Disk running out of space

Chef Infra (archive)
1

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!

Do you bump up the cookbook versions too often? Check if you have older
versions of cookbooks thst you dont use,

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?

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.

Hi Mark,

I did that and ran my compaction script again...

in the couchdb web UI, the size of the DB went from 41.9GB to 41.3GB and doesn't seem to be getting smaller. Additionally I did:

$ curl localhost:5984/chef
{"db_name":"chef","doc_count":11178,"doc_del_count":204,"update_seq":497447,"purge_seq":0,"compact_running":false,"disk_size":44302975077,"instance_start_time":"1353113098236259","disk_format_version":5,"committed_update_seq":497447}

and it says it's does not have a compact_running.

Is there anything else I can do?

Is there any chance that this will reduce the amount of space used on-disk? I know some database systems will keep the space on-disk requisitioned, but I'm not super experienced with couchdb.

Thanks.

It's been awhile since I looked at this but here's my couchdb compact
recipe. It's similar in functionality to yours except for the last 5 lines:

http_request "cleanup chef couchDB" do
action :post

end

Full recipe: 4092905’s gists · GitHub

I've added that line to my script and run it, but it doesn't appear to have done anything.

I'll keep an eye on my disk usage and see if that stifles the growth. I've got around 20GB free on the partition, so I should be safe for the next week while I observe.

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!

I've run into this as well and came up with the same script. I've ended up resorting to nightly restarts to keep the disk usage in line.
Without the restarts the view files stick around, sounds like that's what's happen here

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

changes in the last month.

I'd run into a similar problem with the size of couchdb bloating up to a
few GB. Performing regular compaction as part of a chef recipe that
performs maintenance has eased the problem, and we're now down to a few
hundred megs at max.

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?

Hi

I've been running chef-server since about March of this year on our

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

  1. 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!

Yeah, I've got something similar set up:

Hi there,

Cleaning up CouchDB actually requires 3 different compaction commands, but
some of the responses in this thread don't mention all 3:
View Compaction, View Cleanup, and overall Compaction. Without running all
3, not much space will be cleared.

I've written a small python command line tool that aides me in running
these commands by automatically seeking all the views and running the
compaction commands against them. Additionally, you can dump a GZ backup of
your database as well.

I hope this helps: GitHub - bmhatfield/couch-compaction: A simple script to automatically perform the various CouchDB compaction tasks.

Ah, that looks correct enough to me.

Apologies if I've also missed this, but what version of Couch are you
running?

If it's not 1.2, I strongly recommend you upgrade; that may help ensure
that the compaction and cleanup tasks actually work. I noticed a huge
improvement in compaction and such under 1.2 vs. previous versions myself.
