NAME
newfs_vxfs: newfs - create a new VxFS file system
SYNOPSIS
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:
-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 mega-
bytes. -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 sys-
tem 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 sys-
tem 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
