.Cockpit installer produces incorrect values for number of buckets in `rgws.yml` Previously, using the Cockpit installer to generate the `rgws.yml` file produced incorrect values for `defaults.rgw.buckets.data:pgnum` and `rgw_override_bucket_index_max_shards`. With this release, the Cockpit installer creates correct values in `rgws.yml`.

Description Ameena Suhani S H 2020-07-09 05:28:18 UTC 
Description of problem:

The "defaults.rgw.buckets.data:pgnum: 16" is very less. It is expected to be set a considerably higher value.
Also, the "rgw_override_bucket_index_max_shards: 1" overrides the default value of the RGW system which is 11 shards which is not expected.

rgw_create_pools:
  defaults.rgw.buckets.data:
    pgnum: 16
  defaults.rgw.buckets.index:
    pgnum: 32
rgw_override_bucket_index_max_shards: 1

Version-Release number of selected component (if applicable):
cockpit-ceph-installer-1.2-0.el7cp.noarch and 
ceph-ansible-4.0.25-1.el7cp.noarch
ansible-2.8.12-1.el7ae.noarch

How reproducible:
3/3

Steps to Reproduce:
1. Use the installer to create the yml files (no need to deploy)
2. On the deploy page click save
3. review the contents of rgw.yml in /usr/share/ceph-ansible/group_vars
Comment 1 Timothy Asir 2020-08-04 05:09:26 UTC 
Shall we remove the pgnum setting to use the default value ?
Comment 3 Yaniv Kaul 2020-08-12 15:46:12 UTC 
This looks like a nice improvement, but I'd be happy if it'll be deferred to 4.2, to reduce 4.1z2 content.
Comment 13 Ameena Suhani S H 2020-11-12 02:45:28 UTC 
Verified using
cockpit-ceph-installer-1.3-0.el8cp.noarch
