We have the following config for replica set.
ecset01:PRIMARY> cfg = rs.conf()
{
"_id" : "ecset01",
"version" : 25,
"members" : [
{
"_id" : 1,
"host" : "10.98.2.21:27017",
"priority" : 2
},
{
"_id" : 2,
"host" : "10.98.2.22:27017",
"priority" : 3
},
{
"_id" : 3,
"host" : "10.98.2.20:27017",
"priority" : 4
},
{
"_id" : 4,
"host" : "10.98.141.170:27017",
"priority" : 0,
"hidden" : true
},
{
"_id" : 5,
"host" : "10.98.141.120:27017",
"priority" : 0,
"slaveDelay" : 86400,
"hidden" : true
},
{
"_id" : 6,
"host" : "10.10.14.158:27017",
"priority" : 0,
"slaveDelay" : 86400,
"hidden" : true
}
]
}
we try to reset slaveDelay from 86400 to 0 .
cfg = rs.conf()
cfg.members[5].slaveDelay = 0
rs.reconfig(cfg)

We are able to make Primary after shutting down "host" : "10.10.14.158:27017". We like to know why MongoDB behaves like this.
