Description jomurphy 2017-09-06 18:00:38 UTC

+++ This bug was initially created as a clone of Bug #1481821 +++

Description of problem:
OSP director defaults set Ceph's pg_num and pgp_num to 32 which is too low. This will cause performance issues for any costumer that will use it.

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


How reproducible:
100%

Steps to Reproduce:
1.
2.
3.

Actual results:
The pg_num and pgp_num for all the pools is 32

Expected results:
pg_num and pgp_num default should be 128, which is the right number for the minimum deployment of 3 OSDs in a cluster

Additional info:

--- Additional comment from Jeff Brown on 2017-08-29 14:11:34 EDT ---

We need to set this to 128 by default. It will potentially overwritten by derived parameters or customers that  read the documentation.

Comment 3 Yogev Rabl 2017-11-06 15:30:40 UTC

The defaults placement groups number is 128
