检查mon状态
如果集群中有多个 Mon（很可能），你启动集群后、读写数据前应该检查 Mon 法定人数状态。运行着多个 Mon 时必须形成法定人数，最好周期性地检查 Mon 状态来确定它们在运行。
要查看 Mon map，执行下面的命令：
[root@ceph01 ~]# ceph mon stat
e3: 3 mons at {ceph01=[v2:192.168.11.101:3300/0,v1:192.168.11.101:6789/0],ceph02=[v2:192.168.11.102:3300/0,v1:192.168.11.102:6789/0],ceph03=[v2:192.168.11.103:3300/0,v1:192.168.11.103:6789/0]}, election epoch 1152, leader 0 ceph01, quorum 0,1,2 ceph01,ceph03,ceph02或者
[root@ceph01 ~]# ceph mon dump
dumped monmap epoch 3

1: [v2:192.168.11.103:3300/0,v1:192.168.11.103:6789/0] mon.ceph03
2: [v2:192.168.11.102:3300/0,v1:192.168.11.102:6789/0] mon.ceph02要检查监视器的法定人数状态，执行下面的命令：
ceph quorum_status -f json-prettyCeph 会返回法定人数状态，例如，包含 3 个监视器的 Ceph 集群可能返回下面的：
[root@ceph01 ~]# ceph quorum_status -f json-pretty
