The future is bright for Linux filesystems
In a recent article, Linux File Systems: Ready for the Future?, Henry Newman expands on what he feels are shortcomings in current GNU/Linux filesystems. Specifically, he believes current Linux filesystem technology cannot meet the demands that massive implementations of 100TB or larger require. He states he received some emotional responses trying to either refute his information or impugn his character, although those comments do not show on either of the article's pages. This prompted me to get the real scoop on how Linux filesystem technology is trying to keep pace with the ever-growing need for storage space.
Most of the native filesystems for Linux do have an issue with massive size. Regardless there are several new filesystems on the horizon that will move FOSS further into this massive size arena.
* ext4 - the newest ext filesystem version soon to be merged into the kernel.
* BTRFS - a new copy on write filesystem for Linux originally developed by Oracle.
* HAMMER - currently being developed solely for DragonFly BSD, but it is portable and open.
