Abstract:
A method for repairing a corrupted filesystem, whereby the corrupted filesystem includes a plurality of corrupted metadata structures is provided. The method may include determining a plurality of missing metadata structures associated with the corrupted filesystem. The method may also include determining a plurality of current addresses corresponding to a plurality of valid metadata structures in a hierarchical metadata structure of the corrupted filesystem. The method may further include locating the plurality of missing metadata structures and a plurality of addresses associated with the missing metadata. The method may also include rebuilding the plurality of missing metadata structures based on the located plurality of addresses associated with the missing metadata structures, whereby the rebuilding comprises assigning the located plurality of address to the plurality of missing metadata structures and redirecting the plurality of missing metadata structures to point to a correct plurality of other metadata structures.
