There are 66 instances in Openstack Havana. I think these instances are zombies instance. Dashboard displays Terminate Success info when I click Terminate Instance. But the instance still exists on dashboard and its status is Running. I have already kill all qemu-kvm program on server.
In Mysql, database nova remains a lot of data. I don't know where to start to delete these data. Could someone give me some advice ?? Thanks a lot.
I did this in the Icehouse release of OpenStack, maybe you can map this to the Havana release:
log into the database (you should see > mysql in your console)
select the nova database:
use nova;
mark the rows in table instances as deleted (that's a "soft-delete"):
update instances set deleted_at = updated_at, deleted = id, power_state = 0, vm_state = "deleted", terminated_at = updated_at, root_device_name = NULL, task_state = NULL where deleted = 0;
<-- That 'deletes' ALL your instances! Use show columns from instances; if you want to choose another column(s) for your where-clause.
update the cache in table instance_info_caches appropriately:
update instance_info_caches set deleted_at = updated_at, deleted = id where deleted = 0;
update the fixed_ips table:
update fixed_ips set instance_id = NULL, allocated = 0, virtual_interface_id = NULL where deleted = 0;
Note: If the column deleted contains a value not equal to zero, then this seems to be the way to say this row is supposed to be deleted. When I delete an instance via API, OpenStack seems to choose the id as value for deleted.
