Hi Volker, Sounds like your flavor’s storage extra spec doesn’t match the storage configuration for the computes. ‘local_image’ is the default value for a flavor. You can specify the extra spec from the CLI by setting the following parameter for a flavor: aggregate_instance_extra_specs:storage=storage_type where storage_type is one of the following: * local_lvm - Specifies hosts with LVM-backed local storage for use by the VM. * local_image - Specifies hosts with image-backed local storage for use by the VM. * remote - Specifies hosts with Ceph-backed remote storage for use by the VM. For example: Looks like you need to set: nova flavor-key flavor_name set aggregate_instance_extra_specs:storage=remote Regards, Bob From: "von Hoesslin, Volker" <Volker.Hoesslin@swsn.de> Date: Monday, November 12, 2018 at 10:56 AM To: "'starlingx-discuss@lists.starlingx.io'" <starlingx-discuss@lists.starlingx.io> Subject: [Starlingx-discuss] set([remote]) do not match local_image hmmmm, this doesn't stop :( now I can set up the complete stack in one go. but as soon as I try to set up a VM (cirrOS 0.4.0 as RAW or QCOW2) I get the following error: compute-0: (AggregateInstanceExtraSpecsFilter) extra_specs 'set([u'remote'])' do not match 'local_image', compute-1: (AggregateInstanceExtraSpecsFilter) extra_specs 'set([u'remote'])' do not match 'local_image'. as usual i followed the original instructions from the doku: https://docs.starlingx.io/installation_guide/dedicated_storage.html#dedicate... what am I doing wrong?
