<p class="MsoNormal"><span style="font-size:11.0pt">We need to remove a server node from our configuration (distributed volume). There is more than enough space on the remaining bricks to accept the data attached to the failing server; we didn’t know if
one process or the other would be significantly faster. We know shrinking the volume (remove-brick) rebalances as it moves the data; so moving 506G resuled in the rebalancing of 1.8T and took considerable time.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Reading the documentation, it seems that replacing a brick is simplying introducing an empty brick to accept the displaced data, but it is the exact same process: remove-brick.

<p class="MsoNormal"><span style="font-size:11.0pt">Is there anyway to migrate the data without rebalancing at the same time and then rebalancing once all data has been moved? I know that is not ideal, but it would allow us to remove the problem server much
quicker and resume production while rebalancing.<u></u><u></u></span></p>
