Mongo DB issues with replSet
mongodb
Solution
One reason that I can think of is that you already had a mongod running on port 27017 without the `--replSet` argument before you tried starting it with. Make sure no mongod is running (`ps aux |grep mongod`) before you try this. I would also inspect the log file as it is likely that it gives a clue why it did not start in replica-set mode.
Problem
I an trying this one: mongod --replSet mySet --dbpath /data/r1 --port 27017 --oplogSize 700 mongod --replSet mySet --dbpath /data/r2 --port 27018 --oplogSize 700 mongod --replSet mySet --dbpath /data/r3 --port 27019 --oplogSize 700 then in new terminal: ``` /mongo --port 27017 MongoDB shell version: 2.0.2 connecting to: 127.0.0.1:27017/test > cfg = { _id : "mySet", members : [ { _id : 0, host : "localhost:27017" }, { _id : 1, host : "localhost:27018" }, { _id : 2, host : "localhost:27019" } ] } ``` And when I run rs.initiate(cfg) I an getting this error: { "errmsg" : "server is not running with --replSet", "ok" : 0 } Why I am getting this error? from log file: ``` Fri Jun 01 15:05:11 [initandlisten] MongoDB starting : pid=5236 port=27017 dbpath=c:\mongodb\data 64-bit host=mami Fri Jun 01 15:05:11 [initandlisten] db version v2.0.4, pdfile version 4.5 Fri Jun 01 15:05:11 [initandlisten] git version: 329f3c47fe8136c03392c8f0e548506cb21f8ebf Fri Jun 01 15:05:11 [initandlisten] build info: windows sys.getwindowsversion(major=6, minor=1, build=7601, platform=2, service_pack='Service Pack 1') BOOST_LIB_VERSION=1_42 Fri Jun 01 15:05:11 [initandlisten] options: { dbpath: "c:\mongodb\data", logappend: true, logpath: "c:\mongodb\logs\logfilename.log", service: true } Fri Jun 01 15:05:11 [initandlisten] journal dir=c:/mongodb/data/journal Fri Jun 01 15:05:11 [initandlisten] recover : no journal files present, no recovery needed Fri Jun 01 15:05:12 [initandlisten] waiting for connections on port 27017 Fri Jun 01 15:05:12 [websvr] admin web console waiting for connections on port 28017 Fri Jun 01 15:05:12 [initandlisten] connection accepted from 127.0.0.1:49663 #1 Fri Jun 01 15:05:56 [conn1] end connection 127.0.0.1:49663 Fri Jun 01 15:06:02 [initandlisten] connection accepted from 127.0.0.1:49669 #2 Fri Jun 01 15:06:11 [clientcursormon] mem (MB) res:22 virt:67 mapped:0 Fri Jun 01 15:06:19 [conn2] terminating, shutdown command received Fri Jun 01 15:06:19 dbexit: shutdown called Fri Jun 01 15:06:19 [conn2] shutdown: going to close listening sockets...
