ReplicaSetId conflict while adding node MongoDB

余生长醉 提交于 2019-12-06 14:49:41
When I try to add a new node to my replicate set I get this message: { "ok" : 0, "errmsg" : "Our replica set ID of 5890ad86c92c6c88e8573df0 did not match that of 10.0.253.3:27017, which is 5890a6b137e1380d1e697f2a", "code" : 103, "codeName" : "NewReplicaSetConfigurationIncompatible" } I had the same error and impossible to find out why ... I come back on the post to send the solution if others pass here. Simply do not initialize the replicate on both servers: I have two separate X and Y servers without mongodb, X and Y are IP addresses or domains. Install mongodb on both servers Edit the sudo

MongoDB Replica Set Member State is “OTHER”

烂漫一生 提交于 2019-12-06 02:26:12
问题 Three members, primary & secondary - and a third one that's "OTHER" - I can't find any info on that state, not sure what to do, I've restarted the instance, but it always comes-up the same. Can find no documentation on that state. I'm new to replica sets - and any help would be appreciated. 回答1: The config is not set correctly. You can use following command to init: rs.initiate({ _id: "rs0", version: 1, members: [ { _id: 0, host : "localhost:27017" } ] } ) If you have already initiated, you

MongoDB Multiple Masters in ReplicaSet

三世轮回 提交于 2019-12-06 01:42:41
问题 I've got a question concerning multiple masters in a replicaSet with MongoDB. I have the following layout: Server A --> with MongoDB & several applications Server B --> with MongoDB & several applications Both instances of MongoDB are organised in the same replica Set (Server A as Primary, Server B as Secondary). But now there is the problem. Both databases should contain data from the applications on the server. Is it possible to deploy a replica Set with two masters so that the data from

pymongo: Advantage of using MongoReplicaSetClient?

问题 It seems that both MongoClient and MongoReplicaSetClient can connect to mongo replica sets. In fact, their documentation pages are nearly identical - same options, same methods, etc - except that the latter's constructor requires me to specify a replicaSet. In both cases, we may specify a read preference. In both cases, we must handle the AutoReconnect exception if a stepdown occurs. So my questions are: Why would one use one versus the other, since one can perform the exact same operations

MongoDB ReplicaSet - PRIMARY role falls to SECONDARY when only PRIMARY is left

☆樱花仙子☆ 提交于 2019-12-03 20:20:56
问题 I am investigating using MongoDB ReplicaSet for high availability. But just discovered that in ReplicaSet with 3 nodes, if PRIMARY mongod is the only one left (that is 2 other mongod instances died or were shut down), then after several seconds it switches role to SECONDARY and accepts writes no more. That makes Replica Set worth less than single instance. I know & understand about PRIMARY election, but the PRIMARY role is fixed to a server (by using priority set to ,say, 10) and (for example

MongoDB replica set with simple password authentication

北战南征 提交于 2019-12-03 18:49:59
问题 I have a MongoDB replica set of 3 servers (1 primary, 1 secondary, 1 arbiter; this is the default replica set created by Google Cloud 1-click install). The 2 config files (mongod.conf) of primary server and secondary server have been changed with "security.authorization: enabled" added. Root user is added with the following MongoDB shell command: use admin db.createUser({user:"root",pwd:"root",roles:["root"]}) After restarting MongoDB services on the primary and secondary servers with "sudo

What is the difference between ReplicaSet and ReplicationController?

二次信任 提交于 2019-12-03 14:29:06
问题 From what I can tell in the documentation, a ReplicaSet is created when running a Deployment. It seems to support some of the same features of a ReplicationController - scale up/down and auto restart, but it's not clear if it supports rolling upgrades or autoscale. The v1.1.8 user guide shows how to create a deployment in Deploying Applications (which automatically creates a ReplicaSet ), yet the kubectl get replicasets command is not available until v1.2.0. I cannot find any other

“This node was not started with the replSet option”

北城余情 提交于 2019-12-02 02:53:56
问题 I am studying the MongoDBUniversity's M101P: MongoDB for Developers course. I am using WiredTiger on MongoDB 3.2 . I am currently on the topic of replica sets . The course requires I create a replica set using the following code: mongod --replSet rs1 --logpath "1.log" --dbpath /data/rs1 --port 27017 --fork But I am using Windows, which doesn't support fork , so using this gist (as recommended by a course admin) I ran these lines simultaneously in 3 different consoles after I had created the
