The user provided some logs and output from commands they've run. + +Looking at the log message: it says ovs-vsctl encountered a constraint violation when trying to create a Manager row. The issue is that two rows have the same target value for the "Manager" table, which isn't allowed because of the unique index on the "target" column. + +Hmm, the error mentions two UUIDs—9f27ddee... and ccf0e097.... So, it looks like one row was inserted by this transaction, and another already existed. That suggests that someone tried to add a Manager entry with the same target as an existing one. + +In Neutron's Open vSwitch agent, each compute node (like awrep1, awrep2, etc.) should have its own OVS instance managed by a separate Manager in ovsdb. If two agents are trying to create Managers with the same target, that would cause this error. + +Wait, looking at the agent-list output: there are multiple Open vSwitch agents running on different hosts (awrep1, awrep2, awrep3, awrep4). Each of these should connect to their own OVSDB instance. So why is there a conflict in the target? + +Maybe the issue is that all these agents are trying to connect to the same OVSDB server or using the same port? Or perhaps one of them isn't configured correctly and is trying to use the same Manager target as another. + +Another thought: Could it be related to Neutron's setup, where each agent should have a unique connection to OVSDB. If they're all pointing to the same place, that would cause duplication. + +I should check if the agents are properly configured with their own settings. For example, in neutron.conf or ovs-agent.conf, maybe there's an issue where multiple agents are using the same ptcp:6640 address. + +Also, perhaps the OVSDB server is running on a single host, but the agents are trying to connect to it from different computes. If the OVSDB server isn't configured correctly, or if there's a misconfiguration in how each agent connects, that could cause this duplication. + +I should look into each Open vSwitch agent's configuration. Maybe they're all pointing to 127.0.0.1:6640, which is causing them to try and create the same Manager entry. + +Another angle: If one of the agents was restarted or started multiple times, maybe it tried to add a duplicate Manager entry before the previous transaction was complete. But that's less likely since each agent should be independent. + +I think the key here is ensuring that each Open vSwitch agent connects to its own OVSDB instance or that their ptcp targets are unique if they're connecting to the same server but different ports. + +Looking at the command in the log: ['ovs-vsctl', '--timeout=10', '--oneline', '--format=json', '--', '--id=@manager', 'create', 'Manager', 'target="ptcp:6640:127.0.0.1"', ...]. So each agent is trying to create a Manager with the same target string. + +Therefore, the problem is that multiple agents are trying to connect to the same OVSDB instance via the same ptcp address and port. Each should have their own unique target or be pointing to different instances. + +To fix this, I need to make sure each Open vSwitch agent connects to its own OVSDB server or that they're configured correctly so that each uses a unique identifier when connecting as a Manager. +</think> + +The error arises because multiple Neutron Open vSwitch agents are attempting to create identical Manager entries in the OVSDB, causing a constraint violation. Each agent should connect uniquely to an OVSDB instance. + +**Step-by-Step Explanation:** + +1. **Identify the Cause**: The error occurs when two agents try to add Managers with the same target value (ptcp:6640:127.0.0.1), violating the unique index on the "target" column in the Manager table. + +2. **Understand Neutron's Setup**: Each compute node should have its own OVSDB instance managed by a distinct Open vSwitch agent. Thus, each agent must connect to a separate or correctly configured OVSDB target. + +3. **Check Agent Configuration**: Ensure that each Open vSwitch agent is pointing to the correct OVSDB server. If they're all connecting to 127.0.0.1:6640, this causes duplication. + +4. **Verify Neutron Configurations**: Look into `neutron.conf` or `ovs-agent.conf` for any settings that might cause multiple agents to connect to the same OVSDB instance. + +5. **Ensure Unique Targets**: Each agent should have a unique target address. If they're all using ptcp:6640, consider if this is intentional and adjust configurations to prevent duplicates. + +**Solution:** + +- Modify each Open vSwitch agent's configuration to point to distinct OVSDB instances or use different ports/target addresses. +- Ensure that the OVSDB server is properly set up for each compute node so agents don't interfere with each other's Manager entries. \ No newline at end of file |
