fs_wrapper - configuration and binary files used by file system administration commands SYNOPSIS
FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... FStype] ... DESCRIPTION
The commands listed in the SYNOPSIS can operate on different types of file systems. Each command (except for reads file system specific configuration files that control the command's behavior, and invokes a file system specific binary file to do the actual work. FStype is the file system type as optionally specified on the command line. If FStype is not given, then the file system type is determined from by matching an entry in this file with a device provided with the command (see individual commands for details of usage). Administrators may also define a default file system type for the above commands via the file If this file exists, and contains the line: (e.g., then the above commands will assume the FStype given in unless an FStype is provided on the command line or is in The default file system specification is provided to maintain compatibility with pre-10.0 invocations of the commands. See the FILES section for a list of the files used. WARNINGS
The configuration files are supplied by HP or by other file system vendors. They are not meant to be edited by System Administrators. Corruption or removal of these files may lead to strange behavior, including the inability to boot. The format of the configuration file is subject to change. The file system specific binary files are not normally executed directly. However, if the configuration files become unusable, direct exe- cution of these binary files may be a useful step in repairing and running the system again. The binary files accept the same arguments as the commands by which they are executed. The command is a special case. This command currently does not read a configuration file, and does not execute a file system specific binary file if FStype is or The binary that handles these FStypes also processes other FStypes and calls the file system specific command if appropriate. For historical reasons, the binary files also handle and so there are no separate binary files for the latter two file systems. The commands (except will not work if they are renamed, because they are symbolically linked to a single executable FILES

mount, umount - mount and unmount file systems SYNOPSIS
FStype] FStype] specific_options] {special|directory} FStype] specific_options] special directory {special|directory} FStype] host] DESCRIPTION
The command mounts file systems. Only a superuser can mount file systems. Other users can use to list mounted file systems. The command attaches special, a removable file system, to directory, a directory on the file tree. directory, which must already exist, will become the name of the root of the newly mounted file system. special and directory must be given as absolute path names. If either special or directory is omitted, attempts to determine the missing value from an entry in the file. can be invoked on any removable file system, except If is invoked without any arguments, it lists all of the mounted file systems from the file system mount table, The command unmounts mounted file systems. Only a superuser can unmount file systems. Options (mount) The command recognizes the following options: Attempt to mount all file systems described in All optional fields in must be included and supported. If the option is specified, all file systems in with that FStype are mounted. If is specified in an entry's option list, this entry is skipped. File systems are not neces- sarily mounted in the order listed in Verbose mode. Write a message to the standard output indicating which file system is being mounted. Specify FStype, the file system type on which to operate. See fstyp(1M). If this option is not included on the command line, then it is determined from either by matching special with an entry in that file, or from file system statis- tics of special, obtained by (see statfsdev(3C)). Unmount only those file systems listed in that are remote-mounted from host. Limit actions to local file systems only. Specify options specific to each file system type. specific_options is a list of comma separated suboptions and/or keyword/attribute pairs intended for a FStype-spe- cific version of the command. See the FStype-specific manual entries for a description of the specific_options sup- ported, if any. Report the list of mounted file systems in the format. Prevent the display of error messages that result from an attempt to mount already mounted file systems. Mount the specified file system as read-only. Physically write-protected file systems must be mounted in this way or errors occur when access times are updated, whether or not any explicit write is attempted. Report the regular output with file system type and flags; however, the directory and special fields are reversed. Echo the completed command line, but perform no other action. The command line is generated by incorporating the user-specified options and other information derived from This option allows the user to verify the command line. Options (umount) The command recognizes the following options: Attempt to unmount all file systems described in All optional fields in must be included and supported. If FStype is specified, all file systems in with that FStype are unmounted. File systems are not necessarily unmounted in the order listed in Forced unmount. A forced unmount is one which will occur regardless of activity on the file system. Not supported by all file system types. See file system type specific man pages for more information. If the file system type man page does not men- tion forced unmount, then it is not supported for that file system type. Specify FStype, the file system type on which to operate. If this option is not included on the command line, then it is determined from by matching special with an entry in that file. If no match is found, the command fails. Verbose mode. Write a message to standard output indicating which file system is being unmounted. Echo the completed command line, but perform no other action. The command line is generated by incorporating the user-specified options and other information derived from This option allows the user to verify the command line. EXAMPLES
