I tried to check the allocations on each compute node of a Ocata cloud, using the command: curl -s ${PLACEMENT_ENDPOINT}/resource_providers/${UUID}/allocations -H "x-auth-token: $TOKEN" | python -m json.tool I found that, on a few compute nodes, there are some instances for which there is not a corresponding allocation. On another Rocky cloud, we had the opposite problem: there were allocations also for some instances that didn't exist anymore. And this caused problems since we were not able to use all the resources of the relevant compute nodes: we had to manually remove the fwrong" allocations to fix the problem ... I wonder why/how this problem can happen ... And how can we fix the issue ? Should we manually add the missing allocations / manually remove the wrong ones ? Thanks, Massimo
