Fuse Ext2

Fuse-ext2 is an EXT2/EXT3/EXT4 filesystem 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 that the the above tap is a part of brew:

brew tap

Look for homebrew/cask in the output.

To install Fuse for macOS using brew:

brew cask install osxfuse

Building

Debian/Ubuntu:

Building from source depends on the following:

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

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

Fedora

$ sudo dnf install @development-tools m4 autoconf automake libtool e2fsprogs libcom_err-devel fuse-libs e2fsprogs-devel
# build part 
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

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

FreeBSD:

Install via pkg:

$ pkg install sysutils/fusefs-ext2

Building via ports:

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

macOS:

Dependencies:

OSXfuse

Building from source depends on the following:

• 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

#!/bin/sh
export PATH=/opt/gnu/bin:$PATH
export PKG_CONFIG_PATH=/opt/gnu/lib/pkgconfig:/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

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 -o rw+,allow_other,uid=501,gid=20

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

id

To verify the file system has mounted properly:

mount

Usage

See the 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 fuse operates in a single thread.
• There are no known bugs for read-only mode, read only mode should be ok for everyone.
• Even though write support is available, please do not mount your filesystems with write support unless you have nothing to lose.

Please send the output of the command below when reporting bugs as a 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 commas , in partition labels.

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

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