Functions

func AddDesiredDevice

func AddDesiredDevice(etcdClient etcd.KeysAPI, device, nodeID string) error

add a device to the desired state

func AddDesiredDir

func AddDesiredDir(etcdClient etcd.KeysAPI, dir, nodeID string) error

add a device to the desired state

func GetAppliedOSDs

func GetAppliedOSDs(nodeID string, etcdClient etcd.KeysAPI) (map[int]string, error)

For all applied OSDs, gets a mapping of their osd IDs to their device uuid

func GetCrushMap

func GetCrushMap(adminConn client.Connection) (string, error)

calls osd getcrushmap

func NewAgent

func NewAgent(factory client.ConnectionFactory, devices string, forceFormat bool, location string) *osdAgent

func RemoveDesiredDevice

func RemoveDesiredDevice(etcdClient etcd.KeysAPI, device, nodeID string) error

remove a device from the desired state

Types

type Device

type Device struct {
	Name   string `json:"name"`
	NodeID string `json:"nodeId"`
	Dir    bool   `json:"bool"`
}

type Leader

type Leader struct {
}

func NewLeader
