Abstract
In some embodiments, a storage system comprises at least one processor coupled to memory. The processor is configured to obtain a write operation that comprises first data associated with a logical data device and to store the first data in a first entry of a log-structured array (LSA). The at least one processor is configured to invalidate a second entry based at least in part on the storage of the first data in the first entry. The second entry comprises second data associated with the logical data device that was stored in the second entry prior to obtaining the write operation. The at least one processor is configured to determine that a first indication in LSA metadata associated with the LSA indicates that the invalidated second entry comprises data that is awaiting replication and to defer reclamation of the second entry based at least in part on the determination.
