| Yanyanhu | hi, elynn, around? | 08:32 |
| elynn | Hi | 08:32 |
| Yanyanhu | I found the attribute schema has not been added yet? | 08:34 |
| Yanyanhu | https://github.com/lynic/templates/blob/master/senlin/heat_resource/resources/senlin/cluster.py | 08:34 |
| Yanyanhu | in this test code | 08:34 |
| elynn | yes, attribute for cluster haven't been added yet. | 08:34 |
| Yanyanhu | only find the schema definition of properties | 08:34 |
| Yanyanhu | ok, got it | 08:34 |
| elynn | Do you think what kind of attributes need to add? | 08:35 |
| Yanyanhu | hmm, still need to think about it | 08:35 |
| Yanyanhu | oh, what you mean by the 'spec' attribute of cluster? | 08:36 |
| Yanyanhu | the spec of profile used to create cluster? | 08:36 |
| elynn | only profile has 'spec' attribute | 08:38 |
| elynn | Oh... you mean https://github.com/lynic/templates/blob/master/senlin/heat_resource/resources/senlin/cluster.py#L47-L51 | 08:38 |
| Yanyanhu | yes :) | 08:38 |
| elynn | I haven't update it yet... Just copy/paste from profile.py | 08:39 |
| Yanyanhu | ok, I see | 08:39 |
| elynn | Will update it ASAP | 08:39 |
| Yanyanhu | thanks, I guess we need to consider some typical autoscaling scenarios when trying to decide what attrs we want to support in cluster resource | 08:40 |
| elynn | A question about senlin, can a cluster be locked by multi action? | 08:42 |
| elynn | yes, do you think the attributes from cluster-show is enough? | 08:42 |
| Yanyanhu | I'm not sure whether we should add min_size, max_size and desired_capacity into attrs list | 08:43 |
| Yanyanhu | since they are usually defined by user | 08:43 |
| Yanyanhu | so it looks like we don't need expose them as attribute | 08:43 |
| Yanyanhu | what is the common pratice in heat for this kind of attrs? | 08:44 |
| elynn | https://github.com/openstack/heat/blob/master/heat/engine/resources/openstack/heat/autoscaling_group.py#L42-L46 | 08:45 |
| elynn | ASG will expose the output value. | 08:46 |
| Yanyanhu | yes, I think current_size is needed | 08:46 |
| Yanyanhu | hmm, but for senlin, we don't have output I think | 08:46 |
| elynn | yes, maybe just current size for now? | 08:47 |
| Yanyanhu | guess so, besides name, id | 08:47 |
| elynn | and a list of node id? | 08:47 |
| elynn | https://github.com/openstack/heat/blob/master/heat/engine/resources/openstack/heat/resource_group.py#L196-L208 | 08:47 |
| Yanyanhu | yes, agree | 08:48 |
| Yanyanhu | hi, elynn, I guess maybe also each node's detail | 08:56 |
| Yanyanhu | like the ip addresses of a nova server | 08:57 |
| elynn | I don't think a node is just a server, since it could be a heat stack... | 08:58 |
| Yanyanhu | maybe just name it as 'node_details'. It can be a list which has the following format ['ID_NODE1': {detail_node_1}, 'ID_NODE2': {detail_node_2}] | 08:58 |
| Yanyanhu | yes, for node which is a heat stack, its detail information will be different | 08:59 |
| Yanyanhu | what detail information you can get depends on the 'get_details' method defined in profile | 08:59 |
| elynn | ok, no problem | 08:59 |
| Yanyanhu | need more discussion about this issue I think :) | 09:00 |
| elynn | Senlin hase 'get_details' in profile? | 09:00 |
| Yanyanhu | yes | 09:01 |
| Yanyanhu | http://git.openstack.org/cgit/openstack/senlin/tree/senlin/profiles/os/nova/server.py#n336 | 09:02 |
| Yanyanhu | like this | 09:02 |
| elynn | Is there any client method to get it? | 09:03 |
| Yanyanhu | yes, I think there is client interface for it | 09:03 |
| Yanyanhu | let me check the code | 09:03 |
| Yanyanhu | add -D or --details option when performing node-show operation | 09:04 |
| Yanyanhu | will give you the detail information of a node | 09:04 |
| elynn | ok. I see it. | 09:05 |
| Yanyanhu | http://git.openstack.org/cgit/openstack/python-senlinclient/tree/senlinclient/v1/client.py#n227 | 09:06 |
| elynn | So for now we can add two attrs for cluster, node_list and current_size | 09:07 |
| elynn | or node_details is better? | 09:08 |
| Yanyanhu | yes, I also prefer node_details | 09:08 |
| xuhaiwei | just a question, we will add two new attrs for cluster?? | 09:09 |
| xuhaiwei | or that is related to heat resource? | 09:09 |
| Yanyanhu | just related to heat resource | 09:09 |
| xuhaiwei | got it | 09:10 |
| Yanyanhu | since senlin cluster implementation has supported them and we believe they will be useful for user :) | 09:10 |
| elynn | Will work on it. | 09:14 |
| Yanyanhu | thanks. maybe you can also give a quick update about this work in tonight's irc meeting? | 09:14 |
| elynn | ok | 09:16 |
| xuhaiwei | elynn, will you share us the heat resource work in tonight's meeting? | 09:19 |
| elynn | yes, I will | 09:19 |
| xuhaiwei | just didn't see yanyan's message | 09:19 |
| xuhaiwei | :( | 09:19 |
| elynn | Do we bump the client version yet? | 09:20 |
| elynn | After Qiming's revise patch merged. | 09:20 |
| xuhaiwei | not sure about that | 09:21 |
| Yanyanhu | hi, elynn, I guess so | 09:22 |
| Yanyanhu | I think qiming will handle this. It is important for your work in heat side :) | 09:22 |
| elynn | yes, waiting for global-requirement to bump version too... | 09:23 |
| Yanyanhu | yea | 09:24 |
| openstackgerrit | Ethan Lynn proposed openstack/senlin: [WIP]Steal lock when engine is dead https://review.openstack.org/243483 | 09:29 |
| elynn | Feel free to comment on ^^ | 09:31 |
| Yanyanhu | sure | 09:34 |
| xuhaiwei | elynn, should we do this after multi-engine is supported? | 09:37 |
| elynn | We don't support multi-engine yet? | 09:38 |
| xuhaiwei | not yet | 09:38 |
| elynn | sigh... | 09:38 |
| Yanyanhu | xuhaiwei, elynn, we have | 09:39 |
| Yanyanhu | and I have made some simple tests about it | 09:40 |
| Yanyanhu | I think it works in normal cases | 09:40 |
| xuhaiwei | the match is merged? | 09:40 |
| Yanyanhu | xuhaiwei, yes, you can set the engine worker number in the senlin.conf | 09:40 |
| Yanyanhu | but we still need to do more test about it and fix any possible issues | 09:41 |
| elynn | Do we have any command line to list engines? | 09:42 |
| Yanyanhu | especially about the issues that happen during concurrent DB access | 09:42 |
| Yanyanhu | elynn, not yet | 09:42 |
| Yanyanhu | I know heat has related support :) | 09:42 |
| elynn | yes, through 'heat-manage serviece list' | 09:42 |
| Yanyanhu | So I think the multi-engine support in senlin is still in working progress. Maybe we can expose related interfaces user after we ensure it is stable. | 09:44 |
| Yanyanhu | to user | 09:44 |
| Yanyanhu | hi, xuhaiwei, you can change this option to test multi-engine http://git.openstack.org/cgit/openstack/senlin/tree/etc/senlin/senlin.conf.sample#n227 | 09:45 |
| xuhaiwei | thanks | 09:46 |
| Yanyanhu | maybe I should also enable multi-engine environment when doing functional test | 09:46 |
| Yanyanhu | np | 09:46 |
| xuhaiwei | I just changed it to 2 | 09:46 |
| Yanyanhu | it should work I think :) | 09:46 |
| xuhaiwei | and restarted senlin-engine service | 09:46 |
| xuhaiwei | it seems still only one engine is working | 09:47 |
| Yanyanhu | oh, really, let me check it. I tested with 4 engine workers about a month ago. | 09:48 |
| Yanyanhu | it works well in my env | 09:48 |
| xuhaiwei | I just checked the running process, only one engine is running | 09:48 |
| Yanyanhu | hmm, weird, I can see three engine processes if I set num to 3 | 09:49 |
| xuhaiwei | now it's rnning | 09:49 |
| xuhaiwei | running | 09:49 |
| xuhaiwei | but with 3 engine running | 09:50 |
| Yanyanhu | ok | 09:50 |
| xuhaiwei | I guess the former one is not killed | 09:50 |
| Yanyanhu | the first one is the initial one I think | 09:50 |
| Yanyanhu | no, it was | 09:50 |
| xuhaiwei | so when we set it to 2, it should have 3 running? | 09:51 |
| Yanyanhu | I think the first one is the parent process of other ones | 09:52 |
| Yanyanhu | so you can see it in ps result | 09:53 |
| Yanyanhu | the basic support is provided by oslo_service | 09:53 |
| Yanyanhu | let me find the code | 09:53 |
| xuhaiwei | I think you are right, when I kill the first one, all are killed | 09:54 |
| Yanyanhu | http://git.openstack.org/cgit/openstack/senlin/tree/bin/senlin-engine#n55 | 09:54 |
| Yanyanhu | yep | 09:54 |
| Yanyanhu | you can use multi-engine environment for your daily work. That will be very helpful for finding bug :) | 09:55 |
| xuhaiwei | but the Child can not be killed, when I try to kill it, it is recreated | 09:56 |
| xuhaiwei | is there any configuration for it? | 09:56 |
| Yanyanhu | yes, that's intended :) | 09:56 |
| Yanyanhu | no sure... I saw related code about auto recreating before | 09:57 |
| Yanyanhu | you're supposed to use service start/stop to control the lifecycle of all engine threads | 09:58 |
| Yanyanhu | will go back home. Talk to you guys later | 09:59 |
| xuhaiwei | ok | 09:59 |
| xuhaiwei | I forced to kill a heat-engine | 10:00 |
| xuhaiwei | succeeded | 10:00 |
| Yanyanhu | :) | 10:00 |
| xuhaiwei | see you later, I will go home too | 10:00 |
| Yanyanhu | you can kill any process in user mode if you have root privilege in Linux :) | 10:00 |
