commit 6b0ab40e4233a480c9bdcca657f594d7e90fadc8 Author: Balazs Gibizer <[email protected]> Date: Mon Aug 7 15:12:25 2017 +0200 Raise NoValidHost if no allocation candidates Placement took over the role of the CoreFilter, RamFilter and DiskFilter from the FilterScheduler. Therefore if placement returns no allocation candidates for a request then scheduling should be stopped as this means there is not enough VCPU, MEMORY_MB, or DISK_GB available in any compute node for the request.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1708637 Title: nova does not properly claim resources when server resized to a too big flavor Status in OpenStack Compute (nova): Fix Released Bug description: Problematic scenario: Boot a server then try to resize it to a flavor which requests more vcpu than what available in any compute hosts. If the CoreFilter is enabled then the resize fails with NoValidHost and the resource allocation is OK. However if the CoreFilter is not enabled in the FilterScheduler then the resize is accepted but the placement API is not updated with the actual resource (over) allocation. In this case I don't know which would be the expected behavior: Option A: No valid host shall be raised Option B: Resize is accepted and the resources state are updated properly There is a patch proposed with functional tests that reproduces the problem https://review.openstack.org/#/c/490814 To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1708637/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
