Question

When initializing MongoDB replica sets on Azure dev i get following error:

Command ‘replSetInitiate’ failed: local.oplog.rs is not empty on the initiating member. cannot initiate. (response: { “errmsg” : “local.oplog.rs is not empty on the initiating member. cannot initiate.”, “ok” : 0.0 })

I have tried cleanup localstorage on recycle, but it does not help.

I used source that provided by 10gen: source code and blog post

UPDATE:

That error appear in console after calling RunInitializeCommandLocally method (happens for each ReplicaSetRole)

Then i try to create MongoServer and each instance in it has Disconnected state.

Answer 1

There was no problem at all. This exception is normal behavior. Just need to wait couple of seconds and replica set will be initialized.

Note: use mongo.exe to check status of replica set.
