Abstract

A controller-implemented method, according to one embodiment, includes: examining, by the controller, each of a plurality of journal entries from at least one journal beginning with a most recent one of the journal entries in a most recent one of the at least one journal and working towards an oldest one of the journal entries in an oldest one of the at least one journal, the journal entries corresponding to one or more updates made to one or more logical to physical table (LPT) entries of a LPT; determining, by the controller, whether a current LPT entry, which corresponds to a currently examined journal entry, has already been updated; and discarding, by the controller, the currently examined journal entry in response to determining that the current LPT entry has already been updated.
