This adds support for Juju's storage hooks by merging the config provided osd-devices with Juju storage provided osd-devices, in the same way that the existing Ceph charm handles them. In addition to providing support for ceph-osds via Juju storage, we provide support for multiple journal devices through Juju storage as well. We have to add a shim hook to ensure that Ceph is installed prior to storage hook invocation because storage attached at deploy time will execute hooks before the install hook Change-Id: Idad46e8f4cc32e09fbd64d29cd93745662e9f542 |

Overview
Ceph is a distributed storage and network file system designed to provide excellent performance, reliability, and scalability.
This charm deploys additional Ceph OSD storage service units and should be used in conjunction with the 'ceph' charm to scale out the amount of storage available in a Ceph cluster.
Usage
The charm also supports specification of the storage devices to use in the ceph cluster::
osd-devices:
A list of devices that the charm will attempt to detect, initialise and
activate as ceph storage.
This this can be a superset of the actual storage devices presented to
each service unit and can be changed post ceph-osd deployment using
`juju set`.
For example::
ceph-osd:
osd-devices: /dev/vdb /dev/vdc /dev/vdd /dev/vde
Boot things up by using::
juju deploy -n 3 --config ceph.yaml ceph
You can then deploy this charm by simple doing::
juju deploy -n 10 --config ceph.yaml ceph-osd
juju add-relation ceph-osd ceph
Once the ceph charm has bootstrapped the cluster, it will notify the ceph-osd charm which will scan for the configured storage devices and add them to the pool of available storage.
