In July I was commissioned to write an article for LinuxWorld called “Emerging Linux Filesystems” which they published in early September in three parts. Part of the deal was that there was a 90 day exclusivity period for them before I could republish it elsewhere, which has now lapsed.

So you can now read the article in its original (single page) form complete with inline images and graphs and covering Ext4, NILFS, btrfs, Reiser4, ChunkFS and ZFS under both FUSE on Linux and OpenSolaris. Enjoy!

My thanks to Don Marti of LinuxWorld for commissioning (and paying for) the article and to Dragan Dimitrovici of Xenon Systems for the loan of the test system!
