Use: "nfs remote:path",
|
|
Short: `Serve the remote as an NFS mount`,
|
|
Long: `Create an NFS server that serves the given remote over the network.
|
|
|
|
The primary purpose for this command is to enable [mount command](/commands/rclone_mount/) on recent macOS versions where
|
|
installing FUSE is very cumbersome.
|
|
|
|
Since this is running on NFSv3, no authentication method is available. Any client
|
|
will be able to access the data. To limit access, you can use serve NFS on loopback address
|
|
and rely on secure tunnels (such as SSH). For this reason, by default, a random TCP port is chosen and loopback interface is used for the listening address;
|
|
meaning that it is only available to the local machine. If you want other machines to access the
|
|
NFS mount over local network, you need to specify the listening address and port using ` + "`--addr`" + ` flag.
|
|
|
|
Modifying files through NFS protocol requires VFS caching. Usually you will need to specify ` + "`--vfs-cache-mode`" + `
|
|
in order to be able to write to the mountpoint (full is recommended). If you don't specify VFS cache mode,
|
|
the mount will be read-only.
|
|
|
|
To serve NFS over the network use following command:
|
|
|
|
rclone serve nfs remote: --addr 0.0.0.0:$PORT --vfs-cache-mode=full
|
|
|
|
We specify a specific port that we can use in the mount command:
|
|
|
|
To mount the server under Linux/macOS, use the following command:
|
|
|
|
mount -oport=$PORT,mountport=$PORT $HOSTNAME: path/to/mountpoint
|
|
|
|
Where ` + "`$PORT`" + ` is the same port number we used in the serve nfs command.
|
|
|
|
This feature is only available on Unix platforms.
