Abstract: This invention provides a system and method for selecting and communicating a single disk (a "coredump disk") for use in a coredump procedure by a failed file server (or filer). A selection method on the failed filer determines the "best candidate" coredump disk according to a predetermined set of criteria. For example, the available disks that can receive coredump data are located and ordered so as to pre­fer disks that best match the coredump data size requirement, are least likely to be needed for normal service by the server; and require the least preparation to receive coredump data. Appropriate attributes on the selected coredump disk are written to indicate that a coredump is in progress, and the location of the coredump data. Upon reboot of the failed filer (or takeover by a cluster partner), the coredump disk is identified and the coredump data recovered by reading back appropriate attrib­utes.

Abstract translation: 本发明提供了一种用于选择和通信由故障文件服务器（或文件管理器）在核心转储器过程中使用的单个盘（“核心转储盘”）的系统和方法。 故障文件管理器上的选择方法根据预定的一组标准确定“最佳候选”核心转储盘。 例如，可以接收coredump数据的可用磁盘是定位和排序的，以便更好地匹配coredump数据大小要求的磁盘，服务器的正常服务最不可能需要; 并要求最少的准备接收coredump数据。 写入所选coredump磁盘上的适当属性，以指示coredump正在进行，以及coredump数据的位置。 在重新启动失败的文件管理器（或由群集合作伙伴接管）时，将通过读取适当的属性来识别核心转储磁盘并恢复核心转储器数据。
