Hmm, very odd indeed. Any way you can save the nova-compute logs from
when you removed the GPU and restarted the nova-compute service and
paste those logs to paste.openstack.org? Would be useful in tracking
down this buggy behaviour...

Hi Jay,
The status of the "removed" GPU still shows as "Available" in
pci_devices table.

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
<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,

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...
