<p class="MsoNormal">Hello Everyone, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<pre>We are setting up an 8.4 cluster (elrepo RPMs -- <span style="color:black"><a href="http://mirror.symnds.com/distributions/elrepo/elrepo/el6/x86_64/RPMS/drbd84-utils-8.4.4-2.el6.elrepo.x86_64.rpm">drbd84-utils-8.4.4-2.el6.elrepo.x86_64.rpm</a> a</span>nd <span style="color:black"><a href="http://mirror.symnds.com/distributions/elrepo/elrepo/el6/x86_64/RPMS/kmod-drbd84-8.4.4-1.el6.elrepo.x86_64.rpm">kmod-drbd84-8.4.4-1.el6.elrepo.x86_64.rpm</a></span>) on RHEL 6. <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I have two SuperMicro storage boxes with 2 x 4 core Xeons, 48GB RAM, LSI 9280-24i-4e cards, 2 x 512GB SSDs set up as a RAID1 CacheCade, 21 x 2TB WD RE4 drives set up in a 36TB RAID50, and 10GbE over fiber connecting the two machines. DRBD volume is on top of an LVM logical volume. <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>For some reason, a few hours after starting the initial sync, network activity between the boxes dies down and DRBD shows that the nodes are syncing but the numbers are not changing. <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I don’t see any errors anywhere in the logs. <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I am running the same RPMs, same version of RHEL, and same kernel, and a largely similar (smaller) setup on other systems and do not see the same problem. <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Thanks,<o:p></o:p></pre>
