Yes I realise that :)<br><br>
I was under the impression that heal info lists the files that are
the src of the heal, e.g all the files on vna & vnb. <br><br>
vng which is blank would only be receiving files.<br><br><blockquote cite="mid:1689369024.6494444.1453119887191.JavaMail.zimbra@redhat.com"><div>Yes, there is a bug report for this @ <a class="moz-txt-link-freetext" href="https://bugzilla.redhat.com/show_bug.cgi?id=1112158" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=1112158</a>.</div><div>The workaround, like you yourself figured, is to run the

Will do.<br><br>
