UFS
UFS stands for
UNIX file system, which was originally developed from the first versions of
UNIX at
AT&T. The file system reached its current status in the 4.x BSD distributions. It it currently used in
FreeBSD,
NetBSD as well as
OpenBSD and the
Solaris Operating Environment.
Linux support is available, but is not standard.
FreeBSD versions 5.0 introduced UFS2, which allows soft updates, a more efficient method of writing file system meta data, as well as support for volumes over 1TB in size.
