If you have configured a primary node ( that is, one that is favored to gain the floating resource above all others), it will regain the floating resources automatically.

It's still possible to lose data ( for example, if both nodes failed), but failure of the primary node will not cause data loss, because the data has been replicated.

这仍然可能丢失数据（例如，如果两个节点都发生故障），但是主节点故障不会引起数据丢失，因为数据已经被复制了。

All writes are directed to the primary node, from where they are replicated while reads can be performed on any node.

所有的写操作都被分发到主节点，而读操作可以在任何节点上进行。

In the active/ passive model, the primary node is used for Read and Write operations for all users.

在主动/被动模式下，主节点用于所有用户的读写操作。

The primary node has ownership of the shared volume group as it is varied-on and active.

主节点在启动并处于活跃状态时拥有共享卷组。

A primary node type defines the characteristics of the node, such as the properties and child nodes that the node is allowed to have.

主节点类型定义了节点的特征，例如允许节点拥有的属性和子节点。

In addition to the primary node type, a node may also have one or more mixin types.

除了主节点类型之外，节点还可以有一个或多个混合（mixin）类型。

In this error scenario, the communication link fails between the nodes, and both nodes believe that they are the primary node.

在这个错误场景中，节点之间的通信链发生故障，每个节点都认为自己是主节点。

In the case of an e-commerce system, the primary node could be either an order or a customer.

如在一个电子商务系统中，主要节点可以是一个订单或者一个客户。

Use the ps command to make sure the Web server daemons are running on the primary node.

使用ps命令来确保Web服务器后台进程正在主节点上运行。

Because driver maintains connection to both nodes while write transactions are directed to the primary node, read transactions can be directed to either node.

由于驱动程序维护与两个节点的连接，同时写事务被定向到主节点，因此读事务可以定向到任何一个节点。

Scaling down is like a failback operation without the task of bringing the primary node up.

向下扩展就像退回操作，其中没有将主节点置于在线的任务。

In the example environment, running lspv on the primary node confirms the shared volume group is in concurrent mode.

在示例环境中，在主节点上运行lspv以确认共享卷组处于并发模式。

The middle column should be the hostname of the primary node.

中间一列应该是主节点的主机名。

The DB2 database installed with the primary node is automatically used by all other nodes in the cluster.

与主节点安装在一起的DB2数据库自动被集群中所有其他节点使用。

Instead, every time a disk write is issued, that write is done on the primary node and sent over to the backup node and written to disk there, as well.

相反，每次有一个磁盘写入操作发出时，就会在主节点上执行该操作，并且也会被发送到备份节点，在那里的磁盘上完成此写入操作。

Use the ps command to make sure WebSphere MQ is running on the primary node.

可以使用ps命令来确认WebSphere MQ正在主节点上运行。

Note that I am using the cluster address in the above URLs and not the address of the primary node.

注意，在上面我使用的是群集地址，而不是主节点的地址。

This is usually easiest by focusing on the primary node of a domain.

这可以通过聚焦域中的主要节点实现。

Allow the secondary node to access objects backed up on the primary node ( this has to be done on the primary machine)

允许辅助节点访问备份在主节点上的对象（必须在主机器上完成）

Every node has one and only one primary node type.

每个节点都有且只有一个主节点类型。
