OK so nova and cinder are both at the queens release, which means when you attach the volume to the server, the compute API should create a volume attachment record on the given volume. If the volume is in 'error' status I'd expect that to fail like how the old volume reserve action would fail for a volume in error status.
Looking at the cinder volume attachment create code, it should fail if the volume isn't in 'available' or 'downloading' status: https://github.com/openstack/cinder/blob/9bc9a528ef46522fd727a2a047da435c658a15c5/cinder/volume/api.py#L2084 It seems that this is the problem - because there is an instance_uuid, override=True: https://github.com/openstack/cinder/blob/9bc9a528ef46522fd727a2a047da435c658a15c5/cinder/volume/api.py#L2093 And then the volume statis us changed to reserved: https://github.com/openstack/cinder/blob/9bc9a528ef46522fd727a2a047da435c658a15c5/cinder/volume/api.py#L2111 Then once the attach on the compute actually fails, we'd delete the attachment from the nova side and the volume will be back in 'available' status because it no longer has any attachments: https://github.com/openstack/cinder/blob/9bc9a528ef46522fd727a2a047da435c658a15c5/cinder/volume/api.py#L2193 Compare that to how the volume "reserve" action works: https://github.com/openstack/cinder/blob/9bc9a528ef46522fd727a2a047da435c658a15c5/cinder/volume/api.py#L690 If the volume isn't 'available' it will fail. ** Also affects: cinder Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1785050 Title: Volume status changed from error to available Status in Cinder: Triaged Status in OpenStack Compute (nova): Invalid Bug description: Description =========== After creating a volume which resulted with status = "error", an attempt to attach the volume to VM will fail and will change the volume status to - "available". Steps to reproduce ================== 1. Create volume with status = "error". 2. Try to attach the volume to the VM. 3. Check the volume status. Expected result =============== 1. Volume will be created with status = "error". 2. Attachment to VM will failed. 3. Volume status will be - "error" Actual result ============= 1. Volume created in status = "error". 2. Attachment attempt to VM will fail. 3. Volume status changed from "error" to "available".
