Abstract: Failure information associated with a plurality of blocks of a solid-state storage device of a plurality of solid-state storage devices is received. One or more blocks of the plurality of blocks storing uncorrectable data are identified based on the received failure information. A partial deallocation of the one or more blocks of the plurality of blocks is issued, the partial deallocation indicating that the one or more blocks store uncorrectable data. A remedial action associated with the one or more blocks of the plurality of blocks is performed.

Abstract: An indication is received from a storage device that an attempt to read a portion of data from a block of the storage device has failed. A command is transmitted to the storage device to perform a scan on data stored at the block comprising the portion of data to acquire failure information associated with a plurality of subsets of the data stored at the block. The failure information associated with the plurality of subsets of the data stored at the block is received from the storage device.
