default_fs(4) File Formats default_fs(4) NAME
default_fs, fs - specify the default file system type for local or remote file systems DESCRIPTION
When file system administration commands have both specific and generic components (for example, fsck(1M)), the file system type must be specified. If it is not explicitly specified using the -F FSType command line option, the generic command looks in /etc/vfstab in order to determine the file system type, using the supplied raw or block device or mount point. If the file system type can not be determined by searching /etc/vfstab, the command will use the default file system type specified in either /etc/default/fs or /etc/dfs/dfstypes, depend- ing on whether the file system is local or remote. The default local file system type is specified in /etc/default/fs by a line of the form LOCAL=fstype (for example, LOCAL=ufs). The default remote file system type is determined by the first entry in the /etc/dfs/fstypes file. File system administration commands will determine whether the file system is local or remote by examining the specified device name. If the device name starts with ``/'' (slash), it is considered to be local; otherwise it is remote. The default file system types can be changed by editing the default files with a text editor. FILES

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
