Enterprise File Storage - NFS Client considerations

Objective

Find out how to enable read/write access to your Enterprise File Storage from specific NFS clients.

Requirements

• An Enterprise File Storage solution

Instructions

Microsoft Windows NFS Clients

Ensure that the Windows user who is used to access your Enterprise File Storage has sufficient rights

This is because the UID/GID pair must be configured to 0 (root unix right).

If this is not the case, you will have errors accessing your Enterprise File Storage because, when NFS is authorized on a Windows machine, a UNIX user is created with the UID and the default GID at -2 (or 4294967294).

As a workaround, the UID and GID can be forced to 0 on the Windows machine that accesses your Enterprise File Storage.

• Start the registry editor on the client machine.
• Locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default.
• Create two DWORD values, AnonymousUid and AnonymousGid.
• Set these values on the UID and GID to 0.
• Restart the NFS service on the client machine.

Request activation of the "showmount" feature from OVHcloud support

For security reasons, the "showmount" option to list the shares available on an NFS server is disabled by default. However, if you get "invalid device error" errors during certain write operations, or if you are using an application that absolutely must use this feature, open an OVHcloud support ticket to request the feature to be enabled exceptionally.
