<p><font size="2">Dear Team,<br>
I have installed and configured gluster in one server and client.<br>
one time it was worked fine, again later it is not working.<br>
my configuration files.<br>
server<br>
[root@rhel2 ~]# cat /etc/glusterfs/glusterfs-server.vol<br>
volume rhel2<br>
type storage/posix # POSIX FS translator<br>
option directory /opt # Export this directory<br>
end-volume<br>
<br>
volume rhel2<br>
type protocol/server<br>
option transport-type tcp/server # For TCP/IP transport<br>
option client-volume-filename /etc/glusterfs/glusterfs-client.vol<br>
subvolumes export test<br>
option auth.ip.rhel2.allow * # Allow access to "brick" volume<br>
end-volume</font></p></div></blockquote><div>* Both xlators (protocol/server and storage/posix) are named as rhel2. Each translator instance should be given a different name.<br> <br>* protocol/server lists "export" as one of its subvolumes, which is not present in the specfile. Try removing it if you dont need it.<br>
<br>* server should have "option client-volume-specfile <glusterfs-volume-specification-file>" or a client-specfile should be present as <glusterfs-install-prefix>/etc/glusterfs-client.vol<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Apart from these i have few doubts,<br>
1)In our website it told that gluster there is no single point of failure.<br>
But as per configuration point of view it is like server and client model so if server fails<br>
client cannot able to mount.</font></p></div></blockquote><div>No single point of failure when glusterfs is run in clustered mode. What it exactly means that there is nothing like a single metadata server, failure of which renders cluster not operational (Though currently unify has a limitation in the form of namespace, which will be fixed in future releases). <br>

2)In server how can i confirm whether server was exported or not where as in NFS we have command to check showmount.</font></p></div></blockquote><div>There is no tool currently which tell the directories exported by server. But this can be found out by checking logfiles of server. <br>
