| m3m0 | Hello everyone, sorry for the delay | 15:12 |
| m3m0 | all: notes available in https://etherpad.openstack.org/p/freezer_meetings | 15:12 |
| m3m0 | let's do a quick round on the project | 15:13 |
| m3m0 | fabriziov you are first | 15:13 |
| fabriziov | ok | 15:14 |
| fabriziov | I'm working on the lvm options | 15:14 |
| fabriziov | small change to make the agent more "smart" in identifying the mount point and the directory to "cd" into | 15:15 |
| fabriziov | that would result also in less options required from the user in case of lvm snapshots | 15:16 |
| fabriziov | so better usability | 15:16 |
| fabriziov | also | 15:16 |
| fabriziov | should be ready by tomorrow at last | 15:16 |
| *** dschroeder has joined #openstack-freezer | 15:17 | |
| m3m0 | the lvm change, is a bug? or just an enhancement? | 15:18 |
| fabriziov | kind of a bug actually. | 15:18 |
| fabriziov | if the mount point of the directory to backup is not / | 15:19 |
| m3m0 | do we have a bug assigned to this in launchpad? | 15:19 |
| fabriziov | the path-to-backup option will not contain the whole path | 15:19 |
| fabriziov | hmmm dont think so | 15:19 |
| fabriziov | I will create a bug in launchpad | 15:20 |
| m3m0 | thanks :) | 15:21 |
| m3m0 | do you have anything more to add? | 15:21 |
| fabriziov | there is a blueprint to improve usability which seems relative to this issue | 15:22 |
| fabriziov | https://blueprints.launchpad.net/freezer/+spec/improve-freezer-usability | 15:22 |
| fabriziov | Saad just told me he was working on this. I'll check with him | 15:22 |
| fabriziov | We | 15:23 |
| fabriziov | We'll make sure this will solve the problem | 15:23 |
| m3m0 | but if we are planning to send that patch as a bug fix, we should document the bug separately | 15:23 |
| fabriziov | yes. I think filing the bug makes sense anyway | 15:23 |
| fabriziov | Besides that I'm still reading about the openstack and gozer ci toolchain for integration tests | 15:25 |
| m3m0 | do you need any help with that? | 15:25 |
| fabriziov | well, I can definitely use some help with that. | 15:28 |
| m3m0 | we should prioritize the current tasks | 15:29 |
| fabriziov | if anyone has relevant docs or links or some spare mental resources :) | 15:29 |
| fabriziov | yep. atm I want to close the lvm stuff. | 15:30 |
| fabriziov | Since Saad has already taken a look into it, it should be fairly quick to fix it | 15:30 |
| fabriziov | there's also a minor issue about the frequency of keystone requests made from the keystonemiddleware | 15:32 |
| fabriziov | on behalf of the freezer-api | 15:33 |
| m3m0 | what's the situation there? | 15:33 |
| fabriziov | maybe just enabling some caching solves | 15:34 |
| m3m0 | do we have timeouts? | 15:35 |
| fabriziov | from what I've got, it seems that the keystonemiddleware queries keystone too often to validate the user credentials. | 15:35 |
| m3m0 | or tokens not valid? | 15:35 |
| fabriziov | it's not a timeout problem, I think it's just that keystone receives many requests and this might be a concern | 15:36 |
| m3m0 | we should look in the docs if we can query once per token "life" | 15:36 |
| fabriziov | in other words, the keystonemiddleware is not a "good citizen" and might stress the keystone server too much :) | 15:37 |
| fabriziov | my idea is go for memcached and check the token timeout parameters | 15:38 |
| m3m0 | is that something that we want to do for HLM? | 15:39 |
| szaher | I think the cache will solve the problem | 15:40 |
| szaher | token is valid for 24 hours only | 15:40 |
| fabriziov | HLM, yes | 15:40 |
| szaher | http://docs.openstack.org/developer/keystone/configuration.html | 15:40 |
| szaher | here you will find enabling cache will solve the problem | 15:41 |
| m3m0 | we can use this | 15:41 |
| m3m0 | #token_cache_time=300 | 15:41 |
| m3m0 | http://docs.openstack.org/developer/keystonemiddleware/middlewarearchitecture.html | 15:41 |
| fabriziov | yes memo, that's precisely the documentation I was looking into. | 15:41 |
| m3m0 | perfecto :) | 15:41 |
| fabriziov | Saad, the problem seems to be that the keystonemiddleware queries keystone when it does not need to. | 15:42 |
| fabriziov | not a keystone problem, but rather a keystonemiddleware one | 15:43 |
| szaher | Okay | 15:43 |
| fabriziov | the fact that there are more than one apis behind a HAProxy reduces the gain of using the cache, but not so much I think | 15:45 |
| m3m0 | do you have anything more to add fabriziov? | 15:49 |
| fabriziov | no. thanks memo | 15:51 |
| m3m0 | thanks :) | 15:51 |
| m3m0 | reldan, you're next | 15:51 |
| reldan | Thank you, m3m0! | 15:51 |
| reldan | My code with first iteration of parallel backup is in master! And it works. So my next step is changing our config file | 15:52 |
| m3m0 | congratulations :) | 15:52 |
| reldan | It should accept OS credentials as well as multiple storages | 15:52 |
| reldan | Thank you! | 15:53 |
| reldan | Today I did a small fix to my ssh storage - I have added SSH_PORT | 15:53 |
| reldan | So I’m going to work on config files for storages. I would like to ask Fabrizio Vanni to help me | 15:54 |
| reldan | It’s all from my side | 15:54 |
| m3m0 | you should have a small meeting to discuss this offline then :) | 15:54 |
| m3m0 | thanks a lot | 15:54 |
| m3m0 | szaher, you're next | 15:54 |
| szaher | Thank you, m3m0 | 15:54 |
| szaher | I was working on throttling bandwidth bug, because it's not working for https | 15:55 |
| szaher | I used a 3rd party app called trickle to limit bandwidth on linux and will search for something suitable for windows | 15:56 |
| szaher | the code for limiting bandwidth on linux is in master now | 15:56 |
| m3m0 | perfect, those are great news | 15:56 |
| m3m0 | thanks a lot | 15:56 |
| szaher | also I've been working on another task | 15:56 |
| szaher | https://blueprints.launchpad.net/freezer/+spec/improve-freezer-usability | 15:56 |
| m3m0 | are you planning on working on usability next ? | 15:56 |
| szaher | this blueprint I created to improve freezer usability | 15:56 |
| m3m0 | perfect | 15:56 |
| m3m0 | are we planning to move to cliff? | 15:57 |
| szaher | container, there is a default value for container | 15:57 |
| m3m0 | https://github.com/openstack/cliff | 15:57 |
| m3m0 | for the arguments? | 15:57 |
| szaher | Okay, this is another issue | 15:57 |
| szaher | we need to be aligned with openstack standards | 15:58 |
| szaher | but for the time being we need to fix some usability issues to make user life easier | 15:58 |
| szaher | * lvm_dirmount | 15:58 |
| szaher | * container | 15:58 |
| szaher | * path_to_backup with lvm snapshots | 15:58 |
| szaher | We need to provide default value for those 3 parameters | 15:58 |
| szaher | the first two are done now, I'm working on the third one and once I finish I'll commit | 15:59 |
| m3m0 | why container? | 15:59 |
| szaher | we can plan for using cliff to rearrange our arguments | 15:59 |
| szaher | container it's already in, If the user didn't provide a container name freezer will use freezer_backups | 15:59 |
| m3m0 | and for local and ssh? | 16:00 |
| szaher | for storage reldan is using default value as swift | 16:00 |
| m3m0 | but the container default value will be freezer_backups when storing on swift | 16:01 |
| m3m0 | but what will be the default value for ssh and local? | 16:01 |
| reldan | There are no default for ssh and local | 16:01 |
| szaher | for ssh and local not done yet | 16:02 |
| szaher | I'll work on it | 16:02 |
| reldan | I just have no idea what we can use as default for ssh and local | 16:02 |
| reldan | /tmp ? ) | 16:03 |
| m3m0 | mmm | 16:03 |
| szaher | may be the home directory of the user | 16:03 |
| m3m0 | i don't think that should be the correct behaviour | 16:03 |
| szaher | and we use a folder called freezer_backups | 16:03 |
| szaher | ? | 16:03 |
| reldan | But it may be windows as well | 16:03 |
| reldan | yes - and it’s fails | 16:03 |
| m3m0 | because if you set 2 different backups without defining a container | 16:04 |
| m3m0 | those 2 could get corrupted isn't it | 16:04 |
| m3m0 | ? | 16:04 |
| reldan | I would prefer don’t have any default value | 16:04 |
| reldan | It’s strange actually | 16:04 |
| m3m0 | yeah kind of, to have only a default value for swift | 16:05 |
| reldan | And for me it is strange that we adding “freezer” prefix for swift | 16:05 |
| reldan | freezerc —path-to-backup … container = my-backups | 16:05 |
| fabriziov | yeah ... what about "frozen" ? | 16:05 |
| reldan | but actually it will store data in freezer_my-backups | 16:05 |
| reldan | Why? | 16:06 |
| reldan | I have no possibility to store my data in container without “freezer” prefix at all | 16:06 |
| m3m0 | #agree with that | 16:06 |
| m3m0 | we should find a better behaviour for that | 16:07 |
| reldan | Agree | 16:07 |
| * fabriziov agrees | 16:07 | |
| szaher | Okay, decision ? | 16:08 |
| m3m0 | so we agree that we should put a default value in containers? | 16:08 |
| reldan | I | 16:08 |
| m3m0 | shouldn't* | 16:08 |
| reldan | I’m not sure ) | 16:08 |
| m3m0 | me too | 16:08 |
| m3m0 | i think we shouldn't do that | 16:08 |
| fabriziov | default ok, forced value no | 16:09 |
| reldan | Default is strange for me ) | 16:09 |
| reldan | For swift we can imagine some funny name | 16:10 |
| reldan | But for other storages | 16:10 |
| szaher | container is a term used only for swift and not for ssh and local | 16:10 |
| reldan | But I actually don’t think that it is a major problem | 16:10 |
| szaher | so we will provide default value for container for swift only ? or we will make it mandatory for the user to enter a container name ? | 16:10 |
| reldan | It’s nice to discuss problem | 16:10 |
| fabriziov | default for ssh could be a folder in ssh_user's home | 16:10 |
| szaher | I suggested that before, but what about local ? | 16:11 |
| m3m0 | can we discuss this offline? | 16:12 |
| reldan | Yes, sure. I’m not sure that it has any significant priority | 16:12 |
| szaher | Sure | 16:12 |
| m3m0 | agree with that :) | 16:13 |
| m3m0 | so, szaher, you should go on with that | 16:14 |
| szaher | Okay, finally for containers I'll leave it as it's ? | 16:14 |
| m3m0 | with the default value | 16:14 |
| szaher | Yea | 16:14 |
| m3m0 | does anyone have anything more to add? | 16:15 |
| szaher | nope | 16:16 |
| m3m0 | nice :) | 16:16 |
| m3m0 | thanks to everyone | 16:16 |
