DFS commands and files

The DFS Administration Utilities package installs several commands: share, unshare, shareall, unshareall, dfshares, and dfmounts. In addition to these commands, DFS Administration uses a number of files and commands installed by the other packages.

All the files and commands relevant to DFS administration are described in this section. Files and commands that operate on all file system types are described in this section only as they relate to administering distributed file systems.

The DFS Administration files are:

• /etc/dfs/fstypes, which registers the distributed file system packages you have installed on your system and establishes the default package (the first line in this file is the default package). The fstypes file is created by the distributed file system package you install first.

• /etc/dfs/dfstab, which allows you to share a resource or a set of resources automatically when you enter system state 3.

• /etc/vfstab, which allows you to mount resources automatically when you enter system state 3.

• /etc/dfs/sharetab, which logs the resources currently shared on your system. The sharetab file is created by the share command and does not require handling by an administrator.

• /etc/mnttab, which logs the file systems currently mounted by your system, including remote file systems and directories. The mnttab file is created by the mount command and does not require handling by an administrator.

• share(1Mnfs), which allows you to make a resource available for mounting by clients or to display a list of the resources on your system that are currently shared.

• unshare(1Mnfs), which allows you to make a previously available resource unavailable for mounting by clients.

• shareall(1M), which executes a script that shares a predetermined set of resources listed in /etc/dfs/dfstab.

• unshareall (see shareall(1M)), which executes a script that unshares all currently shared resources listed in /etc/dfs/dfstab.

• mount(1Mnfs), which allows you to mount a remote resource on your system or to display a list of resources, both local and remote, that are currently mounted on your system.

• umount (see mount(1Mnfs)), which allows you to remove a remote resource you previously mounted.

• mountall(1M), which executes a script that mounts a predetermined set of resources.

• umountall (see mountall(1M)), which executes a script that unmounts all currently mounted resources.

• dfshares(1nfs), which displays a list of remote resources that are available to you, as well as a list of local resources that are currently shared.

• dfmounts(1nfs), which shows you which local resources are mounted by which clients.
