Overview ¶

Package osd for the Ceph OSDs.

Package config provides methods for generating the Ceph config for a Ceph cluster and for producing a "ceph.conf" compatible file from the config as well as Ceph command line-compatible flags.

Functions ¶

func IsRemovingNode ¶

func IsRemovingNode(devices string) bool

func UpdateNodeStatus ¶

func UpdateNodeStatus(kv *k8sutil.ConfigMapKVStore, node string, status OrchestrationStatus) error

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,
	prepareResources 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, removeOSDsIfOUTAndSafeToRemove bool) *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

func (*Monitor) Update ¶ added in v1.1.3

func (m *Monitor) Update(removeOSDsIfOUTAndSafeToRemove bool)

Update updates the removeOSDsIfOUTAndSafeToRemove

	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"`
	SkipLVRelease bool   `json:"skip-lv-release"`
}
