Abstract: A system and method for allowing more rapid takeover of a failed filer by a clustered takeover partner filer in the presence of a coredump procedure (e.g. a transfer of the failed filer's working memory) is provided. To save time, the coredump is allowed to occur contemporaneously with the takeover of the failed filer’s regular, active file service disks by the partner so that the takeover need not await completion of the coredump to begin. This is accomplished, briefly stated, by the following techniques. The coredump is written to a single disk that is not involved in regular file service, so that takeover of regular file services can proceed without interference from coredump. A reliable means for both filers in a cluster to identify the coredump disk is provided, which removes takeover dependence upon unreliable communications mechanisms.

Abstract translation: 提供了一种用于在存在核心转储程序（例如，失败的文件管理器的工作存储器的传送）的情况下允许由集群接管合作伙伴文件管理器更快速地接管失败的归档器的系统和方法。 为了节省时间，核心转储器被允许与合作伙伴接管失败的文件管理器常规的活动文件服务磁盘同时发生，以便接管无需等待核心转储完成。 这通过以下技术简要说明了。 coredump写入不涉及常规文件服务的单个磁盘，因此可以在不受coredump干扰的情况下继续执行常规文件服务。 提供了集群中的两个文件管理器来识别核心转储磁盘的可靠方法，这消除了对不可靠的通信机制的接管依赖。
