Hi everyone,
I'm using OpenStack Mitaka version (deployed from Fuel 9.2)
In present, I installed two different model of GPU card.
And wrote these information into pci_alias and pci_passthrough_whitelist
in nova.conf on Controller and Compute (the node which installed GPU).
Then restart nova-api, nova-scheduler,and nova-compute.
When I check database, both of GPU info registered in pci_devices table.
Now I removed one of the GPU from compute node, and remove the
information from nova.conf, then restart services.
But I check database again, the information of the removed card still
exist in pci_devices table.
How can I do to fix this problem?
So, when you removed the GPU from the compute node and restarted the
nova-compute service, it *should* have noticed you had removed the GPU
and marked that PCI device as deleted. At least, according to this code
in the PCI manager:
https://github.com/openstack/nova/blob/master/nova/pci/manager.py#L168-L183
Question for you: what is the value of the status field in the
pci_devices table for the GPU that you removed?
Best,
-jay
p.s. If you really want to get rid of that device, simply remove that
record from the pci_devices table. But, again, it *should* be removed
automatically...
