A scenario in which volume management would be useful is when you have a storage server that has filled up with data and storage needs to be added.
在这种情形下卷管理将会适用：您的某个存储服务器已经存满数据，需要添加存储空间。
Split or merge volume groups in situ (as long as no logical volumes span the split). This can be useful when migrating whole logical volumes to or from offline storage.
在原处分开或者合并卷组。当将整个逻辑卷迁移到下线存储或者从下线存储迁移时是非常有用的。
