Public bug reported: == Comment: #0 - Andrew Thorstensen - 2016-11-17 09:50:25 ==
---Problem Description--- Using Ubuntu 16.04 on ppc64le, we are building a 'neutron network node' using the VRRP configuration (built on keepalived). Information on this OpenStack configuration can be found here: https://wiki.openstack.org/wiki/Neutron/L3_High_Availability_VRRP When we run, the configuration is failing to apply via keepalived. The logs post the following: Nov 17 02:58:31 p8test-lp1 Keepalived_vrrp[54542]: VRRP is trying to assign VIP to unknown qr-a5f5ba96-52 interface !!! go out and fix your conf !!! However, the device DOES exist. But the keepalived config just doesn't always deploy it. ii keepalived 1:1.2.19-1 ppc64el Failover and monitoring daemon for LVS clusters This configuration sometimes works, but does sometimes fail on Ubuntu 16.04.1 ---uname output--- Linux p8test-lp1 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:38:24 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux ---Additional Hardware Info--- This is a Power8 system with Ubuntu 16.04.1 installed. Though we see no indication that this is specific to Power. Machine Type = S822L Machine Type = 8286-42A ---Steps to Reproduce--- Install openstack. Run the network node in a VRRP HA configuration. Create a router and assign a global IP. == Comment: #5 - David J. Wilder - 2016-11-17 15:58:04 == The problem is fixed in this upstream commit: https://github.com/acassen/keepalived/commit/9f327bbf3e86def1055a106eda0633638bda0345 On systems with a page size larger than 4096 keepalived may report: "Netlink: error: message truncated" messages This error was reported on a ppc64le in an OpenStack/Nutron environment. Ppc64le is using a 64k pages size. I found that keepalived's netlink recvmsg buffer was too small causing messages to be truncated. The size of the read buffer for the netlink socket should be based on page size however, it should not exceed 8192. See the comment in the patch. I tested the fix by creating 100 veth interfaces and verifying the errors did not return.
