## Action Required
|
|
|
|
## Notable Features
|
|
- Added K8s 1.16 to the test matrix and removed K8s 1.11 from the test matrix.
|
|
|
|
### Ceph
|
|
|
|
- The job for detecting the Ceph version can be started with node affinity or tolerations according to the same settings in the Cluster CR as the mons.
|
|
- A new CR property `skipUpgradeChecks` has been added, which allows you force an upgrade by skipping daemon checks. Use this at **YOUR OWN RISK**, only if you know what you're doing. To understand Rook's upgrade process of Ceph, read the [upgrade doc](Documentation/ceph-upgrade.html#ceph-version-upgrades).
|
|
- Mon Quorum Disaster Recovery guide has been updated to work with the latest Rook and Ceph release.
|
|
- A new CRD property `PreservePoolsOnDelete` has been added to Filesystem(fs) and Object Store(os) resources in order to increase protection against data loss. if it is set to `true`, associated pools won't be deleted when the main resource(fs/os) is deleted. Creating again the deleted fs/os with the same name will reuse the preserved pools.
|
|
- OSDs:
|
|
- Ceph OSD's admin socket is now placed under Ceph's default system location `/run/ceph`.
|
|
- The on-host log directory for OSDs was set incorrectly to `<dataDirHostPath>/<namespace>/log`;
|
|
fix this to be `<dataDirHostPath>/log/<namespace>`, the same as other daemons.
|
|
- Use the mon configuration database for directory-based OSDs, and do not generate a config
|
|
- A new ceph-crashcollector controller has been added, that new pod will run on any node where a Ceph pod is running. Read more about this in the [doc](Documentation/ceph-cluster-crd.html#cluster-wide-resources-configuration-settings)
|
|
- PriorityClassNames can now be added to the Rook/Ceph components to influence the scheduler's pod preemption.

## Breaking Changes
|
|
|
|
### Ceph
|
|
- The `topology` setting has been removed from the CephCluster CR. To configure the OSD topology, node labels must be applied.
|
|
See the [OSD topology topic](ceph-cluster-crd.md#osd-topology). This setting only affects OSDs when they are first created, thus OSDs will not be impacted during upgrade.
|
|
The topology settings only apply to bluestore OSDs on raw devices. The topology labels are not applied to directory-based OSDs.
