Now, we can schedule snapshots on pools from the CephBlockPool CR when
the pool is mirrored.
It can be enabled like this:
```
mirroring:
enabled: true
mode: pool
snapshotSchedules:
- interval: 24h # daily snapshots
startTime: 14:00:00-05:00
```
Multiple schedules are supported since snapshotSchedules is a list.

## Breaking Changes
|
|
|
|
### Ceph
|
|
|
|
- Ceph mons require an odd number for a healthy quorum. An even number of mons is now disallowed.
|
|
- Update deprecated CRD apiextensions.k8s.io/v1beta1 to v1 ([#6424](https://github.com/rook/rook/pull/6424))
|
|
- preservePoolsOnDelete is deprecated for CephFilesystem and is no longer allowed because of data-loss concerns. preserveFilesystemOnDelete acts as a replacement and preserves the filesystem when the CephFilesystem CRD is deleted (which implicitly includes all associated pools). See [#6495](https://github.com/rook/rook/pull/6495) for more details.
|
|
- The discovery daemon is disabled by default since the discovery is not necessary in most clusters. Enable the discovery daemon if
|
|
devices are being added to nodes and you want to automatically configure OSDs on new devices without restarting the operator.
|
|
- The CRDs have been separated from common.yaml into crds.yaml to give more flexibility for upgrades.
