From what i remember i tried and the following
mount -t glusterfs --direct-io-mode=off
mount -t glusterfs -o direct-io-mode=off
mount -t glusterfs --direct-io-mode=disable
mount -t glusterfs -o direct-io-mode=disable
mount -t glusterfs -o --direct-io-mode=disable
and others but didn't managed to solve the problem we had. Sorry but
can't try it again to be 100% sure for the result of all the above since
we removed gluster3.1.0 from theses 4 servers that we were testing :(
Maybe the problem was somewhere else to the systems (centos5.5) since
3.0.5 that installed after that wasn't working right with xen and tap
for disk files either, while 3.0.5 on debian servers is working just
fine with xen and tap.
Probably has to do with the different kernel version as i mentioned to
my previous mail (lenny has xen 2.6.26 and centos 2.6.18).
The other difference between the two setups was that on debian servers
downloaded source and on centos servers downloaded the rpms for centos.
Thanks for your interest and your very nice software and sorry that
can't give more details that maybe could help others too but as i wrote
we removed from the centos (working fine on debian).
It's a bit difficult time these days for more retries :( , so will try
again but later on centos 6 and new xen kernel.
Thank you very much,
Kostas

in 3.1.x the options --disable-direct-io-mode and --enable-direct-io-mode are
replaced by --direct-io-mode=[off/on]. So, I was interested in knowing whether you
used the option --disable-direct-io-mode or --direct-io-mode.> From your
previous mail, it seems you are trying to use --disable-direct-io-mode (which is
not supported in 3.1.x). Hence please use --direct-io-mode and let us know whether
the issue still persists.
regards,

Hello,
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

Hi Kostas,
Is --direct-io-mode=off not working for you?
regards,
Raghavendra.

Subject: [Gluster-users] glusterfs 3.1.0 disable-io-mode
Hello,
I'm trying gluster 3.1.0 in conjunction with XEN on centos 5.5.
I have problem installing a vm cause installation hangs. Searched the
net and found that for xen to work in previous gluster versions thay had
to disable direct io mode.
glusterfs says that don't recognize --disable-direct-io-mode. I tried
several syntax with --diasble-direct-io-mode , direct-io-mode=disable,
direct-io-mode=off , and in different positions of the mount command
(mount -t glusterfs -o<opt> ...... , mount -o<xxx> -t glusterfs
xxxx:/xxx /xxx , etc)
Thanks in advance
Kostas
