Hi!

As issue #3606 is still a thing (deploying MDSs, but not creating a 
CephFS by default), I wanted to let ceph-ansible have its way and create 
a CephFS. In group_vars/all.yml I have

cephfs: data
cephfs_data: pool-fs-data
cephfs_metadata: pool-fs-metadata


The pools are created, but the playbook bails out with

failed: [cephtmds01 -> 172.17.0.35] (item=pool-fs-data) => changed=false
   cmd:
   - ceph
   - --cluster
   - ceph
   - osd
   - pool
   - application
   - enable
   - pool-fs-data
   - data
   delta: '0:00:00.561893'
   end: '2019-04-03 11:26:09.614799'
   item: pool-fs-data
   msg: non-zero return code
   rc: 1
   start: '2019-04-03 11:26:09.052906'
   stderr: 'Error EPERM: Are you SURE? Pool ''pool-fs-data'' already has 
an enabled application; pass --yes-i-really-mean-it to proceed anyway'
   stderr_lines:
   - 'Error EPERM: Are you SURE? Pool ''pool-fs-data'' already has an 
enabled application; pass --yes-i-really-mean-it to proceed anyway'
   stdout: ''
   stdout_lines: <omitted>

The pools are created, and indeed have the correct application associated:

$ ceph osd pool ls detail
pool 2 'pool-fs-data' replicated size 3 min_size 2 crush_rule 0 
object_hash rjenkins pg_num 8 pgp_num 8 autoscale_mode warn last_change 
234 flags hashpspool stripe_width 0 application cephfs
pool 3 'pool-fs-metadata' replicated size 3 min_size 2 crush_rule 0 
object_hash rjenkins pg_num 8 pgp_num 8 autoscale_mode warn last_change 
234 flags hashpspool stripe_width 0 application cephfs


This is ceph-ansible stable-4.0, deploying Nautilus on CentOS 7.

Did I miss something, or is this worth another bug report?
