I have bond0 on em1 and em2 and then bondo.65, bond0.68, bond0.167 vlans defined for the VMs I get these warnings Message:Host ov300 has network interface which exceeded the defined threshold [95%] (em1: transmit rate[98%], receive rate [0%]) when actually I think the 3 VMs running on this host generate few MB/s of traffic I applied the changes to the 3 hosts. I notice that due to dependencies it is sufficient to restart supervdsmd and then also vdsmd will be automatically restarted, correct? In my case for each of the 3 hosts, after restarting supervdsmd I got messages like these, but without impacts on runnign VMs VDSM ov300 command GetStatsAsyncVDS failed: Broken pipe 9/4/18 9:07:52 AM Host ov300 is not responding. It will stay in Connecting state for a grace period of 61 seconds and after that an attempt to fence the host will be issued. 9/4/18 9:07:52 AM No faulty multipath paths on host ov300 9/4/18 9:07:58 AM Executing power management status on Host ov300 using Proxy Host ov200 and Fence Agent ipmilan:10.10.193.103. 9/4/18 9:07:58 AM Status of host ov300 was set to Up. 9/4/18 9:07:58 AM Host ov300 power management was verified successfully. 9/4/18 9:07:58 AM Please note that when doing on SPM host you could also get these: VDSM ov301 command SpmStatusVDS failed: Broken pipe 9/4/18 9:10:00 AM Host ov301 is not responding. It will stay in Connecting state for a grace period of 81 seconds and after that an attempt to fence the host will be issued. 9/4/18 9:10:00 AM Invalid status on Data Center MYDC. Setting Data Center status to Non Responsive (On host ov301, Error: Network error during communication with the Host.). 9/4/18 9:10:00 AM with reassignment of SPM role: VDSM command GetStoragePoolInfoVDS failed: Heartbeat exceeded 9/4/18 9:10:12 AM Storage Pool Manager runs on Host ov200 (Address: ov200), Data Center MYDC. 9/4/18 9:10:14 AM Probably safer to manually move the SPM before restarting supervdsmd on that host. Let's see this evening if I will get any message about thresholds. BTW: one question. I see in the code iface.Type.NIC and now also iface.Type.BOND. Don't you think that you should manage also the network teaming option available in RH EL 7, as described here: https://access.redhat.com/documentation/en-us/red_hat_ enterprise_linux/7/html/networking_guide/ch-configure_network_teaming ? This only if it is supported to use the new network teaming implementation in oVirt, and I'm not sure about it...
