Question

我是Sails JS和船长磁盘文件上传的新手。如果上传被取消或请求中止，则该过程不会释放部分上传的文件。

我尝试上传1 GB的文件。上传我的根磁盘之前，可用大小为81GB 请求中止问题后，我已删除文件。但是磁盘可用大小仍显示为80GB。如果重新启动服务器，则磁盘可用大小将增加到1GB。

upload: function  (req, res) {

      var tmp_file_name = "test1.gz"
      console.log("Upload Files: " + tmp_file_name)
      req.file('avatar').upload({
        maxBytes: 10000000000,
        saveAs: tmp_file_name
    },function onUploadComplete(err, uploadedFiles) {        
        if (err) {          
          var file_uploaded = process.cwd() + "/.tmp/uploads/" + tmp_file_name;
          console.log("Deleting Files: " + file_uploaded)
          deleteFile(file_uploaded);
          return res.negotiate(err) //res.serverError(err);
        } else {
        return res.json({
          message: uploadedFiles.length + ' file(s) uploaded successfully!',
          files: uploadedFiles
        });
      }})
}

遇到下述错误

删除文件lsof命令后，该命令显示进程正在保存部分上载的文件。
