No I have not, I guess there is nothing else to do than just give it a go :) Thanks for the pointer From: Marcin Iwinski Date: Friday 23 September 2016 at 11:39 To: David Orn Johannsson, "openstack-operators at lists.openstack.org<mailto:openstack-operators at lists.openstack.org>" Subject: Re: [Openstack-operators] Evacuate host with host ephemeral storage On 23 Sep 2016 at 13:25:39, Davíð Örn Jóhannsson (davidoj at siminn.is<mailto:davidoj at siminn.is>) wrote: OpenStack Liberty Ubuntu 14.04 I know that using block storage like Cinder you can evacuate instances from hosts, but in my case we are not yet using Cinder or other block storage solutions, we rely on local ephemeral storage, configured on using LVM Nova.conf [libvirt] images_volume_group=vg_ephemeral images_type=lvm Is it possible to evacuate (migrate) ephemeral instances from compute hosts and if so does any one have any experience with that? Hi Davíð Have you actually tried the regular "nova migrate UUID" option? It does copy the entire disk to a different compute - but i'm not sure if it's working with LVM. I've also used [1] ("nova live-migrate --block-migrate UUID") in the past - but unfortunately this also wasn't LVM backed ephemeral storage.
