今天在線上環境使用cp.push模組拉取minion端檔案時，出現如下錯誤

# salt 192.168.xxx.xxx cp.push   /etc/fstab
192.168.xxx.xxx:
    The minion function caused an exception: Traceback (most recent call last):
      File "/usr/lib/python2.6/site-packages/salt/minion.py", line 1332, in _thread_return
        return_data = executor.execute()
      File 
 
"/usr/lib/python2.6/site-packages/salt/executors/direct_call.py", line 28, in execute
        return self.func(*self.args, **self.kwargs)
      File "/usr/lib/python2.6/site-packages/salt/modules/cp.py", line 876, in push_dir
        ret = push(tmpfile, upload_path=tmpupload_path)
      File "/usr/lib/python2.6/site-packages/salt/modules/cp.py
 
", line 799, in push
        load_path_list = os.path.split(load_path_split_drive)
      File "/usr/lib64/python2.6/posixpath.py", line 82, in split
        i = p.rfind('/') + 1
    AttributeError: 'tuple' object has no attribute 'rfind'

然後在測試環境使用cp.push模組正常，

# salt 192.168.62.200  cp.push /etc/fstab 
 

192.168.62.200:
    True

對比測試環境跟線上環境salt版本,

線上環境

# salt --version
salt 2016.3.3 (Boron)

測試環境

# salt --version
salt 2016.11.3 (Carbon)

版本不一致,對比cp模組原始碼，發現報錯程式碼行前後有一些差異

將線上環境/usr/lib/python2.6/site-packages/salt/modules/cp.py 備份並刪除799行程式碼中的冒號(:) 重新執行命令發現正常拉去minion檔案

# salt 192.168.xxx.xxx cp.push   /etc/fstab  
192.168.xxx.xxx:
