FUSE

This page describes how to setup fuse inside VPS

Introduction

FUSE is a filesystem in which data and metadata are provided by an ordinary userspace process. The filesystem can be accessed normally through the kernel interface.

Preparations

To use FUSE you need the following:

1. OpenVZ kernel version 028test005 or higher
2. Fuse lib
3. Any FUSE-based filesystem

In the examples below sshfs is used.

Setup

Kernel

Download appropriate kernel from openvz.org or compile kernel with CONFIG_FUSE_FS option set

Libfuse

Compile libfuse in VPS witout kernel module

# vzctl enter 100
# tar xzf fuse-2.6.0.tar.gz
# cd fuse-2.6.0
# ./configure --disable-kernel-module
...
# make
...
# make install

Filesystem

Download and compile filesystem.

# vzctl enter 100
# tar xzf sshfs-fuse-1.7.tar.gz
# cd sshfs-fuse-1.7
# ./configure
...
# make
...
# make install

VPS tuning

You need to make a characted device named /dev/fuse and grant your VPS permissions to it

# vzctl set 100 --devices c:10:229:rw --save
...
# vzctl exec 100 mknod /dev/fuse c 10 229
...

Mounting filesystem

After this you may try to mount FUSE in VPS

# vzctl enter 100
# sshfs root@foo.org:/root /mnt/foo.org.root

Using fusectl filesystem

Fusectl is a helper filesystem for FUSE. You may mount it in VPS as well

# vzctl enter 100
# mount -t fusectl none /fuse_ctl
