待ちましょうｗ
終わったかどうかは以下のような方法で確認できます。
$ mongo
$ rs.status()

SecondaryのInitial Sync
Tutorialを見ると、以下の様なことを行えば良いようです。
a. Stop the member’s mongod instance. To ensure a clean shutdown, use the db.shutdownServer() method from the mongo shell or on Linux systems, the mongod --shutdown option.
b. Delete all data and sub-directories from the member’s data directory. By removing the data dbPath, MongoDB will perform a complete resync. Consider making a backup first.
1. 正規方法でMongoを止める。
2. データディレクトリを削除する。
そして起動すればいいんですね。
やってみましょう。
repltry:SECONDARY> use admin
switched to db admin
repltry:SECONDARY> db.shutdownServer()

ちゃんと死んでますね。
ではデータを消しましょう。
データの場所は /etc/mongod.conf のdbpathに記述されています。
$cat /etc/mongod.conf
logpath=/var/log/mongodb/mongod.log
logappend=true
fork=true
dbpath=/var/lib/mongo
pidfilepath=/var/run/mongodb/mongod.pid
$ sudo rm -rf * /var/lib/mongo/*
これでおｋかと。
では起動しましょう。
$ sudo service mongod start
$ mongo
repltry:STARTUP2>
STARTUP2となっていますね。
これでinitial syncが始まります。
Primaryの方で見てみると
repltry:PRIMARY> rs.status()
{

}
],
"ok" : 1

のようになっていました。
結構さくっと終わっちゃったので、早めにrs.status()を実行しないと見れません。
こんな感じでInitial Syncが出来るようです。
また色々と試してみようかなと思います。
