--- Comment #1 from Csaba Henk <csaba at redhat.com> ---
Further notes about reproduction:

- In the bug descriptpion the mount options were listed *incorrectly*. They
should be: -oentry_timeout=0,gid_timeout=0
- It's sufficient to use a single brick volume
- The volfile can be stripped down as follows:

volume moz-client-0
    type protocol/client
#   Following settings were just left at default
    option send-gids true
    option transport.socket.keepalive-count 9
    option transport.socket.keepalive-interval 2
    option transport.socket.keepalive-time 20
    option transport.tcp-user-timeout 0
    option password <PASSWORD> 
    option username <USERNAME>
    option transport.address-family inet
    option transport-type tcp
    option remote-subvolume /bricks/moz0
    option remote-host <HOST> 
    option ping-timeout 42
end-volume

volume moz-md-cache
    type performance/md-cache
    subvolumes moz-client-0
end-volume

volume moz
    type performance/io-threads
    subvolumes moz-md-cache
end-volume

- So the glusterfs commandline for a manually created volfile can be like this: 

# glusterfs  --entry-timeout=0 --gid-timeout=0 --volfile=<FILE> <MOUNTPOINT>
