+# Gvfs-fuse
+
+Gvfs-fuse is the Fuse client for Gravitino fileset. It allows users to mount
Gravitino filesets to their local file system via Fuse, enabling access to
Gravitino fileset files as if they were part of the local file system.
+
+## Features
+
+- Supports mounting S3 filesets
+- Supports basic file read and write operations
+- Supports directory operations
+- Allows file attribute manipulation
+
+
+## Environment setup and build instructions
+
+### Prerequisites
+
+You need to install the following software before you can build gvfs-fuse:
+
+- [fuse3 and
libfuse3-dev](https://www.kernel.org/doc/html/next/filesystems/fuse.html) for
Linux systems.
+- [macFUSE](https://macfuse.github.io) for macOS systems.
+- [Rust](https://www.rust-lang.org) environment for compiling.
+
+### Build process
+
+Navigate to the `client/filesystem-fuse` directory of the Gravitino project
and execute the following commands:
+
+```shell
+# Code verification
+make check
+
+# Code formatting
+make fmt
+
+# Building Gvfs-fuse
+make
+```
+
+After building, the `gvfs-fuse` executable will be located in the
`target/debug` directory.
+
+### Testing
+
+Run the following commands to execute tests:
+
+```
+# Run tests that do not depend on the S3 or Gravitino environment
+make test
+
+# Run tests that depend on the S3 environment
+make test-s3
+
+# Run integration tests that depend on the Gravitino fileset environment
+make test-fuse-it
+```
+
+## Usage Guide
+
+Navigate to the `clients/filesystem-fuse` directory, run the following
commands to view
+help information or to perform mounting operations:
+
+```shell
+# Display help information for gvfs-fuse
+target/debug/gvfs-fuse --help
+
+# Display help for the mount command
+target/debug/gvfs-fuse mount --help
+
+# Display help for the umount command
+target/debug/gvfs-fuse umount --help
+
+#create mount directory
+mkdir -p target/gvfs
+
+# Execute the mount command in the foreground
+# mount the fileset uri to the local directory target/gvfs. You need to start
the gravitino server and create the fileset first
+target/debug/gvfs-fuse mount target/gvfs gvfs://fileset/test/c1/s1/fileset1 -c
conf/gvfs_fuse.toml -f
+
+# Execute the mount command in the background
+# mount the fileset uri to the local directory target/gvfs
+target/debug/gvfs-fuse mount target/gvfs gvfs://fileset/test/c1/s1/fileset1 -c
conf/gvfs_fuse.toml
+
+# Execute the umount command
+# unmount the fileset from the local directory target/gvfs
+target/debug/gvfs-fuse umount target/gvfs
+```
+
+The `conf/gvfs_fuse.toml` file is a configuration file that contains the
following information:
+
+```toml
+# fuse settings
+[fuse]
+file_mask = 0o600
+dir_mask = 0o700
+fs_type = "memory"
+data_path = "target/gvfs-fuse"
+
+[fuse.properties]
+
+# filesystem settings
+[filesystem]
+block_size = 8192
+```
+
+The `gvfs mount` command starts a FUSE program with the given configuration,
using a `MemoryFilesystem` for testing.
+You can access the filesystem in the `target/gvfs` directory.
+
+More configration file examples can be found in the `tests/conf` directory.
