How to Replicate Shared Files Across Several Servers

The best way to share replicated file systems that are read-only is to use failover. See "Client-Side Failover" for a discussion of failover.

Modify the entry to create the list of all replica servers as a comma-separated list:

bin     aa,bb,cc,dd:/export/local/bin/$CPU

Autofs chooses the nearest server. If a server has several network interfaces, then list each interface. Autofs chooses the nearest interface to the client, avoiding unnecessary routing of NFS traffic.
