NAS OS 4.x - How to set up a VMware NFS Datastore
- Log in to the Seagate NAS Welcome page as an admin or a user with administrative privileges.
- On the Home page click the Device Manager icon.
- Click Services under Customize.
- Hover the mouse cursor over the the NFS Service and Click the Edit button and click Start.
- A green light will indicate the service has started.
View NFS options
- Click the NFS Edit button and notice the Start option has been replaced with Stop.
- Click Edit and Share access. The NFS service is enabled on all shares by default. This means that when a new share is created, NFS is enabled on any new share.
- Click Edit and Advanced parameters. This mode can be changed from Asynchronous to Synchronous. The default is Asynchronous. Available on all LANs is the default and this means that if the NAS has two network ports NFS is available for both. Click Cancel.
Asynchronous vs. Synchronous behavior in NFS
"Asynchronous" yields better performance at the cost of possible data corruption if the server reboots while still holding unwritten data. The reason is the Async option instructs the server to lie to the client, telling the client that all data has indeed been written to stable storage.
With Synchronous behavior the server will not complete (reply to the client) until the local file system has written all data/metadata to the disk.
Create a share on the Seagate NAS or use an existing share
- Click Shares on the left. A new public share can be created or an existing share can be used.
- To create a new share click the Add share button.
- Enter a Name, Description, and select Public, then click Next.
- Check to see if NFS is enabled on the new or used share by clicking Edit to the right of the Share name, then Services. Verify the NFS service is checked then click Save
In this example the new share’s name is VMware. NFS is checked.
