| chenying | yinwei_computer: Hi | 02:52 |
| yinwei_computer | as we used to meet an issue: resources being protected in plan get deleted anonymously, which will cause protection failure | 02:56 |
| yinwei_computer | I mentioned this issue in cinder replication bp review. One of cinder core suggests we propose another bp to discuss this issue and proposed changes. | 02:57 |
| openstackgerrit | chenying proposed openstack/smaug: Fix list protectable API error https://review.openstack.org/321329 | 02:58 |
| yinwei_computer | I will have wangliuan to propose a bp about open reference counting of cinder resources to other services. | 02:58 |
| yinwei_computer | just to let you know, since I have reported this issue as a bug. | 02:59 |
| *** zhurong has quit IRC | 02:59 | |
| yinwei_computer | what do you think? | 02:59 |
| yinwei_computer | chenying? | 02:59 |
| *** zhurong has joined #openstack-smaug | 03:00 | |
| chenying | That sounds good. open reference counting of cinder resources to other services? Can we add a check before calling "protect" rpc interface? | 03:04 |
| *** mingyu has joined #openstack-smaug | 03:05 | |
| *** pzchen has quit IRC | 03:06 | |
| yinwei_computer | the point is the resource being protected should not be deleted | 03:08 |
| yinwei_computer | it could be delete at any time point | 03:09 |
| yinwei_computer | during protection | 03:09 |
| yinwei_computer | passively checking won't work | 03:09 |
| openstackgerrit | smile-luobin proposed openstack/smaug: Add serialize and deserialize functions for resource_graph https://review.openstack.org/320804 | 03:09 |
| yinwei_computer | the reasonable procedure should be: first stop protection; then edit plan and remove the resource from the plan; and delete resource at last | 03:11 |
| yinwei_computer | same order as delete an in-use volume | 03:11 |
| *** mingyu has quit IRC | 03:14 | |
| *** pzchen has joined #openstack-smaug | 03:19 | |
| chenying | You think this procedure is done in smaug service internally. A user or tenant don't need know the protected resource witch have been deleted. Is that right? | 03:19 |
| yinwei_computer | Not sure if I got your point. | 03:21 |
| openstackgerrit | chenying proposed openstack/smaug: Fix create checkpoint API errors in protection service https://review.openstack.org/320754 | 03:21 |
| *** chenying_ has joined #openstack-smaug | 03:21 | |
| yinwei_computer | basically, I think resources in cinder may get referenced by other top layer services, like smaug, or nova | 03:22 |
| yinwei_computer | here comes the safe deletion issue: resource being referenced shouldn't be deleted directly by cinder | 03:22 |
| yinwei_computer | cinder should keep a reference counting | 03:22 |
| yinwei_computer | the problem is how to notify cinder that your volume is referenced by others. we need an API here. | 03:23 |
| yinwei_computer | Nova is a special case, which directly changes cinder volume status to in-use to solve this safe deletion issue. | 03:24 |
| yinwei_computer | but that's not a generic solution. | 03:24 |
| chenying_ | Can we push a bp to cinder to mark this volume being protected. cann't be delted. or must add force parameter and can be delted. | 03:24 |
| *** chenying has quit IRC | 03:24 | |
| yinwei_computer | it could be | 03:24 |
| yinwei_computer | either an additional status field or a reference counting, they are actually the same in functionality. | 03:25 |
| chenying_ | IMO, We can look other protject how to solve this problom. like freeze or dragon. | 03:26 |
| yinwei_computer | what do you mean by dragon? | 03:26 |
| yinwei_computer | flow dragon | 03:26 |
| yinwei_computer | yes, definitely | 03:26 |
| chenying_ | yes flow dragon | 03:26 |
| yinwei_computer | we could check existed ways and propose our bp | 03:26 |
| yinwei_computer | it could be a generic API: reference_resource/dereference_resource, or it could be a specific requirement: adding a field for smaug protection | 03:27 |
| yinwei_computer | not sure if they're the same case | 03:28 |

| chenying | https://review.openstack.org/320754 If this patch is merged, volume protect can work. volume protect full test will be submitted today or tomorrow. | 11:45 |
| yuval | chenying: that's it? :) | 11:46 |
| chenying | volume restore need a patch to fix bug. My environment block the verification. I think it will be submitted tomorrow. and with volume restore full test. | 11:48 |
| openstackgerrit | Yuval Brik proposed openstack/smaug: Implement the Resource Flow https://review.openstack.org/310386 | 11:50 |
