NAME

mkfs - construct a file system
 

SYNOPSIS

mkfs [-F FSType] [generic_options] 
    [-o FSType-specific_options] raw_device_file 
    [operands]

DESCRIPTION

The mkfs utility constructs a file system on 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.  

OPTIONS

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.

USAGE

See largefile(5) for the description of the behavior of mkfs when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).  

FILES

/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

ATTRIBUTES

NOTES

This command might not be supported for all FSTypes.

You can use lofiadm to create a file that appears to a mkfs command as a raw device. You can then use a mkfs command to create a file system on that device. See lofiadm(1M) for examples of creating a UFS and a PC (FAT) file system (using mkfs_ufs(1M) and mkfs_pcfs(1M)) on a device created by lofiadm.
