Fuse-ext2 is a EXT2/EXT3/EXT4 filesystem support for fuse and is built to work with osxfuse.

Dependencies

Fuse-ext2 requires at least Fuse version 2.6.0 for Linux.
Fuse-ext2 requires at least Fuse for macOS version 2.7.5 or greater.

Linux: Fuse
macOS: Fuse for macOS

Alternate Install method of Fuse for macOS

Fuse for macOS can be installed via homebrew if Homebrew-Cask has been tapped.

To tap Homebrew-Cask

brew tap homebrew/cask

To verify the the above tap is apart of brew

brew tap

Look for homebrew/cask in the output.

To install Fuse for macOS using brew

brew cask install osxfuse

Build

Linux

Build from source depends on:

m4
autoconf
automake
libtool
libfuse-dev
e2fsprogs
comerr-dev
e2fslibs-dev

apt-get install m4 autoconf automake libtool
apt-get install libfuse-dev e2fsprogs comerr-dev e2fslibs-dev
./autogen.sh
./configure
make
sudo make install

You can use checkinstall or some other equivalent tool to generate install package for your distribution.

FreeBSD

Install via pkg:

pkg install sysutils/fusefs-ext2

Build via ports:

cd /usr/ports/sysutils/fusefs-ext2
make install clean

macOS

Dependencies:

OSXfuse Building from source depends on:

m4
autoconf
automake
libtool
e2fsprogs
xcode-select

Copy and paste this into a file such as /tmp/ext4/script.sh. Remember to chmod +x script.sh. Run it from that directory - ./script.sh

Test

The e2fsprogs live in /opt/gnu/bin and /opt/gnu/sbin, fuse-ext2 is in /usr/local/bin

cd
dd if=/dev/zero of=/tmp/test-fs.ext4 bs=1024 count=102400  
/opt/gnu/sbin/mkfs.ext4 /tmp/test-fs.ext4
mkdir -p ~/mnt/fuse-ext2.test-fs.ext4
fuse-ext2  /tmp/fuse-ext2.test-fs.ext4 ~/mnt/fuse-ext2.test-fs.ext4 -o rw+,allow_other,uid=501,gid=20

Utilities such as **mkfs.ext{2,3,4} will be located within the **build/fuse-ext2.build/gnu/{bin,sbin} A prefix can be set / changed in the build script if a different path is desired to store the utilities.

To verify UID and GID of the user mounting the file system

id

To verify the file system has mounted properly

mount

Usage

See Man page for options.

Usage:    fuse-ext2 <device|image_file> <mount_point> [-o option[,...]]

Options:  ro, rw+, force, allow_other
          Please see details in the manual.

Example:  fuse-ext2 /dev/sda1 /mnt/sda1

Bugs

Multithread support is broken for now, so forcing fuse to work single thread.
there are no known bugs for read-only mode, read only mode should be ok for every one.
although, write support is available please do not mount your filesystems with write support unless you do not have anything to loose.

Please send output the output of below command while reporting bugs as GitHub Issue. Before submitting a bug report, please look at the existing issues first.

/usr/local/bin/fuse-ext2 -v /dev/path /mnt/point -o debug

Important: Partition Labels

Please do not use comma , in partition labels.

Wrong: e2label /dev/disk0s3 "linux,ext3"

Correct: e2label /dev/disk0s3 "linux-ext3"
