Re: Unable to mount (glusterfs-fuse: 2: LOOKUP() error)

Hi,

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.

Please provide the output of "gluster vol info" and "gluster vol status"  of the concerned volume.

Also, please provide mount logs present in /var/log/gluster with name <mount point>.log

What command are you executing while mouting, please mention exact command.
