• NFS server - The IPv4 address or DNS name.
• NFS share path - Full path to the directory where the NFS file share contains the backups. The path must start with a '/'.
• NFS share protocol version - The version of NFS protocol used. Both NFS version 3 and 4.x are supported.

Verifying NFS file share

You can try out accessing the NFS file share via bash by executing the following command directly on one of the cluster's host machines.

sudo mount -t nfs -o nfsvers=MAJOR_VERSION SERVER_IP:/SHARE_PATH SOME_LOCAL_DIRECTORY -vvvv

• Replace MAJOR_VERSION with the appropriate major version number (3 or 4).
  • If you need to add the minor version (for example to specify version 4.2) then change  -o nfsvers=MAJOR_VERSION to -o nfsvers=MAJOR_VERSION,minorversion=MINOR_VERSION.
• Replace SERVER_IP with the IP address (or DNS name) of the machine hosting the file share.
• Replace SHARE_PATH with the path to the directory in the NFS file share which you want to mount.
• Replace SOME_LOCAL_DIRECTORY with an existing empty directory you want to mount your NFS file share into.

If this works, you can then see any files that exist in your file share inside the SOME_LOCAL_DIRECTORY directory.

sudo umount SOME_LOCAL_DIRECTORY

If it doesn't understand how to mount the NFS file share at all, make sure you've got the appropriate NFS client tools installed for your OS (e.g. nfs-common for Ubuntu).
