    <p>I am pretty sure you could just allocate space from the new PV to
      the existing LV, that way, the LV will span both the old PV and
      the new PV. If you are using SSD storage, then this won't matter,
      if you are using spinning disks, then you might want to
      specifically allocate blocks from the new PV in the physical
      position where it will end up when finished, and then when you do
      the pvmove later, it will be contiguous with the old and new data
      all on the new PV.</p>
    <p>Does that make sense?</p>

            <p>Sorry, I still don't understand. If you have a single PV,
              what are you using pvmove for?</p>
            <p>In my scenario, I use lvextend and then drbdadm resize.</p>
            <p>Or do you mean you are adding additional physical devices
              with larger capacity, and then using pvmove to relocate to
              the new device, and then using lvextend to increase the
              size, and then drbdadm resize? and instead you are
              planning to drbdadm down &lt;resource&gt; and then fiddle
              with the underlying devices, and then drbdadm up ?</p>
            <p>Is the problem that pvmove takes a long time to complete,
              or that it affects performance too much during the move?
              Just curious...</p>
