I remember that i tried that to with mount -t glusterfs and i was 
getting error that glustrerfs don't understand --disable-direct-io-mode 
(wasn't writing disable but probably was translating the command to that) .
We removed gluster 3.1 and install gluster 3.0.5 from the centos rpms 
where the parameter gave no error but we continue having problems with 
xen and paravirtualized with tap "disks" . We installed the patched fuse 
and didn't solved our problem. We get to the conclusion that maybe 
problem was that the kernel on these machines was 2.6.18-194.el5xen 
(centos 5.5). On debian machines that xen  kernel was 2.6.26 was working 
with tap, but the machines we wanted to use are dell that debian is not 
installing. We gonna have a look for testing with other clustered file 
system on these machines and check again with glusterfs when we are 
going to install centos6 and make use of new glusterfs version.

Thanks for your replies
