NFS active/active cluster with gluster and NFS-ganesha, I can create dirs, but not files!

Following this fantastic guide I finally setup an active working active/active nfs4 cluster.
The setup is not too difficult: two servers with ganesha+glusterfs other two with haproxy and keepalived.
The cluster works fine, from one client I have mount the nfs share called "nfshare" without problem

Code:

mount -t nfs4

nfsserver:/nfsshare on /mnt type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.2.0.170,local_lock=none,addr=10.2.0.7)

I have created some dirs on mnt and works perfect(there are replicated on nfsgluster servers). I have also rebooted for testing the nfs server one or two, and after a very little downtime (2 seconds) the connection is up and working.
The problem is..mkdir works, but every file operation(dd,cp,touch) fails(stuck,freeze until ctrl+c is pressed).

On both the nfs servers and keepalived servers there is no problem with selinux

Code:

grep -i denied /var/log/audit/audit.log

What can be?Why mkdir works and file operation not?

Solution found, ganesha was misconfigured, I have forgot to add the ports for services.

Here is the scenario... NFS share that is accessed every few minutes by approx 70 systems (AIX 5.3/6.1). Filesystem space is being eaten up rapidly according to df however du numbers really never change. lsof and fuser cannot see any unlinked files on either the NFS server or remote clients. ...
