Which Automounter makes sense for

your environment?

automount

autofs

UDP or TCP transportsUDP transport only

Can manage CacheFS mountsCannot manage CacheFS

Can be used with HA/NFS,

but precautions should be

taken to ensure correct behavior

Safe for use with HA/NFS

(i.e. ServiceGuard)

NFS PV2 or PV3NFS PV2 only

Automount AutoFS

Environments where Automount is Recommended

Given the earlier list of differences between automount and AutoFS, there is

really only one environment where automount holds an advantage over AutoFS

– on NFS servers running Highly Available NFS (i.e. ServiceGuard). Of course,

if your environment only requires the use of NFS PV2, the UDP transport, 8KB

read/write sizes, and does not need to manage CacheFS mounts, the legacy

automounter will work fine.

Environments where AutoFS is Recommended

Since AutoFS includes all of the features provided by the legacy automounter

and adds several new features, most NFS environments will benefit from using

AutoFS in place of automounter. Any customers needing to integrate support

for NFS PV3, NFS/TCP, or CacheFS into their automount environment will need

to use AutoFS.
