My starving count was pretty high. I maxed out my al-extents and will see if that helps. Thanks.<br><br><div class="gmail_quote">On Fri, Jun 22, 2012 at 4:22 AM, Andreas Kurz <span dir="ltr"><<a href="mailto:andreas@hastexo.com" target="_blank">andreas@hastexo.com</a>></span> wrote:<br>

</div>You checked that you are not running out of activity log extents for the<br>
stacked resource?<br>
<br>
Do an: echo 1 >/sys/module/drbd/parameters/proc_details<br>
<br>
... and have a look at "starving" counter in /proc/drbd ... should<br>
ideally be 0 and definitely not increasing regularly. If it does,<br>
increase the al-extents value for the stacked resource (max is 3833 in<br>
drbd 8.3 ... IIRC)<br>
<br>
