Fuse Ext2

Fuse-ext2 is a EXT2/EXT3/EXT4 Filesystem support for FUSE.


Fuse-ext2 requires at least Fuse version 2.6.0 for Linux. For Mac OS X latest version of OSXFuse 2.7.5.

  1. Linux: Fuse
  2. Mac OS: OSXFuse




# fuse
$ apt-get install libfuse

Build from source depends on:

  • m4
  • autoconf
  • automake
  • libtool
  • fuse-dev
  • e2fsprogs-dev
$ apt-get install m4 autoconf automake libtool
$ apt-get install libfuse-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.

Mac OS:


OSXfuse io no need to install with MacFuse compatibility.

The easiest way is using Homebrew:

$ brew install e2fsprogs m4 automake autoconf libtool pkg-config
$ git clone https://github.com/alperakcan/fuse-ext2.git
$ cd fuse-ext2
$ ./autogen.sh
$ ./configure \
    PKG_CONFIG_PATH="$(brew --prefix e2fsprogs)/lib/pkgconfig" \
    CFLAGS="-idirafter/$(brew --prefix e2fsprogs)/include -idirafter/usr/local/include/osxfuse" \
    LDFLAGS="-L$(brew --prefix e2fsprogs)/lib"
$ make
$ sudo make install         #<-- To install on the current system
$ make package              #<-- To create an install package in the current directory

See Man page for options.

Options:  ro, force, allow_others
          Please see details in the manual.

  • 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"
