<div dir="ltr"><div>For what it's worth, I just updated some CentOS 7 servers from GlusterFS 3.12.1 to 3.12.4 and hit this bug. Did the patch make it into 3.12.4? I had to use Mike Hulsman's script to check the daemon port against the port in the volume's brick info, update the port, and restart glusterd on each node. Luckily I only have four servers! Hoping I don't have to do this every time I reboot!<br><br></div>Regards,<br></div><br><div class="gmail_quote"><div dir="ltr">On Sat, Dec 2, 2017 at 5:23 PM Atin Mukherjee <<a href="mailto:amukherj@redhat.com">amukherj@redhat.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div><div class="gmail_quote"><div dir="auto">On Sat, 2 Dec 2017 at 19:29, Jo Goossens <<a href="mailto:jo.goossens@hosted-power.com" target="_blank">jo.goossens@hosted-power.com</a>> wrote:<br></div></div></div></div><div><div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><u></u>
