现象
GreenPlum查询数据库某个表，频繁报错：
1 2 3 4 | could not open file "base/231962/24824104": No such file or directory (seg44 slice2 192.168.163.54:6014 pid=1499766) could not open file "base/231962/24824106": No such file or directory (seg43 192.168.163.54:6013 pid=1493896) |
将这个表从备份中恢复回来后，还是报错。

解决
从mirror实例上拷贝回去。
