func New() resource.Driver

Types ¶

type LVDriver ¶

type LVDriver interface {
	Activate(context.Context) error
	Deactivate(context.Context) error
	IsActive(context.Context) (bool, error)
	Exists(context.Context) (bool, error)
	FQN() string
	Devices(context.Context) (device.L, error)
	DriverName() string
}

type LVDriverProvisioner ¶

type LVDriverProvisioner interface {
	Create(context.Context, string, []string) error
}

type LVDriverResizer ¶

type LVDriverResizer interface {
	Size(context.Context) (int64, error)
	Resize(context.Context, int64) error
}

LVDriverResizer is implemented by the lv implementations that can report and change their size. A resource whose implementation does not is refused when a resize is planned, not when it is applied.

type LVDriverUnprovisioner ¶

type LVDriverUnprovisioner interface {
	Remove(context.Context, []string) error
}

type LVDriverWiper ¶

type LVDriverWiper interface {
	Wipe(context.Context) error
}

type T ¶

type T struct {
	resdisk.T
	LVName        string   `json:"name"`
	VGName        string   `json:"vg"`
	Size          string   `json:"size"`
	CreateOptions []string `json:"create_options"`
}

func (*T) Boot ¶

func (t *T) Boot(ctx context.Context) error

func (*T) ClaimedDevices ¶

func (t *T) ClaimedDevices(ctx context.Context) device.L

func (*T) CurrentSize ¶

func (t *T) CurrentSize(ctx context.Context) (int64, error)

CurrentSize implements resource.Sizer.

func (*T) DriverID ¶

func (t *T) DriverID() driver.ID

func (*T) ExposedDevices ¶

func (t *T) ExposedDevices(ctx context.Context) device.L

func (*T) Info ¶

func (t *T) Info(ctx context.Context) (resource.InfoKeys, error)

func (*T) Label ¶

func (t *T) Label(_ context.Context) string

Label implements Label from resource.Driver interface, it returns a formatted short description of the Resource

func (*T) Manifest ¶

func (t *T) Manifest() *manifest.T

Manifest exposes to the core the input expected by the driver.

func (*T) PoolCharge ¶

func (t *T) PoolCharge() (string, int64)

PoolCharge implements resource.PoolCharger. A logical volume takes its size of the volume group it is carved from.

A size that is a share of the group, "100%FREE" and the like, is not a number the group can be rationed by, and is answered as none.

func (*T) ProvisionAsLeader ¶

func (t *T) ProvisionAsLeader(ctx context.Context) error

func (*T) Provisioned ¶

func (t *T) Provisioned(ctx context.Context) (provisioned.T, error)

func (*T) Resize ¶

func (t *T) Resize(ctx context.Context, to int64) error

Resize implements resource.Resizer.

func (*T) ResizePlan ¶

func (t *T) ResizePlan(ctx context.Context, to int64) (int64, error)

ResizePlan implements resource.Resizer.

A logical volume holds what it is given, so it asks the volume group below it for the same size.

func (*T) ResizeRestsOn ¶

func (t *T) ResizeRestsOn(_ context.Context) string

ResizeRestsOn implements resource.ResizeRestsOn.

A logical volume takes its space from its volume group, which no device leads to: what a volume group exposes is the logical volumes themselves.

func (*T) Start ¶

func (t *T) Start(ctx context.Context) error

func (*T) Status ¶

func (t *T) Status(ctx context.Context) status.T

func (*T) Stop ¶

func (t *T) Stop(ctx context.Context) error

func (*T) SubDevices ¶

func (t *T) SubDevices(ctx context.Context) device.L

func (*T) UnprovisionAsLeader ¶

func (t *T) UnprovisionAsLeader(ctx context.Context) error
