CHAPTER 20 Distributed File System Administration

20.4 SunOS 5.X

SunOS 5.X uses a common set of commands and files to administer both the Network File System (NFS) and the Remote File Sharing (RFS) system. This combination is known as the Distributed File System (DFS). These common set of commands for DFS replace the individual commands for NFS and RFS of SunOS 4.X. Through DFS you can share files, directories, and devices over the network.

The operative word with DFS is sharing. With DFS we share file systems, rather than export them. /etc/exports and exportfs are gone. In place of these files we have the control files in the /etc/dfs directory and the share and shareall commands. The files in /etc/dfs are:

20.4.1 - /etc/dfs/dfstab
20.4.2 - /etc/dfs/fstypes
20.4.3 - /etc/dfs/sharetab
20.4.4 - Daemons
20.4.5 - The Automount File System, autofs
20.4.6 - Utilities
