[Gluster-users] Unable to mount (glusterfs-fuse: 2: LOOKUP() error)

Why have you created a "disperse" volume with "0" redundancy? 
There is no sense of creating this configuration of disperse volume. However, it should be noted why cli allowed it at all. 
I tried your config with the latest version and I also was not able to mount the volume. 
In my case I could see the error message in logs which clearly shows that - 

[2016-08-08 04:07:50.261561] I [MSGID: 101190] [event-epoll.c:628:event_dispatch_epoll_worker] 0-epoll: Started thread with index 1 
[2016-08-08 04:07:50.271330] E [MSGID: 122051] [ec.c:63:ec_parse_options] 0-test-disperse-0: Invalid redundancy (must be between 1 and 3) [Invalid argument] 
[2016-08-08 04:07:50.271354] E [MSGID: 122052] [ec.c:599:init] 0-test-disperse-0: Failed to parse xlator options [Invalid argument] 

I did not see any such message in logs provided by you. 
I think you should consider using the latest version of gluster and also use a config which actually serves the purpose of disperse volume.

Glusterfs Ver 3.7.6 
Dispese vol 

Volume info says, vol is started. 
Vol status says , all bricks are online. But still unable to mount due to below error . 

[2016-08-05 07:33:37.192970] W [fuse-bridge.c:758:fuse_attr_cbk] 0-glusterfs-fuse: 2: LOOKUP() / => -1 (Transport endpoint is not connected).
