05:13 RageLtMan whats the proper way to deploy a single controller environment? disabling HA appears to be beyond my current understanding of how fuel does things... i've gone through the configuration, task, environment yamls so far to no avail.

14:36 kozhukalov guys, please review this https://review.openstack.org/#/c/219621 it is a tiny package which is a part of version.yaml deprecation plan
14:37 kozhukalov it provides /etc/fuel_release file which contains the value of one of the fields in version.yaml

15:36 mihgen hi folks, question about plugins. Is there a way to pin kernel version to be used thru plugable framework?
15:37 aglarendil yes, you can do this
15:37 mihgen the problem which I see is that kernel is already installed when plugin deployment is triggered
15:37 aglarendil but I would punch you hard for such things in the plugin
15:37 mihgen how?
15:37 aglarendil by using apt_pinning
15:37 mihgen is it an option in the plugin?
15:38 aglarendil I do not think so - you will need to write a manifests for that
15:38 mihgen kernel installation is part of provisioning stage
15:38 aglarendil well, you can always install pinned one and reboot
15:38 mihgen yeah ok - so you can only reinstall basically
15:39 mihgen reinstall what was installed during provisioning stage. Ok, thanks aglarendil
15:39 aglarendil nope, there is a reboot task in plugin, AFAIK
15:39 aglarendil it means that you install base os
15:39 aglarendil install what you need and reboot after that

20:40 raies hi
20:41 raies I am trying to deploy 11 node HA setup using fuel 6.1
20:41 raies I am using virtual box
20:42 raies My configuration is as - 3 controller + 3 Compute + 2 Ceph OSD (Storage) + 3 Telemetry (Mongo DB)
20:43 raies During OpenStack instaltion on Controller one I am facing problem
20:43 raies Fuel Dashboard tells - Error Deployment has failed. Method granular_deploy. Deployment failed on nodes 12. Inspect Astute logs for the details
20:44 raies And when I dive in Controller logs then I can see following error in Neutron server logs
20:44 raies Exception during message handling: (OperationalError) (2003, "Can't connect to MySQL server on '192.168.0.1' (111)") None None

21:18 adanin mihgen: As aglarendil said you install a new kernel, change grub and reboot using reboot task.
21:22 julien_ZTE joined #fuel-dev
21:23 mihgen raies: did you try to run network verification?
21:24 mihgen it can easily be an issue. Also, how much memory do you have for nodes.. ?
21:25 raies mihgen: hi
21:25 mihgen adanin: thanks. do we have any other example plugin which is doing it already/
21:25 raies mihgen: Yes I had done nw verification
21:25 raies again I have 1GB for all controller nodes
21:26 raies and 2GB for 1 compute and 1GB for all remaining
21:26 raies mihgen: So probably it is memory issue ?
21:26 mihgen 1gb is not enough for controllers...
21:27 mihgen you whether need to run it on hardware where you can create 2-3 gb vms
21:27 mihgen or just limit number of nodes on your laptop/desktop, but allocate more memory to lower amount of VMs
21:27 raies okk btw I am again trying to run it. This time I will configure 7 nodes instead of 11 with increased memory bank
21:27 adanin mihgen: Mellanox is using a reboot task to change a kernel cmdline.
21:28 raies mihgen: thanks
21:28 mihgen adanin: ok. do they have an open sourced plugin for it?
21:29 adanin Mellanox plugin is under Apache licence.
21:29 mihgen raies: sure. ensure to run network verification before deployment. If you see an issue again, then we'd need to troubleshoot and see why mysql is not running / no connection over management network, etc.
21:29 adanin mihgen: Here their code https://github.com/stackforge/fuel-plugin-mellanox/blob/master/tasks.yaml#L57-L62
21:31 mihgen thanks adanin!
21:31 raies mihgen: yes I will do it. Thanks
21:37 adanin aglarendil, nurla, angdraug: RageLtMan said that Fuel 7.0 has a problem with a single controller installation. After multiple graceful reboots of the controller Galera fails to replicate with peers because there aren’t any. Unfortunately he cannot provide a diagnostic snapshot but I think we should try to reporduce this ourself.

23:55 RageLtMan follow-up to adanin's comment: i've now induced several less-than-graceful reboots (the controller is a kvm domain since it doubles as the storage node and resides atop a few zpools), and it's coming back each time. Murphy's law of diagnostics applies here. I'll do a snapshot, and gather whatever you folks need if i can reproduce it before i stabilize the hadware beneath the domain
23:56 RageLtMan That said, there is some sort of unpleasant gremlin or imp lurking in the galera configuration which makes a single master node occasionally come back looking for non-existent peers and refusing to run MySQL
