The HNAS server supports NFS versions 2, 3, 4, and 4.1. By default, the maximum version supported is version 3, which means that the server supports versions 2 and 3 by default. You can change the maximum supported NFS version by using the CLI command nfs-max-supported-version.
For example, To change the maximum supported version to NFSv4, run nfs-max-supported-version 4. Similarly, run nfs-max-supported-version 4.1 to set the maximum supported version to NFS v4.1.
If you set the maximum supported version to 4.1, the HNAS server enables support for NFS versions 2, 3, 4 and 4.1.
Note: NFS v4.1 is supported on HNAS 5000 Series only.
