<pre>We had issues with ext4 about a bit less than a year ago, at that time I
upgraded the servers to CentOS-6.2. But that gave us large problems
(more than slow reads). Since I didn't want to reformat the disks at
that time (and switch to XFS) I went back to CentOS-5.5 (which we had
used before). On some link (think it was
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=713546">https://bugzilla.redhat.com/show_bug.cgi?id=713546</a> but can't seem to
reach that now) it was stated that the ext4-issue was present even on
later versions of CentOS-5 (I _think_ 5.8 was affected).
Are there hope that the "ext4-issue" will be solved in later
kernels/versions of gluster? If not, it seems one is eventually forced
to switch to XFS.

Dear All-<br>
Could someone please confirm whether or not the ext4-issue affects
any Centos-5 kernels? All the information and correspondence I have
seen so far has mentioned CentOS 6.3.<br>
