Features Introduced in ONCplus B.11.31_LR
The following new features were introduced in ONCplus B.11.31_LR:
New NFS Features in ONCplus B.11.31_LR
NFS supports the following new features:
• NFS Version 4 Protocol (NFSv4)
NFSv4 is an IETF standard protocol that provides the following features:
— COMPOUND Procedure
In NFSv4, related RPC requests are grouped into a single RPC procedure known as the
COMPOUND procedure.
The COMPOUND procedure decreases transport and security overhead because of
fewer over-the-wire trips between the client and the server. This feature is transparent
to the user.
— Delegation
In NFSv4, the server can delegate certain responsibilities such as OPEN, CLOSE, LOCK,
LOCKU, READ, and WRITE to the client. Delegation enables a client to locally service
operations without immediate interaction with the server. Delegations can be revoked
by the server. When another client requests access to the same file, the server revokes
the delegation from the first client and grants it to the second client.
NOTE: Delegations are disabled by default. If delegations are enabled, they are only
supported by applications that access the delegated files remotely via NFS clients.
Allowing local access and enabling delegation on a file can corrupt the file.
— ACLs
An Access Control List (ACL) offers stronger file security by enabling the owner of the
file to define file permissions for the file owner, the group, and other specific users and
groups.
— String Identifiers
In NFSv4, exchange of user ID (UID) and group ID (GID) information between the client
and server is in the form of strings. The nfsmapid daemon maps UID and GID values
from integer to string and string to integer.
