| iwonka | hi everyone! i have some trouble with devenv - when I try to create a cluster it says "Error occurred during cluster creation:" and it shows the table with cluster information, where status is error. I'm followitg this guide: https://docs.openstack.org/developer/sahara/devref/quickstart.html | 20:03 |
| iwonka | does anyone know what the problem may be or where to look for the solution? | 20:03 |
| *** esikachev has joined #openstack-sahara | 20:12 | |
| *** jamielennox is now known as jamielennox|away | 20:13 | |
| *** esikachev has quit IRC | 20:18 | |
| *** jamielennox|away is now known as jamielennox | 20:20 | |
| tosky | iwonka: it depends on the error, really; check the logs of sahara (possibly in debug mode) and the heat logs | 20:26 |
| tosky | most of the time, it's a matter of not enough resources for the cluster | 20:26 |
| tosky | (like at least 8GB for Cloudera mater, ofr example) | 20:26 |
| iwonka | tosky: i don't have /var/log/sahara.log file (if this is where i should check) but i have debug=true and use_stderr=true in sahara.conf | 20:30 |
| tosky | iwonka: no /var/log/sahara/ directory, with log files for the api and engine services? | 20:31 |
| iwonka | no, that's all i have there: http://paste.openstack.org/show/607769/ | 20:33 |
| iwonka | actually, one really silly question: i should place the conf file in /etc/sahara/sahara.conf or /opt/stack/sahara/etc/shara/sahara.conf? | 20:35 |
| *** tnovacik has joined #openstack-sahara | 20:36 | |
| tosky | that depends probably on the prefix where you installed | 20:36 |
| tosky | (I usually install from packages) | 20:36 |
| tosky | there are no logs for the other services in /var/log | 20:37 |
| tosky | so maybe it's all somewhere else | 20:37 |
| iwonka | i intalled to /opt/stack, there's source code and all the stuff | 20:37 |
| iwonka | *installed | 20:37 |
| tosky | so check the configuration files and the logs in the /opt/stack tree | 20:38 |
| iwonka | i did find . -name "sahara.log" in /opt/stack and it gave nothing | 20:40 |
| tosky | it's not sahara.log | 20:50 |
| tosky | it's a sahara directory, with sahara-api.log and sahara-engine.log | 20:50 |
| tosky | but check the configuration file, it should say something about the position of the log file | 20:51 |
| tosky | and it should be the same for the other openstack services (nova, neutron, etc) | 20:51 |
| iwonka | okay, found the file, thanks :) | 20:54 |
| iwonka | but what should I look for? I mean, I've read all the messages containing my problematic cluster id, there are almost only DEBUG messages and one INFO about status being changed to validating | 21:01 |
| iwonka | and DEBUG messages are like curl and some responses | 21:02 |
| iwonka | and one start from server | 21:02 |
| tosky | check the engine log, and see where the process stops | 21:02 |
| tosky | sahara-engine passes the execution to heat | 21:02 |
| tosky | heat tries first to create the servers | 21:02 |
| tosky | (so you should see something in nova logs too) | 21:02 |
| iwonka | oh, there's a lot of errors in eng log | 21:03 |
| iwonka | if i'm right the important part is Error during operating on cluster (reason: publicURL endpoint for orchestration service not found) | 21:04 |
| tosky | did you deploy heat? | 21:05 |
| iwonka | ummm, i don't think so | 21:05 |
| iwonka | i just followed the guide | 21:05 |
| *** esikachev has joined #openstack-sahara | 21:06 | |
| tosky | you need heat, please make sure to deploy it | 21:08 |
| iwonka | tosky: so I should do something like https://docs.openstack.org/developer/heat/getting_started/on_devstack.html ? | 21:08 |
| tosky | if you use devstack. add heat to the configuration and restack again | 21:08 |
| iwonka | yeah, i do | 21:08 |

| iwonka | hmmm, after enabling heat cluster hangs in "Waiting" state | 22:31 |
| iwonka | log says "Can't login to node, IP: 10.0.0.8, reason error: [Errno 110] Connection timed out" | 22:31 |
| iwonka | tosky? or anyone elsewho knows what happenes there? | 22:31 |
| tosky | iwonka: how did you define the the node group template? Did you assign a floating IP network (aka an external network where you can get floating IPs)? | 22:34 |
| tosky | Can you create an instance (directly with nova, not with sahara) and assign a floating IP on that external network and access the instance through that IP? | 22:34 |
| tosky | this is all unrelated to Sahara strictly, so far | 22:35 |
| iwonka | tosky: openstack dataprocessing node group template create --name vanilla-default-worker --plugin vanilla --plugin-version 2.7.1 --processes datanode nodemanager --flavor 2 --auto-security-group | 22:37 |
| tosky | iwonka: the floating IP | 22:37 |
| tosky | you need one to access, or you need to configure the system so that the controller can access the instances through the private network | 22:38 |
| iwonka | and I don't use floating ip, I have use_floating_ips=false in sahara.conf | 22:38 |
| iwonka | is that bad? | 22:39 |
| tosky | so what network is 10.0.0.8? The private network? | 22:39 |
| iwonka | i don't know, but probably, I have --neutron-network private in cluster creation operation | 22:39 |
| tosky | https://docs.openstack.org/developer/sahara/userdoc/configuration.guide.html here says something | 22:39 |
| iwonka | it says it can use fixed ips | 22:40 |
| iwonka | but i should configure something more? | 22:41 |
| iwonka | sorry for silly questions, I don't understand what's going on | 22:41 |
| *** esikachev has joined #openstack-sahara | 22:42 | |
| tosky | you need to ensure that the controller (where sahara runs) can connect to instances with an IP on the private network | 22:43 |
| iwonka | can i just run it with --neuton-network public? or is it not that simple? | 22:43 |
| tosky | do you have a public network with floating IPs? You said that you don't have it | 22:45 |
| iwonka | i think i don't. i didn't create any network at all | 22:47 |
| *** esikachev has quit IRC | 22:47 | |
| tosky | well, that's something that you can check | 22:47 |
| tosky | checking the network defined | 22:47 |
| iwonka | openstack network list shows a public network | 22:48 |
| iwonka | and a private one | 22:48 |
| tosky | so you do have a public network | 22:49 |
| tosky | then please enable floating IPs | 22:49 |
| tosky | I guess than the public and private network are connected by a router? | 22:49 |
| iwonka | do i have to restack after enabling floating ips? | 22:50 |
| tosky | isn't it a local settings in sahara.conf? | 22:50 |
| iwonka | it is | 22:51 |
| tosky | so you need to restart only the sahara services | 22:51 |
| iwonka | how to restart only them? i usually did ./unstack.sh and ./stack.sh | 22:51 |
| tosky | devstack, if you configure it, creates a screen session where you can check every service | 22:52 |
| tosky | I don't remember anymore if this is configured by default | 22:52 |
| tosky | if you attach that screen session you can reach the windows inside for sahara-api and sahara-engine and restart them | 22:52 |
| tosky | or of course you can go for the nuclear option and unstack/stack | 22:53 |
| tosky | I'd suggest a bit of devstack documentation :) | 22:53 |
| iwonka | ok, i'll read about it. it's just i don't know what i don't know, so i'm not sure what to read about… | 22:56 |
| iwonka | anyway, thanks for your time | 22:56 |
| tosky | https://docs.openstack.org/developer/devstack/development.html | 22:57 |
| iwonka | tkanks! | 23:00 |
