Abstract
Data is stored as a first collection of memory blocks distributed across a first set of memory devices. It is determined that a first memory device in the first set is in a degraded state. Data is recovered corresponding to a first memory block in the first collection of memory blocks that is stored in the first memory device, which is configured to include a first number of memory blocks. The recovered data is stored in a second memory device as a new memory block, which is added to the first collection of memory blocks. The first memory device is removed from the first set and reconfigured with a second number of memory blocks that is less than the first number of memory blocks. Memory blocks in a second collection of memory blocks distributed across a second set of memory devices is stored in the reconfigured first memory device.
