PrinterFS

Distributed filesystem.

Goals

Spread non-replicated files over many, small-disk, cheap boxes
Files should be owned by a single node, so contention should be less of a problem
Simple to configure, setup, keep running. As few bells and whistles as possible.
DHT
As safe as possible, make trade-offs for safety over latency when the question arises.

In-memory LRU cache for files and metadata on every node. Should be configurable.
Simple rehashing/auto-discovery. If a new node comes online, make sure files that are now in it's keyspace are moved to it from the nodes previous.
Compression for over-the-wire transfers (LZ4 is pretty easy)

Make sure you have your kernel headers available. On Ubuntu, you can do:

sudo apt-get install linux-headers-$(uname -r)

Then you should just be able to:

make
sudo insmod PrinterFS.ko

sudo rmmod PrinterFS
