Error connect to external ceph cluster

[BN]

Hello,

**Bug Report**

What happened: Configured ceph cluster using ceph-ansible. Deployed openstack, once I am trying to add an image, getting an error.

What you expected to happen: Image shall be added.

How to reproduce it (minimal and precise): Following this guide https://docs.openstack.org/kolla-ansible/latest/reference/storage/external-ceph-guide.html

**Environment**:
* OS (e.g. from /etc/os-release): Ubuntu 18.04
* Kernel (e.g. `uname -a`): 4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
* Docker version if applicable (e.g. `docker version`): 19.03.4
* Kolla-Ansible version (e.g. `git head or tag or stable branch` or pip package version if using release):
* Docker image Install type (source/binary): source
* Docker image distribution: ubuntu
* Are you using official images from Docker Hub or self built? official
* If self built - Kolla version and environment used to build:
* Share your inventory file, globals.yml and other configuration files if relevant

Ceph:

Pools and clients were created using that doc https://docs.ceph.com/docs/master/rbd/rbd-openstack/ ;
I added keyrings and ceph.conf in /etc/kolla/config folder; I could not assign chown to those since those accounts are not associated with the host machine and shall be working inside container therefore, rbd_user=glance,cinder,nova should be working.

ceph osd lspools:

1 volumes
2 images
3 backups
4 vms
5 .rgw.root
6 default.rgw.control
7 default.rgw.meta
8 default.rgw.log

I would really appreciate if you can suggest any debugging steps so I can fix that issue. Thank you

The problem is in ceph.conf:
mon host = [v2:10.0.1.1:3300,v1:10.0.1.1:6789]

Ceph client components (as deployed with kolla) do not yet understand the new syntax. Please use the old, compatible one:
mon host = 10.0.1.1
