jrosserhmm seems like the dashboard does not work unless you are logged into gerrit09:21
jrosserthats sad for end users vs. contributors09:21
kleinispatel, ThiagoCMC: I use live migration even with local block storage on compute nodes. but that requires block-migration, which one works if you turn of libvirt live-migration-tunnelled. VM is then migrated without using an encrypted connection, but that is okay for me.09:35
noonedeadpunkprobably can be resolved by some permission given to all-projects10:19
jrosseri added it as an issue to the infra migration etherpad so hopefully someone can take a look10:34

kleiniAFAIR block migration just failed for me with tunnelled transport, which is by default deployed with OSA. So, my solutions was to overwrite this OSA default setting. That's all.14:39
spateljamesdenton: I am having hard time to run Trex :(14:41
spatelI am having some ARP issue, my RX end not receiving any packet and openstack instance saying arp incompletion14:42
spatelLook like i have switch fabric between VM and my Trex server so wondering if Trex GARP not handing it properly14:43

openstackgerritAndrew Bonney proposed openstack/openstack-ansible master: Update variables for default Zun AIO  https://review.opendev.org/c/openstack/openstack-ansible/+/76356215:18
ThiagoCMCSorry for the Ceph question but, do you guys knows how to fix this warn:15:18
ThiagoCMC8 OSD(s) have broken BlueStore compression ?15:18
ThiagoCMCI tried to disable it and now I think that I lost my cluster lol15:19
ThiagoCMCIt was too slow15:19
jamesdentonspatel i believe you can manually configure ARP entries15:20
spateljamesdenton: i did on VM but still my RX end not seeing any packets15:20
spatelhttps://ibb.co/T4jBcBP15:20
spatelI am not running Trex in DPDK mode so i am able to capture TCPDUMP and found Trex sending UDP stream but RX end not receiving any packet15:21
spatelsame time when i run tcpdump VM. its showing sending UDP to mac address of Trex which is correct15:22
spateljamesdenton: did you run Trex across switch Fabric or using direct cross cable?15:24
spatelI heard people saying Trex don't use GARP so for middle switch its hard to figure out15:24
openstackgerritAndrew Bonney proposed openstack/openstack-ansible-os_zun master: DNM: Update zun role to match current requirements  https://review.opendev.org/c/openstack/openstack-ansible-os_zun/+/76314115:27
jamesdentoni know i've done cross-connect, can't recall if i did it thru a switch15:37

admin0jrosser, https://github.com/openstack/openstack-ansible-os_octavia/blob/master/tasks/octavia_mgmt_network.yml  -- octavia_neutron_management_network_name, provider type etc ... is it just like another ext-net ?17:43
admin0we give it in the variables and it will create automatically ?17:43
*** nurdie has quit IRC17:43
*** nurdie has joined #openstack-ansible17:45
admin0can we provide details to a pre-created one ? and also , is that network that runs over  br-vlan or is it over br-lbaas17:47
mgariepynoonedeadpunk, jrosser, jamesdenton have you seen cinder-api not restarting on config change ?18:17
noonedeadpunkyep and I think I've placed a patch to cover that and it has merged a while ago18:18
noonedeadpunkhttps://review.opendev.org/q/Ie1f386f21b955dcc1d2450efa9391c56d05d569518:18
mgariepywow the new gerrit is so weird haha18:19
noonedeadpunklol, yes18:19
noonedeadpunkI'm using it for half a year I guess internally and still takes time to find things I need18:20
noonedeadpunkie check patchset or in which branches/tag patch is included18:20
jrosseradmin0: it is just another provider network and you can have the Octavia ansible role create it, or do it yourself, up to you18:20
*** cshen has quit IRC18:25
admin0jrosser, but those need to be specified in the user_variables right ?19:04
admin0this completely omits this part: https://developer.rackspace.com/docs/private-cloud/rpc/master/rpc-octavia-internal/octavia-install-guide/19:05
jrossersome of the info goes in the service config file19:06
jrosserso yes some fields are necessary19:06
jrosserbut the creation is optional19:06
admin0the playbook fail in the middle parameters are required together: allocation_pool_end, allocation_pool_start19:17

MickyMan77Hi all, What does this means ? "Error during database migration Database schema file with version 140 doesn't exist" I did get this when I did rerun setup-openstack.19:36
MickyMan77the error was under task, "os_cinder : Perform a cinder DB sync"19:36
MickyMan77How do I get around the issue ?19:36
*** andrewbonney has quit IRC19:44
jrosseradmin0: only if you ask it to create the network https://opendev.org/openstack/openstack-ansible-os_octavia/src/branch/master/tasks/octavia_mgmt_network.yml#L7719:44
jrosseri'm not sure if you think there is a bug here or not?19:45

spateljamesdenton: i think i am going to give up on Trex :(20:12
jamesdentoni remember it being... tempermental20:12
spatelNot able to solve that issue (or may be i don't understand what is going on)20:12
jamesdentonbut it was not TRex fault, but tricky to get right20:12
spateljamesdenton: totally understand i can see everything looks good but still my packet not reaching to RX end20:13
spatelping is working but not scapy packets20:13
spatelif you want i can screen share with you :) if i am doing something stupid20:14
*** jhesketh has quit IRC20:16
jamesdentondon't really have any time right now, sorry :(20:17
spateljamesdenton: any other tool which can generate enough amount of packets because i don't want to spend any time on Trex20:18
spateli can use hping3 may be20:18
jamesdentonwell, how did you evaluate performance of SR-IOV?20:19

spateljamesdenton: just use nuttcp20:23
admin0{"attempts": 5, "changed": false, "msg": "parameters are required together: allocation_pool_end, allocation_pool_start"}  -- i tried allocation_pool_start as well as octavia_allocation_pool_start .. but it does not seem to pick up20:23
spatelbut i don't think nuttcp is real way to reach high PPS20:23
admin0jrosser, -- got it20:24
jamesdentonadmin0 set octavia_service_net_setup: False20:24
admin0just did that20:24
admin0i read every line.. except that last line :(20:25
admin0spatel, my office uses trex a lot20:25
admin0tomorrow i will gather some info for you20:25
spateladmin0: really, Please help me out :)20:26

jamesdentonthat's an ansible warning, iirc21:41
spateljamesdenton: i found Trex problem :)21:43
jamesdentonwhat was it?21:43
spateldon't tell me what is the issue.. haha21:43
jamesdentonoh, one of those :D21:43
spatelIt was openstack host iptables rules stopping ARP to go cross interface21:43
jamesdentonpebkac21:43
jamesdentoninteresting21:44
jamesdentonwell, glad you found it!21:44
spatelI did, i think problem was i was testing standard VM box for testing but look like that VM box used bunch of iptables rules on host machine21:44
spatelIf i use DPDK or SRIOV then it will by pass iptables and it won't create any issue21:45
spatelI am digging into iptables rules to find out which one was causing issue because it has tons of rules.21:45
