    • 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. A means is provided for identification during takeover of the coredump disk and SCSI-3 reservations are employed to coordinate write access to (ownership of) shared disks, so as to prevent takeover from interfering with coredump while simultaneously preventing the failed filer is from continuing to write regular file system disks being taken over by its partner.
    • 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。 提供了一种用于在核心转储磁盘接管期间进行识别的手段,并采用SCSI-3保留来协调对共享磁盘的(所有权)的写入访问,以防止接管干扰核心转储,同时防止失败的文件管理器继续写入 常规文件系统磁盘由其合作伙伴接管。
