.Dt FSINFO 8
.Os BSD 4.4
.Sh NAME
.Nm ffsinfo
.Nd dump all meta information of an existing ufs file system
.Sh SYNOPSIS
.Nm ffsinfo
.Op Fl L
.Op Fl g Ar cylinder group
.Op Fl i Ar inode
.Op Fl l Ar level
.Op Fl o Ar outfile
.Ar < special | file >
.Sh DESCRIPTION
.Nm Ffsinfo
extends the
.Xr dumpfs 8
program.
.Pp
The output is generated into the file
.Nm outfile .
Also expect the output file to be rather large. Up to 2 percent of the size
of the specified filesystem is not uncommon.
.Nm Ffsinfo
has some options to allow the defaults to be overridden.
.\".Pp
.Bl -tag -width indent
.It Fl L
Specifying this options skips the tests of the disklabel. This is automatically
done, if the specified filename to dump is a plain file.
.It Fl g Ar cylinder group
This restrictes the dump to infomation about this cylinder group only. Here
0 means the first cylinder group and -1 the last one.
.It Fl i Ar inode
This restrictes the dump to infomation about this particular inode only. Here
the minimum acceptable inode is 2. If this option is omitted but a cylinder
group is defined then only inodes within that cylinder group are dumped.
.It Fl l Ar level
The level of detail which will be dumped. This value defaults
to 255 and is the bitwise and of the following table:
.Bd -literal -offset left
0x001 - initial superblock
0x002 - superblock copys in each cylindergroup
0x004 - cylinder group summary in initial cylinder group
0x008 - cylinder group information
0x010 - inode allocation bitmap
0x020 - fragment allocation bitmap
0x040 - cluster maps and summary
0x080 - rotational layout tables
0x100 - inode information
0x200 - indirect block dump
.Ed
.It Fl o Ar outfile
This allows to change the output filename where the dump is written to. The
current default is
.Nm /var/tmp/ffsinfo .
.El
.Sh EXAMPLES
.Pp
.Dl ffsinfo -l 1023 /dev/vinum/testvol
.Pp
will dump /dev/vinum/testvol with all available information.
.Sh BUGS
Currently
.Nm
can only dump unmounted file systems. Do not try dumping a mounted file system,
your system may panic and you will not be able to use the file system any
longer.
.Pp
Also snapshots are handled like plain files. They should get a their own
level to provide for independent control of the amount of what gets dumped. It
probably also makes sense to some extend to dump the snapshot as a filesystem.

.Sh NAME
.Nm growfs
.Nd grow size of an existing ufs file system
.Sh SYNOPSIS
.Nm growfs
.Op Fl Ny
.Op Fl s Ar size
.Ar special
.Sh DESCRIPTION
.Nm Growfs
extends the
.Xr newfs 8
program.
Before running
.Nm
the disk must be labeled to a bigger size using
.Xr disklabel 8 .
If you are using volumes you must grow them using
.Xr vinum 8 .
.Nm Growfs
extends the size of the file system on the specified special file.
Currently
.Nm
can only grow unmounted file systems. Do not try growing an mounted file system,
your system may panic and you will not be able to use the file system any longer.
Most of the options you have used with
.Xr newfs 8
once can not be changed. In fact you can only increase the size of the file
system. Use
.Xr tunefs 8
for other changes.
Typically the defaults are reasonable, however
.Nm
has some options to allow the defaults to be overridden.
.\".Pp
.Bl -tag -width indent
.It Fl N
Cause the new file system parameters to be printed out
without realy growing the file system.
.It Fl y
.Dq Expert mode
Normally
.Nm
will ask you, if you took a backup of your data before und will do some tests
if
.Ar special
is currently mounted or if there are any active snapshots on the filesystem
specified. This will be supressed. So use this option with care!
.It Fl s Ar size
The size of the file system after growing in sectors. This value defaults
to the size of the raw partition specified in
.Ar special
(in other words,
.Nm
will grow the file system to the size of the entire partition).
.El
.Sh EXAMPLES
.Pp
.Dl growfs -s 4194304 /dev/vinum/testvol
.Pp
will grow /dev/vinum/testvol up to 2GB if there is enough space in
/dev/vinum/testvol .
.Sh BUGS
In some cases on
.Bx Free
3.x it is possible, that
.Nm
did not recognize exactly, if the file system is mounted or not and
exits with an error message, then use
.Nm
-y if you are sure, that the file system is not mounted.
It is also recommended to always use
.Nm fsck
after growing just to be on the safe side.
.Pp
Pay attention, as in certain cases we have to change the location of an file
system internal structure which had never been moved before. Almost everything
works perfect with this relocated structure except the
.Nm fsck(8)
utility. There is a patch available for
.Nm fsck(8) .
For growing above certain limits it is essential to have some free blocks
available in the first cylinder group. To avoid the relocation of that
structure it is currently recommended to use
.Nm ffsinfo -c 0
on the first cylinder group and check that
.Nm nbfree
in the CYLINDER SUMMARY (internal cs) of the CYLINDER GROUP
.Nm cgr0
has enough blocks. As a rule of thumb for default filesystem parameters a block
is needed for every 2 GB of total filesystem size.
