Abstract:
1. A method of correcting object handles, the method being performed by a processor of a storage system and comprising: accessing, by the processor, a redirector file stored on a first logical data container, the redirector file including (i) a forward object handle pointing to a first data object stored on a second logical data container, and (ii) a first checksum of the forward object handle; determining a second checksum of the forward object handle; comparing the first checksum with the second checksum; and selectively modifying the redirector file based at least in part on the comparison; detecting a mismatch between the first checksum and the second checksum based on the comparison; extracting backward object handles associated with data objects stored on the second logical data container; and identifying a backward object handle, from the extracted backward object handles, that points back to the redirector file, wherein the identified backward object handle is associated with a second data object.
