Closing question in mongo db

When I do sharding then after getting an error when using addShard function in mongodb: Please help me

"ok" : 0,
"errmsg" : "no such command: addShard",
"code" : 59,
"bad cmd" : {
    "addShard" : "<server name>"
}

Why is this error occurring?

It looks like you might not be related to the mongos instance.

Make sure you are connected to mongo (router). Here is some sample code that I am using to implement sharding with reference to addShard. I've included the rest of the code for clarity.



//this adds members of a replica set as a shard
sh.addShard("rs0/serverShd4:27017,serverShd4b:27017,serverShd4c:27017")

//indexes
use mydb
db.mycoll.ensureIndex({s:"hashed"})

//The db name is "mydb"
sh.enableSharding("mydb")

//This is the shard key strategy deemed necessary by OI to date
sh.shardCollection( "mydb.mycoll", { s: "hashed" } )

switched to db admin

db.runCommand ({addshard: "localhost: 10000"})

{"shardadded": "shard0000", "ok": 1}



db.runCommand ({addshard: "localhost: 10001"})

{"shardadded": "shard0001", "ok": 1}

must work. http://comments.gmane.org/gmane.comp.db.mongodb.user/77102
