摘要： A method of managing a triggerable task in a cluster environment is described. The method includes accessing a definition of a task, wherein the definition includes a triggering event, and an action to be performed when the triggering event occurs. The method further includes, accessing a cluster policy defining how triggering events are interpreted on a node task basis for a plurality of nodes in a cluster. Based on the cluster policy, the method includes determining that the triggering event has occurred. As a result of the determination that the triggering event has occurred, the method further includes attempting to perform the action.

摘要： Managing a distributed system. Embodiments may allow for a quorum to dynamically change the quorum vote. One example is illustrated in a method. The method includes determining a change to a voter's level of participation in a cluster. A quorum of voters changes the voter's voting privileges, based on the change in the voter's level of participation.

摘要： The present invention extends to methods, systems, and computer program products for automatically transferring configuration of a virtual machine from one cluster to another cluster. The invention enables an administrator to transfer configuration of a virtual machine by simply specifying a virtual machine to be transferred. The invention then inspects the configuration of the virtual machine on the old cluster as well as the configuration of the old cluster, including the storage (e.g. virtual hard disk) used by the cluster, and then configures a new virtual machine on a new cluster accordingly to match the configuration of the old virtual machine. Similar techniques can also be applied to transfer configuration of an SMB file server.

摘要： Described is a technology by which an owner node in a server cluster maintains ownership of a storage mechanism through a persistent reservation mechanism, while allowing non-owning nodes read and write access to the storage mechanism. An owner node writes a reservation key to a registration table associated with the storage mechanism. Non-owning nodes write a shared key that gives them read and write access. The owner node validates the shared keys against cluster membership data, and preempts (e.g., removes) any key deemed not valid. The owner node also defends ownership against challenges to ownership made by other nodes, so that another node can take over ownership if a (formerly) owning node is unable to defend, e.g., because of a failure.
摘要翻译：描述了一种技术，通过该技术，服务器集群中的所有者节点通过持久预留机制来维护存储机制的所有权，同时允许非拥有节点对存储机制进行读写访问。所有者节点将预留密钥写入与存储机制相关联的注册表。非拥有节点写入一个共享密钥，为其提供读写访问权限。所有者节点根据集群成员数据验证共享密钥，并抢占（例如，删除）任何被认为无效的密钥。所有者节点还保护所有权不受其他节点所有权的挑战，从而如果（以前拥有）节点无法保护，例如由于失败，另一个节点可以占有所有权。
