pgmap v6: 72 pgs, 2 pools, 0 bytes data, 0 objects

docker exec monnode ceph health detail | grep inactive
得到的结果是
HEALTH_WARN 72 pgs stuck inactive; 72 pgs stuck unclean
pg 0.2d is stuck inactive since forever, current state creating, last acting []
pg 0.2c is stuck inactive since forever, current state creating, last acting []

pg 0.11 is stuck inactive since forever, current state creating, last acting []
重启也没有效果，而且网关镜像连接不稳定会断

同学你好，如果重启也无法解决问题，尝试一下手动去重新activate那些有问题的node，可以参考下这里：https://stackoverflow.com/questions/44819494/ceph-370-pgs-are-stuck-inactive-for-more-than-300-seconds
如果依然无法解决，可能是其他一些比较隐蔽原因造成的问题。建议先跳过这部分内容，等后面更重要的微服务相关内容学习完之后，再回来研究ceph的部署。
