Functions

func CreateKeyring

func CreateKeyring(context *clusterd.Context, hostName, id string) (string, error)

create a keyring for the mds client with a limited set of privileges

func NewAgent

func NewAgent() *mdsAgent

func RemoveFileSystem

func RemoveFileSystem(context *clusterd.Context, fsr model.FilesystemRequest) error

Remove the given file system instance in the cluster. Multiple file systems are supported.

func Run

func Run(context *clusterd.Context, config *Config) error

Types

type Config

type Config struct {
	ID          string
	Keyring     string
	InProc      bool
	ClusterInfo *mon.ClusterInfo
}

type FileSystem

type FileSystem struct {
	ID   string `json:"id"`
	Pool string `json:"pool"`
	// contains filtered or unexported fields
}

A castle file system (an instance of CephFS)

func NewFS

func NewFS(context *clusterd.Context, id, pool string) *FileSystem

Create a new file service struct

func (*FileSystem) AddToDesiredState

func (f *FileSystem) AddToDesiredState() error

Add the file system to the desired state.

func (*FileSystem) CreateFilesystem

func (f *FileSystem) CreateFilesystem(cluster *mon.ClusterInfo) error

func (*FileSystem) DeleteFromDesiredState

func (f *FileSystem) DeleteFromDesiredState() error

Remove the file system from the desired state.

type Leader

type Leader struct {
}

func NewLeader

func NewLeader() *Leader

func (*Leader) Configure

func (r *Leader) Configure(context *clusterd.Context) error

Apply the desired state to the cluster. The context provides all the information needed to make changes to the service. Initialize CephFS. Must be idempotent.
