NAME

mkfs − construct a file system

SYNOPSIS

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

[ operands ]

AVAILABILITY

SUNWcsu

DESCRIPTION

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. 

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.
