# Ceph RADOS storage driver
|
||
|
|
|
||
|
|
An implementation of the `storagedriver.StorageDriver` interface which uses
|
||
|
|
[Ceph RADOS Object Storage][rados] for storage backend.
|
||
|
|
|
||
|
|
## Parameters
|
||
|
|
|
||
|
|
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)
|
||
|
|
|
||
|
|
