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 ...

host(a.b.c.d) I got,
Host a.b.c.d.in-addr.arpa. not found: 3(NXDOMAIN)

a.b.c.d stands for the ip address of my client.

Wild guess -

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.

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

In the gluster nodes, I could ping the clients using the hostnames. So, DNS wouldn't be the root cause.

the clients could also resolve the hostnames (ping is ok)

How is your DNS setting?

Could your client resolve the hostname?

I tried to set auth.allow using hostnames (not IPs) of clients
such as

gluster volume set VOLUME auth.allow hostname1,hostname2,hostname3

But the clients could not mount the volume

If I use IPs, it defintely works.

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.

Any comments?
