是否可以将物理盘区的子范围从物理卷末尾的段移动到物理卷中间的未分配范围？ （子范围具有与未分配范围相同的范围数。）
例如，我想通过将最后一个段的最后 256 个扩展区移动到扩展区 50688-50943，将未分配的扩展区（扩展区 50688-50943）移动到物理卷的末尾：
# pvmove --test --alloc anywhere /dev/mapper/cryptdisk:60694-60949 /dev/mapper/cryptdisk:50688-50943
TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.
以下是物理卷的盘区信息：

您需要将所有已使用的扇区移动到末尾，即第一个空闲扇区：
pvmove --alloc anywhere /dev/mapper/cryptdisk:50944-60949/dev/mapper/cryptdisk:50688-60693
