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通过失败的文件服务器（或文件管理器）选择和传送单个磁盘（“核心盘”）以用于核心转储过程的系统和方法。 失败的文件管理器上的选择方法根据预定的一组标准来确定“最佳候选者”核心盘。 例如，可以接收coredump数据的可用磁盘的位置和顺序是为了选择最符合coredump数据大小要求的磁盘，而服务器对于正常服务最不可能需要磁盘; 并且需要最少的准备来接收核心转储数据。 写入所选coredump磁盘上的适当属性以指示正在进行coredump，以及coredump数据的位置。 重新启动失败的文件管理器（或由群集伙伴接管）后，将识别coredump磁盘，并通过读取适当的属性来恢复coredump数据。
