|
-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 and cannot be used if the file system size is
also specified using
-s (see
mkfs-options below).
This option cannot be specified if the file system is being created on
a volume set.
|
|
|
Note: You can specify the
-R and
-B options in the same command line.
In which 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.
|
|
-F vxfs |
Specifies the VxFS file system type.
|
|
-O disk_type |
| |
Uses the disk parameters from the
disk_type named in
/etc/disktab. This option
is provided for backward compatibility with
previous HP-UX releases. Parameters specified on the
command line override the corresponding values in
/etc/disktab. Values not specified in the command line and not shown in
/etc/disktab are defaulted.
|
|
-R swap |
Reserves
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_options below).
This option cannot be specified if the file system is being created on
a volume set.
|
|
-v |
Specifies verbose mode.
newfs prints out its actions, including the parameters passed
to
mkfs.
|
|
-V |
Validates the command line options, but performs no action.
If the options specified are valid,
-V echoes the complete command line.
If not valid,
-V prints an error message.
The command line is generated by incorporating
specified options and information derived from the
/etc/fstab file.
|
|
mkfs_options |
| |
The following command-line options
override the default parameters passed to
mkfs.
|
|
|
-b block_size | | |
File system block size in bytes.
The default is 1024 bytes for file system smaller than two terabytes.
For Version 7 or later disk layout file systems larger than two terabytes,
the maximum file system size is dependent on the block size.
A 32 TB file system requires a 1K block size,
an 64 TB file system requires a 2K block size,
a 128 TB file system requires a 4K block size,
and a 256 TB file system requires an 8K block size.
|
|
-o largefiles | nolargefiles | | |
Valid for the Version 4 and later 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 file system
are limited to less than two gigabytes.
The default is
largefiles.
See the
mkfs_vxfs(1M),
fsadm_vxfs(1M),
and
mount_vxfs(1M)
manual pages.
|
|
-s size |
File system size in
DEV_BSIZE
bytes
(defined in
<sys/param.h>). The default value is the size of the entire disk or disk section,
minus the swap or boot space requested.
size specifies the number of sectors in the file system.
By default,
size is specified in units of disk blocks
(DEV_BSIZE bytes).
However,
you can append
k,
K,
m,
M,
g,
G,
t, or
T to the number to indicate that the value is
in kilobytes,
megabytes,
gigabytes,
or terabytes,
respectively.
This option cannot be specified if the file system is being created on
a volume set.
