Small correction in the file I provided earlier. pmap_set returns 0 in
case of failure.

The error you got shows that portmap registration of mountd service
failed. You could start rpcbind in debug mode to print error messages on
the console
1) create/edit '/etc/sysconfig/rpcbind' with following contents.
#
# Optional arguments passed to rpcbind. See rpcbind(8)
RPCBIND_ARGS="-d"
2) restart rpcbind service. Now instead of starting in daemon mode,
rpcbind now prints syslog messages and waits on the console.
3) Now on another console, either restart glusterd or I have written
small c program to register mountd service with portmap (attached). You
could run it and look at below syslog messages printed by rpcbind services.

That's all I could think of. CCin Niels. He may be able to provide more
information on how to debug this issue.
Thanks,

For the protocol, I've reinstalled, restarted, anything I could, I've
checked anything I could find in the google and this doesn't work.
Please, lets move on with something more sophisticated than restart
glusterfs... I would not contact you if I had not tried to restart it
dozen of time.
Do you have any debugging to see what is really happening?
2015-09-15 1:55 GMT+08:00 Soumya Koduri <skoduri@xxxxxxxxxx
<mailto:skoduri@xxxxxxxxxx>>:
Could you try
* disabling iptables (& firewalld if enabled)
* restart rpcbind service
* restart glusterd
If this doesn't work, (mentioned in one of the forums)
Add below line in '/etc/hosts.allow' file.
ALL: 127.0.0.1 : ALLOW
Restart rpcbind and glusterd services.
Thanks,
Soumya
