NFSv4 is available starting in 6.0.2. Initial NFSv4 support is limited to target/staging hosts running Redhat 7 or later. The Appdata data platform is also excluded from using NFSv4. The target/staging hosts required additional configuration changes before NFSv4 can be used, see NFSv4 Only - Enabling Recover Lost Locks for more information.
NFSv4 is disabled by default, however, Delphix Engines can opt-in to enable v4. A new CLI service for NFS is provided to change the opt-in setting to an automatic mode where the Engine will use v4 where supported.
Possible values for the CLI setting are:
AUTOMATIC: Data sources will be mounted using NFSv4 where possible, or NFSv3 when NFSv4 is not possible.
NFSv3: Forces all mounts to be done over NFSv3.
Ssh into the engine as a sysadmin user, the admin UI does not offer control over NFS services.
Change the directory to service, then to nfs.
delphix > cd service delphix service > cd nfs
Update the mountVersion option to AUTOMATIC.
delphix service nfs> ls Properties type: NfsConfig mountVersion: AUTOMATIC Operations update delphix service userInterface > update delphix service userInterface update *> set mountVersion=AUTOMATIC delphix service userInterface update *> commit delphix service nfs> exit
