[chef] Re: Mongodb replicaset failure: Could not connect to database: 'localhost:27017'

[Liam Kirsher < >]

I ended up adding some code to the library that sleeps until the connection is established and that does the trick.
I'll see if I can contribute it back to the authors.

" type="cite"> Hi,

I'm having a little issue with getting mongo replicasets working.
Partly, I'm needing a little more understanding of Chef's execution order -- what happens when, notifies, etc..
The problem is that the replicaset is never initiated, although the parameters look correct.  The apparent reason is that when Chef tries to access the database it is not running.
However, the database is running and accessible at localhost:27017 at the end of the run.

I thought the issue might be related to this:
https://github.com/mongodb/mongo/commit/695c026fa64677f7661e940fe26a116041fed479
so I added that to the mongo cookbook I'm using. https://github.com/LiamK/Ops/tree/master/chef/cookbooks/mongodb
(That's my fork of the Ops version, but the only thing I changed was to disable upstart and use the standard init.d script.)
Unfortunately, that didn't help.

So, at this point I'm just looking for a good place to "sleep" to give the mongo process time to restart, so it's running when the replicaset config command runs.
Or, better, to sleep & test to see if it's running and accepting connections.  Should I just put that in the config_replicaset ruby_block?

Thanks,
Liam
