摘要： Methods, systems, and apparatus, including computer program products feature selecting a file in a distributed file system. The file is associated with a time to live derived from a path name for the file. The file is divided into a plurality of chunks that are distributed among a plurality of servers. Each chunk has a respective modification time indicating when the chunk was last modified. A latest respective modification time among the respective modification times of each of the plurality of chunks is selected. A determination is made as to whether an elapsed time based on the latest modification time is equal to or exceeds the time to live. Each of the chunks of the file is deleted responsive to the determination. Other embodiments of this aspect include corresponding systems, apparatus, and computer program products.

摘要： A method for handling a fault in a storage system comprises maintaining data in a mass storage subsystem and providing access to the data on behalf of a client. The method further comprises detecting a fault in a volume of data stored in the mass storage subsystem, determining a severity of the fault, and selecting a course of action in response to the fault, based on the severity of the fault.

摘要： Systems and methods of performing lightweight fault monitoring and analysis are described. In certain embodiments, the lightweight fault monitoring and analysis system and method include a crash dump component operable to generate a lightweight core file for a machine without generating a complete core file. The lightweight core file is smaller in size than a complete core file and contains information relevant for fault monitoring and analysis. The lightweight core has a data structure portion reflecting the state of only a portion of actual working memory at the time of a problem. The lightweight core file contains both regions in memory specific to the problem encountered and some standard regions.
摘要翻译：描述执行轻量级故障监测和分析的系统和方法。在某些实施例中，轻量级故障监测和分析系统和方法包括可以为机器生成轻量级核心文件而不产生完整的核心文件的故障转储组件。轻量级核心文件的大小小于完整的核心文件，并包含与故障监控和分析相关的信息。轻量级核心具有在问题时仅反映实际工作存储器的一部分的状态的数据结构部分。轻量级核心文件包含内存中特定于遇到问题的某个标准区域的两个区域。
