Deployment With Ceph
====================
This script will create two loopback devices for ceph as one disk for OSD data and other disk for
block DB and block WAL.
If loop0 and loop1 devices are busy in your case , feel free to change them in
parameters.
.. note::
For other deployment options, select appropriate ``Deployment with ...``
option from `Index <../developer/index.html>`__ page.
@ -17,7 +22,7 @@ Alternatively, this step can be performed by running the script directly:
.. code-block:: shell
./tools/deployment/developer/ceph/040-ceph.sh
./tools/deployment/developer/ceph/040-ceph.sh /dev/loop0 /dev/loop1
Activate the OpenStack namespace to be able to use Ceph

Create two loopback devices for ceph as one disk for OSD data and other disk for
block DB and block WAL.
If loop0 and loop1 devices are busy in your case , feel free to change them in parameters
by using --ceph-osd-data and --ceph-osd-dbwal options.
