mkfs - construct a file system
mkfs [ -F FSType ] [ generic_options
] [ -o FSType-specific_options ] raw_device_file [ operands ]
SUNWcsu
mkfs constructs a file system on the the raw_device_file
by calling the specific mkfs module indicated by -F FSType.
Note: ufs file
systems are normally created with the newfs(1M)
command.
generic_options
are independent of file system type. FSType-specific_options is a comma-separated
list of keyword=value pairs (with no intervening spaces), which are FSType-specific.
raw_device_file specifies the disk partition on which to write the file
system. It is required and must be the first argument following the specific_options
(if any). operands are FSType-specific. See the FSType-specific manual page
of mkfs (for example, mkfs_ufs(1M)
) for a detailed description.
The
following are the generic options for mkfs:
- -F
- Specify the FSType to be
constructed. If -F is not specified, the FSType is determined from /etc/vfstab
by matching the raw_device_file with a vfstab entry, or by consulting
the /etc/default/fs file.
- -V
- Echo the complete command line, but do not
execute the command. The command line is generated by using the options
and arguments provided and adding to them information derived from /etc/vfstab
or /etc/default/fs. This option may be used to verify and validate the
command line.
- -m
- Return the command line which was used to create the file
system. The file system must already exist. This option provides a means
of determining the command used in constructing the file system.
- -o
- Specify
FSType-specific options. See the manual page for the mkfs module specific
to the file system type.
- /etc/default/fs
- Default file system type.
Default values can be set for the following flags in /etc/default/fs. For
example: LOCAL=ufs
- LOCAL:
- The default partition for a command if no FSType
is specified.
- /etc/vfstab
- List of default parameters for each file system
newfs(1M)
, vfstab(4)
