Abstract
In at least one embodiment, processing can include: maintaining a storage object identifier hash table (SOIDHT) that tracks storage object identifiers (IDs) that have been reassigned among storage objects and that have potential outstanding activity associated with storage objects as prior to performing corresponding reassignments; recording, in a user data (UD) log, a UD log entry corresponding to an operation directed to a storage object assigned a storage object ID, wherein the UD log entry includes a first LSN denoting a point in time when the operation is recorded in the UD log; and flushing the UD log. Responsive to determining that the storage object has a corresponding SOIDHT entry, processing can include determining whether the first LSN of the first UD log entry of the operation is less than a second LSN of the corresponding entry of the SOIDHT.
