masbergood afternoon, I am wondering if this is a typo https://docs.openstack.org/project-deploy-guide/openstack-ansible/pike/overview-requirements.html says VLAN offloading, which increases performance by adding and removing VLAN tags in hardware, rather than in the server’s main CPU...02:54
masberI have searching on internet and I can't find the way of doing VLAN offloading in my nics so I was wondering whether this really means VXLAN offloading?02:54

evrardjpmaybe worth cleaning your nodes, and start from scratch, and tell us what you do in the full process, maybe there is something you're missing from our docs, or something is missing in our docs08:24

evrardjpfoutatoro: generally swift is with local things, we do not do ceph + a swift gateway IIRC.13:17
evrardjpmaybe worth checking what you can do with ceph-ansible, because that's what we are using to deploy ceph, behind the scenes13:18
evrardjpour swift role is doing everything locally if I am not mistaken. andymccr could help you more there13:18
foutatoroevrardjp: since ceph has an object storage feature I wondered if this could be used by swift to avoid having to types of storage nodes (swift servers + ceph servers)13:22
evrardjpfoutatoro: yeah. Using rados directly. Like I said, it's maybe possible using ceph-ansible13:25
evrardjpI don't know ceph-ansible enough13:25
evrardjpI guess it would make sense to configure a "middleware" in ceph that speaks swift and stores blobs into rados13:26

MikeWHey this isn't directly related to OSA, but you guys are all very very experienced... and I'm a dumbie a lot of the time... anyway can anyone point me to a guide that shows me how to push logs to graylog without having duplicates on host? Everything I've found just rotates locally into zipped files and pushes them to graylog15:44
jafehaMikeW, we have set the rsyslog_client_user_defined_targets within the osa deployment and ship logs to graylog via rsyslog. i cannot remember how graylogs side is configured, but we have no duplicates so far.15:47

cloudnullthe ceph-ansible playbooks should be able to stand up rgw19:16
cloudnullwhich you can integrate into openstack19:16
ivveaye manually19:16
cloudnullbut im not aware of anything we have that would do it automagically19:16
ivvei was thinking like with cinder19:16
cloudnullall you should have to do with that is define the cinder backend in the openstack_user_config.yml which points at ceph.19:17
ivveintegrate a working ceph cluster with keystone/swift endpoints19:17
cloudnulllike so https://github.com/openstack/openstack-ansible/blob/master/etc/openstack_deploy/openstack_user_config.yml.example#L673-L69019:17
ivveaye that i know of19:17
cloudnullok.19:17
cloudnullbeyond that I'm not sure.19:18
ivvei was thinking about something similar to that, but for keystone/swift endpoints for ceph rgws19:18
cloudnull^ mattt logan- andymccr ?19:18

* cloudnull still still with holiday brain19:20
ivvehah i thought it was with an intended pun :P19:20
cloudnullI'm not that clever19:21
cloudnullRandomTech: that should be all that's needed when integrating ceph with block storage19:21
cloudnullbut truth be told I've not worked much with ceph19:21
RandomTechand ive noticed that block isnt in the ceph example: https://docs.openstack.org/project-deploy-guide/openstack-ansible/pike/app-config-prod-ceph.html19:22
ivvei've worked with ceph, perhaps i can help19:22
RandomTechthat would be great, weve been pounding or head against the wall. would you like to look at our error and configs?19:23
ivveis it deployment with cinder+ceph?19:23

RandomTechwe tried to deploy it using opesntack ansible19:23
ivveshould be easy19:23

ivveaye, a ceph command19:26
RandomTechone moment while i compile those19:27
ivvecool19:27

RandomTechwe think it may have been a problem with the setup though19:35
RandomTechbecause we have been getting there error since it was set up19:35
ivvebasically ceph keyrings are not distributed19:36
RandomTechim not sure why19:36
RandomTechbut i guess so19:36
ivveill see if i can find the task in the playbook, im guessing its not using ceph-deploy19:37
RandomTechi do not know much about ceph. im a college student that was asked to setup openstack19:37
RandomTechthanks for trying to help us19:37
ivve:)19:38

jrosserheres a ceph/swift integration worked example https://keithtenzer.com/2017/03/30/openstack-swift-integration-with-ceph/19:39
jrosserseems like quite low hanging fruit for adding to OSA19:39
hamza21http://paste.openstack.org/show/638295/19:40
ivvejrosser: aye thats why i thought it was already in19:40
*** poul has joined #openstack-ansible19:40
jrosseryes it surprises me it isnt given how many OSA+ceph users there seem to be19:40
ivveRandomTech: to start with ceph_osd_hosts is only 2x hosts19:40
RandomTechivve: this is what is in there: http://paste.openstack.org/show/638296/19:40
ivveshould be 3 assuming its using default size = 3, min_size = 219:41
RandomTechwe only have 2 because we currently have 5 blades 3 of which need to be infrastructure/controll.19:41
*** DimGR has joined #openstack-ansible19:42
RandomTechas far as ive understood anyway19:42
ivvei suggest you put 3 of 5 as infra and 5 of 5 as compute if you can..19:42
ivvecolocate19:42
RandomTechmake them all act as compute?19:43
ivveaye19:43
RandomTechit wont cause any problems with three of them doing all the infrastructure?19:43
ivvebut not sure how to config that with osa (for ceph). not sure how it identifies block devices for ceph19:44
ivvewell i have 3 nodes here right now that acts everything19:44
ivveboth ceph, compute and controller :)19:44
ivvethey all contain mon processes and osds19:44
ivvei guess im not the best man for the job to assist with osa-ceph deployment.. im more osa+existing ceph :)19:45
RandomTechwould it help if i explain what we have to work with some.19:45
ivvesure19:45
DimGRhi19:46
RandomTechwe have 5 nodes for the cluster and one for deployment/monitoring, these 6 nodes have a 10Gb connection on an isolated network, and a 1Gb connection on a public network of a university19:47
ivvebasically it seems like you are missing ceph.client.admin.keyring19:47
ivveit should be somewhere as it is created early on19:47
ivveif that is the only issue then its quite easy19:47
RandomTechcould that be because ceph was not mentioned in group binds?19:48
ivvebut i suspect its not19:48
RandomTechya only the client keyring is in there19:48
ivveon the deployment node "find / -iname "ceph.client.admin.keyring" :P19:49
ivveim guessing its there, possibly in /etc/openstack_ansible/* ?19:49
*** gkadam has quit IRC19:49
ivvei see, using ubuntu or centos?19:51
RandomTechwere using ubuntu 16 and hers the output of that command: http://paste.openstack.org/show/638303/19:51
ivvegood guess there :P19:52
RandomTechhamza21:could that be what caused the keyring to not get distributed19:52
ivvefor i in blade1 blade2 blade3 blade4 blade5; do scp /etc/openstack_deploy/ceph-fetch/db5a73f2-56f1-4e55-8265-6489bb133b95/etc/ceph/ceph.client.admin.keyring root@${i}:/etc/ceph/ ; done19:53
ivvereplace blade with actual names19:53
ivveor ips19:54
ivveand input whatever passwordrequests come up for root user assuming thats allowed19:54
ivvelots of assumptions here :P19:54
RandomTechthere is no root password and we need to fix the setup so that we can reinstall stuff19:55
RandomTechand have a nice clean install19:55
ivveait19:55
ivveanyways, getting those keys to /etc/ceph on each node might help a bit but most probably not all the way19:58
hamza21RandomTech, not sure if group_binds could impact keyring, but clearly you need to add the ceph service to that group,19:58
ivveon the deployment node you could always check if ceph-deploy package is installed19:58
hamza21i deployed ceph-osa 8 months ago let me review my conf....19:59
RandomTechi just added ceph-osd to the group to match the example here: https://docs.openstack.org/project-deploy-guide/openstack-ansible/pike/app-config-prod-ceph.html20:00
RandomTechthank you hamza2120:02
ivveRandomTech: remember to add 3 hosts for osd20:02
ivve2 wont suffice20:03
RandomTechwill adding the infrastructure host as osd host as well cause issues?20:03
ivvehard to tell as i have never tried, but shouldn't be an issue20:04
ivvethey have a lot of host in the example20:04
RandomTechya :/20:04
RandomTechi wish there was a list of requirements with it20:04
hamza21RandomTech: we integrated ceph and rgws with osa, we used https://github.com/ceph/ceph-ansible , here is our working  openstack_user_config.yml :20:05
*** chhavi__ has joined #openstack-ansible20:05
ivveif you could supply 5 clean ubuntu hosts and a deployment node which has access to those i could probably deploy it quite quickly. can't do it until saturday though. CET timezone here20:06
ivvehowever i would deploy ceph with ceph-deploy and then osa for openstack20:06
hamza21RandomeTech : http://paste.openstack.org/show/638325/20:07
hamza21we also installed rgws and keyston in the same container, like this :20:08
hamza21http://paste.openstack.org/show/638327/20:09
hamza21here are the ceph variables that we used :20:10
hamza21http://paste.openstack.org/show/638331/20:12
hamza21Hope this helps you :) , it is been working fine for us20:12
RandomTechrgw and keystone?20:14
RandomTechand i dont believe we have that option ivve20:14
openstackgerritJean-Philippe Evrard proposed openstack/openstack-ansible-os_keystone master: [DNM] debug why on metal fails on gates and not on my machine.  https://review.openstack.org/52495420:15
RandomTechwhats the copy_admin_key line do?20:16
hamza21rgw the cepg getway you need it for the object storage, we defined it as a new group in /opt/openstack-ansible/playbooks/inventory/env.d/keystone.yml20:16
RandomTechim not seeing that anywhere in the example?20:18
*** poul has quit IRC20:19
RandomTechit looks like you overwrote alot more than the example if im looking at it right20:19
hamza21yes, you can install rgw separately, but for us we thought it could be good to install rgw along side keystone as they need each other20:20
hamza21copy_admin_key: is variable belongs to ceph-ansible  to copy the admin key, you can refer to ceph-ansible roles for more details20:22
RandomTechi think i may pick this back up later to try again20:24
*** poul has joined #openstack-ansible20:24
RandomTech1 quick question though. which of the networks is suppposed to be the external one for floating ip's to use?20:25
*** chyka has joined #openstack-ansible20:25
hamza21in our setup we used OVS, we configured br-vlan to be the external and tenats netwotks, let me share my user_variable.yml :20:27
*** poul has quit IRC20:29
hamza21user_variables.yml, br-external is just used by haproxy:20:30
hamza21http://paste.openstack.org/show/638348/20:31
hamza21if you are using Linux bridge it will be different of course....20:31
RandomTechi am20:32
RandomTechill figure it out eventually20:32
RandomTechi have to get going20:32
RandomTechthanks everyone for trying to help20:32
hamza21no problem, good luck20:33
