Doc Text:	.Files in `/var/lib/ceph/` are now properly removed when purging clusters The Ansible playbook for purging clusters did not properly remove files in the `/var/lib/ceph/` directory. Consequently, when trying to redeploy a containerized cluster, Ansible assumed that a cluster was already running and tried to join it because the Monitor container detected some existing files in the `/var/lib/ceph/<cluster-name>-<monitor-name>/` directory. With this update, the files in `/var/lib/ceph/` are properly removed, and redeploying a cluster works as expected.	Story Points:	---

Description Guillaume Abrioux 2018-09-27 09:52:57 UTC

Description of problem:

purge cluster playbooks don't clean /var/lib/ceph/*
It means it leaves some files in place and cause error when trying to redeploy a cluster:

Sep 26 13:18:16 mon0 docker[31316]: 2018-09-26 13:18:16.9323937f15b0d74700 -1 auth: unable to find a keyring on /etc/ceph/test.client.admin.keyring,/etc/ceph/test.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin,:(2) No such file or directory

This error occurs because ceph-container relies on the fact there is a keyring present in /var/lib/ceph/mon/<cluster>-<mon-name>/keyring to detect whether we are trying to join an existing cluster.


How reproducible:
100%

Steps to Reproduce:
1. Deploy a containerized cluster
2. Run purge-docker-cluster.yml
3. Try to redeploy a containerized cluster

Actual results:
Redeploying a cluster after purge playbook fails because of leftover.

Expected results:
We can redeploy a cluster after a purge.
