Abstract
A method for managing metadata for data stored in a cloud storage is provided. The method receives, at a first of a plurality of metadata servers, information associated with an object stored in the cloud storage, the information comprising a plurality of LBAs for where the object is stored. Each metadata server allocates contiguous chunk IDs for a group of objects. The method generates a new chunk ID for the object, which is a combination of a unique fixed value and a monotonically incrementing local value associated with each LBA, such that a first LBA is mapped to a first chunk ID having a first local value and a next LBA is mapped to a second chunk ID having the first local value incremented as a second local value. The method stores the new chunk ID and other metadata in one or more tables stored in a metadata storage.
