--- other: - | The filter scheduler will now attempt to claim a number of resources in the placement API after determining a list of potential hosts. We attempt to claim these resources for each instance in the build request, and if a claim does not succeed, we try this claim against the next potential host the scheduler selected. This claim retry process can potentially attempt claims against a large number of hosts, and we do not limit the number of hosts to attempt claims against. Claims for resources may fail due to another scheduler process concurrently claiming resources against the same compute node. This concurrent resource claim is normal and the retry of a claim request should be unusual but harmless.
