btfs

A basic simple in-memory file-system using b-trees.

FUSE Example

Set up FUSE: ``` $ apt-get install fuse libfuse-dev

Make sure fuse.conf has allowroot and userallow_other set:

$ cat /etc/fuse.conf allowroot userallow_other ```

Test the system: $ RUST_LOG=trace cargo run --bin fuse /tmp/test

Unmount: $ umount /tmp/test

Testing with filebench

Installing filebench:

$ git clone https://github.com/filebench/filebench.git $ libtoolize $ aclocal $ autoheader $ automake --add-missing $ autoconf $ ./configure $ make

Running a benchmark: ``` $ mkdir -p /tmp/fbtest $ cargo run --release --bin fuse -- /tmp/fbtest/ &

$ echo 0 > /proc/sys/kernel/randomizevaspace $ ./filebench -f randomrw.f

$ umount /tmp/fbtest ```
