Abstract: Techniques are disclosed relating to synchronizing state information across nodes in a cluster. In one embodiment, a first cluster node receives a request to update state information for a logical volume of the cluster. The first cluster node acquires a lock from a distributed lock manager of the cluster, the lock controlling modification of the state information. In response to acquiring the lock, the first cluster node updates the state information across cluster nodes of the cluster. In one embodiment, first cluster node updates the state information in some, but not all, of the cluster nodes. In some embodiments, the first cluster node updates the state information across only cluster nodes associated with the logical volume.

Abstract translation: 公开了关于跨群集中的节点同步状态信息的技术。 在一个实施例中，第一集群节点接收到用于更新集群的逻辑卷的状态信息的请求。 第一个集群节点从集群的分布式锁管理器获取锁，控制状态信息的修改。 响应于获取锁，第一个集群节点在集群的集群节点之间更新状态信息。 在一个实施例中，第一集群节点在一些但不是全部的集群节点中更新状态信息。 在一些实施例中，第一集群节点仅在与逻辑卷相关联的集群节点上更新状态信息。
