Thx Konstantin for sharing, yes, I haven't tried to set the flavor root-disk-space to 0. I'm not sure what would happen, but it is probably worth trying. Is this because if you provision just an image, and the flavor say root_disk_space = 20G, then the image will have 20G ephemeral space in / on the compute node?
I will try the live-migration with -DiskFilter and see how that goes. thx! will On Mon, Aug 15, 2016 at 4:15 PM, <kostiantyn.volenbovs...@swisscom.com> wrote: > Hi, > > Just to add that this bug was recently brought up in openstack-dev [1] > > it sounds that you are waiting for fix via [2] or, probably more likely [3] > Disabling DiskFilter sounds like OK workaround in case your VMs are never > booted from image in your OpenStack Region(s). > But if I understand the fault - the migrate/resize/live > migrate/rebuild/evacuate will not work because > . assuming that on target Compute Host you don't have local disk - and your > flavor has more than 0 GB for root and/or ephemeral disk > -it would fail. > > So I would say that setting your root disk space to '0' in the flavor might > be a better workaround > > BR, > Konstantin > [1] http://lists.openstack.org/pipermail/openstack-dev/2016-August/101566.html > [2] https://review.openstack.org/#/c/200870/ > [3] https://review.openstack.org/#/c/355091/ > > >> -----Original Message----- >> From: William Josefsson [mailto:william.josef...@gmail.com] >> Sent: Sunday, August 14, 2016 5:47 PM >> To: openstack-operators@lists.openstack.org >> Subject: [Openstack-operators] DiskFilter Disabled - No valid host was found >> >> Hello, I got Error, no valid host was found while trying to provision and I >> could in >> nova-scheduler.log see that the DiskFilter failed to find a compute host.
