broskyHi there13:55
*** nikparasyr has quit IRC13:55
broskyI've sucessfully deployed openstack on a 4 compute nodes and 3 infrastructure VM's, cinder nfs13:56
broskyI have another cluster, identical hardware but installed manually  - everything works. (it's just that now I try it via ansible)13:56
brosky and i'm having dificulties understanding ansible ceph playbooks13:56
broskyanyone here care to spare a few minutes ? :)13:56

noonedeadpunkbrosky: hey, actually we do use ceph-ansible for ceph deployments, so no big experts in their structure tbh:)14:41
noonedeadpunkI mean that OSA just leverages ceph-ansible14:41
broskyI know14:43
*** pcaruana has quit IRC14:44
broskyI've installed previously ceph via ceph-deploy and everything was ok14:44
*** pcaruana has joined #openstack-ansible14:45
broskybut know i'm in the dark with ansible14:45
broskyso basically I have to study ceph-ansible and try to implement/configure that in openstack-ceph14:46
broskyIMO the production examples seem very incomplete.14:46
*** schwicht has joined #openstack-ansible14:51
mgariepybrosky, with ceph-ansible there is a takeover playbook14:56
mgariepywhat i would suggest is deploy a small cluster un openstack over a couple of vms with your old deploy, and try to do the takeover.14:56
broskyhmmm.. i'm checking this now.14:58
broskybasically I don't need the existing cluster14:58
broskythe ideea is to replace the existing cluster with a new one14:59
broskyexisting cluster 4 x (52 cores, 256G, 6x4TB); replaced with 4 x (72 cores, 512G, 6x10TB)14:59
broskyexisting cluster was installed by me by hand, following the official docs,15:00
broskythis new one I want to do it via ansible15:00
broskythis new one I want to do it via ansible :)15:00
broskyand that's why I found some things obscure - mostly due to my lack of experience with ansible15:00
noonedeadpunkbrosky: ok, and you want to use another ceph or just connect the new one to old ceph?15:01
broskyNo, I don't want them interconnected. I just one to be deployed via openstack-ansible15:01
broskyso far the playbook setup-infrastructure.yml hangs at discovering the OSD's15:02
broskyand i've discovered now that ansible will use any disks without partitions15:02
noonedeadpunkhave you looked through https://docs.openstack.org/openstack-ansible/latest/user/ceph/full-deploy.html ?15:02
broskyYes. My particular setup is that the OSD-s are on the same metal where the compute is15:03
broskyI think they call it HCI15:04
broskyand there shoiuld be a paramenter somewhere "is_hci = true"15:04
noonedeadpunkyeah, I see15:04
noonedeadpunkyep, this is ceph-ansible variable15:05
noonedeadpunkI think you can re-run ceph-install.yml isntead of the whole setup-infratructure once you're at ceph setup step15:06
noonedeadpunkbut not sure I got what exactly the issue is15:07
broskysetup-hosts.yml has no failures and setup-infrastructure hungs at one point (I think it's discovering the OSD's)15:08
broskyI''m running now again the playbook, i'll get back with details.15:08
broskyTASK [ceph-osd : wait for all osd to be up] *********************************************************************************15:08
broskyFAILED - RETRYING: wait for all osd to be up (60 retries left).15:08
broskywell, here we go15:08
mgariepydo you mind binpaste your yml config ?15:10
noonedeadpunkand eventually what does ceph -s and ceph osd tree report?15:10

broskyok ok - pastebin from now on :)15:14
mgariepyyour openstack ansible config ?15:14
mgariepyprobably just the part about ceph osds15:14
broskyI haven't changed there anything because in openstack_user_config.yml and in user_variables.yml there's no mention of osd's15:15
broskythats' why i'm saying that i'm a bit confused15:15
mgariepyok. you deploy via openstakc-ansible ?15:16
broskyyes15:16
broskyI have a working openstack with nfs backend and I want to add ceph - osd's on compute nodes15:16
broskyso basically i've configured ceph-osd_hosts to have the same IP addresses as hte compute hosts15:17
broskythen ceph-mon_hosts, ceph-mds_hosts and ceph-nfs_hosts on the infra1,2,3 machines15:18

*** thuydang has joined #openstack-ansible15:19
broskyhttps://pastebin.com/WzQLw97P - the user_variables.yml part15:19
broskyall standard - i haven't changed anything15:20
noonedeadpunkbrosky: have you defined ceph-osd group?15:33
noonedeadpunkdisregard15:33
noonedeadpunksaw answer to my question15:33
noonedeadpunkyeah eventually it's more ceph-ansible thing which I'm not so big expert at...15:35
noonedeadpunkbrosky: I think you can/should define devices variable at host_vars which would be used as osds https://github.com/ceph/ceph-ansible/blob/master/roles/ceph-osd/defaults/main.yml#L24-L3215:36
