DOS主分区中的数据将全部丢失。你准备删除哪个主分区?

如果数据库设计者已在表上创建了主分区索引,那么查询应当与分区列结合。
If the database designer has created a Primary partition Index on a table, queries should incorporate the partitioning column.
如果想要获得更多的分区,主分区中的一个可以被转换为扩展分区。
To get more partitions one of the primary partitions can be turned into an extended parititon.
如果需要超过4个分区,就需要放弃一个主分区来创建一个扩展分区。
If you need more than four partitions, give away one primary partition to create an extended partition.

当你重新启动系统,它会回复到原来的状态,所有的变化,以自己的主分区将消失。
Once you restart your system it will revert back to its original state and all changes to your primary partition will disappear.
例如,您不能缩小某个文件系统,以及您需要在新的布局中周密计划主分区与逻辑分区的配置。
For instance, you can't shrink certain file systems, and you may need to carefully plan the positioning of primary versus logical partitions in your new layout.
如果您想要从逻辑分区腾出空间给主分区,您必须显式地调整围绕逻辑分区的扩展分区,反之一样。
If you want to take space from a logical partition to give it to a primary partition or vice versa, you must explicitly resize the extended partition that surrounds the logical partitions.
这一配对包括了主分区中的虚拟服务提供者(vsp),它负责和每个虚拟机中的虚拟服务客户端(VSC)交互。
That pairing includes a virtualization service provider (VSP) in the primary partition whose job is to interact with virtualization service clients (VSC) in each virtual machine.
如果原始分区(主分区)出现故障,将把它的一个副本提升为新主分区,然后在其他地方创建一个新副本。
If the original partition (the primary partition) fails, one of its replicas is promoted to become the new primary, and then a new replica is created somewhere else.
注意主分区是从1到4进行编号的,编号系统可能有间隙,但是逻辑分区是从5开始编号的,不存在间隙。
Note that primary partitions are numbered from 1 to 4, and the numbering system may contain gaps, whereas logical partitions are numbered from 5 up and may not contain gaps.
如果需要4个以上的主分区(往往需要4个以上的主分区),其中一个主分区就必须以扩展分区的形式出现。
When more than four partitions are required, as is often the case, one of the primary partitions must instead become an extended partition.
使用异步副本是一个备选方案,这可以避免同步副本带来的某些性能开销,但是这不能保证与主分区始终同步。
Using asynchronous replicas is an alternative that avoids some of the performance overhead of synchronous replicas, but they are not guaranteed to be identical to the primary at all times.
虽然文件系统很多种,但分区类型只有三种:主分区,扩展分区,逻辑分区,其中逻辑分区是在扩展分区中的。
While there are tons of file system types, there are only three kinds of partitions: primary, extended, and logical.
这个只跟硬盘有关,跟操作系统是什么没有关系。主引导记录告诉机器从哪里启动系统,所以一般来说主分区是安装系统的。
This limitation is due to something called the Master Boot Record which tells the computer which partitions it can boot from, and so primary partitions are usually reserved for operating systems.
因此,如果您添加一个主分区,分区编号也有可能不会改变,但是如果您要添加一个逻辑分区,您所有的其他逻辑分区变化都会改变。
Thus, if you add a primary partition, it's possible that no partition Numbers will change; but if you add a logical partition, all your other logical partitions' Numbers may change.
然而,这是一种笨拙的权宜之计,会导致一些问题。比如,安装多个操作系统时,如果过多的操作系统要求自身拥有过多的主分区,就会出现困难。
This is, however, an ugly workaround that creates its own problems, such as difficulties installing multiple operating systems when too many of them want too many primary partitions to themselves.
