第二步：修改ceph配置中的时间偏差阈值
* X4 ?+ w: h2 F" k( E1. 在admin部署节点修改配置参数：
# \" M, F# ]8 o; O5 R- D, I& n
# vi ~/my-cluster/ceph.conf
在global字段下添加：
6 G& G7 t$ ^% n! g% f8 y7 R
mon clock drift allowed = 2
$ x4 |! z$ n0 q- F& t: N& g5 ]0 ]mon clock drift warn backoff = 30   
2. 向需要同步的mon节点推送配置文件：
5 c8 m- m4 c. S& P
9 Z6 G1 J8 b+ `! _8 q7 |# ceph-deploy --overwrite-conf config push node{1..3}
这里是向node1 node2 node3推送，也可以后跟其它不连续节点
3. 重启mon服务（centos7环境下）

# {! ?5 W/ o. J# systemctl restart ceph-mon.target
  o: X8 I# Y; g  j% M+ i! ?4.验证：

7 F, B2 B" a, k/ N# ceph -s
