3-Way Disk Mirrors With ZFS On Linux

ZFS is a member of the newer generation of filesystems that include advanced features beyond simple file storage. Its capabilities are quite extensive covering a wide range of pain points hit with previous filesystems. The Wikipedia page details them all nicely but for the purpose of this post we will be focusing on its ability to create N-Way sets of disk mirrors.

Traditionally mirrored disk sets in Linux and other operating systems have been limited to two devices (note: devices in this context could be disks, partitions or even other raid groups, such is the case in raid 10 setups). While mirroring has the benefit over other raid levels in that each mirrored device contains a complete copy of the data, the two device limit became inadequate as disk sizes ballooned. In the age of multi-TB drives, simply rebuilding a degraded mirrored array could actually cause the surviving device to fail, eliminating the very redundancy one was expecting.

ZFS addresses this particular problem in several ways through data checksums, self-healing and smart resilveringinstead of blindly rebuilding full array members even if only 1% of disk space is being used.

There was something about Cheryl Fillekes that Google really liked. Over a seven-year period, Fillekes, who specializes in Unix and Linux system programming, was contacted by Google recruiters four different times for jobs. In each case, she did well enough in the phone interviews to get an invitation for an in-person interview.

Despite all these interviews, Fillekes never got a job offer, and Google is now getting an age discrimination lawsuit.

Fillekes joined a lawsuit filed in April by Robert Heath, who was 60 in 2011 when he applied for a job at Google. The age discrimination complaint was amended recently to include Fillekes.

Startup Launches Big Data-as-a-Service

For many enterprises, big data is hard and slow. Procurement and deployment of data infrastructure can be both expensive and difficult to scale at the pace that data volumes can grow. A startup founded by former Netezza executives says that the answer to these data engineering woes is the cloud.

The startup, Cazena, came out of stealth today after two years of development with an enterprise big data-as-a-service offering intended to simplify and automate securely moving and optimizing big data processing in the cloud. It’s a managed service platform that founder and CEO Prat Moghe — who served as senior vice president of strategy, products and marketing at Netezza — says addresses the security and complexity challenges that have kept many enterprises from migrating their big data workloads to the cloud.

According to Canonical, a number of security issues have been found within MySQL, which means that it’s time to integrate yet another version from upstream sources. Nothing out of the ordinary has jumped out, but it’s a good idea to upgrade nonetheless.

Carrying out common daily tasks such as burning a DVD through the comfort of a user-friendly graphical interface is, of course, a good thing, but unfortunately things don’t always work as expected. When this is the case, Linux users can revert to the good old terminal to get things done no matter what. On this quick tutorial, we will see how Linux users can utilize the terminal to burn audio CDs, data DVDs or ISO images on a disk.
