发生裂脑之后,同步存储最简单的方法是在链接出现故障时其中一个节点没有发现改变。
The simplest approach to synchronizing storage after split-brain is when one node saw no changes occur while the link was down.
Laurent谈到了两个典型的关于故障转移的例子,并解释JPPF如何在这种情况下切换到一个不同的节点。
Laurent talked about 2 typical cases of failure and how JPPF fails over to a different node in these scenarios.
这允许存储节点复制数据(当发现一个设备出现故障时)。
This allows the storage nodes to replicate data (when a device is found to have failed).
为了优化机器的使用并维护HA,我们在每个站点设计了一个4节点集群:一个节点对应一个应用程序,剩下的一个节点充当故障转移节点。
To optimize the use of machines and to maintain ha, we designed for a four-node cluster at each site: one node per application and a spare node that will serve as the failover node.
如果集群中的任何节点发生故障,那么用户会被重定向到系统中的另一个功能节点,而他或她的会话会继续,就像什么也没发生一样。
If any of the nodes in the cluster were to fail, a user would be redirected to another functional node in the system, and his or her session would continue as if nothing had happened.
由于您只有两个节点,因此要为每个节点的每个集群分配一个成员,以确保执行故障转移。
Since you only have two nodes, you will assign a member of each cluster to each node to ensure failover.
服务器会检测到这个故障,并自动将未完成的工作转移到另外一个节点。
The server will detect the failure and automatically submit the incomplete work to another node.
高可用性—避免一个生产级应用程序在任何节点上发生故障的要求—对于任何标准而言都不是什么新概念;许多软件产品都致力于解决这个问题。
High availability, the requirement to protect a production-grade application against a failure of any node, isn't a new concept by any standard; many software products address this challenge.
故障转移是群集的另一个功能,表示在任何时候,如果群集中的某个节点发生故障,用户会话的状态会在群集中的另一台机器上保留。
Failover is another feature of this, meaning that at any time, one of the nodes in the cluster could fail, and the state of a user's session would survive on another machine in the cluster.
在故障恢复过程中,其中一个子节点会成为主节点,而所有复制将从该节点开始。
During failover, one of the children becomes the master node and all replication starts flowing from that node.
如果有一个成员(我们称为“节点”)宕机,需要立即通知其他节点,从而让应用程序和客户端进行故障转移,而不会中断服务。
If a member (which we will call "node") goes down, the other nodes need to be informed immediately so that applications and clients can fail-over without disruption.
主要服务器故障恢复到一个新的次要节点(SDS或HDR)上不会影响存档,或者受存档的影响,而RSS节点上会制作一份外部存档。
Primary fail-over to a new secondary node (SDS or HDR) will not impact the archive, or be impacted by the archive, while an external archive is being taken on an RSS node.
节点代理和客户机将自动尝试第一个(主要)地址,然后进行故障转移,尝试第二个(备份)地址。
The node agents and clients will automatically try the first (primary) address and then failover to try the second (backup) address.
此外,成对的故障转移节点允许节点和所有的资源(包括MQ)作为一个单元转移到被动机上。
Additionally, the pairing of the failover node allows for the node and all of its resources, including MQ, to fail over as a single unit to the passive machine.
即使只有一个节点是活动的,完全运行的节点也会由于网络故障丢失它与同级系统之间的连接,或者,如果两个非活动的同级系统同时暂停,资源将被自动释放。
Even if a single active, 100% operational node loses connection to its peer systems due to network failure or if both the inactive peers halt simultaneously, the resource will be voluntarily released.
在一个2节点集群中,当一个节点发生故障或网络连接中断,每个节点都会充当主要节点并开始与外界交互。
In a two-node cluster, when one fails or the network connection snaps, each node believes that it is the master and starts interacting with the outside world.
当一个节点出现故障,其他节点检测的条件,并确定在数据库中,在进步在该故障节点的工作。
When a node fails, the other nodes detect the condition and identify the jobs in the database that were in progress within the failed node.
故障切换时发生一个节点失败,而在执行一项或多项工作之中。
Fail-over occurs when one of the nodes fails while in the midst of executing one or more jobs.
在节点上只找到一个网络适配器。请添加另一个网络适配器以避免单一故障点。
Only one network adapter was found on the node. Add another network adapter to avoid a single point of failure.
为了解决动态故障树研究领域的马尔可夫链状态空间爆炸问题,给出了一个基于同构节点的动态故障树分析方法。
In order to solve the problem of state space explosion of Markov chains in the research field of dynamic fault tree, a new method based on isomorphic node is presented.
本文着重于线性网络的故障诊断,只用一个单位测试电流,通过量测各节点电压,来确诊元件故障。
In this paper we discussed the fault diagnosis of linear network. Using only one unit-test-current and measuring various node voltages, we can diagnose the faulty elements.
我们在业内率先经销微软的群集服务器,该服务器可为两个计算节点提供共享存储器,如一个节点出现故障,服务器可重新启动另一个节点的应用程序。
We were the first in the industry to ship Microsoft Cluster Server, which provides Shared storage between two computing nodes and automatically restarts an application on another node if one fails.
其中,由于无线传感器网络是一个没有基础设施的自组织无线移动网络并且传感器网络中的节点很容易发生故障或者能量耗尽导致通信中断。
Besides, in WSN, there is no fixed or pre-defined infrastructure and the nodes need to carry other nodes'traffic and are vulnerable to fail.
