<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am having issues using the vmware 10Gb virtual adapter with
vmxnet driver and drbd. When I go to sync the resources, the sync will
always stall at some point. I have confirmed that the vmxnet driver is
the culprit, as I have no issues using the e1000 NIC and driver on the same VMs.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My setup is this:<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I add a vmxnet3 virtual adapter to the VMs and start
drbd, it begins syncing and then quickly will stall. The behavior is
identical when I map the virtual NIC to either the Emulex 10Gb adapter on the ESXi
host, or the Broadcom 1Gb adapter. So I know its not the physical link that’s
the issue.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Conversely when I add the e1000 NIC to the VMs and start
drbd, everything syncs fine with no issues, and again this is the same no
matter what physical link I connect the VMs to.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I installed vmware tools and verified it loaded the vmxnet3
module successfully.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have looked in the messages log but haven’t found
anything, is there another log I should be reviewing?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance for any insight into this.<o:p></o:p></p>
