This article will explain in detail about the use of linux's pvmove command to move the physical disk. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The purpose of the pvmove command is to move the physical extent on the source physical volume to one or more other target physical volumes.

You can specify a source log or volume when using the pvmove command. In this case, only the extent used by the logical volume is moved to the free or specified zone on the target physical volume. If no physical volume is specified, it is assigned using the default rules of the volume group.

If the pvmove command is interrupted for any reason (such as a machine crash), the pvmove command restarts any operation that was in progress at the last checkpoint without any parameters. You can run more than one pvmove command at a time, provided that data is moved from different source physical volumes.

Syntax format: pvmove [parameters] [source physical volume] [target physical volume]

Common parameters:

Reference example

Move all physical extents on the physical volume / dev/sda5:

[root@linuxcool ~] # pvmove / dev/sda5

Move the physical extent on the source physical volume / dev/sda5 to the physical volume / dev/sda6:

[root@linuxcool ~] # pvmove / dev/sda5 / dev/sda6

Move the physical disk area 1000001999 on the source physical volume / dev/sda5 to the physical volume / dev/sda6:

[root@linuxcool] # pvmove / dev/sda5:1000-1999 / dev/sda6

Abort any movement in progress:

[root@linuxcool ~] # pvmove-- so much for abort about using linux's pvmove command to move the physical disk. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
