   * `onlyApplyOSDPlacement`: Whether the placement specific for OSDs is merged with the `all` placement. If `false`, the OSD placement will be merged with the `all` placement. If true, the `OSD placement will be applied` and the `all` placement will be ignored. The placement for OSDs is computed from several different places depending on the type of OSD:
     - For non-PVCs: `placement.all` and `placement.osd`
     - For PVCs: `placement.all` and inside the storageClassDeviceSet from the `placement` or `preparePlacement`
+* `disruptionManagement`: The section for configuring management of daemon disruptions
   * `managePodBudgets`: if `true`, the operator will create and manage PodDisruptionBudgets for OSD, Mon, RGW, and MDS daemons. OSD PDBs are managed dynamically via the strategy outlined in the [design](https://github.com/rook/rook/blob/master/design/ceph/ceph-managed-disruptionbudgets.md). The operator will block eviction of OSDs by default and unblock them safely when drains are detected.
   * `osdMaintenanceTimeout`: is a duration in minutes that determines how long an entire failureDomain like `region/zone/host` will be held in `noout` (in addition to the default DOWN/OUT interval) when it is draining. This is only relevant when  `managePodBudgets` is `true`. The default value is `30` minutes.
   * `manageMachineDisruptionBudgets`: if `true`, the operator will create and manage MachineDisruptionBudgets to ensure OSDs are only fenced when the cluster is healthy. Only available on OpenShift.
