Abstract: A system, method, and machine-readable storage medium for recovering data in a distributed storage system are provided. In some embodiments, the method includes identifying a failing storage device of a first storage node having an inaccessible data segment. When it is determined that the inaccessible data segment cannot be recovered using a first data protection scheme, a first chunk of data associated with the inaccessible data segment is identified and a group associated with the first chunk of data is identified. A second chunk of data associated with the group is selectively retrieved from a second storage node such that data associated with an accessible data segment of the first storage node is not retrieved. The inaccessible data segment is recovered by recovering the first chunk of data using a second data protection scheme and the second chunk of data.

Abstract: Technology is disclosed for subpartitioning a namespace region. In various embodiments, the technology creates at least two subpartitions from a partitioned namespace, wherein the partitioned namespace corresponds to at least two different name nodes of the large scale data storage service; and stores data corresponding to each subpartition as a separate file, e.g., so that it can be easily mounted by an operating system executed by a different computing device.

Abstract translation: 公开了用于分区命名空间区域的技术。 在各种实施例中，该技术从分区命名空间创建至少两个子分区，其中分区命名空间对应于大规模数据存储服务的至少两个不同的名称节点; 并且将与每个子分组相对应的数据存储为单独的文件，例如，使得其可以由由不同的计算设备执行的操作系统容易地安装。
