fsdb(1M) System Administration Commands fsdb(1M) NAME
fsdb - file system debugger SYNOPSIS
fsdb [-F FSType] [-V] [-o FSType-specific_options] special DESCRIPTION
fsdb is a file system debugger that allows for the manual repair of a file system after a crash. special is a special device used to indicate the file system to be debugged. fsdb is intended for experienced users only. FSType is the file system type to be debugged. Since different FSTypes have different structures and hence different debugging capabilities, the manual pages for the FSType-specific fsdb should be consulted for a more detailed description of the debugging capabilities. OPTIONS
-F Specify the FSType on which to operate. The FSType should either be specified here or be determinable from /etc/vfstab by match- ing the special with an entry in the table, or by consulting /etc/default/fs. -V Echo the complete command line, but do not execute the command. The command line is generated by using the options and arguments pro- vided by the user and adding to them information derived from /etc/vfstab. This option may be used to verify and validate the com- mand line. -o Specify FSType-specific options. USAGE
See largefile(5) for the description of the behavior of fsdb when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). FILES
/etc/default/fs default local 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

mkfs(1M) System Administration Commands mkfs(1M) 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 pro- vided 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

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 sys- tem 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. SunOS 5.11 17 Nov 2000 mkfs(1M)
