The present disclosure is directed to managing write commands for a storage system implementing address indirection. In some storage systems, a mapping table that provides logical-to-physical mapping may have individual entries that each references a logical address size that exceeds the size of an atomic write to the storage media. In such systems, a write to a logical address is not atomic as it may require several discrete physical writes that may individually fail. The techniques presented employ several pre-commit and post-commit actions to save data that enables the storage system to make writes to these logical addresses atomic and prevent undue delay on powerup.
