This is especially useful for returning disk space to the filesystem when using loopback devices. +* `fs_type` - defines the file system to use for snapshot device mount. Valid values are `ext4` and `xfs`. Defaults to `ext4` if unspecified. +* `fs_options` - optionally defines the file system options. This is currently only applicable to `ext4` file system. Pool name and base image size are required snapshotter parameters.
