Comment 2 for bug 1829479

If the compute service is delete and never started up again then the fix for https://bugs.launchpad.net/nova/+bug/1724172 cannot clean up the allocation as that runs when the compute service comes up after the compute host is redeployed.

In this bug I see two possible cases:
a) if the compute-service is deleted and the compute host name has never been used again, then I don't see why it is a problem to keep some allocation in placement as we are only leaking allocation for something that will never be used again. Admin also can go and manually delete the allocation and the compute RP in placement after the compute service delete.

b) If the compute-service will be later re-created with the same host name then the bugfix in https://bugs.launchpad.net/nova/+bug/1724172 will clean up the allocation in placement at compute service restart

Dear reporter, which use case you are targeting with this bug report?

Cheers,
gibi
