MonogoDB Replica Set Status Not changing from Startup to Secondary

Question

I have setup a MongoDB replica set with 3 nodes(vm's running CentOS). One node became Primary other 2 stuck in Startup. When these 2 nodes will change their states from startup to secondary.

aryabhata:PRIMARY> rs.status()
{
    "set" : "aryabhata",
    "date" : ISODate("2016-04-30T08:10:45.173Z"),
    "myState" : 1,
    "members" : [

Answer 1

From primary check whether you are able to connect to secondary

mongo --host repset1.com --port 27017

When the above one fails may be firewall or BindIP issue.

Check bind_ip (should be 0.0.0.0, change in mongodb.conf is it's 127.0.0.1):

netstat -plunt | grep :27017 | grep LISTEN

Look at the log-files of secondaries, why they are stuck. Did they receive the configuration details?

Try to reconfigure, see mongo replicaset reconfigure

Answer 2

My problem fix with set ip address for Primary instead hostname

cfg = rs.conf()
cfg.members[0].host = "public-or-private-primary-ip:27017" 
rs.reconfig(cfg)

after that secondary state change to STARTUP2
