ONCplus B.11.31.01 Release Notes

• 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.
• NFS loopback mount
By default, AutoFS uses the Local File Systems (LOFS) mounts for locally mounted
filesystems. AutoFS provides an option to allow loopback NFS mounts for the local mount.
Use this option in the High Availability NFS environments.
• Client-side Failover Support
AutoFS enables a mounted NFS read-only filesystem to transparently switch over to an
alternate server if the current server goes down.
• Backend Support
AutoFS supports the storage and distribution of AutoFS maps in the following:
— Files
— Network Information Service (NIS)
— Lightweight Data Access Protocol (LDAP)
• Filesystem Support
AutoFS supports the automatic mounting and unmounting of the following filesystems:
— NFS (All versions including NFSv4)
— CacheFS
— HFS
— VxFS
— CIFS
— AutoFS
• Secure NFS Support
AutoFS supports secure NFS filesystems if the NFS client supports mounting of secure
directories.
• IPv6 Support
AutoFS provides support for mounting filesystems over IPv6 transports.
New CacheFS Features in ONCplus B.11.31_LR
CacheFS supports the following features:
• Complete Binary Caching
CacheFS is commonly used to manage application binaries. This feature enables you to cache
a complete binary file in the local cache. To force a client to cache a complete copy of the
accessed binary file, use the rpages mount option. For more information on the rpages
mount option, see the NFS Services Administrator’s Guide.
• Cache Pre-Loading
This feature enables you to pre-load or pack specific files and directories in the cache. Packing
files and directories enables you to have greater control over the cache contents, because it
ensures that the specified files are always present in the cache. Use the cachefspack
command to pack specific files and directories.
