Functions

func GetValidVolumeSources

func GetValidVolumeSources(clientset kubernetes.Interface, namespace string, volumeSources []rookalpha.VolumeSource) (validVolumes []rookalpha.VolumeSource, err error)

GetValidVolumeSources returns all volumes that has an OSDDeployment

func IsRemovingNode

func IsRemovingNode(devices string) bool

Types

type Cluster

type Cluster struct {
	Namespace string

	Keyring string

	DesiredStorage rookalpha.StorageScopeSpec // user-defined storage scope spec
	ValidStorage   rookalpha.StorageScopeSpec // valid subset of `Storage`, computed at runtime

	Network cephv1.NetworkSpec
	// contains filtered or unexported fields
}

Cluster keeps track of the OSDs

func New

func New(
	clusterInfo *cephconfig.ClusterInfo,
	context *clusterd.Context,
	namespace string,
	rookVersion string,
	cephVersion cephv1.CephVersionSpec,
	storageSpec rookalpha.StorageScopeSpec,
	dataDirHostPath string,
	placement rookalpha.Placement,
	annotations rookalpha.Annotations,
	network cephv1.NetworkSpec,
	resources v1.ResourceRequirements,
	ownerRef metav1.OwnerReference,
	isUpgrade bool,
	skipUpgradeChecks bool,
) *Cluster

New creates an instance of the OSD manager

func (*Cluster) Start

func (c *Cluster) Start() error

Start the osd management

type Monitor

type Monitor struct {
	// contains filtered or unexported fields
}

Monitor defines OSD process monitoring

func NewMonitor

func NewMonitor(context *clusterd.Context, clusterName string) *Monitor

NewMonitor instantiates OSD monitoring

func (*Monitor) Start

func (m *Monitor) Start(stopCh chan struct{})

Start runs monitoring logic for osds status at set intervals

type OSDInfo

	DevicePartUUID      string `json:"device-part-uuid"`
	CephVolumeInitiated bool   `json:"ceph-volume-initiated"`
	//LVPath is the logical Volume path for an OSD created by Ceph-volume with format '/dev/<Volume Group>/<Logical Volume>'
	LVPath string `json:"lv-path"`
}

type OrchestrationStatus

type OrchestrationStatus struct {
	OSDs         []OSDInfo `json:"osds"`
	Status       string    `json:"status"`
	PvcBackedOSD bool      `json:"pvc-backed-osd"`
	Message      string    `json:"message"`
