EXT2FS(5)		    BSD	File Formats Manual		     EXT2FS(5)

NAME
     ext2fs -- ext2/ext3/ext4 file system

SYNOPSIS
     To	link into the kernel:

	   options EXT2FS

     To	load as	a kernel loadable module:

	   kldload ext2fs

DESCRIPTION
     The ext2fs	driver will permit the FreeBSD kernel to access	ext2 file sys-
     tems and its derivatives.	It currently implements	most of	the features
     required by ext3 and ext4 file systems.  Support for Extended Attributes
     in	ext4 is	experimental.  Journalling and encryption are currently	not
     supported.

EXAMPLES
     To	mount a	ext2fs volume located on /dev/ada1s1:

	   mount -t ext2fs /dev/ada1s1 /mnt

SEE ALSO
     nmount(2),	unmount(2), fstab(5), mount(8)

HISTORY
     The ext2fs	driver first appeared in FreeBSD 2.2.

AUTHORS
     The ext2fs	kernel implementation is derived from code written, or modi-
     fied, by Godmar Back using	the UFS	CSRG sources for CMU Mach.

     John Dyson	did the	initial	port to	FreeBSD.  Aditya Sarawgi merged	impor-
     tant parts	of the allocation code from a clean-room NetBSD	implementa-
     tion.  Zheng Liu and Fedor	Upurov implemented the read and	write support
     respectively for ext4 filesystems.	 The FreeBSD community has contributed
     a huge amount of modifications.

     The initial version of this manual	page was written by Craig Rodrigues
     <rodrigc@FreeBSD.org>.
