func (*Controller) GetRookVersion added in v0.23.1 

func (c *Controller) GetRookVersion(ctx context.Context) (*semver.Version, error)

func (c *Controller) JSONPatchCephCluster(ctx context.Context, patches []k8s.JSONPatchOperation) (*cephv1.CephCluster, error)

JSONPatchCephCluster patches the "rook-ceph" CephCluster with the given JSON patches.

func (*Controller) MaybeRebalanceMinioServers added in v0.24.0 

func (c *Controller) MaybeRebalanceMinioServers(ctx context.Context, ns string) error

MaybeRebalanceMinioServers first, check if minio is healthy. If it is not healthy, don't do anything. (this may require manual intervention, or may be resolved when nodes come back online) Then, check for pods that have been unschedulable for more than 5 minutes and delete the underlying volume + pod. This will allow the pod to be scheduled on a node that still exists and for data to be rebalanced there. After ensuring that there are as many running replicas as possible, we can rearrange replicas to maximize the number of nodes that can be lost before losing data. To do this, first check if more than ceil(replicas/nodes) replicas exist on one node. If it does, see if we can reschedule one of those replicas safely. If such a node does not exist, instead look for nodes with less than floor(replicas/nodes) replicas, and if it exists reschedule a replica from a node with ceil(replicas/nodes).

func (*Controller) MigrateMinioData added in v0.24.0 

func (c *Controller) MigrateMinioData(ctx context.Context, utilImage string, ns string) error
