Ubuntu Focal Ussuri can't create a snapshot from running instance
by Cristina Mayo Sarmiento 20 Oct '20

20 Oct '20

Hi all, I don't have a lot experience with Openstack. I've installed Ussuri on my cloud. I have 1 controller node and 2 compute nodes. I'm not able to create a snapshot from a running instance, but it works perfectly if the instance is turned off. I checked the logs on controller node about glance-api and POST method executes fine, but suddenly appears a DELETE that seems remove the image: "POST /v2/images HTTP/1.1" 201 1254 0.045379 "GET /v2/images/c647160b-416d-4c98-bbe2-6302a509f 941 HTTP/1.1" 200 1097 0.014154 WARNING glance.api.v2.images [req-e29704f9-e147-42df-914c-6217c60ada30 c63d05ad0e9d43ebb0fd31f442156a2a c2 b7d6242f3140f09d283e8fbb88732a - default default] After upload to backend, deletion of staged image data has failed because it cannot be found at /tmp/staging//c647160b-416d-4c98-bbe2-6302a509f941 "DELETE /v2/images/c647160b-416d-4c98-bbe2-6302a5 09f941 HTTP/1.1" 204 213 0.140731 I have these versions installed: - python3-glance-store/focal,now 2.0.0-0ubuntu1 all [instalado, automático] - python3-glance/focal-updates,now 2:20.0.1-0ubuntu1 all [instalado, automático] Could anyone help me?

[largescale-sig] "Share your OpenStack scaling story" forum session
by Thierry Carrez 20 Oct '20

20 Oct '20

Hi everyone, In a few hours at 14:30UTC we'll have a Forum session where everyone is invited to share their scaling story. As you add nodes to an OpenStack cluster, at one point you hit scaling limitations that force you to scale out to multiple clusters, cells or zones. What breaks first? At which scale? The Large Scale SIG is working on pushing back the scaling limits within a single cluster. To that effect, it is collecting scaling stories from OpenStack deployers. This should lead to identifying common cases, usual suspects that the SIG can focus on, in order to raise scaling limitations within one cluster and reduce the need to scale out to multiple clusters too early. Join fellow OpenStack operators and share your experience and horror stories, adding nodes to OpenStack clusters! In case the event platform plays games again, you can access the session directly at: https://zoom.us/j/94011749848?pwd=Qmo5c1ZMK3RJWnVRSjZzZWFkTng3QT09 And the etherpad is at: https://etherpad.opendev.org/p/vSummit2020_OpenStackScalingStory See you all there! -- Thierry Carrez (ttx)

[nova] NUMA scheduling
by Eric K. Miller 19 Oct '20

19 Oct '20

Hi, I'm at a loss for finding good information about how a VM's vCPUs and Memory are assigned to NUMA nodes within a scheduled physical host. I think Libvirt does this, and the Nova Scheduler simply finds the right physical host to run the VM, and thus Nova has no input on which NUMA node to choose. So this might be a Libvirt question. We are running Stein and have the issue where VMs launch on NUMA Node 0, and not on NUMA Node 1, in physical hosts with two processors, and are simply looking for a way to tell Libvirt to consider NUMA Node 1 when scheduling a VM, since there is nearly all of the memory available on NUMA Node 1. Our flavors are defined with hw:numa_nodes='1' since we want all vCPUs+Memory to land on a single NUMA Node, and so the guest OS has visibility that a single NUMA Node is being used. We are "not" looking for a way to pin a VM to a specific NUMA node (such as for SR-IOV purposes). Any suggestions where to look for the solution? Thanks! Eric
