sean-k-mooneyset it to 30days and you get hits14:57
artomAh yes, indeed. I feel like we've hit this before, for a different job14:58
artomgmann ^^ sound familiar?14:58
sean-k-mooneywe have hit this many times14:58
sean-k-mooneyits a tempest bug14:58
sean-k-mooneythe tests are not wrtten correctly14:58
artomI kinda figured that already :P14:59
artomI was looking for a previous fix that I could plagiarize to avoid having to think about this ;)14:59
artomOr to straight up "delegate" to someone else :P14:59
sean-k-mooneythe first failure was in this requiremnt update to neutron libs https://review.opendev.org/#/c/74523715:01
sean-k-mooneythat may or may not be related to the cause15:02
*** mlavalle has joined #openstack-nova15:10
gmannartom: sean-k-mooney yeah, we fixed this issue while we see error.15:12
artomgmann, do you remember what the fix was? Do we need to redo it somewhere else?15:15
*** JamesBen_ has joined #openstack-nova15:16
gmannby default, tempest tests does not pass the dedicated network while creating server so we go test by test and request for unique network to be created for test15:16
gmannartom: yeah15:16

gmannartom: https://review.opendev.org/#/c/721767/15:17
*** songwenping_ has joined #openstack-nova15:17
gmannwhich test failing?15:17
artomgmann, looks like we're hitting it in tempest.scenario.test_server_advanced_ops.TestServerAdvancedOps.test_server_sequence_suspend_resume15:18
artomAnd something else, but I can't figure out the test from the kibana info15:18
gmannartom: ah that is scenario test which always has the unique network, let me confirm15:19
sean-k-mooneythere are a number of test failing15:20
*** songwenping__ has quit IRC15:20
sean-k-mooneytempest-AttachInterfacesTestJSON tempest-test_creds-167978404015:22
gmannfor API tests, root cause is same and we can fix it in Tempest side15:22
sean-k-mooneyactully i need to filter out passing jobs15:23
sean-k-mooneyapparently we have some tests that try to create that error15:23
artomsean-k-mooney, ah, it would explain why https://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_1a8/744280/6/check/nova-next/1a8a26e/controller/logs/screen-n-api.txt is from a passing job15:24
artomI guess start by fixing test_server_sequence_suspend_resume then?15:24
sean-k-mooneyoh so 212 hits instead of ~50015:25
sean-k-mooneyand some of those have failure that are not related to this15:26
sean-k-mooneythis will be annoying to fine a query for15:26
gmanntest_server_sequence_suspend_resume  does not explicit create the network and test try to get one from neutron - https://github.com/openstack/tempest/blob/master/tempest/scenario/manager.py#L25715:26
gmannartom: the fix i mentioned will not help for test_server_sequence_suspend_resume , we need to do either create the network explicitly or add some common logic in scenario manager also like we do in API test15:27

sangeetI need help. I am doing "nova-manege db sync" and it faile with error "ERROR: Could not access cell0.". "nova-manage cell_v2 map_cell0" "nova-manage api_db sync" were run successfully before. I have ssl enabled in my deployment. The issue seems that _url_cfg.connection in _TransactionFactory object is somehow not corect for nova_cell0. Hence the DB is rejection the connection. Please see http://paste.openstack.org/show/796820/.17:17
sangeetBut connection in [cell0_database] in nova.conf is set correctly. Where is _TransactionFactory object reading the connection value form?17:17
sean-k-mooneysangeet: your the second person to ask abou this in 2 hours :)17:19
sangeetInteresting17:19
sangeetsean-k-mooney was it answered? Sorry I can not scroll up for previous chats.17:20
sean-k-mooneyam no17:20
sean-k-mooneysame bhavior "nova-manage --debug  api_db sync and nova-manage --debug  cell_v2 map_cell0" bot worked by sync failed17:20
sangeet:-(17:21
sean-k-mooneyi think if you want to run sync on cell017:21
sean-k-mooneyyou need to create a second config adn set teh database connection to point to cell017:22
sean-k-mooneyat least i think you had to do that in the past e.g. nova-manage did not read cell0_database17:22
sean-k-mooneybut i could be miss remembering17:22
sangeetThat is waht I have set .. please look at http://paste.openstack.org/show/796820/.17:23

sangeetsean-k-mooney - Please not .. if I do a new openstack deployment with ssl it is working fine. Its only when I am doing an update from no ssl to ssl, I see the issue. Somehow url_cfg.connection in _TransactionFactory object  is taking old connection17:26

sean-k-mooneyas i said that config option is not valid. no code in nova exits to use it17:48
sean-k-mooneywehn you dont pass --loca_cell we lookup the cell0 from the db17:48
sean-k-mooneyhttps://github.com/openstack/nova/blob/master/nova/cmd/manage.py#L188-L18917:48
sean-k-mooneyso unless you have updated the cell0 database connection string in the cell maping table it will use the old value17:49
sean-k-mooneysangeet: if you pass --local_cell it will skip that lookup although it wont update the schem of cell017:50
sean-k-mooneyyou will have to do that manually17:50
sangeetIt is automated but let me try manually17:50
sean-k-mooneybut ya in anycae openstack helm has a bug17:50
sangeetyou are saying run nova-manabe db sync --local_cell?17:50
sean-k-mooneyyes17:51
sangeetLet me try that real quick17:51
sean-k-mooneyopenstack helm is not generting correct local.confs and as a result the automated db sync will fail if you are going form non ssl to ssl17:52
sean-k-mooneysince it will use the non ssl connection string from the db17:52
sangeetawesome ... that worked. Can you please explain what --local_cell opetion does17:52
*** priteau has quit IRC17:53
sean-k-mooneyit tells nova manage not to lookup the db connection string form nova_api.cell_mappings db table17:53
sangeetInterestinfg17:53
sean-k-mooneyyou need to run nova-manage db sync on one contoler on each cell wehn you use --local-cell17:54
sean-k-mooneysangeet: alternitvily you can just update teh connection string in the cell mappign table in the nova_api db17:54
sean-k-mooneyin my devstack deployment its just mysql+pymysql://root:password@127.0.0.1/nova_cell0?charset=utf817:54
sean-k-mooneybut you would need to add the ssl parmater to your version17:54
sangeetLet me see what I have in the my database17:55
sean-k-mooneymysql -e "select database_connection from nova_api.cell_mappings where name='cell0';"17:56
sean-k-mooneyby the way you should not really paste the result publicy17:56
sean-k-mooneysince it has the password in it...17:56
sean-k-mooneyanyway it does not have the ssl cert info right17:57
sangeetYou are correct .. it is without ssl17:57
*** songwenping_ has joined #openstack-nova17:57
sean-k-mooneyyep so you could just update it and then it would work17:57
sangeetgoing back to useing --local-cell, do you see any issue with it? Also when you say "you need to run nova-manage db sync on one contoler on each cell wehn you use --local-cell"17:59
sean-k-mooneyby should work i mean nova manage shoudl work without --local-cell and as a result the automated update should work too17:59
sangeetdoes it mean I have to run on each node17:59
sean-k-mooneyno so each cell has its own db right17:59
sangeetyes18:00
sean-k-mooneyso each cell db needs to be updated18:00
sean-k-mooneywehn you use --local-cell it only update well the locall cell db18:00
sean-k-mooneynot all deployment have db access between cells18:00
sangeetwill "nova-manage db sync  --local-cell" not update all cells?18:00
*** songwenping__ has quit IRC18:01
sean-k-mooneycorrect it only updates the cell pointed to in the database section18:01
sangeetbut "nova-manage db sync " does all?18:01
sean-k-mooneyactully no18:01
sean-k-mooneyit does the local cell and cell018:01
sean-k-mooneyyou need to run nova-manage in each cell anyway18:02
sean-k-mooneyhttps://github.com/openstack/nova/blob/master/nova/cmd/manage.py#L185-L18618:02
sangeetSo it mean I run the command with our without   --local-cell, it will update same cells?18:03
sean-k-mooneyno the default behavor is to update the cell in [database]/connection and cell018:04
sean-k-mooneyso if you run the command on the host with the conducto for cell1 it will update cell1 and cell018:04
sean-k-mooneyran on the host with the conductor for cell2 it will update cell2 and cell018:05
sean-k-mooneyif you add --local-cell it will skip updating cell018:05
sean-k-mooneyunless [database]/connection point to cell018:05
sean-k-mooneybasically the nova.conf used by the nova api should have [database]/connection pointing at cell0, each conductors nova.conf should have [database]/connection pointing at the cell db18:06
sean-k-mooneyand the compute services should not have the database details defiend at all18:07
sean-k-mooneyopenstack helm shoudl then be automatinn runing the db sync once for each cell db using the correct cofigs18:08
sean-k-mooneyand the simplet way to do that is to delegate runing nova-magange db sync to the first conductor host in each cell18:08
sean-k-mooneyyou can safly run it on each conductor host18:09
sean-k-mooneyas it is not destructive its just wasteful to do it18:09

eanderssonbtw I have a PR open for cloud-init for the OpenStack Datasource to increase the retry limit when identifying the metadata service. The current defaults only allows a single failure before giving up. https://github.com/canonical/cloud-init/pull/50121:29
