PUFS - Peer Union File System - is a poor man's na???ve distributed file system built on top of FUSE, hence running totally in user space.<br /><br />The project is distributed under the GPL license.<br /><br />PUFS' philosophy is somewhat in line with a network grid paradigm in the form of a file system: its contents consists in a unified view of the directories exported by each peer and can become larger or smaller as these peers join or leave this "union".<br /><br />It is designed to work best on LANs where multicast is readily available, allowing seamless peer auto-discovery and notification. It can also be used in unicast mode, but it this case all the contributing peers must be enumerated in advance.<br /><br />The peers constitute a topological mesh where any peer is virtually connected to every other one, so that the unified file hierarchy will be the same all around, whichever node a snapshot is taken.<br /><br />Since there's no central authority enforcing membership or maintaining connectivity status, peers are actually loosely bound to the "union" and can leave or join any time.<br /><br />Changes in the file system, both data and metadata are reflected on a best effort basis. In particular, the most recently accessed metadata is typically cached and is considered valid throughout a configurable period of time, after which it is refreshed.<br /><br />One the other hand, a failure or a downtime in one node will be reflected in PUFS by the disappearance of the segment or top directory exported by that very peer.<br /><br />PUFS is an almost POSIX compliant file system with the current exception of of both symbolic and hard links which are lacking.<br /><br />File locking, both mandatory and advisory, is also missing due to a limitation in FUSE which doesn't dispatch fcntl(2) calls to the applications.<br /><br />Usage scenarios<br /><br />PUFS setting up is simple, just throw in a bunch of cooperating peers and you can have instantly a distributed file system up and running. This simplicity comes, however, with a price: despite a limited support for replication, PU
