This is all. It just happens on boot upon mount. It gives these errors
until it finally connects after a few seconds. If I do no operation, it
will not work until I do one and get these errors.

iptables rules are few (around 20) and the average response time is
around 100ms (we have an internal DNS server that serves for all
internal machines.

Where exactly is the client volume spec file? Can you give me the path?

I sure can disable iptables.

What I did to have a dirty/ugly workaround for now is to create an init
script that performs an `ls` to the mount point. At that point I get the
error 'Transport endpoint is not connected', I make the init script wait
10 seconds and when the service that requires the glusterfs partition to
be online, it gets it working.

My diagnose on this is that until an operation is performed, the
connection to the server does not actually get established. After
performing any operation on the mount point, it returns 'Transport
endpoint is not connected' error and a few seconds later everything is
working fine. Weird.
