Check that you've set the _revs_limit for the db, otherwise compaction
will retain more versions than you need.

Something like:
% curl -X PUT -d '1' 'localhost:5984/chef/_revs_limit'

Sets it to 1, which is fine for chef.

Subject:  [chef] Re: disk running out of space


Hi Ranjib,

I may have had 20 version bumps ever. I only just recently started
versioning as I needed to keep separate versions for prod and staging
environments.

I can't imagine version bumps causing 40GB+ of disk usage, though. I may
have uploaded my cookbooks a few thousand times, but I've only made 2 or 3
changes in the last month.

could there be something else?

Do you bump up the cookbook versions too often? Check if you have older

Hi

I've been running chef-server since about March of this year on our
infrastructure for 81 nodes. After running out of space twice due to
couchDB compaction being incorrectly configured, I finally got it working
right, but I'm still beginning to run out of space
 at a rate of around 1.5GB per week.

I began poking around in the couchDB web UI and we've got over 11,000
documents stored in the 'chef' database taking up 42GB. Looking at the
docs, they're mostly 'sandbox' objects from what I can tell, with the
occasional 'data_bag' object. Also, the vast majority
 of the sandbox objects I've looked at have a 'create_time' of march or
april of this year.

So my questions are:

1. is there any way to clean up these old documents
2. is there any way to prevent couchdb from getting larger? I have a 60GB
disk allocated exclusively for couchdb data and that's a lot larger than
I'd really like
3. could it be something else that's misconfigured?

Some details about the installation:

The server is Ubuntu and chef-server was installed via the OpsCode PPA.
We're running chef 0.10.8.

I've got a couple of recipes that set node attributes when they run;
primarily datestamps for when some recipes are run so they don't get run
on a regular basis and things like that, but I'm not aware of anything
else I could be doing that would cause such
 growth in the database.

Hopefully you guys can shed some light on this.

Thanks!
