Gluster users - Dec 2014 - 3.5.3 NFS locking issues

Hi,

I am using gluster 3.5.3 via packages from the gluster repository and am seeing
some incidents where applications (mainly PHP/perl) when accessing  NFS shared
gluster filestore are having timeout issues when a flock() system call is used.

It occurs to me that the obvious thing here is to change my NFS mount options to
forcibly tell the NFS client not to use locking and presumably to let the
Gluster service deal with this at the server end, but does raise the following
questions:

1. is forcibly disabling client side locking the 'right' thing to do?
2. if the above is true then why does the gluster documentation not recommend
this? (this is not intended as snarky dig - honest)

Thanks

Paul
