Description of problem:

This is a hyperconverged deployment rhosp11 upgraded to 12 then 13(august), and now to 13 latest.

When trying to update to the latest version we got the following error:

2019-04-07 13:03:58,839 p=29384 u=mistral |  failed: [192.168.24.10] (item=[u'/etc/ceph/ceph.mon.keyring', {'_ansible_parsed': True, u'stat': {u'exists': False}, '_ansible_item_result': True, '_ansible_no_log':

but if we look a few hours before the file was there:
