Hello Mattm
Yes I mean sometimes I have same host/node names with different uuid in
compute_nodes table in nova database
I must delete nodes with uuid those not match with nova-hypervisor list
command.
At this time I have the following:
MariaDB [nova]> select hypervisor_hostname,uuid,deleted from compute_nodes;
+---------------------+--------------------------------------+---------+
| hypervisor_hostname | uuid | deleted |
+---------------------+--------------------------------------+---------+
| tst2-kvm02 | 802b21c2-11fb-4426-86b9-bf25c8a5ae1d | 0 |
| tst2-kvm01 | ce27803b-06cd-44a7-b927-1fa42c813b0f | 0 |
+---------------------+--------------------------------------+---------+
2 rows in set (0,00 sec)
But sometimes old uuid are inserted in the table .
I deleted again them.
I restarted kvm nodes and now the table is ok.
I also restarded each controller and the tables is ok.
I do not know because 3 days ago I had same compute nodes names with
different uuids.
Thanks and Regards
Ignazio
OK I guess if it happens again, please get the
host/hypervisor_hostname/uuid/deleted values from the compute_nodes
table before you cleanup any entries.
Also, when you're deleting the resources from the DB, are you doing it
in the DB directly or via the DELETE /os-services/{service_id} API?
Because the latter cleans up other related resources to the nova-compute
service (the services table record, the compute_nodes table record, the
related resource_providers table record in placement, and the
host_mappings table record in the nova API DB). The resource
provider/host mappings cleanup when deleting a compute service is a more
recent bug fix though which depending on your release you might not have:
