I am running RHEL 5 on Vmware Workstation. That is i inslled Vmware Workstation on windows 7 and then in Vmware i installed RHEL 5 as a virtal machine. By mistake i made some wrong entry in my /etc/fstab file that is i was trying to automatically mount one folder under another folder. My syntax was wrong. So when i restart my RHEL 5 , at the boot time due to wrong entry in /etc/fstab system is giving file system error as follows:
Checking filesystems
fsck.ext3: Unable to resolve 'LABEL=/home/download'
fsck.ext3: Unable to resolve 'LABEL=/var/ftp/uploads'

I have worked on Xen which is being shipped with RHEL 5.4, Is it possible to install Xen hypervisor directly on bare metal, so that we can save resources. I searched in Xen Official site, but could not recognize the product that can be directly installed on bare metal like VMware ESX.

Image Hard drive Ubuntu Operating system 9.10 Complete back up and restore. Changing over Hard Drives need a complete back up not just save files. So the image can be restored on any hard drive that restores the computer to its original state before it was imaged.

I installed RHEL 5 today and set my network. Did it as follows:Eth0 connectionPrimary DNS 192.168.1.1When I click on Activate, it says:8139too device eth0 does not seem to be present, delaying initialization.This message shows no matter how many times I log out or restart.I don't know what the heck is the problem. I've done the essentials but still it's not working. I looked up on the net but people were saying things like ifconfig and lspci, and at the end still weren't able to solve it. I don't know all this since I'm new to Linux. Another important thing...after facing this same problem some time ago, I installed Centos which asked for internet settings right at the time of installation. And after logging in for the first time, I was able to use internet without any problem. How come internet works on Centos (which is a copy of RHEL) without any problems, but not working on RHEL itself?

I have 4 different servers with exactly the same hardware. I set up one of them to have a centos install with all the basic stuff I'd like running on each one. I then created an image of the harddrive with the operating system, and stored it on an external drive. I used dd to copy the external image to one of the new machines. It worked fine, everything booted up as normal and with a few tweaks everything was great. The problem is that the drive is rather large (500gb) and it takes days for dd to copy it over. I decided to try a different route, I booted to a usb (using the linux distro on the ultimate boot cd pre-loaded with gparted). There are two partitions on the external drive, a small (100mb) partition which can easily be copied over with gparted, and the larger 480+gb lvm partition.
Gparted doesn't support lvm, so I used fdisk to create a new lvm partition on the new machine, and then pvcreate/vgcreate/lvcreate to re-create the same volume groups/logical volumes that are in the image on the external harddrive. I rsync'ed all the information over from LogVol00, and made the same swap partition LogVol01 (which took WAY less time). I disconnected the hard drive and renamed the volume group to VolGroup00 (initiall I named it differently, since linux doesn't like having the volume groups named the same). I can mount the LogVol00 partition and see all the files as they should be. But when I try and boot up, it doesn't even go to grub, I just end up with a blank screen and blinking cursor. How to make the drive bootable? Alternatively, a better strategy than using dd to restore this image??

My laptop is Windows XP Fedora 11 dual boot. I am replacing it because of a defect. The original laptop is fairly new so I could simply start from scratch and setup everything again. But I was thinking there might be a way to do an image backup and restore. My new laptop will be identical to the old one

I am having a problem finding a piece of software. I've searched a lot and still have not come up with an answer. My situation is as follows: I have an image file the I wish to restore to my USB flash drive but so far I've had no luck doing this. I was wondering if there was a program/command that could help me restore the disk image.

I have a Debian Jessie 32 bits machine with standard partitions : one EFI, one for the root system and a swap.
I did a dd image backup of it hard drive thinking i would be easy to restore it or clone to another device... but it seems it is not that simple ! My PC won't boot : no bootable drive found !
I did the same once with a 64 bit Debian Jessie which i fixed using an ubuntu live CD with boot-repair, but here with the 32 bits version it doesn't work : it keeps saying i have an EFI incompatible partition and i should use a 64 bits linux...
Note : i boot-repair from a 64 bits ubuntu live cd. Should i use a 32 bits version ? Because i can"t make a 32 bits Debian live CD to boot, usb key won't show up in boot options (32 bits install CD works fine)
I ha read some things and tried some others but nothing works
Grub and EFI are really obscure for me...
How could i fix my debian 32 boot ?
Or how can i properly clone my debian 32 on other PC ? am i missing something using dd ? should i use another tool ?

I have recently setup a dual boot system that consist of Windows Vista and Fedora 12, I am looking for a solution that will allow me to create an entire restore image for both OS's on an external hard drive. I am looking for something that is easy to use, stable, and free. I have looked at clonezilla and have used Norton ghost 2003 in the past which is not supported with Windows Vista.

I'd like to create a boot floppy or CD to restore an image from a harddisk over the network, and it should work possibly automatically.
A normal, non-IT user should be able to do it in our branch abroad.

If I partition and install Ubuntu on part of my pc's hardrive, would the digital image factory-settings restore feature still be available? If so, and if used, would a factory restore use 100% of the hardrive and erase the Ubuntu install?

I used Clonezilla an older version not the latest to backup an entire NTFS Windows XP drive to DVD last year. I have a series of three (3) of these DVD's but now cannot restore the backup image back to the same PC. The problem is that when booting with Clonezilla I don't have an option to restore from a CD or DVD drive since the computer comes with two working CD/DVD drives that are detected by the BIOS when the POST is displayed. I used one of these drives to boot with Clonezilla and the other one containing the backup image Disk 1 of Disk 3. Clonezilla only detects the two hard drives and a USB drive which is removable. Is there a bug in the restore process because it allowed me to backup the entire image of the hard drive onto a DVD last year but this time around there are no CD or DVD drive options available to choose other then the CD drive Clonezilla was used to boot up.

I'm playing around with the RHEL 6 install so as to create a minimal install image to be used as a generic node for a cloud. I posted this in the security section as reducing the number of services etc seems like a security activity, i.e. reducing the running processes to minimize the attack surface.
Anyways, looking through linux from scratch etc, and the NSA hardening list I'm a bit overwhelmed. Anyone have hints on any good documentation saying what is really needed for a basic system with network/ip/arp/eb rules? The RHEL 6 minimal basic puts in a c/c++ compiler along with other things. that seems unnecessary to me for a basic minimal install.

I do computer forensics here in Afghanistan and I am trying to keep a clean image of a dual bootable hard drive. Here is what I try to do...
1. Boot into UbuntuLiveCD
2. I run "sudo dd if=/dev/zero of=/dev/sda conv=sync,notrunc bs=64K" to wipe the drive with all zeros.
3. I then install Windows by creating a new partician about 50GB.
4. I then install Linux by creating a partician in ext4 mounting it at '/' in addition I create a swap partician.
5. Next configure everything just the way I want it. I install all the drivers and software I need for my windows partician and build out the remaining part of the disc as a "data drive."
6. Then I use "dd" again to try to image my "clean slate" of a system. Remember I am dual booting. I dd the /dev/sda and gzip it.
7. When I go to restore it, I boot from the live CD again and unzip ig and "dd" it back onto /dev/sda.
8. I run fdisk -l and I get:/dev/sda1 * 1 6375 5120000000 7 HPFS/NTFS/dev/sda2 6376 11724 42965842+ 83 Linux/dev/sda3 11725 12453 ...... 82 Linux swap / Solaris.This means to me that it can "understand the file system"
9. But then when I take out the Live boot CD and try to get my "clean slate" machine back, the system goes into Grub Rescue mode with a grub command line "grub rescue>"
10. I tried using the tutorial on Grub2, but...
a. It would not understand the command "linux"
b. When I try to do insmod, it says it doesn't recognize the file system.

i'm wondering if it's possible to restore the original image file that you have hidden data in with steghide. The basic Idea is you have a photo using gpg sign it and then embed the signature. then remove the signature at a later time and check it with the signature. I hope another "inverse" algorithm doesn't need to be written to undo the first (if a "inverse algorithm is possible). This assume you already have the pass phrase or that there is no pass phrase. I already know how to retrieve the original file just want to remove the hidden data from the Image and restore it's attributes.

I have an Ubuntu server and i've installed drbl-clonezilla to clone and restore pc, I have a 40 gigabyte image to be deployed on other pc's with larger hard drive ex. 160 GB or 240giga, my problem is that when I deploy the image on a larger disk I end up with a disk with a partition of 40 GB and the rest unallocated, how can i restore the the disk and use full disk space, the goal is to automate the process. In clonezilla-drbl there is the possibility to start a "prerun" and "postrun" fonction that could help complete the deployment process.

Am quite new to Ubuntu (10.04) and have recently reinstalled XP. I want to make an image of my windows partition to save time and effort when wanting to restore this. I read the Ubuntu documentation on Drive Imaging [URL]..community/DriveImaging and am wondering if I've done things ok?
I've booted using the Live CD. Windows is on sda1 and is a 50GB partition. I have a hidden ntfs partition on the same hard drive at sda9 of 10GB. The first time I tried this I got an error regarding my output file saying "Not a directory". I'm assuming that was because I hadn't mounted sda9. It also reported an error saying permission denied on sda1. I then mounted sda9
Code:
sudo mount /dev/sda9 /mnt
I then changed to root as I thought not being in that was why I was getting the permissions error.
Code:
sudo -s
I've then done the following;
Code:
dd if=/dev/sda1 bs=1024 | gzip > /mnt/sda1.bin.gz
The terminal window is just showing a flashing cursor in the bottom left corner under the above command line input. Is the fact that my mount partition being smaller than my windows partition going to cause a problem or will gzip solve that? My Windows install occupies about 7.5GB of the 50GB partion.
I'm not sure if dd is just taking a long time to complete the task???

I plan on creating a backup of my Windows installation using DriveImage XML (unless you have a better idea ) then wiping my hard drive clean, creating a new partition for the backup install to live, and then installing Ubuntu on another partition. Is there a method of restoring my Windows backup to partition 1 by using the live cd? Then of course I can install ubuntu to partition 2.

I have a Dell windows 7 laptop that suddenly is unable to boot: stops at a blinking cursor line after the Dell logo appears and is unresponsive (I can load the BIOS (F2) and the boot menu (F12) before the lock, but that's it). Unfortunately, I don't have access to the Win7 install disc, so can't use Microsoft's recovery tool.

I've got a program that was working fine in RHEL 5.4. On my RHEL 6.1 test server, the program failed to pick up the files on my samba mounted folders. I went through the code and found that S_ISDIR returns the folder in the mounted drive as FALSE. It has no problem with files on the local filesystem though. Any suggestions on how to fix this?

I have an RHEL 4 server now running 2.6.9-89.0.18. After installing the kernel and rebooting to make this the current kernel, the grub menu to choose the kernel failed to offer a countdown and did not choose the kernel as it should have. I had to manually select the kernel.I inspected the grub.conf file and could not find any clue as to why it didn't work. The timeout directive is there, and the syntax matches other systems we have with the same kernel and OS.Can anyone provide any insight as to what else (other than a typo on the conf file) would cause this?The only difference between the way the kernel update (and the subsequent changes to the grub conf file) took place was a manual install of the RPM on the affected system, versus pulling it down from RHN using up2date.
