# Major Themes
|
|
|
|
## Action Required
|
|
|
|
## Notable Features
|
|
- Creation of storage pools through the custom resource definitions (CRDs) now allows users to optionally specify `deviceClass` property to enable
|
|
distribution of the data only across the specified device class. See [Ceph Block Pool CRD](Documentation/ceph-pool-crd.md#ceph-block-pool-crd) for
|
|
an example usage
|
|
- Added K8s 1.15 to the test matrix and removed K8s 1.10 from the test matrix.
|
|
- OwnerReferences are created with the fully qualified `apiVersion` such that the references will work properly on OpenShift.
|
|
- Linear disk device can now be used for Ceph OSDs.
|
|
|
|
### Ceph
|
|
|
|
- Rook can now be configured to read "region" and "zone" labels on Kubernetes nodes and use that information as part of the CRUSH location for the OSDs.
|
|
- Rgw pods have liveness probe enabled
|
|
- Rgw is now configured with the Beast backend as of the Nautilus release
|
|
- OSD: newly updated cluster from 0.9 to 1.0.3 and thus Ceph Nautilus will have their OSDs allowing new features for Nautilus
|
|
- Rgw instances have their own key and thus are properly reflected in the Ceph status
|
|
- The Rook Agent pods are now started when the CephCluster is created rather than immediately when the operator is started.
|
|
- Ceph CRUSH tunable are not enforced to "firefly" anymore, Ceph picks the right tunable for its own version, to read more about tunable [see the Ceph documentation](http://docs.ceph.com/docs/master/rados/operations/crush-map/#tunables)
|
|
- `NodeAffinity` can be applied to `rook-ceph-agent DaemonSet` with `AGENT_NODE_AFFINITY` environment variable.
|
|
- `NodeAffinity` can be applied to `rook-discover DaemonSet` with `DISCOVER_AGENT_NODE_AFFINITY` environment variable.
|
|
- Rook does not create an initial CRUSH map anymore and let Ceph do it normally
|
|
|

## Deprecations

|
|
|
### Ceph
|
|
|
|
- For rgw, when deploying an object store with `object.yaml`, using `allNodes` is not supported anymore, a transition path has been implemented in the code though.
|
|
So if you were using `allNodes: true`, Rook will replace each daemonset with a deployment (one for one replacement) gradually.
|
|
This operation will be triggered on an update or when a new version of the operator is deployed.
|
|
Once complete, it is expected that you edit your object CR with `kubectl -n rook-ceph edit cephobjectstore.ceph.rook.io/my-store` and set `allNodes: false` and `instances` with the current number of rgw instances.
