In July I was commissioned to write an article for LinuxWorld called “Emerging Linux Filesystems [1]” which they published in early September in three parts [2]. 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 [1] 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 [3] for commissioning (and paying for) the article and to Dragan Dimitrovici of Xenon Systems [4] for the loan of the test system [5]!
