nfs4fs

An fsspec filesystem (nfs4://) backed by the vectorized vnfs NFSv4.1 client.

The Rust extension (nfs4fs._native) links libntirpc statically, so import nfs4fs works without LD_LIBRARY_PATH.

Build

python3 -m venv .venv
.venv/bin/pip install maturin fsspec pytest
cd python
../.venv/bin/maturin develop

Use

import fsspec
import nfs4fs  # registers the "nfs4" protocol

fs = fsspec.filesystem("nfs4", host="127.0.0.1", root="git/some/tree")
fs.pipe({"nfs4:///a.txt": b"hello", "nfs4:///b.txt": b"world"})
print(fs.cat(["nfs4:///a.txt", "nfs4:///b.txt"]))

For tests without an NFS server, use backend="dummy" (a local-directory implementation of the same vectorized API):

fs = fsspec.filesystem("nfs4", backend="dummy", dummy_root="/tmp/scratch")
