anskiyhey! I do remember that quite some time ago you've been discussing some problems with galera, but I can't find that discussion right now. Currently, on my semi-production deployment I see this: https://jira.mariadb.org/browse/MDEV-25368. Is there some workaround for this in either of OSA branches, or I should just manually pin Maria to 10.5.6 (which, according to comments there should work fine)?12:02
noonedeadpunkanskiy: eventually every new release of mariadb nowdays is buggy...12:05
noonedeadpunkThe most working deployment I have now is with `galera_minor_version:12` `galera_major_version: 10.5` 12:07
anskiynoonedeadpunk: well, I see "deadlocks" on that version :(12:07
noonedeadpunkyou can actually just define these variables and run openstack-ansible galera-install.yml -e galera_upgrade12:07
noonedeadpunkthis could be workaround easily12:07
anskiynoonedeadpunk: yeah, that's what I did, gonna try 10.5.6 as per issue, I've linked12:08
noonedeadpunk`galera_wsrep_slave_threads: 1` shoudl fix that iirc12:08
noonedeadpunkhttps://jira.mariadb.org/browse/MDEV-22766 12:09
noonedeadpunkJust don't try 10.5.9 if I'm not mistaken12:09
noonedeadpunkbecause they break local root user privileges there12:09
anskiyoh, reading those comments... looks like whole 10.4 is buggy too. Guess, I'll stick with 10.5.6 for now, if that would work fine. Thank you!12:14
noonedeadpunk10.6.4 was also broken btw - can't recall now how exactly though...12:15

spateljamesdenton around17:03
jamesdentonbarely :) whats up?17:59
supamattjamesdenton: he logged off half an hour before you replied ;P18:18
jamesdentonwhoops!19:05
spatelhey19:07
spatelsorry i didn't see your mesg @jamesdenton 19:07
spatelmy IRC client won't notify until i am tagged :) 19:08
jamesdentonno problem19:49
jamesdentonspatel whats up?19:51
spateli am running production style load-test and see following on dpdk so trying to understand what does this means?19:51
spatelhttps://paste.opendev.org/show/810290/19:52
spateli have two PMD core assigned to thread 19:52
spatelone of core hitting 97% processing cycle 19:53
spateldoes that means my PMD CPU is busy and not handling traffic optimal way19:53
spatelmy load is around 500kpps UDP packets 19:56
spatelone more thing if i restart openvswitch-switch it make all my vm stopped pinging.. :(20:09
spatelso i have to shutdown all vm by hand and bring them up to fix it20:10
spateli thought ovs restart just blip networking but in my case it stop network until vm restarted 20:10
mgariepyhuh.20:10
mgariepythat's weird. 20:10
mgariepydid you try restarting neutron ?20:11
jamesdentonrestarting openvswitch-switch will clear all flows, but i would expect the neutron agent to notice and repopulate20:26
spateli restart whole bix 20:32
spatelbox20:32
spatelI did restart neutron also20:32
spatelbut no luck20:33
spatelmay be in DPDK case it different..20:33
jamesdentonperhaps. could be worth submitting a bug20:53
spateli will 20:57
spateljamesdenton do you know how to read this ? - https://paste.opendev.org/show/810291/20:57
jamesdentonno, i'm sorry20:57
spatelwhat are these queue-id ? and why only id=0 is in used 20:57
spatel:)20:57
jamesdentonall good questions20:58
spatelthinking this is my bottleneck 20:58
jamesdentonwhat chassis?20:58
spatelchassis?20:58
spatelThis is not OVN 20:59
spatelhttps://support.sonus.net/display/SBXDOC92/_OVS-DPDK+Virtio+Interfaces+-+Performance+Tuning+Recommendations20:59
spatellook like i have to do ovs-vsctl set interface dpdk0 other_config:pmd-rxq-affinity="0:8,1:26" 20:59
spatelassign queue to cores.. 20:59
jamesdentonsorry, what server hardware chassis. 21:01
spatelDell 440 PowerEdge 21:01
spatelIntel X550T 21:01
spatelCPU - Intel(R) Xeon(R) Silver 4214 CPU @ 2.20GHz21:02
spatelThis is how i am reading that output 21:02
spatelmy VM has 8 queue, i can see it in ethtool on vm21:02
spatelIn this output i can see 8 queues for each vm - https://paste.opendev.org/show/810291/21:03
spatelnow PMD default using only single queue which is 0 (zero)21:03
spatelif i map it with 8 queue then i have more opened LANE to push packet21:03
jamesdentonso many tunables21:04
spatelDPDK is not worth :(21:04
jamesdentonwell, maybe once you get it worked out it will be21:04
spateldamn 100 of option and this is not something you do in production 21:04
jamesdentonprobably best for specific applications vs general purpose21:04
spatelYes... 21:09
spatelalso i am surprised not enough good document outside.. world.. everyone saying just try this and that 21:10
spatelno wonder why people by default using DPDK if its so great21:10
