|

|
|
.Sh SYNOPSIS
|
|
.Nm

|
.Op Fl g Ar cylinder_group
|
|
.Op Fl i Ar inode
|
|
.Op Fl l Ar level
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility extends the
|
|
.Xr dumpfs 8
|
|
utility.
|
|
.Pp
|
|
The output is appended to the file
|
|
.Pa outfile .
|
|
Also expect the output file to be rather large.
|
|
Up to 2 percent of the size of the specified file system is not uncommon.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl g Ar cylinder_group
|
|
This restricts the dump to information about this cylinder group only.
|
|
Here
|
|
.Ar 0
|
|
means the first cylinder group and
|
|
.Ar -1
|
|
the last one.
|
|
.It Fl i Ar inode
|
|
This restricts the dump to information about this particular inode only.
|
|
Here the minimum acceptable inode is
|
|
.Ar 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
|
|
.Ar 255
|
|
and is the
|
|
.Dq bitwise or
|
|
of the following table:
|
|
.Pp

.Bl -hang -width indent -compact
|
|
.It Ar 0x001

|

inode information
|
|
.It Ar 0x200
|
|
indirect block dump
|
|
.El
|
|
.It Fl o Ar outfile
|
|
This sets the output filename where the dump is written to, and
|
|
must be specified.
|
|
If
|
|
.Fl
|
|
is provided, output will be sent to stdout.

.Sh BUGS
|
|
Snapshots are handled like plain files.
|
|
They should get 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
|
|
file system.
