Hello, 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.
My setup is this: - ESXi 4.1 on new HP DL 380 G7 servers - Onboard Broadcom NC382i gigbit adapter - Add on Emulex OneConnect 10Gb SFP adapter - Two identical fedora 13 VMs setup with drbd version 8.3.7 installed - One SFP+ cable running direct between the two 10Gb NICs on each server, no switch. - One 1Gb CAT6 cable running direct between two 1Gb NICs on each server, no switch. 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. 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. I installed vmware tools and verified it loaded the vmxnet3 module successfully. I have looked in the messages log but haven't found anything, is there another log I should be reviewing? Thanks in advance for any insight into this. Sean
