<p dir="ltr">I just reminded about your previous e-mail which left me with the impression that old volumes need that.<br />
This is the one 1 mean:</p>

However, different processes would behave differently. In earlier releases, all nodes would crawl the bricks and update the directory layouts. However, only one node in each replica/disperse set would actually migrate files,so the rebalance status would only show one node doing any "work" (scanning, rebalancing etc). However, this one node will process all the files in its replica sets. Rerunning rebalance on other nodes would make no difference as it will always be the same node that ends up migrating files.</div><div><div>So for instance, for a replicate volume with server1:/brick1, server2:/brick2 and server3:/brick3 in that order, only the rebalance process on server1 would migrate files. In newer releases, all 3 nodes would migrate files.</div><div><br /></div></div><div>The rebalance status does not capture the directory operations of fixing layouts which is why it looks like the other nodes are not doing anything.<br /></div><div><br /></div><div>Hope this helps.<br /></div><div><br /></div><div>Regards,</div><div>Nithya</div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb( 204 , 204 , 204 );padding-left:1ex"><div align="left"><p dir="ltr">behaviour. <br />
