Abstract: A method effectively preventing a requesting node from unfencing and mounting a file system subsequent to a failure in a cluster file system having a plurality of active nodes. The method comprising first upgrading one active node in the cluster to function as a cluster manager node. The cluster manager is in communication with all nodes. The cluster manager is assigned manager responsibilities, in part, comprising first receiving an active status request from the node requesting to mount a file system. The cluster manager first queries the quorum nodes to determine whether each node considers the cluster manager to still have cluster management responsibilities for the file system. If a majority of quorum nodes consider the cluster manager to still have cluster management responsibilities for the file system then the cluster manager responds to the requesting node's active status request. Thereafter, the requesting node proceeds with mounting the file system.

Abstract translation: 一种有效地防止请求节点在具有多个活动节点的群集文件系统中在失败之后忽略并挂载文件系统的方法。 该方法包括首先升级集群中的一个活动节点以充当集群管理器节点。 集群管理器与所有节点通信。 集群管理器被分配经理责任，部分包括首先从请求装载文件系统的节点接收活动状态请求。 集群管理器首先查询仲裁节点，以确定每个节点是否认为集群管理器仍然具有文件系统的集群管理职责。 如果大多数仲裁节点认为集群管理器仍然具有文件系统的集群管理职责，那么集群管理器将响应请求节点的活动状态请求。 此后，请求节点继续安装文件系统。
