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.
