NAME
newfs - create a new VxFS file system
SYNOPSIS
/usr/sbin/newfs [-F vxfs][-B][-O disk_type][-R swap][-V][-v]
[mkfs_vxfs_options] special
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:
-F vxfs Specify the file-system type vxfs.
-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).
-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 mega-
bytes. -R cannot be used if the file-system size is also specified using -s
(see
mkfs_vxfs options below).
-V Echo the completed command line, but do not execute the command. 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.
-v Specify verbose mode. newfs prints out its actions, including the parameters
passed to mkfs.
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.
-o largefiles | nolargefiles
Valid only for the Version 3 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 giga-
bytes 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.
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
