<div dir="auto">You could also try xfsdump and xfsrestore if you brick filesystem is xfs and the destination disk can be attached locally? This will be much faster.<div dir="auto"><br></div><div dir="auto">Regards,</div><div dir="auto">Poornima</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Apr 2, 2019, 12:05 AM Tom Fite <<a href="mailto:tomfite@gmail.com" target="_blank" rel="noreferrer">tomfite@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr">Hi all,<div><br></div><div>I have a very large (65 TB) brick in a replica 2 volume that needs to be re-copied from scratch.
