Parameters
default volume enable Enables defaults to be used by all volumes on
the server.
default volume policy [custom |
global_rw | home_dir]
Specifies the default volume policy to the type
specified:
• Custom. Enables you to turn on or off the root
squash feature for NFS volumes from this
server. Root-squashing allows an NFS server
to map any incoming user ID 0 or guest ID 0
to another number that does not have
superuser privileges, often -2 (the nobody
user).
• Global Read-Write. Specifies a policy that
provides a trade-off of performance for data
consistency. All of the data can be accessed
from any client, including LAN based NFS
clients (which do not go through the HP EFS
WAN Accelerators) and clients using other
file protocols like CIFS. This option severely
restricts the optimizations that can be applied
without introducing consistency problems.
This is the default configuration.
• Home Directory. Specifies all accesses to
each directory are by a single user. This policy
allows aggressive caching of data and
metadata.
default volume root-squash Enables root-squashing on the volume.
direntrymap <cr> Enables the directory entry map.
ip <address> Specifies the IP address of the NFS server.
