<div>Thank you for your response.</div>

In our scenario we're limited to a single PV on the LVM and
while online does work it takes a long time for the pvmove to
complete from say 2TB to a 3TB PV.

<div>We're trying the offline in hopes that it would speed
things up a lot.</div>

<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
<resource> 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>
