What’s New in This Version of AutoFS
AutoFS supports the following new features:
• LDAP Support
AutoFS supports LDAP directories for AutoFS map storage and distribution.
• NFSv4 Support
AutoFS supports NFSv4 filesystems.
• Secure NFS Support
AutoFS supports secure NFS filesystems.
• IPv6 Support
AutoFS provides support for mounting filesystems over IPv6 transports.
NOTE AutoFS also provides the features that were initially supported by the
Enhanced AutoFS product.
• On-Demand Mounting of Hierarchical Filesystems
In earlier versions, AutoFS mounted an entire set of filesystems if they were
hierarchically related. However, in HP-UX 11i v3, AutoFS mounts only those filesystems
that users access; other filesystems that are hierarchically related to these filesystems are
mounted only when they are requested. This prevents unnecessary mounting and
unmounting, and improves performance.
• Browsability
AutoFS enables a user to view the directories that can be mounted for indirect maps,
without actually mounting each filesystem.
• Concurrent mount or unmount
AutoFS performs concurrent mounts and unmounts using the multithreaded automountd
daemon. This prevents services from hanging if a server is unavailable.
• Reliable NFS ping
AutoFS supports a -retry=n mount option for an NFS map entry to configure the ping
timeout value. The default timeout value is 10 seconds. The ping command can impose a
load on the network if used during normal operations or from automated scripts.
