Attributes for NFS agent

Table: Optional attributes for AIX

Optional attribute

Description

Nservers

Specifies the number of concurrent NFS requests the server can handle.

Type and dimension: integer-scalar

Default: 10

NFSv4Root

Root directory of the NFSv4 pseudo file system to be exported. All exports should have a path relative to the path specified by this attribute. You can explicitly create the NFSv4 pseudo file system by specifying the exname option of the exportfs command in the Options attribute of the Share resource.

If you want to export file systems with NFSv4 protocols and do not want to explicitly create NFSv4 pseudo file system by using the exname option, then set NFSv4Root to "/".

Required for filesystems to be exported with v4 protocol.

Type and dimension: string-scalar

NFSSecurity

If the value of this attribute is 1, the gssd daemon starts.

You must configure the type of security that NFS supports, for example: Kerberos.

Type and dimension: boolean-scalar

Default: 0

GracePeriod

Specifies the grace period, in seconds, for which the server allows lock recovery.

Required for NFS lock recovery.

Type and dimension: integer-scalar

Default: 90

LockFileTimeout

Specify the amount of time required, in seconds, for the service group to go online. The agent uses this attribute to synchronize the starting and stopping of daemons between multiple service groups.

Type and dimension: integer-scalar

Default: 180

Example: "240"

Protocol

Specify the protocol to run the nfsd daemon. The following are the valid values:

  • tcp

  • udp

  • all

The agent uses this attribute to ensure that the NFS daemon is running using the specified protocol.

Note:

VCS overrides any change to the NFS protocol outside of VCS control, so you must not change the NFS protocol outside of VCS control.

Type and dimension: string-scalar

Default: all

Example: tcp
