Ext4fuse: mount ext4 partition on mac or any other fuse platform I've been working with this for some time, and it has reached a point where I no longer feel embarrassed to show the code:). I wanted to be able to read ext4 partitions on my mac, and I was curious about ext4 so this is the result. When layered on top of Ext4 compared to native Ext4. We used a wide variety of micro- and macro-workloads, and different hardware using basic and optimized conﬁg-urations of FUSE. We found that depending on the work-load and hardware, FUSE can perform as well as Ext4, but in the worst cases can be 3 slower.

From Wikipedia:

In computing, a file system or filesystem (often abbreviated to fs), controls how data is stored and retrieved. Without a file system, information placed in a storage medium would be one large body of data with no way to tell where one piece of information stops and the next begins. A file system separates the data into pieces and gives each piece a name. Each group of data is called a 'file'.

There are many different kinds of file systems. Each one has different structure and logic, properties of speed, flexibility, security, size and more.

Files and directories themselves are placed on top of the file system, therefore it is common to refer to the file/directory structure itself as 'file system'. On GNU/Linux, the Filesystem Hierarchy Standard defines the naming scheme and hierarchy between files and directories themselves.

Fuse Vs Ext4

File systems usually sit on top of hard disk partitions or LVM volumes. In Debian, ext4 is the default file system for new installations.

GNU/Linux can be installed on any filesystem that supports some special constructs (file permissions, symbolic links and device files).

Many file systems are journaling, meaning they are able to prevent data loss on system crashes or power failures.

Mounting a filesystem

In GNU/Linux the contents of a filesystem can be made available under a directory, by mounting the filesystem over the directory. Here are some ways to mount a filesystem:

The mount command. For example mount /dev/sdd1 /mn/ would make contents of the first partition of the /dev/sdd disk device, available in the /mnt/ directory.
Editing the fstab file

Filesystems available in Debian Linux kernel

Note0: Debian HURD and Debian kFreeBSD have other file systems.

Note1: the Features list are incomplete at this time.

Note2: This table is uptodate as of 2.6.28 kernel.
