I need little help on live disk creation and disk image backup.
Can I create live disk using my hard drive installation? If yes then, can I restore the fedora from the live disk to the hard drive. I mean to say that from that live disk can I install fedora again in my hard drive.
Second question is, if I create the disk image of my hard drive( including ntfs & FAT32 partition) , can I restore it in a blank drive. If so , then can os will be restored also?
I'm a Linux newbie and are trying to install F13 from bootable USB onto the HD of a DELL mini netbook. I've followed the install wizard's defaults including the "Use All Space option." The install errors out at about 20% of progress during the "Copying live image to hard drive" process. The error dialog is as followed:"There was an error installing the live image to your hard drive. This could be due to bad media. Please verify your installation media..." and it comes with options to Exit installer or Retry. I have since retried and restarted several times and still came to the same error. FYI, I've initially attempted to install F13 to the HD over an existing Windows XP.
I'm using a dell XPS M1530 laptop with windows vista and ubuntu 10.04. Last week when I turned on my laptop I got an error saying internal hard disk not found. When I called dell support, I have been told that my hard disk is dead. I have few important stuffs in my hard disk for which I don't have any back. So I tried using ubuntu live CD to back up my data as in the link below.[URL]..I'm using ubuntu 10.04 live CD(64 bit). When I go to my places after booting from the live CD I can't see any partition showing my hard disk. I can see "Computer". When I go in it I can only see "File System" and nothing related to my partitions in my HDD. What should I do now? Do I need to mount my hard disk or is my HDD completely dead?
We have some servers that run in very harsh environments (research vessel) that need to have high-availability.We have software RAID 1 for some measure of resiliency, along with proper data backups (tapes etc), however we would like to be able to break out a new server and re-image it (including RAID setup) from a known good copy if the hardware completely fails on the production box. Simplicity of the process is a big plus.I am interested in any advice on the best way to approach this. My current approach (relatively new to Linux administration, totally new to MDADM) is to use DD to take a complete gzipped copy of one of the RAID'ed devices (from a live CD): ode: dd if=/dev/sda bs=4096 | gzip -c > /mnt/external/image/test.img then reverse the process on the new PC, finally using Code:mdadm --assemble to re-create and re-build the array.
I am having trouble both installing or even just booting the live CD. I have to interrupt the boot to give the nomodeset boot option.
Once I get the Ubuntu splash with the oscillating red and white dots for several moments, I get the Busybox with the error message "Unable to find a medium containing a live file system"
If I do a dmesg I then see a lot of sr0 errors. I have an onboard SCSI controller but no scsi devices. I am not sure if this matters.
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 need to expand a 15GB xen disk ".img" to 50GB, it's got centos as the guest O/S.
I've been googling and there are alot of results but I'm still having trouble.
I don't remember if I used the default LVM partition scheme or if I did a FS. In fdisk it says linux partition but that's it.
I did the dd and cat method but fsck is complaining like usual.
I dd a file called tempfile and the append it using cat tempfile >> my.img then did resize2fs -f but it error out with "Bad Magic number on super block."
I have fedora on a parition. the root / folder, and a swap. I wanna try other linux, but i dont want to delete my Fedora. So I want to back up my Fedora whole disk data, can I create a disk image for Fedora so that later I can Restore it?
just got Fedora 15 up and running and i have a 2nd internal HDD which i want to use for backups only, how do i format it exactly, mount point? file system? I've tried few options but when i try to point at it with Deja Dup i can't access it?
Is it possible to mount a virtual disk image like qcow2 as a rw filesystem? I would assume guestfs could do it, but I couldn't figure it out from the man page. Basically I want to be able to read and write to the contents of a Windows virtual machine, just like I mounted a physical disk.
I am developing for a Linux based device for which the HOT PLUG option is deactivated. As part of optimizing the code, we also don't want to create device files for unused devices. We understand that both USB attached and fixec SCSI hard disks would create device files like /dev/sda,/dev/sda1 /dev/sdb, /dev/sdb1 etc. Is this understanding correct?
In the case of USB attached SCSI devices, would driver create this device file entry? How is it created? Can somebody please tell me how it is being created automatically. In case I attach a fixed SCSI hard disk before boot up(and create device file /dev/sda1), would USB SCSI device driver create device files starting from /dev/sdb, automatically.
I'm getting error from KVM when i try to create new machine. I have install group Virtualization. From gui virtual-manager (after being asked for root passwd) tried to create new machine. When pressed on 'Finish' got this 'Permission denied' error: Code: Unable to complete install '<class 'libvirt.libvirtError'> internal error Process exited while reading console log output: char device redirected to /dev/pts/3 qemu: could not open disk image /sonik_data/software_archive/CentOS-5.5-x86_64-netinstall.iso: Permission denied

It's running as a root, what permissions we are talking about here? I'm running F14, kernel 2.6.35.10-72.fc14.x86_64, libvirtd 0.8.3
This probably is something simple, and may have already been addressed on here.I have a 1.4MB floppy disk image file that I would like to mount as a drive.
I booted my laptop from the FC 13 Live CD.I'd like to mount the local disk while booted from the Live CD.In older versions of Linux, this used to be as simple as "mount /dev/sda2 /mnt/whatever".But, no longer Progress. When I do "fdisk -l /dev/sda", while booted from the FC13 Live CD, the /dev/sda2 partition shows up as "Linux LVM". My question: how can I mount the partition containing home directories from the "Linux LVM" partition?
I have such trouble with YUM: $ sudo yum update Total 807 kB/s | 192 MB 04:03 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Traceback (most recent call last): ..... File "/usr/lib/python2.6/site-packages/yum/sqlutils.py", line 166, in executeSQLQmark return cursor.execute(query) sqlite3.DatabaseError: database disk image is malformed
I already try clean yum cache and remove checksum data, rebuild rpm db, check / partition, but no luck, problem still occurs.
Any time I've tried to run 'yum search' or 'yum info' I end up getting a error "database disk image is malformed"
Code: $ yum info postgresql Loaded plugins: presto, refresh-packagekit Error: database disk image is malformed I am, however, able to update and install software without this error occuring.
I've tried the 'yum clean all", "yum clean metadata", "yum clean datacache", and rebuilding with "yum makecache", but still this problem crops up. As I understand it, the error message comes from something possibly not having been updated properly in one of the sqlite databases that yum stores information in. I probably could fix it if I knew which sqlite db that 'yum search' and 'yum info' hit.
I've run the install to hard drive program three times over and each time I get "disk boot failure". I believe I've got Grub to install to the mbr but I am not sure.
System: Barton 3200+ with 1GB of DDR1 Asus A7V333 High Point hard disk controller
other items
All the hard drives are hooked to the High Point controller. It recognizes all of them that have power hooked up and read/writes to them. Two have 98SE installs, the third is where I'm trying to install Fedora 12 to get away from some problems I'm having with 98SE.
The BIOS is set up to boot from the "SCSI device" which means it's booting from the High Point controller. The High Point lets me set a boot mark, which, when set to the Fedora drive, yields the disk boot failure no matter what I do to it.
I want to restore a HDD image I have to my laptop's HDD while booted off the Ubuntu Live CD.The laptop's HDD is unformatted and has no partitions.I expected this to work:$ sudo dd if=/path/to/backup.img of=/dev/sdaBut I'm tolddd: opening `/dev/sda': Permission denied.
