Means you'd better use IP instead of host name, or you have to ask
your DNS administrator to setup reverse DNS (PTR record) for those
IPs, which may involve your upstream ISP, or even more complicated
than that ...<br>

How about DNS revert delegation? Try "host <IP>"
to see if it can be mapped back to "hostname1" then
there should be something wrong, otherwise you have DNS
problem.<br>

<br>
P.S. I guessed because I believe whenever a connection
comes in, the server does not know anything other than
IP and port.<br>

<div>I tried to set auth.allow
using hostnames (not IPs) of
clients <br>
such as <br>
</div>
gluster volume set VOLUME
auth.allow
hostname1,hostname2,hostname3<br>
<br>
But the clients could not mount
the volume<br>
</div>
If I use IPs, it defintely works.<br>
</div>
But for my clients use DHCP, so I
don't think using IPs is a good idea
for they could be changed but
hostnames of them wouldn't. <br>
