Hi,
Thank you I haven't seen this article. But we use Centos 5 and
ext3 on every machine.

Hi,
We have a problem with glusterFS. We are using it on Centos 5
machine with OpenVZ kernel. Gluster daemon and gluster clients
run on the host, not in the container. Recently we noticed a
problem when we upgraded the OpenVZ kernel. After the upgrade
there are strange errors in case of accessing the gluster
volume. There are a few folders that can't be seen with 'ls' but
if you give the whole path you can access the files in the
folder. If there is a folder with files in it and you type 'ls'
it hangs and only can be stopped with 'kill -9'.
We are using glusterfs 3.2.5 but we have tried with 3.2.7 and
the same happened.
With kernel version: 2.6.18-308.el5.028stab099.3 -- there were
no errors.
With kernel version: 2.6.18-348.3.1.el5.028stab106.2 -- it has
the above mentioned errors
Unfortunately we don't have any information about the other
kernels between the two versions. We can reproduce the errors in
production and development environments. We created a new volume
on our own test computers but we cannot reproduce the bugs. If
we mount the development gluster volume on the test computers
which are running the 2.6.18-348.3.1.el5.028stab106.2 OVZ kernel
we cannot reproduce the bug. That's why we think the gluster
clients work with the new kernel but the gluster daemon doesn't.
It's the ext4 problem:

Backported to el5 as of 2.6.18-326.el5
