In my first entry in this blog, when I set up the hard disk partitions it was ready to install Windows. However, since then I had not returned to deal with this issue and now is the time to take it up.
Since Windows 8, the Windows installer is able to install Windows on GPT partitioned disks, as long as the computer supports the UEFI mode.
In this post I intend to show a method to work around this limitation of Windows installer. I'll install Windows 10 on a computer with a traditional BIOS and the hard disk partitions with GPT style.
The Devil is in the Detail
As sysadmin I know that the key to success in my profession, or failure, is in the care of the "little things" that are often overlooked and usually occur at the worst time; because Devil is in Details.

Cloning FreeBSD Jails with ZFS as a method for provisioning Oracle 11g R2
A requirement more and more pressing in the current data centers is the ability to deploy applications and services quickly, almost immediately.
It is becoming increasingly frequent that the system administrators and DBAs maintain different versions of the same service or application to be used as production environment, testing, development, reporting.
In this post I will show, as the combination of ZFS and FreeBSD Jails can simplify these tasks to the point that are almost trivial.

Install Oracle 11g Release 2 on FreeBSD 9
We Continue providing functionality to our Jail Debian GNU / Linux just installed. For it I decided to install Oracle 11gR2 for Linux, because it is one of the most demanding software packages that can be found, I think it's a good way to explore the limits of the proposed solution.
Another motivation is the fact that in the FreeBSD HandBook the chapter dedicated to installing Oracle is referred to version Oracle 8.0.5, which is quite old, this circumstance stimulated my curiosity.
For failing be certified by Oracle, this platform is not suitable for a production environment, which does not diminish the utility as a test environment and even a development environment for small projects, depends on the risk you want to take.
The advantages of using FreeBSD as an infrastructure for virtualized environments are:

The advantages of using FreeBSD as an infrastructure for virtualized environments are:
- ZFS File System.
- Virtual network stack.
- Network security with pf.
- Dtrace performance analysis.
- Debian GNU is one of the most reliable Linux distribution and have a very predictable release cycle.
- Using a complete distribution saves us a lot of work when you install Oracle.
- Provide updated technical documentation.

Install Debian GNU/Linux on a FreeBSD Jail with ZFS
Continuing with the process of configuring a newly installed FreeBSD system to get a production environment with hosted services in Jails.
We will continue working with Debian and Linux-based distributions that provide the right Userland to meet the goal, not fully achieved, of executing Linux binaries on FreeBSD Jail.

Install Debian GNU/kFreeBSD on a FreeBSD Jail with ZFS
Once we have installed and updated a FreeBSD 9 system, the next step is to provide it with apps to make it a useful system.
In recent years, I have been working on Solaris 10 systems, where services had in production were encapsulated in Solaris Containers. Given my recent interest in FreeBSD seems natural to attempt to play a similar execution environment, which gave me such good results in the past.
Moreover, it seems interesting the possibility to include the ability to run Linux applications and having a jail specifically intended for that purpose.
In this case, instead of installing a Jail with the FreeBSD native userland, we will install Debian GNU/kFreeBSD that provides an alternative userland for FreeBSD 9.

Updating FreeBSD 9 with freebsd-update and beadm
In my previous post I described how Install FreeBSD 9 with root on ZFS with support for beadm, now my purpose is to show the advantages of this configuration to deal with tasks so committed like operating system updates.

Install FreeBSD 9 with root on ZFS optimized for 4K sectors and support for beadm
In the last 6 years I have worked with Solaris 10 SPARC systems - M3000 , M4000 , V1280 - where I used ZFS as filesystem.
For a while I looked for solutions on x64 architecture servers similar in performance and features of these systems.
Of course the obvious answer is to opt for environments under Solaris 11 for x64; technologically is a good solution -not perfect- but given the apparent corporate culture change that has occurred after the acquisition of Sun by Oracle, never hurts to evaluate alternatives
Btrfs in Linux seems an option to keep in mind, however it suffers , in my opinion of a certain technological immaturity that makes not advisable its use, at the moment, for deployment in production environments.
The solution presented in this post is today, I think of the most interesting, because combines an open source OS, with an undeniable technological maturity and probably the best filesystem today; ZFS.
