Overview

Package osd for the Ceph OSDs.

Package osd for the Ceph OSDs.

Package osd for the Ceph OSDs.

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.

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

func (m *Monitor) Update(removeOSDsIfOUTAndSafeToRemove bool)

Update updates the removeOSDsIfOUTAndSafeToRemove

	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"`
}
