ZFS is a combined file system and logical volume manager originally designed by Sun Microsystems. It was ported to FreeBSD and has been part of the operating system since FreeBSD 7.0. FreeBSD 6.x use UFS.

Hi all
I plan to install Solaris 10U6 on some SPARC server using ZFS as root pool, whereas I would like to keep the current setup done by VxVM:
- 2 internal disks: c0t0d0 and c0t1d0
- bootable root-volume (mirrored, both disks)
- 1 non-mirrored swap slice
- 1 non-mirrored slices for Live... (1 Reply)

Other than export/import, is there a cleaner way to rename a pool without unmounting de FS?
Something like, say "zpool rename a b"?
Thanks. (2 Replies)

libufs
LIBUFS(3) BSD Library Functions Manual LIBUFS(3)
NAME
libufs -- operate on UFS file systems from userland
LIBRARY
UFS File System Access Library (libufs, -lufs)
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
#include <ufs/ufs/ufsmount.h>
#include <ufs/ufs/dinode.h>
#include <ufs/ffs/fs.h>
#include <libufs.h>
DESCRIPTION
The libufs library and the functions it provides are used for implementing utilities which need to access a UFS file system at a low level
from userland. Facilities provided are used to implement utilities such as newfs(8) and dumpfs(8). The libufs library is designed to be
simple, and to provide functions that are traditionally useful to have.
A disk is represented as the type struct uufsd as defined in <libufs.h>. The structure is filled out, operations are performed, and the disk
is closed.
ERRORS
Functions provided by libufs return -1 in every functional error situation. They also set the d_error field of struct uufsd to a string
describing the error.

ufs_disk_fillout_blank(3), ufs_disk_write(3), ffs(7)
HISTORY
The libufs(3) library first appeared in FreeBSD 5.0.
