nfs

- file containing parameter values for NFS-related daemons

Synopsis

/etc/default/nfs

Description

The settings formerly managed by the nfs file have been moved to SMF properties and are now managed by sharectl(1M). The functionality described here is provided for backward compatibility only.

The nfs file resides in directory /etc/default and provides startup parameters for the nfsd(1M), nfsmapid(1M), mountd(1M), and lockd(1M) daemons.

The nfs file format is ASCII; comment lines begin with the crosshatch (#) character. Parameters consist of a keyword followed by an equals (=) sign followed by the parameter value, of the form:

keyword=value

The following parameters are currently supported in the nfs file:

NFS_CLIENT_VERSMIN=num
NFS_CLIENT_VERSMAX=num

The NFS client only uses NFS versions in the range specified by these variables. Valid values or versions are: 2, 3, and 4. By default these variables are unspecified (commented out) and the client's default minimum is Version 2. The default maximum is Version 4. You can override this range on a per-mount basis by using the -o vers= option to mount_nfs(1M).

NFS_SERVER_VERSMIN=num
NFS_SERVER_VERSMAX=num

The NFS server only uses NFS versions in the range specified by these variables. Valid values or versions are: 2, 3, and 4. As with the client, the default is to leave these variables commented out and the default minimum version is 2, while the default maximum version is 4.

NFS_SERVER_DELEGATION=on | off

By default, this variable is commented out and the NFS server provides delegations to clients. The user can turn off delegations for all exported filesystems by setting this variable to off (case-sensitive). This variable only applies to NFS Version 4.

NFSMAPID_DOMAIN=domain-string

By default, nfsmapid uses the DNS domain of the system. This setting overrides the default. This domain is used for identifying user and group attribute strings in the NFS Version 4 protocol. Clients and servers must match with this domain for operation to proceed normally. This variable only applies to NFS Version 4. See “Setting NFSMAPID_DOMAIN,” below for further details.

NFSD_MAX_CONNECTIONS=num

Sets the maximum number of concurrent, connection-oriented connections. The default is unlimited and is obtained by not setting (that is, commenting out) NFSD_MAX_CONNECTIONS. Equivalent to the -c option in nfsd.

NFSD_LISTEN_BACKLOG=num

Set connection queue length for the NFS over a connection-oriented transport. The default value is 32, meaning 32 entries in the queue. Equivalent to the -l option in nfsd.

NFSD_PROTOCOL=ALL

Start nfsd over the specified protocol only. Equivalent to the -p option in nfsd. ALL is equivalent to -a on the nfsd command line. Mutually exclusive of NFSD_DEVICE. One or the other of NFSD_DEVICE and NFSD_PROTOCOL must be commented out. For the UDP protocol, only version 2 and version 3 service is established. NFS Version 4 is not supported for the UDP protocol.

NFSD_DEVICE=devname

Start NFS daemon for the transport specified by the given device only. Equivalent to the -t option in nfsd. Mutually exclusive of NFSD_PROTOCOL. One or the other of NFSD_DEVICE and NFSD_PROTOCOL must be commented out.

NFSD_SERVERS=num

Maximum number of concurrent NFS requests. Equivalent to last numeric argument on the nfsd command line. The default is 1024.

LOCKD_LISTEN_BACKLOG=num

Set connection queue length for lockd over a connection-oriented transport. The default and minimum value is 32.

LOCKD_SERVERS=num

Maximum number of concurrent lockd requests. The default is 1024.

LOCKD_RETRANSMIT_TIMEOUT=num

Retransmit timeout, in seconds, before lockd retries. The default is 5.

GRACE_PERIOD=num

Grace period, in seconds, that all clients (both NLM and NFSv4) have to reclaim locks after a server reboot. This parameter also controls the NFSv4 lease interval and overrides the deprecated setting LOCKD_GRACE_PERIOD. The default is 90.

LOCKD_GRACE_PERIOD=num

Deprecated. Same as GRACE_PERIOD=num above. The default is 90.

Setting NFSMAPID_DOMAIN

As described above, the setting for NFSMAPID_DOMAIN overrides the domain used by nfsmapid(1M) for building and comparing outbound and inbound attribute strings, respectively. This setting overrides any other mechanism for setting the NFSv4 domain. In the absence of a NFSMAPID_DOMAIN setting, the nfsmapid(1M) daemon determines the NFSv4 domain as follows:

If a domainname is still not obtained following all of the preceding steps, nfsmapid has no domain configured. This results in the following behavior:

Interaction with Location Profiles

The NFS domain property is managed in Location profiles (refer to netcfg(1M) for more information about location profiles). These profiles are either fixed, meaning the network configuration is being managed in the traditional way, or reactive, meaning the network configuration is being managed automatically, reacting to changes in the network environment according to policy rules specified in the profiles.

When a fixed location (there can currently be only one, the DefaultFixed location) is active, changes made to the SMF repository will be applied to the location when it is disabled, and thus will be restored if that location is later re-enabled.

When a reactive location is active, changes should not be applied directly to the SMF repository; these changes will not be preserved in the location profile, and will thus be lost if the location is disabled, or if the system's network configuration, as managed by svc:/network/physical:default and svc:/network/location:default, is refreshed or restarted. Changes should instead be applied to the location itself, using the netcfg(1M) command; this will save the change to the location profile repository, and will also apply it to the SMF repository (if the change is made to the currently active location).

The NFS domain setting is stored in the nfsv4-domain property of a location profile.
