I have a DB that is currently single-server and I'm trying to move it to a replica set. Currently everything is on app.checkin.to and I want to add s1db1.checkin.to and s1db2.checkin.to. All servers are running 1.6.2 and the two new server are blank. The --replSet parameter is checkinto.
From app.checkin.to I do:
config = {
"_id" : "checkinto",
"members" : [
{
"_id" : 0,
"host" : "app.checkin.to"
},
{
"_id" : 1,
"host" : "s1db1.checkin.to"
},
{
"_id" : 2,
"host" : "s1db2.checkin.to"
}
]
}
> rs.initiate(config);
{
"info" : "Config now saved locally. Should come online in about a minute.",
"ok" : 1
}
> rs.status()
{
"set" : "checkinto",
"date" : "Mon Sep 06 2010 17:50:09 GMT-0700 (PDT)",
"myState" : 5,
"members" : [
{
"_id" : 0,
"name" : "fs:27017",
"health" : 1,
"state" : 5,
"self" : true
},
{
"_id" : 1,
"name" : "s1db1.checkin.to",
"health" : 0,
"state" : 6,
"uptime" : 0,
"lastHeartbeat" : "Mon Sep 06 2010 17:50:07 GMT-0700 (PDT)",
"errmsg" : "still initializing"
},
{
"_id" : 2,
"name" : "s1db2.checkin.to",
"health" : 0,
"state" : 6,
"uptime" : 0,
"lastHeartbeat" : "Mon Sep 06 2010 17:50:07 GMT-0700 (PDT)",
"errmsg" : "still initializing"
}
],
"ok" : 1
}
> db.isMaster()
{
"setName" : "checkinto",
"ismaster" : false,
"secondary" : false,
"hosts" : [
],
"ok" : 1
}

It seems like the operative error is that s1db1 and s1db2 can't find themselves in the config.
replSet warning can't find self in the repl set configuration
Are those machines using the default port? Do their hostnames match the names you've provided?

Ah, yes the hostnames were the issue.
Thanks.
