These two videos show how to set up a software RAID1 under FreeNAS.
If you’re wondering what RAID1 means, RAID1 uses mirroring to write data to for instance two drives. This means that when you write a file or save a video, the file is written to two disks. If one of the disks fails, you simply replace it and rebuild the mirror, i.e. one disk is an exact copy of they other. The tradeoff with this setup is cost. With RAID1, you purchase double the amount of storage space that your data requires.
The presentations from the recent MeetBSD 2010 (Cracow, Poland) conference are now available on the BSD Conferences Youtube Chanel. The following videos are all in HD quality and most are in English, though a few are in Polish.
Abstract: The sysinstall tool has been the default system installer for FreeBSD for more than a decade now. While is it has proven itself to be reliable and resilient over the years, it doesn’t support many of the new features that FreeBSD offers, as well as being un-intuitive for desktop users, who expect an easy to use graphical front-end to perform their installation. To solve these two problems the “pc-sysinstall” backend was created and now is in usage for PC-BSD 8.0. This new installer backend provides much of the same functionality as sysinstall, while offering many new features such as support for ZFS, Encryption, mirroring, scriptable installs and the ability to work with different front-ends, such as a QT based GUI. The backend also supports installing regular FreeBSD, which allows server administrators to quickly perform an installation using the new disk features it offers.
The presentation at AsiaBSDCon 2009 is focused on explaining theoretical approaches and pratical aspect of the locking support in the FreeBSD kernel. The locking KPI as well as underlying mechanisms and interactions with the scheduler will be analized and discussed deeply. Typical locking strategies and some edge cases will also be shown along with a detailed explanation about how to debug locking problems (deadlocks and races primirally).
At The Aerospace Corporation, we run a large FreeBSD based computing cluster to support engineering applications. These applications come in all shapes, sizes, and qualities of implementation. To support them and our diverse userbase we have been searching for ways to isolate jobs from one another in ways that are more effective than Unix time sharing and more fine grained than allocating whole nodes to jobs. In this paper we discuss the problem space and our efforts so far. These efforts include implementation of partial file systems virtualization and CPU isolation using CPU sets.
In this paper we describe usage of FreeBSD operating system for IPv6 Multicast routing platform in SOI-Asia Project. SOI-Asia project is platform to deliver realtime lecture via UniDirectional Link of satellite to several countries in Asia. Because of limited bandwidth in satellite, we use IPv6 multicast to deliver material of lecture and realtime video and audio lecture. We also describe human resources development of operational aspect of the project in several countries in Asia.
FreeBSD has a reputation for its rock-solid reliability, and top-notch performance in the server world, but is noticeably absent when it comes to the vast market of desktop computing.
Why is this? FreeBSD offers many, if not almost all of the same open-source packages and software that can be found in the more popular Linux desktop distributions, yet even with the speed and reliability FreeBSD offers, a relative few number of users are deploying it on their desktops. In this presentation we will take a look at some of the reasons why FreeBSD has not been as widely adopted in the desktop market as it has on the server side. Several of the desktop weaknesses of FreeBSD will be shown, along with how we are trying to fix these short-comings through a desktopcentric version of FreeBSD, known as PCBSD. We will also take a look at the package management system employed by all open-source operating systems alike, and some of the pitfalls it brings, which may hinder widespread desktop adoption.
