<p dir="ltr">You can try to run a ncat from gfs3:</p>
<p dir="ltr">ncat -z -v gfs1 49152<br>
ncat -z -v gfs2 49152</p>
<p dir="ltr">If ncat fails to connect -> it's definately a firewall.</p>

<p>I don't see a "Connected to gvol0-client-1" in the log. Perhaps
a firewall issue like the last time? Even in the earlier add-brick
log from the other email thread, connection to the 2nd brick was
not established.</p>

<div>Hi Ravi and Joe,</div>

<div>The command "gluster volume status gvol0" shows all 3
nodes as being online, even on gfs3 as below. I've
attached the glfsheal-gvol0.log, in which I can't see
anything like a connection error. Would you have any
further suggestions? Thank you.</div>
