rosmaitaflwang: hello21:55
flwangrosmaita: hey, i just filed a bug, and i would like to get your comments21:56
flwangrosmaita: https://bugs.launchpad.net/glance/+bug/147382721:57
openstackLaunchpad bug 1473827 in Glance "Volume won't be deleted for image snapshoted from volume backed instance" [High,New] - Assigned to Fei Long Wang (flwang)21:57
flwangrosmaita: i would like to confirm if it's in glance scope, i think yes, but I want to get some ideas from you21:58
*** shakamunyi has joined #openstack-glance21:58
nikhil_kflwang: isn't that a bug for the glance_store?22:04
flwangnikhil_k: i'm not really sure, TBH :)22:05
flwangcoz i don't think it should be handled by each driver22:05
nikhil_kflwang: ah, where is the volume snapshot stored?22:05
flwangcinder22:05
nikhil_kflwang: yeah, then it seems like some bug in the cinder driver22:06
flwangnot really22:06
*** ayoung has quit IRC22:06
nikhil_kflwang: becasue as far as glance is concerned we delete the image and make a call to the driver.delete_data22:06
flwangbecause you will see the same issue with rbd driver :)22:06
nikhil_kI don't know about those two much, mind adding some logs/paste to the bug?22:07
rosmaitawhat exactly is the issue? is it that if you try to boot from the volume, it won't work because the image is gone?22:07
flwanghmm... but i haven't confirmed it on RBD driver yet22:07
flwangrosmaita: the problem is if we snapshot an instance  which is boot from volume22:07
flwangthen when user delete the image from glance22:07
flwangglance won't remove the volume from cinder22:08
*** edmondsw has quit IRC22:08
rosmaitaok, but why do we want the volume removed from cinder?22:08
flwangthat's the point22:08
flwangshould we(glance) take care the image data?22:08
rosmaitanot once it's been copied onto a volume, i don't think22:09
flwangi run into this issue because i'm working on a nava backup feature22:09
flwangfor nova backup, it will rotate the image creation.22:10
flwangif the instance is image based, then everything is ok, nova just needs to delete the image, because the image data will be deleted by glance22:10
*** kebray has joined #openstack-glance22:11
flwangbut if the instance is volume backed, then during the rotation, i'm not really sure if nova or glance should take care the snapshot volume deletion22:11
rosmaitasounds like either nova or some 3rd service22:12
rosmaitaglance really doesn't keep track of what you do with its images22:12
rosmaitasounds like nova or the service would be the one who knew what was going on22:12
flwangok, let's make the question be simple22:12
rosmaitayeah, i may be misunderstanding22:13
flwangif user create an image by nova snapshot, and the instance was boot from volume22:13
flwangthen when the image is delete, should the volume be removed as well?22:13
flwangabove is a more simpler user scenario22:14
rosmaitawhen you say "nova snapshot" , you mean POST v2/tenantid/servers/serverid/action22:14
*** cdelatte has joined #openstack-glance22:14
flwangnova image-create22:14
rosmaitaok22:14
*** delattec has joined #openstack-glance22:14
nikhil_kit sounds like the sys disk would be stored in glance backed store and the attached volume would be handled by cinder22:16
rosmaitaflwang: is the scenario that i have an instance that's boot from volume, i do image-create Monday, Tuesday, Wed, and then want to delete Mon and Wed22:16
rosmaitaseems like you don't necessarily want to touch the volume in that case22:16
nikhil_ksys disk should be deleted and the volume stored in cinder is cinder's responsiblity22:16
flwangrosmaita: nova backup support the function you mentioned above, but even for nova snapshot, it has the similar 'issue'22:17
flwangnikhil_k: there is no sys disk22:17
rosmaitai agree with nikhil_k that it's cinder's responsibility to delete volumes, and not glance's responsibility to tell cinder to delete22:17
rosmaitahmmm22:17
rosmaitai am probably still misunderstanding22:18
rosmaitahow about this ... what's the coupling between the image and the volume?22:18
flwangif you have a devestack, or you can access rackspace cloud, you can do a test :)22:18
rosmaitaif you delete one of them, does the other become useless?22:18
flwangrosmaita: i think so22:18
*** annegentle has quit IRC22:18
flwangbecause it's an 'image', though it's store in cinder as a volume22:19
nikhil_kflwang: cinder's volumes are stored as images in glance22:20
flwangthe steps are: 1. boot an instance based on volume 2. nova image-create   3. delete the image from glance 4. you will still see it from cinder's snapshot list22:20
nikhil_kseems like it's record is being kept in two places ??22:21
rosmaitawhy is cinder keeping track of glance images?22:21
rosmaitai thought cinder has its own snapshot mechanism for volumes?22:21
flwangrosmaita: so do you think the scenario i described above is a normal case?22:22
rosmaitayou mean the steps you numbered above?22:23
rosmaita(sorry to be so dense today)22:23
flwangrosmaita: yes22:23
rosmaitawell, on that scenario ...22:23
rosmaitai'm wondering why the image shows up in cinder's list at all22:23
flwangbecause from the end user perspective, they maybe confused because glance is acting different when delete an image22:24
flwangsometimes it will delete the image 'data', but sometimes glance won't22:24
flwangi'm trying to make it clear for the 'won't delete' case :)22:24
*** vijendar has quit IRC22:25
flwangrosmaita: because nova just create a cinder snapshot for the instance's volume22:25
rosmaitai guess i'll have to think about it some more22:28
flwangok, no worries22:28
rosmaitamy gut feeling is that if you put your 'data' in two places, (1) an image in glance, and (2) a volume in cinder,  you might want to keep one of them and delete the other22:29
flwangrosmaita: you can find some discussion at here https://review.openstack.org/#/c/164494/23/nova/compute/manager.py22:29
rosmaitaok, thanks22:29
