Warning failed while updating the boot sectors for disk1 partition1

The Linux Sysadmins Guide to Virtual Disks by Tim Bielawa is licensed under the Creative Commons Attribution-Share Alike 3.0 Unported License. I was motivated to write this book because I felt the quality of the information regarding commonly used functionality in virtual disk operation was lacking certain specific clear examples.

What I hope to provide is a book which will demonstrate the core concepts of virtual disk management. Most importantly to me, in the case of non-trivial examples, I hope to identify what the relevant technical concepts are and how they work up to the final result of each example.

Other material related to this book: Throughout this book you will see file sizes specified with an assortment of units.

For example: 42 k B, 42 Mb, 42 Gi B, 42 G, 42 Gi B.

Without an explanation this may seem confusing, random, and inconsistent.

However, there is a method to this madness: If you find a typographical or any other error in this book, or if you have thought of a way to make this book better, I would love to hear from you!

Please submit a report in Git Hub: https://github.com/tbielawa/Virtual-Disk-Guide/issues If you have a suggestion for improving the book, try to be as specific as possible when describing it.

If you have found an error, please include the section number and some of the surrounding text so I can find it easily.

I also recommend you review the suggestions in Chapter7, Troubleshooting/FAQs.

If you're submitting an error with an example, please try and include as much relevant information about your setup as possible.

This includes (but is not limited to): your operating system and version, the version of the software the example happens with, if you are running the command as the root user or not, and the exact commands to run to reproduce the error.

In this section we're just going to cover things you'll find yourself needing to do from time to time. It's assumed that you're comfortable with the concepts already and don't need everything explained.
