[Sharding] Can't add shards.

[Nestor Ledon]

Running all instances on different machines on the same network. Only MongoS & ConfigServer are on the same machine. Shar1 & Shard2 are separate.

Everything seems to be running smooth except:

mongos> sh.addShard("192.168.2.212:27017")

{

        "ok" : 0,

        "errmsg" : "host is part of set: dunnReplSetAlpha use replica set url fo

rmat <setname>/<server1>,<server2>,...."

}

mongos>

mongos> sh.addShard("<setName>/192.168.2.212:27017")

{

        "ok" : 0,

        "errmsg" : "couldn't connect to new shard socket exception [CONNECT_ERRO

R] for <setName>/192.168.2.212:27017"

}

mongos>

Any ideas? Thank you.

Note I've also tried:

sh.addShard("<dunnReplSetAlpha>/192.168.2.212:27017")

&

sh.addShard("dunnReplSetAlpha/192.168.2.212:27017")

I'm almost positive the ports are open. These very same machines used to communicate as one ReplicaSet prior to these changes. Would not have worked unless the ports where open right? <--- Needs expert.

How does one check port on a Windows machine? I checked the Linux ReplicaSet (192.168.2.212) via telnet and it seems to be open.

Figured it out. I had a host/ip issue. Be SURE to use only hostnames or ONLY ips.

Hello

I had the same problem and i found it wad due to the firewall on my shard machine
opened the firewall and everything was fine

I have no idea what the problem that you are having is...  Can't add shards is not very specific...

Can you please start by describing what version of MongoDB you are using, what you already did and what exactly you are running that's giving an error.   Exact error as well as anything that's in the logs would be helpful as well for us to be able to help you...
