rm_workAh, so in the meeting, you guys were talking about Barbican vs Castellan etc19:41
johnsomYep, decided to ditch it all and go native vault19:41
rm_workwe don't use Castellan but we use a Castellan-like interface which supports adding any other drivers easily, so there is no reason we would have to consider switching how we did things lol19:41
johnsomGrin, just kidding19:41
rm_workwe can add whatever extra drivers we want19:41
rm_workthe thing we use already serves the same purpose as Castellan (and I still wish they would have accepted it INTO Castellan but alas...)19:42
rm_workI can try to propose it again, now that they have given control of the project to oslo19:42
rm_workand maybe the oslo folks won't be so oddly opposed to including it19:42
johnsomYeah, I think the summary of the discussion was nobody cares enough to change anything at the moment19:42
johnsomrm_work of more interest, we agreed to open up merging for Queens, so enjoy...19:43

xgerman_johnsom I changed the DIB code and now see:20:11
xgerman_https://www.irccloud.com/pastebin/VVQXx77Z/20:11
johnsomHmm, wasn't that what we had before?20:12
xgerman_our life is circular20:12
xgerman_before we had some local variable which didn’t like us20:13

xgerman_ok, that digraph comes from the illautsious networx package which updated from 1.10 to 2.0b120:38
xgerman_a week ago20:38
johnsomMaybe run with that trace flag and share the output?  I can dig through it with you20:38
xgerman_pretty sure that nrtworkx update is a smoking gun20:39
xgerman_a major version jump after 3 years…20:39
johnsomSo are you somehow not using upper constraints?20:39
xgerman_maybe ansible ignores them?20:40
openstackgerritMerged openstack/python-octaviaclient master: Remove positional from requirements  https://review.openstack.org/49646720:52
xgerman_ok, it’s not in the cosntrained file21:06
xgerman_I am blind21:07
johnsomLooking at the translation job it appears to be pulling 1.1121:13
johnsomBut, maybe that is for *inside* the image and not outside where DIB is using it...21:13
xgerman_I had 2.2b on my box21:18
xgerman_but I now hacked constraints on it21:18
xgerman_so let’s see…21:18
*** gcheresh_ has quit IRC21:20
*** leitan has quit IRC21:22
xgerman_worked: https://review.openstack.org/#/c/496929/21:27
johnsomNice, so now we just need to worry about when networkx 2.x comes in21:28
xgerman_yep21:28
*** atoth has quit IRC21:29
johnsomxgerman_ Maybe file a bug against DIB?21:32
xgerman_maybe,…21:34
johnsomThat way they will be aware and maybe can start working on it21:35
xgerman_on another note how many backups can you have with keepalived? 10, 20?21:35
xgerman_k, will file bug21:35
johnsomhundreds if you can think of a use case21:35
xgerman_my wacky ACTIVE/ACTIVE21:37
rm_worklol21:37
rm_worki wish i knew why keepalived suddenly takes 4s to detect a failure T_T21:37
xgerman_apparently iptables has nt only a statistics module but also a recent one - so it can do session persistent forwarding21:37
*** aojea_ has joined #openstack-lbaas21:38
xgerman_now, you will still have the 4s downtime when the VIP switches but otherwise you could use all the backup LBs for laod balancing21:38
johnsomHow do you folks feel about backporting a docs change into stable/pike?21:38
*** aojea has quit IRC21:39
openstackgerritMichael Johnson proposed openstack/octavia master: Add a CLI section to the Octavia docs  https://review.openstack.org/49694021:39
rm_work:thumbsup:21:40
johnsomIt would be spiffy to have our docs point to the CLI we added in pike21:40
*** tongl has joined #openstack-lbaas21:43
tonglHi, if the resource creation is passed down to driver, can we alway assume all the params pass the validation already. e.g. create a l7 rule with invalid compare_type 'BAD', this wouldn't go to driver as it failed validation already?21:45
johnsomhttps://review.openstack.org/#/c/496940/ and https://review.openstack.org/#/c/496941/21:45
johnsomtongl Correct21:46
johnsomAssuming there aren't bugs or validations missing21:46
tonglGreat :), then in the driver, we won't need worry about common validation anymore.21:47
tongljust consume it21:47
tonglI noticed another behavior. if there is anything wrong with the child resource, it will put the loadbalancer to ERROR state. e.g. lb has 3 listeners/pools, if adding another member to one pool failed, it will put loadbalancer to ERROR. does that mean if any child resource goes wrong, the whole loadbalancer stop working?21:49
tonglAnother question is if loadbalancer is in ERROR state, how do we recover it? It seems we cannot delete it if it is in ERROR state.21:50
johnsomThis is an area neutron-lbaas does not handle well.  We have made a number of attempts to address that with octavia21:52
*** aojea_ has quit IRC21:52
tonglCurrently I just login to db to update state to ACTIVE and then delete it. Not sure if there is any better way to work around.21:54
johnsomYou *should* be able to delete any object in ERROR.  You may need to use the cascade delete.  But, with neutron-lbaas, there might be issues.21:56
*** armax has quit IRC22:03
rm_workyeah so I think the MEMBER is supposed to go to ERROR but I didn't think the LB or other objects were22:23
rm_workthat might be a bug?22:23
rm_workyou're supposed to just be able to delete the member and try again22:23
tonglI tried with l7 rule, there is any exception during l7 rule creation. but the l7 rule is created, but loadbalancer goes to ERROR state. there is no provision_state for l7 rule.22:30
*** leitan has joined #openstack-lbaas22:32
rm_workweird22:32
rm_workoh22:32
rm_worklol yeah uhhh22:32
rm_workneutron-lbaas is dumb in some cases22:32
rm_workit doesn't have provisioning status for all objects22:32
rm_workwe fixed that in Octavia...22:32
johnsomRight22:32
tonglcannot wait to work on Octavia driver :)22:35
