Re: [Openstack] Migrating cinder volumes to a new cluster

Hi Jim! I think that the plan is good. I think Cinder should not delete anything unless told to do so. You have to create the CPG space manually before Cinder can start using it, so it does no initialization. Do you have opportunity to test it, on some other CPG perhaps? We have the same setup

Re: [Openstack] VMs lost IP after running for few days on OpenStack Liberty.

Hi Dan, that normally should not happen. Presuming you are running Neutron, it may be two things – either your DHCP agent died and the instances could not renew their IPs, or the DHCP client inside them died, or as third variant, your RabbitMQ bus is broken and the DHCP agents don’t have actual

Re: [Openstack] poor bandwidth across instances running on same host

Sorry to shatter you expectations, but those numbers are perfectly OK. I was testing on HPE DL380 gen9 with Intel Xeon E5-2630v3 and I got these speeds between two KVM VMs on the same host using netp

Re: [Openstack] dhcp namespace and vert pairs?

Hi! I think that the DHCP server does not work for the laptop because it only server MAC:IP pairs configured by Neutron. You can confirm by stealing a MAC address configured to an instance. Stop it and try dhclient ;-). However, I'm not enough of a Neutron guru to guarantee you that you will be

Re: [Openstack] Compute Node shutdown how to prevent instance suspend

Hi! When I need to reboot a compute node (because of some driver lock-up or such problems), I first stop nova-compute so that it does not report the shutoff state of VMs to the database and resume_guests_state_on_host_boot=true does actually start them. Then I press the power switch on the VMs

Re: [Openstack] Computer Science Master's Thesis Topics?

Hi Felix! I'm a PhD student at CTU FEE. My own topic was simulation of automatic scaling using both the event-driven approach and queue network modelling. The second part of the thesis was on the prediction of web server workload in time. If you wanted, you could continue and simulate some predi

Re: [Openstack] volume state (in-use/available) vs real work

Hi! whether this works or not depends on the backend. For example, on Fibre Channel, the VM would still see the same size, because it is still presented from the storage to the hypervisor with the same size. Changing it on the fly requires you to dig deep in Linux SCSI rescans and device mapper
