Cannot start MongoDB

[Mange]

Hi,

I realize most of the information here is useless for debugging. Help me collect information for you. I cannot figure out how to debug this further.

I installed the prefpane and could not start the instance. I started the Lingon program to edit my launchctl files and noticed that it had not migrated my plist since I wasn't using the one that comes with Homebrew. It's exactly the same commandline and all, I just modified the name.

Here's the commandline:

/usr/local/bin/mongod run --config /usr/local/etc/mongod.conf

So I tried editing the one that was created by the prefpane to use the same commandline. That didn't work.

I then removed all plists about MongoDB, loaded the ones from the Homebrew install like the instructions and then started the prefpane again. The plist was now migrated. Still no go.

I try starting from the commandline using launctl start com.remysaissy.mongodbprefspane, but the server does not come up. The logs are not touched.

I've unloaded, loaded, started, stopped, changed, etc. until my head hurts. I cannot understand why it's not starting up. Starting up manually using the same commandline as in the plist works normally.

I re-added the homebrew plist and it works like it should. Here's the diff (ignoring whitespace with -w):

No real differences there. It must be something with the prefpane, or something. I don't get it.

Hi Mange, do you know if the migrated plist has started (or at least tried to) with the UserName mange?

[Mange]

Is there a good way to test this? Changing the command to whoami > /tmp/test?

[remysaissy]

Sorry, I didn't see your message before. yes, whoami would do the job. Replace mongod by whoami in the launchd plist.

I changed the command to bash -c "whoami > /tmp/test" and it contains mange.
