jseilerganso: vponomaryov: My manners are bad, I forgot to thank you for the help you gave me the other day in getting the tempest tests to run against my new driver. So a belated thank you to you both.15:16
jseilerI'm developing a new manila driver for ocata and am trying to run the tempest scenario tests under devStack.15:17
jseilerI've been trying to follow these instructions for running the tests- http://docs.openstack.org/developer/manila/devref/tempest_tests.html15:17
jseilerAnd have been referencing the test config options here - https://github.com/openstack/manila/blob/master/manila_tempest_tests/config.py15:17
jseilertest_mount_share_one_vm test is failing with the error:15:17

jseilerThe 192.168.0.35 is the address of my file system.  I was wondering if there is something additional I need to configure for neutron to know about the 192.168.0.x (external) network?15:17

gansojseiler: hi15:43
gansojseiler: it is very good that you are running scenario tests15:43
jseilerganso: hi15:43
gansojseiler: it seems the network path from your host or tempest server to your floating IP network is not configured correctly15:44
jseilerganso: So, is the purpose of the scenario tests to create a share on the file system, then actually read and write data to the share?15:44
gansojseiler: tempest.lib.exceptions.SSHTimeout: Connection to the 172.24.5.3 via SSH timed out.15:44
gansojseiler: 172.24.5.3 is a floating IP, I presume15:44
jseilerganso: yes15:44
gansojseiler: so, this is one problem15:44
jseilerganso: Yes, we were wondering if we need to configure something more for neutron.15:46
jseilerganso: And maybe specifically, how does routing get setup to the external subnet where our file system is located.15:47
gansojseiler: this error: 'sudo mount -vt nfs "192.168.0.35:/149a3496_820c_468d_8627_714b633071fc/" indicates that the floating IP error above did not occur for this test... but then the VM could not reach your storage, again, you perform the steps of this test manually and validate if a VM can reach the storage. Maybe it is the network tempest is choosing that15:47
gansodoes not reach the storage, in that case, there is a config option to use a specific network, you can look for it in config.py and set it tempest.conf in [share]15:47
gansothird 2016-08-05 10:36:57.763 24087 ERROR manila_tempest_tests.tests.scenario.manager_share User: manila, Password: None15:47
gansojseiler: ^ the scenarios test are probably using the manila-service-image, in that case, I believe you need to set the password, if for some reason the ssh key did not work. the password is manila, take a look in config.py if there is an option for that15:48
gansojseiler: image_password15:49
gansojseiler: share_network_id15:49
jseilerganso: I did something in the logs about manila-service-image. What are those for and where are they stored?15:51
jseilerganso: I was wondering if they were stored on the generic1 share backend that is configured by default in devStack15:52
*** faiz89 has quit IRC15:52
*** narayrak has quit IRC15:54
*** dsariel has quit IRC15:55
gansojseiler: you are disabling the generic1 backend and enabling only your drivers', right?15:56
jseilerganso: I did originally. Not today. I left the generic1 driver thinking the images may be store there.15:56
jseilerganso: So I should remove the generic1 from manila.conf then - right?15:57
gansojseiler: yes16:05
*** pcaruana has quit IRC16:05
jseilerganso: Thanks. I did that, set the image_password = manila.  Am running the tests again. I'll see if that corrects one problem.  I think that will leave what I need to do to configure a network to access my file system.16:07
gansojseiler: you're welcome16:08
jseilerganso: Where are you located? I was just wondering your work hours.16:09
jseilerganso: OK, after configuring image_password, both scenario testsfail with the error:16:13

gansojseiler: ok seems that you can connect to the instance, so you may not have floating IP problems, or they are random, and it seems now you don't have password problems anymore16:15
gansojseiler: so you have only 1 problem to figure out16:15
jseilerganso: So I think that means I need to configure a network for where my file system is located, then configure that network id in manila.conf, [share] share_network_id  ?16:15
*** Suyi_ has joined #openstack-manila16:15
gansojseiler: I suggest you create a neutron network, share-network, boot an instance, test if you can mount shares from your storage, and then use that share-network in the share_network_id in tempest.conf [share]16:16
jseilerganso: OK. Thanks. I will try that. I'm still new to this so I'll need to figure out how to do all that. I'll check for some youtube videos. I found some on neutron that helped explain the higher level concepts.16:20

vponomaryovganso: why migration_start is executed on src host?16:41

*** akerr is now known as akerr_away16:43
*** akerr_away is now known as akerr16:43
gansovponomaryov: I haven't looked much into replication, why is that?16:43
vponomaryovganso: because changes are going to be there16:45
vponomaryovganso: but in best case we should use RPC from one to other saving intermediate things in DB16:46
vponomaryovganso: it will mean we have "dst-" only migration methods in share managers as well as "src-" only16:47
vponomaryovganso: right now, I workaround lack of such feature by using ssh connections16:47
gansovponomaryov: a certain level of communication between the two backends is expected16:48
gansovponomaryov: not all backends are expected to create a copy of a share when migrating16:49
gansovponomaryov: some can actually move data efficiently16:49
vponomaryovganso: in that case some methods could be just empty16:49
gansovponomaryov: so if it was in dest, it would have to pull data, in src it pushes data, it does not matter much16:49
vponomaryovganso: feature design should consider such big case16:50
vponomaryovganso: also, implementing it I came to idea that we should have "migration_domain", the same thing we have in replication feature16:51
vponomaryovganso: I should be able to segment migration relations16:51
vponomaryovganso: now I can too, but not using common mechanism, only using driver-specific things16:52

vponomaryovnow you have feedback16:53
vponomaryov))16:53
gansovponomaryov: I acknowledge it may not work for every vendor, but then we would get more vendors involved to tailor the design to work with everybody16:53
gansovponomaryov: yes, this is very good16:53
*** akapil has quit IRC16:55
gansovponomaryov: I am not sure we will be able to work on an improved design right now, if it can be done with a proper driver interface and what we have today it is good so we have some experience and work from there, like replication did in mitaka16:56
vponomaryovganso: not now, ocata maybe16:56
gansovponomaryov: I am glad you can at least sort it out using driver-specific things, that's a good start because you are finding out elements that you need and that could be integrated into manila16:57
vponomaryovganso: my point is make each driver talk to its storage itself instead of making each of them to talk to all16:57
gansovponomaryov: could be, we need more data on that for different vendors as well. I hope more vendors get involved16:59
