Can't drop collection from SyncClusterConnection ??

[Mark Hansen]

I'm getting "write $cmd not supported" when trying to drop a collection.

We've got a replica set with 3 boxes.  I open a shell connection like this:

mongo host1,host2,host3/?replicaSet=fooset

All is good and I'm in the mongo shell like this:

fooset:PRIMARY>

However, when I try to drop a collection that I've been using as temporary storage, I get this:

fooset:PRIMARY> db.tmpOut.drop();

What version of Mongo are you using?

2.2.0

Hi Mark,

I was able to reproduce your issue but found the behaviour when adding "/?replicaSet=fooset" was not the correct behaviour.

You should be able to connect just with: mongo host1,host2,host3

You should be aware that this does not give you full connection pool functionality and the shell will not automatically try to connect to the current primary.

The mongo shell is designed to be a 1:1 interface.

Where did you get the /?replicaSet=fooset syntax?

Cheers,

David
