Folks,

I am dealing with a very strange DHCP issue because of the priority of ha_chassis. I have the following ha_chassis group and I want os-chn-gen-comp-001 and os-chn-gen-comp-002 to always service DHCP for sriov interface.

I have used following command to give them high priority

$ ovn-nbctl --no-leader-only set ha_chassis 97077f76-46ae-4e15-9502-24fdb4ad0214 priority=32767

But suddenly today something happened and all priority got reset causing small outage and cause all sriov VM started looking IP address. Solution was I have again set high priority again by hand to fix it.. How do I make priority permanently so it will never reset again.

$ (ovn-nb-db)[root@os-chn-ctrl01 /]# ovn-nbctl --no-leader-only list HA_Chassis 784ec6e9-9af8-45c6-86e0-75ae7ccf9278 7fa04343-4471-4707-b5e9-23bd7f29ca6e 97077f76-46ae-4e15-9502-24fdb4ad0214 c75de7ab-b346-4aa5-886b-31b0fd12401e dd6ce2d4-9746-4429-862a-e78750bb4909
