Instance Unexpectedly Not Found
Problem
- Instance operations (start, stop, reboot, resize, etc.) are failing for an instance and it is in 'ERROR' state.
- Instance 'fault' field is populated with an error similar to the following.
- The hypervisor log shows that the instance is "unexpectedly not found".
-- /var/log/pf9/ostackhost.log --
- The ephemeral disk file and XML metadata still exist on the instance storage path.
Environment
- Platform9 Managed OpenStack - All Versions
- Nova
Cause
The instance failed to boot previously.
Resolution
- Perform a hard-reboot of the instance to attempt to re-define the instance via Nova (CLI only).
- If a hard-reboot doesn't work to address the issue, re-define the instance manually on the hypervisor using the 'virsh' utility.
