full backup of my existing drive - so as to replace it with a more or less identical replacement. Logically identical - not necewsarily sector to sector identical.im not literate in unix and its children - and seem to find a plethora of descriptinos of how to do what I want to do. which is
1. format the drive - what you may call low level format - ie op sys independent.
2. create a partition system compatible with my existing disk.
3. copy everything from my existing disk to the new disk.
4. put existing disk on the shelf as a backup and start to use new disk.
A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.
I got a new hard disk for my laptop and I want to move my Gentoo installation from old HDD to new.
Most simple guides recommend use of dd to copy the whole partition byte by byte.
I'm moving to the new drive because I don't have enough space on the old drive, so I don't want to simply clone the partition. Instead I need the destination partition to be bigger. Would dd work well in that case?
Assuming that I use same partition types on the new drive, would I be able to use simple cp with appropriate settings?
is there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?This would mean that I need to have root privileges on every machine... which I may not have in some cases.I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive.
following problem. A friend phoned me in despair. Her Ubuntu didn't start any more - ASUS-Laptop switched on stops at a ramfs-prompt. I started Puppy-Linux from DVD-Drive. Worked fine. But puppy can't mount her /dev/sda1 partition either. At least you can see that the partition is still there. Fsck stops with an error. May be the initial problem is a sort of bad hardware by which bad bytes were written to the hard drive. Hard drive and/or memory could be replaced but not the data.
I've been trying to figure out how to move /home to the other partition that exists on my computer, however it's ntfs and turns out it's impossible to move my /home there. So how do convert that ntfs partition to ext3, I don't mind loosing data that's in that partition. [url] is the partition I'm talking about. So what's the best way to do it ? If you write what commands I should use please include partition names.
I am facing a serious problem.I installed UBUNTU 10.04 and encrypted it during installation. I accidentally erased some of the necessary files from root folder. now the the OS is NOT booting.luckily i still have the encryption key i have some important documents in that drive (desktop folder).
PS: I have tried to run Live Ubuntu it shows the Root, but it does not enter any of the folder.
I usually repartition a disk by backing up, deleting the partitions, formatting them and repartition. I just did a 200 gig backup (so i am safe) and i want to join 2 (ext3) partition together, sdb1 (data4) and sdb5 (data5) into one big partition. Is there a way to do it without scraping the data in sdb5 (data5). It would save me from rewriting the data back to that new partition (200 gig is time consuming).
I have an HP laptop with a recently installed copy of Mint 8 KDE Community Edition. I created the initial admin user account ("joseph") when I installed.
I had an existing home directory under a different name from another installation, so I added a user with that name ("joe") and imported a copy of the original home directory. The user "joe" didn't have the same admin privileges as the initial "joseph" account, so I added "joe" to the sudoers file and the same groups as the initial admin user.
Everything works perfectly under this arrangement, for the most part. Now here's the problem:
I have a T-Mobile G1 phone that uses Android. I've rooted and ROM-modded the G1, and have the microSD card in the phone set up with two partitions. The vfat partition stores all the photos, music and other stuff the phone needs. The ROM mod allows me to store apps on the SD card, so that second partition uses ext3 for its file system.
When I'm logged in as the admin "joseph" account and I insert the SD card in the laptop's card slot (or plug the phone into the USB port), the SD card can be mounted, and I have full access to both card partitions. I can see all folders. I do this to backup the contents of the card to an external drive (especially the apps in the ext3 partition, since that's been trashed on me once before on the phone).
However, when I log in as "joe", I cannot view the contents of the ext3 partition at all. I can see the vfat drive fine, and the ext3 partition mounts, but with user/group "joseph/joseph." When I open Dolphin to view the mounted ext3 partition, I get the error "could not enter folder /media/disk-1" at the bottom of the view window in Dolphin.
Here are the relative entries returned when I run "mount" to view the mounted drives:
/dev/mmcblk0p1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,uid=1001,utf8,shortname=mixed,flush) /dev/mmcblk0p2 on /media/disk-1 type ext3 (rw,nosuid,nodev,uhelper=hal)
Note that the uid listed on the vfat mount is 1001, which is the gid for the "joe" account.
I know there must be a configuration setting somewhere that will allow the ext3 partition to automount under the "joe" user account. I suppose that using the admin account to change the permissions would be the easy way to do this, but there must be something that would do it automagically. I've ripped through all the config files I can find, but can't seem to find anything that would help.
All I'm looking for here is enough access to be able to copy the directories on that mount to my external drive.
I have a 160GB harddrive which I installed a F12, would like to upgrade to a bigger drive, but I hate to have to re-install everything.
Recommend a good disk copy utility? The utility should be able to not only copy files, but boot sector and everything. So I just need to make a copy, change my BIOS to boot from the new drive and run everything as before.
Does anyone know if this is possible? I am attempting to copy one "master" hard drive to two or more "destination" drives. I hope to use the DD command because the master drive is encrypted and I need to make exact copies to "destination" drives.
I have used dd if=/dev/sda of=/dev/sda and it works for one-to-one operations. I tried dd if=/dev/sda of=/dev/sdb of=/dev/sdc but the command skips the of=/dev/sdb and copies to sdc....I knew that was going to be too easy
