Hi! > +Homepage: http://www.ioremap.net/projects/pohmelfs > + > +POHMELFS first began as a network filesystem with coherent local data and > +metadata caches but is now evolving into a parallel distributed filesystem. > + > +Main features of this FS include: > + * Locally coherent cache for data and metadata with (potentially) byte-range locks. > + Since all Linux filesystems lock the whole inode during writing, algorithm > + is very simple and does not use byte-ranges, although they are sent in > + locking messages. > + * Completely async processing of all events except creation of hard and symbolic > + links, and rename events. > + Object creation and data reading and writing are processed asynchronously. > + * Flexible object architecture optimized for network processing. > + Ability to create long paths to objects and remove arbitrarily huge > + directories with a single network command. > + (like removing the whole kernel tree via a single network > command). Hmm, so we'll need new unlink_recursively() syscall? > + * Very high performance. Do you have some nfs comparison?
