I'm currently in the middle of developing an automatic system which can provision Linux VMs automatically.Let's say I have a disk image which has a Linux distro installed on it. How would I change the root password on that, without having to boot the OS?It would be nice if I could just simply run passwd with some switch to point to the /etc/shadow file on the (mounted) VM disk image..
View 2 RepliesOk, so I have installed openSUSE 11.3 on my Lenovo Thinkpad T61p, setup the wireless adapter (why is this so difficult?) and installed a few applications. I do like the look of openSUSE but would like to check out a few other flavours. With my Windows 7 (can I say that here?) machines I can create a system image and a system restore CD with a fair amount of ease. Is there a similar process available for Linux?

View 4 Replies View RelatedBasically, I want to be able to create the perfect disk image of a CLEAN Ubuntu installed in a 30 gb partition. The problem is, if I install Ubuntu, then some drivers are installed automatically. I am using an old computer at the moment (my main is back at home) and I want to be able to create an image so that when I restore that image onto my main computer, it is not cluttered with drivers of the old computer. Is there a method that can be used for uninstalling drivers?
I am looking for the cleanest way to uninstall drivers, hopefully to the point where it will not leave any "residue" That is my first question. My second question (in general about disk image--I have never actually created nor restored an image): Can I create an image of partition A and restore the image on partition B? Basically, creating an image of one partition and restoring it on another partition. Or does it have to be restored on the original partition?
Also, what if it is the same scenario but partition B is a larger size? I know that if partition B is smaller, it cannot be done because the image is larger than the partition. Finally, can partition A be restored onto a different hard drive? I have yet to find answers of these questions on different forums in other sites (this is my 3rd try). I know that the Ubuntu community is extremely active and more than willing to share their knowledge.
Suppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk
Code:
dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.
You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.
Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).
At the Get Slackware page at the Slackware website it gives a list of addresses which when I click one of the addresses it redirects to another page with a list of mirror images. Which address and which mirror image do I need to work with Kubuntu 11.04 on my netbook so I can create a USB startup disk? With my connection speed these mirror image downloads take about an hour and a half and I cannot just be guessing which mirror image to download.

Currently, I'm just running Ubuntu off the cd. Having checked the "Ubuntu Software Centre" on my computer, I notice that it has Brasero installed, and I was wondering:
1) First off, where can I find it? (Is there a search function in Ubuntu like Windows?)
2) Is Brasero a good choice to create a disk image?
i am trying to create an image of Slackware OS but vmware is not able to detect the disk. it gives me below error, "Unable to detect disks or volumes on the source machine. Make sure that the source is a supported linux distribution." can some one tell me what do i need to do to create the image.

I have a CentOS 5.5 server that has just recently been updated to 5.6 running PostgreSQL 8.4 and Drupal for an internal website. The server is also acting as a shared network storage between the Linux server and Windows desktops with Samba.
I just recently purchased a license to run Symantec Backup Exec System Restore 2010 for Linux and the only operating systems that are supported are RedHat and Suse Linux.
Does anyone know of a nice open source solution that we can use to create backup images of the server?
In the event of a server crash, we want to be able to rebuild the server via a bit-by-bit backup image.
The CentOS 5.6 is 32bit

Now im doing it like this:
Code:

mkfs -t ext2 -F -m 0 -b 1024 -i 1024 initrd
But i would like to move to cpio, because with dd, if you add something new, you might need to change the count. Also cpio is used in distro's like Fedora and Ubuntu.
In our organization there are around 1000+ users are using mails. The mailing system is implemented under RHEL using postfix and dovecot. For user based quotas i have implemented Disk Quota. But the problem when i want to edit quota for multiple users with similar limits i'm doing "edquota user" for every users. It seems very difficult. Now I wanna know:
1. Is there any way to edit quota value for multiple users at a single shot?
2. Also there is any method to send alerts mail to the end users on disk utilization?

View 2 Replies View RelatedIs 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.
View 4 Replies View RelatedI'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.
Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?
I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?
When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).
I am in need of the instructions of how to create a boot disk for my RED HAT Linux Enterprise Server. I have a floppy drive also it this helps.
View 2 Replies View RelatedWe 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.

View 3 Replies View RelatedSo i've been battling this for a while now, trying all sorts of different options and searching the boards before I finally decided to post this.I can't make CDs or DVDs, so my only option is to mount the downloaded ISO file on my laptop with CloneCD, then set up PXE DHCP,TFTP server. This method works on other distros but this one in particular is causing me problems in the installer.
So here's the process:I copy the files vmlinuz and initrd from the ooti386loader directory to my tftp root directory.on the system I am installing, i run gPXE, at the prompt type vmlinuz initrd=initrd.I have tried a large combination of different options {install=nfs after I have been having trouble which I will get to later.
the kernel loads, the installer starts. prompts for "Please make sure CD #1 is inserted" naturally, i hit back and select NFS as the install source. It then prompts me for DHCP configuration and the NFS server IP and directory.I'm running an NFS v3 server (haneWIN NFS to be specific) and exported the mounted ISO (this case F) as /suse.
Is anyone aware of a way (or a program I can use) to write to an existing ISO image?To set the scene I've used APTonCD to create an ISO with all the programs on I want so that the next time I install Linux Mint (or Ubuntu) I can just put in the CD & install a lot of programs in one go with Package Manager. Thats worked fine & I have the ISO ready for CD but I would like a way to change it a bit so that I can add some of my own custom setup scripts (stuff to set up user accounts & so on) then every thing I need is all on one CD / DVD

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?
Noticed this in both Ubuntu 10.04 & now Mint 9, both Gnome. I didn't have PCLinuxOS2010 KDE installed long enough to experience it so I don't know if it's a property of Linux or part of Gnome.I have two users, both myself and my wife, and I noticed thatn I mount an internal SATA drive I can only see/access it under the user that mounted it. In order for the other user to see it I need to un-mount the drive. Drive is a 1TB SATA formatted NTFS.I can't imagine this is normal and the 2nd drive is shared for pics/data/etc. Strange quirk is that my install is on a partitioned primary drive, 320gb, that also has Windows on it so the OS must access the drive in order to boot - both users can see the mounted 215gb Windows NTFS partition simultaneously.Is there a setting that needs to be changed or is this normal?
View 8 Replies View RelatedI have a problem with the system backup. I need to create a system image using the command "tar", but my server has physical disks with LVM and I am executing "linux rescue" for recovering the linux image. After restoring the image on the new server reports "kernel panic", this is caused because the new server where I restored the image doesn't have LVM disks.
