Reliable NFS Ping

In a congested network, the default timeout for an NFS ping may be too short, possibly

resulting in failed mounts. AutoFS supports the -retry= n mount option for an NFS

map entry to configure the ping timeout value. Increasing the value raises the

probability for the ping to succeed.

Supported Filesystems

AutoFS enables you to mount different types of filesystems. To mount the filesystems,

use the fstype mount option, and specify the location field of the map entry. Following

is a list of supported filesystems and the appropriate map entry:

AutoFS mount-point -fstype=autofs autofs_map_name

NOTE: You can specify another AutoFS map name in the location field

of the map-entry. This would enable AutoFS to trigger other AutoFS

mounts.

CacheFS mount-point -fstype=cachefs, cachedir=/cache_directory, backfstype=nfs

server:/source_directory

NOTE: You must ensure that the back-end filesystem, for example NFS,

must be made available. Also, the cache directory must have been created.

HFS mount-point -fstype=hfs :/device_path

NFS mount-point server:/source directory

NOTE: You must ensure that the source directory has been created and

exported on the server.

VxFS mount-point /source_directory

NOTE: You must ensure that the source directory has been created.

NOTE: The examples specified are for AutoFS maps stored in plain files. You can use

specific tools to convert the maps to other supported backends, such as NIS or LDAP.
