Description Alex Krzos 2017-01-13 18:39:01 UTC

Description of problem:
Swift deployed by tripleo using OSPd deploys single swift-object-server, swift-container-server, and swift-account-server processes which can/will affect the scalability and performance of your Swift.  General Swift tuning guide recommends a one to one ratio of physical cpu to process counts for these processes with a single concurrency for the background tasks with ther exception of the replicators [0]

Version-Release number of selected component (if applicable):
OSP10

How reproducible:
Always

Steps to Reproduce:
1. Deploy overcloud and review process counts of the swift services
2.
3.

Actual results:


Expected results:

Comment 1 Paul Grist 2017-04-06 02:22:20 UTC

This may be covered by some WIP and doc changes coming, over to Swift to comment/triage.

Comment 2 Christian Schwede (cschwede) 2017-08-25 10:33:26 UTC

It's possible to set the workers count using a template with the proposed patch for puppet-swift applied like this:

parameter_defaults:
  ControllerExtraConfig:
    swift::storage::all::account_server_workers: 3
    swift::storage::all::container_server_workers: 5
    swift::storage::all::object_server_workers: 7

Comment 3 Christian Schwede (cschwede) 2017-08-25 11:43:07 UTC

Also proposed a t-h-t patch to simplify this:

parameter_defaults:
  SwiftAccountWorkers: 3
  SwiftContainerWorkers: 5
  SwiftObjectWorkers: 7

Comment 4 Christian Schwede (cschwede) 2017-09-21 15:35:51 UTC

Merged after release - moving to 13.

Comment 10 Tzach Shefi 2018-02-26 07:23:14 UTC

Still waiting on newer puddle
Last one I managed to deploy today, none sufficient yet > 2018-02-14.1
