Hi everyone,
Im trying to mount my volume on my VM but im encountering several problems
1) Using nfs mount to mount my gluster volume, i am able to mount normally,
but when i access executables stored on my gluster volume, the process
hangs and i have to cancel it. Once i cancel the process, the mount point
is no longer accessible and im unable to view any files on my mount point

2) using gluster-client (same version as server 3.6.2 ) to mount my gluster
volume , im getting the following messages in the gluster log.

  1: volume gfsvolume-client-0

I have deployed gluster successfully on my physical machines and my network
is fine. I used the exact same steps to install the gluster client on my VM
and my physical machines.  Some info you may find helpful in narrowing down
the error is as below:

-My physical machines are fine and show no error messages in log.
-I am able to ssh into the machine so it is not a network problem.
-there are no firewall rules on the gluster server and client .
-I have done modprobe fuse successfully.
- NFS is installed on all machines.
- gluster versions are same on all machines
- gluster volume status shows all processes are online
- gluster status client does not show my client machine
-server can ping to client and client can ping the server
-i tried restarting rpcbind but it didnt fix my problem

If there is anything else you would need to help me fix this , please do
let me know and ill pass the info on to you .

Eid Mubarak to all those who are celebrating and thank you in advance for
your assistance.

Thanks,
Kaamesh
