+The built-in `local` driver on Linux accepts options similar to the linux `mount` command. You can provide multiple options by passing the `--opt` flag multiple times. Some `mount` options (such as the `o` option) can take a comma-separated list of options. Complete list of available mount options can be found [here](http://man7.org/linux/man-pages/man8/mount.8.html).

+For example, the following creates a `tmpfs` volume called `foo` with a size of 100 megabyte and `uid` of 1000.
+
+```bash
+$ docker volume create --driver local --opt type=tmpfs --opt device=tmpfs --opt o=size=100m,uid=1000 --name foo
+```
+
+Another example that uses `btrfs`:
```bash
-$ docker volume create --driver local --opt type=tmpfs --opt device=tmpfs --opt o=size=100m,uid=1000
+$ docker volume create --driver local --opt type=btrfs --opt device=/dev/sda2 --name foo
```
-Another example:
+Another example that uses `nfs` to mount the `/path/to/dir` in `rw` mode from `192.168.1.1`:
```bash
-$ docker volume create --driver local --opt type=btrfs --opt device=/dev/sda2
+$ docker volume create --driver local --opt type=nfs --opt o=addr=192.168.1.1,rw --opt device=:/path/to/dir --name foo
