Working with ISO Images in Linux

A very interesting type of disk images are ISO images.

Reading ISO images

• Mounting using Loopback filesystem
• Midnight Commander
  
• ISO images are readable by most archivers. For example RAR can read them and extract files from them.

Creating ISO image from a folder

• mkisofs  

• ISO Master Use ISO Master for Linux (open source). See ISO Master - Wikipedia

  ISO Master is very convinient for:

  - Creating or customise CD/DVD images

  - Making Bootable CDs/DVDs

Burning ISO images to CD/DVD

See Burning CD and DVD on Linux

I start maintaining yast2-repair and first bug which I start solving is that repair from DVD menu doesn't work same as from installation menu. Find where is problem and also test if fix is correct is not trivial. I describe below how to modify inst-sys on DVD or software on LiveCD.

I found useful information on our wiki – Creating modified installation system. But I don't want install from network, as it doesn't shown same menu as on DVD. I try use mkisofs, but it is not easy set same boot sector as have original iso image. And there I found good software – isomaster. This allows you to replace file on iso image and remember from original iso image where it has its boot sector. This iso should be easily tested in e.g. Virtual Box and I can verify, that my fix work before we release first DVD with opensuse 11.2. Just sidenote – linuxrc show warning, that your inst-sys doesn't match checksum.

Same way is possible edit whole LiveCD. Simple mount and copy content of live system to your disc and with zypper –root you can change software in your LiveCD. Then create squashfs ( I use mksquashfs live_root openSUSE-kde-11.1-read-only.i686-2.7.0 -no-duplicates -noappend ) and with isomaster replace file openSUSE-* and you have your modified liveCD.

Backing Up And Restoring Your Dedicated Server With SystemImager

HowtoForge - Linux Howtos and Tutorials

Version 1.0

This tutorial is based on the tutorial "Creating Images Of Your Linux System With SystemImager" (http://www.falkotimme.com/howtos/systemimager/index.php and http://www.howtoforge.com/howto_linux_systemimager) where you can find the basics about how to use SystemImager.

Now let's assume you have a dedicated Linux server (rented or co-location) that is located in some provider's data center which is normally a few hundred kilometers away from your office or home. Now you want to make an image of that system so that you have a back up in case your server crashes, you accidentally deleted all you customers' web sites, etc. (I'm sure you have enough fantasy to make up some horror scenarios for yourself here...). Creating such an image is no problem, even on a remote system that is in a data center, it is all described in the "Creating Images Of Your Linux System With SystemImager" tutorial.

But how do you restore such an image? That's the crucial point. The methods described in the "Creating Images Of Your Linux System With SystemImager" tutorial all require that you have physical access to your server and that your server has a floppy drive or a CD-ROM drive. But your server is a few hundred kilometers away, and nowadays only few servers have a floppy or CD-ROM drive.

There is a solution, the only requirement is that your dedicated server has some kind of Linux rescue system which is a feature that normallly comes with dedicated servers offered by one of the big hosting companies. It basically works like this: your hosting company gives you the login to some kind of control panel where you can see a lot of information about your server, e.g. traffic consumption in the last few months, documentation, passwords, billing information, etc. There will also be a page that lets you select the boot mode of your server, i.e. normal system boot or rescue system. If you select rescue system, the server will boot into the rescue system which you can use to repair your normal system. It is similar to your Linux machines in your office or at home where you use some kind of Linux live-CD (e.g. Knoppix) to repair your system.

Now in this tutorial I will demonstrate how to restore an image on your dedicated server on the basis of a dedicated server that the German hosting company Strato gave to me 3 months for free in order to write this howto. Many thanks to Strato for their co-operation!

If you have successfully tried the methods described here on other hosters' dedicated servers please let me know! I will mention it here.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.

How to Write ISO Files to CD covers both ISO recoder (see below) and Nero.

ISO Recorder v 2 http://isorecorder.alexfeinman.com/isorecorder.htm

Welcome to the ISO Recorder download page. ISO Recorder is a tool (power toy) for Windows XP, 2003 and now Windows Vista, that allows (depending on the Windows version) to burn CD and DVD images, copy disks, make images of the existing data CDs and DVDs and create ISO images from a content of a disk folder.

ISO Recorder has been conceived during Windows XP beta program, when Microsoft for the first time started distributing new OS builds as ISO images. Even though the new OS had CD-burning support (by Roxio), it did not have an ability to record an image. ISO Recorder has filled this need and has been one of the popular Windows downloads ever since.

With an advent of Windows XP SP2 and Windows 2003 the version 2 of ISO Recorder has been released, which introduced some new features including ISO creation and support for non-admin user.

Finally, in Windows Vista it became possible to address another long-standing request and provide DVD burning capability.

Since the very beginning ISO Recorder has been a free tool (for personal use). It is recommended by MSDN download site along with Easy CD and Nero and is used by a number of companies around the world.

Download

• ISO Recorder V1 - for Windows XP Gold (no service pack) and Windows XP SP1

• ISORecorder V2 - for Windows XP SP2 and Windows 2003

• ISO Recorder V3 - for Windows Vista (Beta 1)

• CreateCD - command-line CD burning tool for Windows XP (all versions), Windows 2003 and Windows Vista

CDBurn.exe

CDBurn.exe from Windows Server 2003 Recourse Kit (free download; see Download details Windows Server 2003 Resource Kit Tools for more info) is a command-line ISO CD-ROM Burner Tool:

ISO CD-ROM Burner Tool (CDBurn) is a command-line tool that allows the user to write (burn) data images from image files located on the hard drive to compact disc (CD) recordable (CD-R) and CD rewritable (CD-RW) media. The data image can be any kind of data, even raw data. This tool can also be used to erase CD-RW media.

CDBurn allows users to burn image files containing any data, such as file systems like ISO9660 (Level 1, 2, or 3), Joliet, Universal Disk Format (UDF), or a combination of file systems. CDBurn's default mode is Track At Once (TAO). The tool also supports writing in Session At Once (SAO) mode, but not all drives support writing in this mode.

CDBurn automatically appends a postgap of 150 sectors prior to closing the disc. The appending of the postgap can be overridden by using the /imagehaspostgap option. The tool always finalizes the disc. This means that you cannot add any data to the disc after writing.

CDBurn writes data images to CD writable media from International Organization for Standardization (ISO) image files created by a variety of tools. One of these tools is Oscdimg.exe (available in the Microsoft original equipment manufacturer (OEM) preinstall kit (OPK)). Any other product that creates an ISO image file can also be used.
The following are the system requirements for CDBurn:

• Windows XP Professional or Windows Server 2003 operating system
• A CD burner

Files required:

• Cdburn.exe
• Mountvol.exe - an operating-system tool used to obtain volume names

Example:
To burn a CD from an image file when a drive letter is assigned to the CD burner type the following at the command line:

cdburn.exe d: c:\iso_2003.iso

Press ENTER. Output similar to the following is displayed:

Number of blocks in ISO image is 2a4e2
- 100.0% done
Finished Writing
Synchronizing Cache: burn successful!

Notes: The drive letter assigned to the burner in this example is D and the image file being written is located at c:\iso_2003.iso

The default burn speed for this tool is 4x with the maximum burn speed being determined by the speed of the burner. Use the speed parameter to set the burn speed. The max parameter sets the burn speed of the CD burner to maximum.

DVDburn.exe

ISO DVD Burner Tool (DVDBurn) is a command-line tool that allows the user to write (burn) Digital Video Disk (DVD) images from image files located on the hard drive to Digital Video Disk (DVD) media. The data image can be created by any program capable of producing DVD image files. You can also use this tool to erase DVD media.

• DVD-R (DVD Recordable) DVD-R is a write-once, read-many storage format similar to CD-R and is used to master DVD-Video and DVD-ROM discs. Write-once media (of any type) typically offers higher compatibility with older drives and consumer devices.
• DVD+R (DVD Recordable) DVD+R media is write-once media. Write-once media (of any type) typically offers higher compatibility with older drives and consumer devices.
• DVD-RAM (DVD Random Access Memory) DVD-RAM is a cartridge-based rewritable DVD disc designed for recording and playback. DVD-RAM acts just like a removable hard disk. DVD-RAM bare discs are fragile and do not guarantee data integrity.
• DVD-RW (DVD Rewritable) DVD-RW is a rewritable (erasable) DVD format that is similar to DVD+RW but its ability to work as a random access device is not as good as that of +RW. You can rewrite this media many times. It has a read-write capacity of 4.7 GB. It is the only media that supports the /ERASE parameter.
• DVD+RW (DVD Rewritable) DVD+RW is a rewritable DVD format with full random data recording support. It has a read-write capacity of 4.7 GB. DVD+RW media is always formatted as part of the DVDBurn process. The formatting takes the place of an erasure, so an /ERASE switch is neither required nor supported. You can rewrite this media many times.

• Windows 2000, Windows XP Professional, or Windows Server 2003 operating systems
• DVD Burner

• Dvdburn.exe
• MountVol.exe - used to obtain volume names
