func (*T) ReservableDevices ¶

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

func (*T) Resize ¶

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

Resize implements resource.Resizer.

It grows the array onto members that have grown already, and does not reshape: the members and the level stay as they are.

An array hands out what its data members hold together, and how many of them that is depends on the level: one for a raid1, all of them for a raid0 or a linear, n-1 for a raid5, n-2 for a raid6, n divided by the copies for a raid10. Rather than enumerate the levels and the raid10 layouts, the array is asked what it already does: its size divided by what it uses on each member is exactly the number of members its size is made of.

A member size is a whole number of chunks on a striped level, so it is rounded up to one, never down: the link above asked for a size it needs.
