The State of ZFS On Linux

Linux Slashdot - Thu, 11/09/2014 - 15:55
An anonymous reader writes: Richard Yao, one of the most prolific contributors to the ZFSOnLinux project, has put up a post explaining why he thinks the filesystem is definitely production-ready. He says, "ZFS provides strong guarantees for the integrity of [data] from the moment that fsync() returns on a file, an operation on a synchronous file handle is returned or dirty writeback occurs (by default every 5 seconds). These guarantees are enabled by ZFS' disk format, which places all data into a Merkle tree that stores 256-bit checksums and is changed atomically via a two-stage transaction commit.. ... Sharing a common code base with other Open ZFS platforms has given ZFS on Linux the opportunity to rapidly implement features available on other Open ZFS platforms. At present, Illumos is the reference platform in the Open ZFS community and despite its ZFS driver having hundreds of features, ZoL is only behind on about 18 of them."

Learning About Enea's Real Time Linux Embedded OS (Video)

Linux Slashdot - Wed, 10/09/2014 - 22:02
Jon Aldama is the Product Marketing Manager for Enea A.B., but he prides himself on being a developer first and a marketer second -- a point he stresses early in today's video. Enea is behind Operating System Embedded, whose Wikipedia page, some say, "appears to be written like an advertisement," which an unkind person could also say about the Enea A.B. Wikipedia page. In any case, Enea works with the Linux Foundation's Yocto Project workgroup, whose main webpage says, "It's not an embedded Linux distribution – it creates a custom one for you." This is all open source, which Jon says is a big corporate principle at Enea -- and he should know, since his previous job was as an Open Source Compliance Officer and Software Analyst at Ericsson.

MesosCon Highlights: Apache Mesos 0.20 and Docker Support

Linux.com - Tue, 09/09/2014 - 00:27

Isabel Jimenez will graduate from her master in Computer Science this month. She spent three months contributing to Apache Mesos with the Twitter team thanks to Gnome’s Outreach Program for Women.

Apache Mesos had its first annual conference in collaboration with LinuxCon North America this year. I attended the conferences because its one of the major open source events of the year and also because I volunteered to be part of MesosCon program committee.

MesosCon started with a keynote from Benjamin Hindman, one of the creators of the project and Mesos team lead. One of the major news items in this keynote was the release of Apache Mesos version 0.20 later that day. This release answered a popular request from Mesos users: Docker integration.

Although it was already possible to launch Docker containers with Mesos, thanks to the external containerizer mechanism, Docker has become a first-class citizen. With Mesos 0.20 it is now possible to use Docker containers without any external installation.

The history of Mesos with containers goes back to the start of the project, in 2011. The Mesos default containerizer used LXC. Later for better integration Mesos decided to use cgroups directly.

With Docker’s popularity growth, Mesos started supporting Docker with some work like mesos-docker, an executor, and later with Deimos, an external containerizer.

But to fully enjoy all of Docker’s features, this year it became fully integrated into Mesos. This means that a specific containerizer was created for Docker inside Mesos.

A new component, ContainerInfo was added as the base protobuf message along with a DockerInfo that helps to lend parameters to Docker container specifics. The ContainerInfo base was added to TaskInfo and ExecutorInfo also to allow users to launch Docker as a task or an executor.

What the Docker containerizer does is simply translate Task/Executor Launch and Destroy calls to the Docker CLI commands.

In my opinion, this announcement is a immense step towards what could be the future of Docker containers orchestration. Other new tools are coming to the surface to answer this huge demand but they are no more than a Docker API smart overlay and still lack lots of improvements.

 

 

Supporting Docker Integration

One of the speakers at MesosCon was Victor Vieux, a Docker core maintainer, who talked about how easy it was to use this new integration to build new Mesos frameworks. He demonstrated Volt,  a framework I had the chance to work on, that serves as perfect proof-of-concept for Mesos Docker support and its easy and quick application.

Although not every Docker feature is supported yet in Mesos, Volt allows a user to launch tasks inside Docker containers, letting the user benefit at the same time from Mesos resource management.

The Marathon Mesos framework, by mesosphere was also quickly updated to support this new Docker integration.

The community had a quick positive reaction to all these changes and in my opinion, is eager to see the integration fully developed. Especially about letting Docker containers be linked and communicate with each other.

The event was also a great chance to talk with all Mesos users and developers. As part of the organizing committee I had the occasion to participate in the speaker dinner where I witnessed the great energy behind different Mesos use cases.

The hackathon day was a great opportunity to hack on the Mesos ecosystem and implement the newly announced features, for example JenkinsOnMesos, which added Docker support during the hackathon.

It was also an opportunity for me to continue some work on Volt and get firsthand feedback on it.

Of course MesosCon was about much more than this fantastic news. All the talks were rewarding, the open-mindness  of the Apache Mesos community lead to very interesting talks on different cluster management approaches and how to make Mesos better. Benjamin Hindman let us know that 1.0 release was as near as some API upgrades and we are all looking forward to MesosCon 2015!
