2. Network File System Administration (Tasks)
This section provides information about new features in releases of the Oracle Solaris OS.
The Oracle Solaris 11.1 release includes the following enhancements:
A new property has been added to the /network/nfs/server:default service which controls the amount of information that the showmount command displays to remote clients. For more information see Example 2-3 and showmount Command.
Support for FedFS referrals has been added. This permits referral information for several servers to be centralized in LDAP. See Administering FedFS for more information.
The following enhancements are included in the Oracle Solaris 11 release:
The configuration parameters that used to be set by editing the /etc/default/autofs and /etc/default/nfs can now be set in the Service Management Facility (SMF) repository. See the descriptions of the new SMF parameters in procedures that use them, as well as the descriptions of the daemons that use them:
The NFS service provides support for mirror mounts. Mirror mounts enable an NFSv4 client to traverse shared file system mount points in the server namespace. For NFSv4 mounts, the automounter will perform a mount of the server namespace root and rely on mirror mounts to access its file systems. The main advantage that mirror mounts offer over the traditional automounter is that mounting a file system using mirror mounts does not require the overhead associated with administering automount maps. Mirror mounts provide these features:
Namespace changes are immediately visible to all clients.
New shared file systems are discovered instantly and mounted automatically.
File systems unmount automatically after a designated inactivity period.
For more information about mirror mounts, refer to the following:
NFS referrals have been added to the NFS service. Referrals are server-based redirections that an NFSv4 client can follow to find a file system. The NFS server supports referrals created by the nfsref(1M)command, and the NFSv4 client will follow them to mount the file system from the actual location. This facility can be used to replace many uses of the automounter, with creation of referrals replacing the editing of automounter map. NFS referrals provide these features:
All of the features of mirror mounts listed above
Automounter-like functionality without any dependence on the automounter.
No setup required at either the client or server.
For more information about NFS referrals, see:
The ability to mount the per-DNS-domain root of a Federated File System name space has been added. This mount point can be used with NFS referrals to bridge from one file server to another, building an arbitrarily large namespace. For more information see:
The sharectl utility is included. This utility enables you to configure and manage file sharing protocols, such as NFS. For example, this utility allows you to set client and server operational properties, display property values for a specific protocol, and obtain the status of a protocol. For more information, see the sharectl(1M) man page and sharectl Command.
The way an NFS version 4 domain can be defined has changed since the initial Solaris 10 release. See Configuring an NFS Version 4 Default Domain in the Oracle Solaris 11 Release for more information.
