可以在不同的分区之间动态地分配和重新分配资源，而不会影响其他分区，也无需重新启动这些分区。
Resources can be dynamically assigned and reassigned among different partitions, without disturbing other partitions or requiring a reboot of the partitions.
在如下的例子中，Table1创建于数据库分区1、2、3和4并且会基于列COL1上的一个分区键重新分配。
In the following example, Table1 is created on database partitions 1, 2, 3, and 4, and is redistributed based on a partitioning key on column col1.
在小型系统中，LVM允许按照需求简单的重新分配分区大小，从而不用去估量一个分区可能需要多大。
On small systems (like a desktop at home), instead of having to guess how big a partition needs to be, LVM allows you to resize your disk partitions easily as needed.
