第二步：修改ceph配置中的时间偏差阈值
% J* D5 a6 I: _6 r+ d' M1. 在admin部署节点修改配置参数：
; J$ |6 _+ g* a  P
# vi ~/my-cluster/ceph.conf
在global字段下添加：

mon clock drift allowed = 2
" E# u) V; O* w4 fmon clock drift warn backoff = 30   
2. 向需要同步的mon节点推送配置文件：
& L3 q& s! y7 E
# E5 \6 [6 w! N7 _$ G# 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
' T/ y  U$ `5 @7 }* N! P* w. h3 v3. 重启mon服务（centos7环境下）
! C; O" n" l' H* R
# systemctl restart ceph-mon.target
. k2 ^9 V- j* j+ m4.验证：

# ceph -s
