DESCRIPTION
newfs -F vxfs
builds a VxFS file system by invoking
mkfs.
special
specifies a character (or raw) file
(for example,
/dev/rdsk/c0t6d0).
Options
newfs
recognizes the following options:
- -B
Reserve space for boot programs past the end of the
file system. If the file
/usr/lib/uxbootlf
is present on the system, sufficient space to accommodate
that file is reserved; otherwise 691 kilobytes are reserved.
This option decreases the size of the file system being
created. This option cannot be used if the file-system size is
also specified using
-s
(see
mkfs_vxfs
options below).
- -F vxfs
Specify the file-system type
vxfs.
- -O disk_type
Use disk parameters from the
disk_type
named in
/etc/disktab.
This option is provided for backward compatibility with
previous HP-UX releases. Any parameters specified on the
command line will the corresponding values in
/etc/disktab.
Any values not specified in the command line and not shown in
/etc/disktab
are defaulted.
- -R swap
Reserve
swap
megabytes of swap space past the end of the file system.
This option decreases the size of the file system to
be created by the specified number of megabytes.
-R
cannot
be used if the file-system size is also specified using
-s
(see
mkfs_vxfs
options below).
- -v
Specify verbose mode.
newfs
prints out its actions, including the parameters passed
to
mkfs.
- -V
Echo the completed command line, but do not execute the command.
If not valid,
-V
prints an error message.
The command line is generated by incorporating the
user-specified options and other information derived from
/etc/fstab.
This option allows the user to verify the command line.
NOTE:
You can specify the
-R
and
-B
options in the same command line.
In that case, both the requested swap space and the space needed for
boot programs are reserved.
These options are used when the file system size is defaulted
to the size of the entire disk.
mkfs_vxfs Options
The following additional command-line options can be used
to override default parameters passed to
mkfs_vxfs:
- -b block_size
File system block size in bytes. The default value is
1024 bytes for systems smaller than two terabytes.
For Version 5 disk layout file systems larger than two terabytes,
the maximum file system size is dependent on the block size.
A four terabyte file system requires a 1K block size,
An eight terabyte file system requires a 2K block size,
a 16 TB file system requires a 4K block size,
and a 32 TB file system requires an 8K block size.
- -o largefiles | nolargefiles
Valid only for the Version 4 and 5 disk layouts.
This option controls the largefiles flag for the file system.
If
largefiles
is specified, the bit is set
and files two gigabytes or larger can be created.
If
nolargefiles
is specified,
the bit is cleared and files created on the files system
are limited to less than two gigabytes.
The default is
nolargefiles.
See
mkfs_vxfs(1M),
mount_vxfs(1M)
and
fsadm_vxfs(1M).
- -s size
File system size in
DEV_BSIZE
blocks (defined in
<sys/param.h>).
The default value is the size of the entire disk or disk
section, minus any swap or boot space requested.
The
size
specifies the number of sectors in the file system.
By default, size is specified in units of
DEV_BSIZE
sectors. However, you can append
a suffix to
size
to indicate another unit of measure.
Append
k
or
K
to indicate that the value is in kilobytes,
m
or
M
to indicate megabytes, or
g
or
G
to indicate gigabytes.
Operands
newfs
recognizes the following operand:
- special
A character (raw) file.
EXAMPLES
To create a VxFS file system on
/dev/rdsk/c1t5d0
and reserve 40 megabytes of swap space.
newfs -F vxfs -R40 /dev/rdsk/c1t5d0
FILES
- /etc/disktab
Disk description file.
- /etc/fstab
Static information about the file systems.
