How Mirror Mounts Work
The Oracle Solaris 11 release includes a new mounting facility called mirror mounts. Mirror mounts allow an NFS Version 4 client to access files in a file system as soon as the file system is shared on an NFS Version 4 server. The files can be accessed without the overhead of using the mount
command or updating autofs maps. In effect, after an NFS Version 4 file system is mounted on a client, any other file systems from that server can also
be mounted.
Generally, using the mirror mounts facility is optimal for your NFS Version 4 clients except when you need to do the following:
-
Use a different hierarchy on the client than exists on the server
-
Use different mount options than those of the parent file system
