Abstract
Volumes of a file system environment are taken offline when they require repair for confirmed corruptions. Applications utilize handles, both real and, in environments where proxy file systems are overlaid upon the real file system(s), proxy, to access objects stored on volumes of a file system environment. Real handles are closed when the volume storing the objects for the real handles is taken offline, terminating applications' access to the volume's objects. New real handles are automatically generated for those volume objects that had a real handle prior to the volume going offline for corruption correction processing and which were not altered during the corruption correction processing. Applications accessing these objects can continue to use their original proxy handle, which is subsequently correlated with an automatically established new real handle, to access the objects.
