Hi I'm trying to follow the idea to enable COW with cinder, but it seems like I'm missing something in a patching part (with this patch https://review.openstack.org/#/c/90644/1). Could someone please explain me how to apply the patch appropriately? And yeah, another question is whether I need it at all, cos it seems like the check should pass for the image with non-empty checksum and name. # rbd -p images ls 35c63591-9a41-462e-8944-9a98f0d6adc3 # glance image-list 35c63591-9a41-462e-8944-9a98f0d6adc3 # glance image-show 35c63591-9a41-462e-8944-9a98f0d6adc3 +------------------+--------------------------------------+ | Property | Value +------------------+--------------------------------------+ | checksum | cf2392db1f59d59ed69a8f8491b670e0 | container_format | bare | created_at | 2014-05-15T14:19:32 | deleted | False | disk_format | raw | id | 35c63591-9a41-462e-8944-9a98f0d6adc3 | is_public | True | min_disk | 0 | min_ram | 0 | name | CirrOS | owner | a5286f8e7e2440ab9e8fcc120d59b872 | protected | False | size | 41126400 | status | active | updated_at | 2014-05-15T14:19:35 +------------------+--------------------------------------+ # cinder create --image-id=35c63591-9a41-462e-8944-9a98f0d6adc3 5 ... # rbd -p volumes ls volume-e277ee70-6fd1-4cc0-8d1f-adbf8a387ec7 # rbd -p volumes info volume-e277ee70-6fd1-4cc0-8d1f-adbf8a387ec7 rbd image 'volume-e277ee70-6fd1-4cc0-8d1f-adbf8a387ec7': size 5120 MB in 1280 objects order 22 (4096 kB objects) block_name_prefix: rbd_data.639274b0dc51 format: 2 features: layering No COW... though image has checksum and name attributes set, and show_image_direct_url is set to True in glance-api.conf + all glance-* and cinder-* services were restarted. I'd really appreciate any help here. Thanks in advance! -------------- next part -------------- An HTML attachment was scrubbed...
