Highlights:

This month, we compare some leading Linux filesystems. We also show how to set up a storage cluster in the cloud, and we explore the userspace filesystem SSHFS.

SERVICE: Welcome

It is no secret that Ubuntu isn't the coolest, new-kid-on-the-block distro sensation anymore – actually that news is already a few years old. Still, Ubuntu has kept itself in the headlines with community dramas, desktop debates, and a crowd-funding effort to launch a mobile phone. The Ubuntu vision is so vast and enthralling that it is hard for the press – and the Ubuntu management – to let it go: a single unifying Linux popping up on phones, tablets, desktops, servers, and other devices that no one has even invented yet.

NEWS: This Month's DVD

The new Linux Mint 17 Cinnamon Edition long-term support release offers five years of upgrades, tweaks, improvements, and stability through 2019. Mint 17 has spiffed up its appearance and made changes so apps launch faster and use fewer resources.

NEWS: Choose a Filesystem

Comparing the ext3, ext4, XFS, and Btrfs filesystems

Every Linux computer needs a filesystem, and users often choose a filesystem by habit or by default. But, if you're seeking stability, versatility, or a small performance advantage, it pays to take a closer look.

: Storage Cluster

Ceph and OpenStack join forces

When building cloud environments, you need more than just a scalable infrastructure, you also need a high-performance storage component. We look at Ceph, a distributed object store and filesystem that pairs well in the cloud with OpenStack.

: SSHFS-MUX

Combining directories from multiple servers on a single mountpoint

With some simple tuning, SSHFS performance is comparable to NFS almost across the board. In an effort to get even more performance from SSHFS, we examine SSHFS-MUX, which allows you to combine directories from multiple servers into a single mountpoint.
