Ceph » rgw

Description of problem:
Was trying to clean-up the A/A multisite configuration and noticed that the periods are still listed even after removing them and they doesn't exist.

Version-Release number of selected component (if applicable):
ceph-radosgw-10.1.1-1.el7cp.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Create an Active-Active multisite configuration using ceph 10.1.0( sync was not happening)
2. Upgraded the cluster from ceph-10.1.0 to ceph-10.1.1
3. Restarted the radosgw service
4. Tried to clean-up and re-configure the A/A multisite setup
5. Deleted periods from the list
6. list the period - all the deleted periods are still seen

Actual results:

Deleted periods are still seen

same behavior is seen on secondary zone also..

Expected results:

Clean up or un-configuration of multisite should happen gracefully
