"Unkown Error" when connecting to secondary server in replica set.

[codazoda]

I'm running 6 Mongo servers. Only one of those is the primary (which changes from time to time). I'm able to connect to the primary server using Genghis, but I'm not able to connect to any of the secondary servers. When I do, I get an "Unknown Error" at the top and a waiting indicator that never finishes.

Do you mind checking your JavaScript console or Network tab and looking for errors for me?

[codazoda]

In the Javascript console I have the following:

GET http://dropbox.dev/ksl/genghis/genghis.php/servers/mongodb-rs1.ksl.com/databases 500 (Internal Server Error)
Uncaught Error: A "url" property or function must be specified

Here's the response from the network tab, which you might find useful. In particular, the "500: not master and slaveOk=false" error. According to the interwebs, this is the same error I would get if I tried to read from a slave if I hadn't run rs.slaveOk() in a console (which prevents you from accidentally treating "eventually consistent" data as if it were current). Maybe that could be added as a command you initially send to mongo on connection.

Genghis

500: not master and slaveOk=false

If you think you've reached this message in error, please press 0 to speak with an operator. Otherwise, hang up and try again.

Gotcha. Just add ?slaveOk=true to the end of your server URI, and you should be good.

[codazoda]

Not sure where to put it. I tried adding ?slaveOk=true to the end of the server config and I get this.

Then I tried adding it, manually, to the URL after clicking that link and I get this.

[bobthecow]

Yeah, that should have worked :-/

[theartoflogic]

I have v2.3.8 and I tried adding ?slaveOk=true but I get an error: "Unsupported connection option - slaveOk"

In the (PHP) code I see a switch statement that explicitly calls out "slaveOk" in one of the cases that throws the "Unsupported connection option..." exception. Is connecting to a slave now explicitly disabled?

[bobthecow]

You're absolutely right. I'd forgotten that slaveOk support was dropped because Genghis doesn't have a read-only mode.

+1. I also have this "Error: A "url" property or function must be specified", even when I select the primary server.
Just updated to the 2.6.1 version of mongodb, any coincidence ? Thx

I have something similar but before this error, I have another one:

500: PHP error:  Genghis_Json::doEncode(): The 'sec' property is read-only

[bobthecow]

@shordeaux Yours is definitely an error, but is completely unrelated :)
