Abstract
A storage control system is configured to obtain first data associated with a logical data device and to store the first data in a first entry of a log-structured array. The storage control system is further configured to invalidate a second entry of the log-structured array based at least in part on the storage of the first data in the first entry. The second entry comprises second data that was associated with the logical data device prior to obtaining the first data. The storage control system is further configured to determine that a first indication in a first metadata indicates that the invalidated second entry corresponds to a transaction log and to defer reclamation of the second entry based at least in part on the determination that the first indication in the first metadata indicates that the invalidated second entry corresponds to the transaction log.
