-The following parameters must be used to configure the storage driver
-(case-sensitive):
-
-* `poolname`: Name of the Ceph pool
-* `username` *optional*: The user to connect as (i.e. admin, not client.admin)
-* `chunksize` *optional*: Size of the written RADOS objects. Default value is
-4MB (4194304).

-This drivers loads the [Ceph client configuration][rados-config] from the
-following regular paths (the first found is used):
-
-* `$CEPH_CONF` (environment variable)
-* `/etc/ceph/ceph.conf`
-* `~/.ceph/config`
-* `ceph.conf` (in the current working directory)
