PG运行过程中出现归档失败的情况，并在日志文件中存在报错。

报错如下：

cp: writing `/arch/20171204/000000010000000000000002': No space left on device
LOG:  archive command failed with exit code 1

WARNING:  archiving transaction log file "000000010000000000000002" failed too many times, will try again later

原因是归档日志所在文件系统/arch空间不足。

通过清理该文件系统下过期的临时文件，或将归档日志存放至更大的系统空间中。
