URL: https://github.com/apache/cloudstack/pull/11200#issuecomment-3127422030
Verified the fix with the below steps.
- Enabled local storage in the zone (restart cloudstack-management).
- Create a compute offering for local storage.
- Deploy an instance on the local storage (using the above offering).
- Restart the agent in KVM host, Stop and Start the instance deployed above.
Before FIX => Local pools removed after agent restart
