EXT2FS(4)		     Kernel Interfaces Manual		       EXT2FS(4)

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 re-
     quired by ext3 and ext4 file systems.  Support for Extended  Attributes  in
     ext4  is  experimental.   Journalling and encryption are currently not sup-
     ported.

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 modified,
     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 implementation.
     Zheng Liu and Fedor Uporov implemented the read and write	support  respec-
     tively  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 <ro-
     drigc@FreeBSD.org>.

FreeBSD ports 15.1		December 30, 2018		       EXT2FS(4)
