Abstract
A method performed by a computing device having memory is provided. The method includes (a) detecting corruption in a first page description block (PDB) of a plurality of PDBs stored in sequence in the memory, each PDB storing a set of page descriptors (PDs) that point to pages of data sequentially stored in the memory that are part of a single transaction, PDBs that represent the same transaction being contiguous within the sequence; (b) searching for a second PDB of the plurality of PDBs, the second PDB satisfying the following criteria: (1) it is not corrupted, and (2) it represents a same transaction as the first PDB; and (c) reconstructing the first PDB using the second PDB. An apparatus, system, and computer program product for performing a similar method are also provided.
