Hi,

I am using Openstack Wallaby release with OVN on Ubuntu 20.04. My environment consists of 2 compute nodes and 1 controller node. ovs-vswitchd (Open vSwitch) 2.15.0 Ubuntu Kernel Version: 5.4.0-88-generic compute node1 172.16.30.1 compute node2 172.16.30.3 controller/Network node/Primary ovs-db IP 172.16.30.46 backup ovs-db 172.16.30.47

I added another node for backup ovs-db server (172.16.30.47 ) and installed openvswitch-ovn and networking-ovn packages on it for backup ovs-db server and using Pacemaker to manage the ovn-northd(Open vSwitch) service between primary and backup ovs-db server active/passive HA mode. Pacemaker cluster is successful and after creating a pacemaker cluster, I am using the following commands to create one active and one backup server for OVN databases.

$ pcs resource create ovndb_servers ocf:ovn:ovndb-servers \ master_ip=172.16.30.46 \ ovn_ctl=<path of the ovn-ctl script> \ op monitor interval="10s" \ op monitor role=Master interval="15s"

But i am getting below error:

Error: Agent 'ocf:ovn:ovndb-servers' is not installed or does not provide valid metadata: Metadata query for ocf:ovn:ovndb-servers failed: Input/output error, use --force to override

I would really appreciate any input in this regard.

Best regards, Faisal Sheikh
