Remount ONTAP volumes or data shares for NFS trunking

To convert non-trunked client connections to trunked connections, existing mounts on Linux and VMware clients must be unmounted and remounted using information about LIFs.

Learn about supported clients.

Note Unmounting VMware clients is disruptive for any VMs on the datastore. An alternative would be to create a new datastore enabled for trunking, and use storage vmotion to move your VMs from the old datastore to the new one. See your VMware documentation for details.
Linux client requirements

If you are using ONTAP 9.16.1 or later and Red Hat Enterprise Linux version 8.7 or later (for RHEL 8) or 9.2 or later (for RHEL 9) as your Linux client, only one mount point is required for the trunking group. Mount the exported volumes with this command, using the trunkdiscovery option:

mount <lif_ip>:<volume_name> </mount_path> -o trunkdiscovery,vers=4.1
Cli
Copy

Otherwise, a separate mount point is required for each connection in the trunking group. Mount the exported volumes with commands similar to the following, using the max_connect option:

mount <lif1_ip>:<volume_name> </mount_path1> -o vers=4.1,max_connect=16
Cli
Copy
mount <lif2_ip>:<volume_name> </mount_path2> -o vers=4.1,max_connect=16
Cli
Copy

The version (vers) value should be 4.1 or later.

The max_connect value corresponds to the number of connections in the trunking group.
