russellbarslanq: The OVN databases (ovsdb-server) support active-passive HA (a primary and N backups).  We're currently using pacemaker to manage that.12:11
russellbarslanq: we also use pacemaker to manage HA for ovn-northd, which runs once, along side the OVN master databases12:12

arslanqrussellb: Thanks12:37
russellbarslanq: Ben Pfaff is working on ovsdb clustering, which will let us run the OVN databases in an active-active HA mode.12:39
arslanqrussellb: Thanks i'll try ovn in HA and will give feedback12:42
numansarslanq, if you are confortable with puppet, you can have a look at it - https://review.openstack.org/#/c/372274/12:43
numanselse you can use pcs commands to create the resources12:43
russellbarslanq: also, see the "HA for OVN DB servers using pacemaker" at the bottom of this page http://docs.openvswitch.org/en/latest/topics/integration/12:44
arslanqrusselb: numans: Thanks this is really very helpful for me12:47

russellbyou're welcome12:47

numansrussellb, in the syslogs, i see strange prints like - Mar 21 02:35:13 ubuntu-xenial-osic-cloud1-s3500-7975146 systemd-udevd[27374]: Could not generate persistent MAC address for tapf33e2e50-da: No such file or director12:58
russellbweird12:58
numansrussellb,  probably need to test with ubuntu trusty i guess12:59
numansrussellb, oops its xenial. :)12:59

numansrussellb, no luck with ubuntu xenial -Its working fine in my setup.14:10
russellbnumans: :-/14:10
numansrussellb, only option left is debug in CI with prints :)14:11
numansrussellb, may be ovs folks know why OFPBMC_BAD_PREREQ is sent when ovn-controller resumes the dhcp packet14:12
russellba bunch of prints in the ovs code where that gets returned would probably be my next step heh14:14
numansyeah. that's what i am planning to14:14

russellbnumans: if needed, you could also join #openstack-infra and ask if they could hold a VM where the failure is reproduced so that you can log in and look14:58
