colin-backtracking on the iops thing, that (predictably) was not a factor after all17:56
johnsomDarn, hoped you had found an answer18:02
colin-did you say what version of ubuntu your amp was running? i can't recall if i asked18:09
colin-i assume they're the same18:09
johnsomThey were on 16.0418:10
colin-ok, same18:12

hyangHi there, I ran into some issue of using Queens Octavia with ipv6. In v4, it's all good, but when I create the amphora in v6 subnet and add vm with v6 address to the pool, healthcheck shows node online but I cannot use the vip_address to talk to my node. After login to amphora, I see the ifconfig are different in v6 and v4 and here is my paste  http://paste.openstack.org/show/731923/22:29
*** openstackstatus has joined #openstack-lbaas22:29
*** ChanServ sets mode: +v openstackstatus22:29
hyangso I want to know why in v4, the vip address is associated with an alias interface but in v6 it is added as the secondary address and shared the same interface with vrrp22:30
johnsomhyang Are you running with topology ACTIVE_STANDBY?22:31
hyangAlso my v6 subnet has /64 mask but looks like the v6 vip_address is associated the /32 mask, I don't know how this happened22:32
hyangjohnsom hi, no I'm using single mode22:32
johnsomHmmm, ok. In active/standby I know it is broken. I just put up a patch yesterday that fixes it.  https://review.openstack.org/#/c/589292/22:33
*** aojea has quit IRC22:33
johnsomThe /32 was also fixed in that patch.22:33
johnsomBut running in Single mode, I thought was working....22:34
hyangjohnsom could you plz point me where is fix for the /32?22:35
johnsomOh, I was thinking of a different fix where it was hard coded to /32 here https://review.openstack.org/#/c/589292/19/octavia/amphorae/backends/agent/api_server/templates/plug_vip_ethX.conf.j222:37
hyangjohnsom may I know why is it like <'128' if vip_ipv6 else '32'> in the change above?22:45
johnsomhyang as that is a policy based routing rule and the address there is a host address, not a network, that it should match.22:46
hyangoh, ok. But that should not affect why I got /32 mask in my ifconfig right22:48
johnsomhyang Correct, I was thinking of a different issue.22:49
johnsomI can test IPv6 in standalone here in about 15 minutes. I have to rebuild my devstack.22:50
hyangoh, that would be great, thank you22:51
openstackgerritCarlos Goncalves proposed openstack/octavia master: Delete zombie amphorae when detected  https://review.openstack.org/58750523:00
johnsomhyang Yeah, my standalone LB with an IPv6 VIP is working for me.  Note, I am on the master branch, but I don't think much has changed from queens in respect to the IPv6 support.23:15
hyangjohnsom so does your amphora got the vip_address with an alias interface or it is also a secondary address23:16
johnsomhttps://www.irccloud.com/pastebin/tmIxgTUy/23:17
johnsom6047 is the VIP23:17
hyangjohnsom may I know what you get for `ip netns execs amphora-haproxy ifconfig` ?23:21
johnsomhttps://www.irccloud.com/pastebin/xb5W1I3f/23:22
hyangand your v6 subnet is /64 right?23:23

johnsomhyang fd58:404f:7426::/6423:24
johnsomopps, wrong one,23:24
johnsomOh, nope, that is the right subnet23:25
*** aojea has joined #openstack-lbaas23:26
hyangok, thank you. Now I know my issue is not the interface alias but somehow Octavia set the v6 address with /32 while my subnet is /6423:26
hyangjohnsom do you have any thought how could it happen?23:26
johnsomhyang The other difference I see is that I'm using ubuntu amphora where you are using centos.  This could also be why we are seeing different results.23:30
johnsomIt looks like we get a netmask from neutron that is converted to the prefix in centos images. I wonder if that conversion is wrong or if the netmask we are getting is incorrect.23:31
hyangcould you plz point me with the code that does the logic you described? I can try debug it23:33
