摘要： Metadata is extracted from a filesystem of a first system. The filesystem includes user data and the metadata. The metadata relates to the user data and is corrupt. Just the just the metadata extracted from the filesystem is transmitted from the first system to a second system. The second system receives the transmitted metadata, and loads this metadata to create a dummy namespace reflecting the metadata. The second system debugs the metadata, and prepares a patch based on this debugging. Execution of the patch allows the metadata to be repaired so that the metadata is no longer corrupt. The patch is transmitted from the second system to the first system for execution at the first system to allow the metadata to be repaired at the first system so that the metadata is no longer corrupt at the first system.

摘要翻译： 从第一个系统的文件系统中提取元数据。 文件系统包括用户数据和元数据。 元数据与用户数据有关，并且已损坏。 只是从文件系统提取的元数据从第一个系统传输到第二个系统。 第二个系统接收传输的元数据，并加载该元数据以创建反映元数据的虚拟命名空间。 第二个系统调试元数据，并根据此调试准备一个补丁。 修补程序的执行允许元数据被修复，以便元数据不再被破坏。 该补丁从第二系统传送到第一系统以便在第一系统执行，以允许在第一系统修复元数据，使得元数据在第一系统不再被破坏。
