From 6faca15437bf0c8b88aa424b4bc9e3a0b870e863 Mon Sep 17 00:00:00 2001 From: Giulio Fidente Date: Thu, 21 Sep 2017 21:18:01 +0200 Subject: Default Ceph pg_num and pgp_num to 128 As per Ceph docs [1] we should default pg_num and pgp_num to 128 when using less than 5 OSDs. This same change was applied to the ceph-ansible profiles with [2]. Also updates the CI environment files to continue using 32 where we deploy a single OSD. 1. http://docs.ceph.com/docs/master/rados/operations/placement-groups/ 2.
