Check if the operating system supports EPOLLEXCLUSIVE

我在虚拟机上安装tibd集群,然后出现了这个问题

fatal: [192.168.91.22]: FAILED! => {“changed”: true, “cmd”: “/sgk/tidb/deply/epollexclusive”, “delta”: “0:00:00.133292”, “end”: “2019-08-08 07:53:38.461208”, “msg”: “non-zero return code”, “rc”: 1, “start”: “2019-08-08 07:53:38.327916”, “stderr”: “”, “stderr_lines”: [], “stdout”: “epoll_ctl with EPOLLEXCLUSIVE | EPOLLONESHOT succeeded. This is evidence of no EPOLLEXCLUSIVE support. Not using epollex polling engine.False: epollexclusive is not available”, “stdout_lines”: [“epoll_ctl with EPOLLEXCLUSIVE | EPOLLONESHOT succeeded. This is evidence of no EPOLLEXCLUSIVE support. Not using epollex polling engine.False: epollexclusive is not available”]} ,请问下这个是哪里出错了,谢谢
