5.6. 在线数据重定位
			您可以使用 
pvmove 命令在系统还在使用时移动数据。
		pvmove 命令将数据分成片段,并生成临时镜像来移动每个片段。有关 pvmove 命令操作的详细内容请参考 pvmove(8) man page。
		注意
				In order to perform a 
pvmove operation in a cluster, you should ensure that the cmirror package is installed and the cmirrord service is running.
			
			下面的命令将物理卷 
/dev/sdc1 中所有分配了的空间都移动到卷组中其它可用物理卷中:
		pvmove /dev/sdc1
# pvmove /dev/sdc1
			The following command moves just the extents of the logical volume 
MyLV.
		pvmove -n MyLV /dev/sdc1
# pvmove -n MyLV /dev/sdc1
			Since the 
pvmove command can take a long time to execute, you may want to run the command in the background to avoid display of progress updates in the foreground. The following command moves all extents allocated to the physical volume /dev/sdc1 over to /dev/sdf1 in the background.
		pvmove -b /dev/sdc1 /dev/sdf1
# pvmove -b /dev/sdc1 /dev/sdf1
			下面的命令以 5 秒为间隔,以百分比形式报告移动的过程。
		
pvmove -i5 /dev/sdd1
# pvmove -i5 /dev/sdd1
