Abstract
In an approach to extending the lifespan of a flash-based storage device, responsive to receiving a signal from a storage device that the storage device is low on extra blocks, one or more free logical blocks that are no longer needed are released. The storage device is notified of the one or more free logical blocks that are no longer needed. Responsive to determining that the number of valid physical blocks is greater than the number of used logical blocks, the advertised capacity of the storage device is reduced.
