| kasiaGauza | Hi guys, I have a problem w/ OS Stein deployment, especially w/ the Placement service, maybe you could help | 10:46 |
|---|---|---|
| kasiaGauza | OS: Centos 7, systemctl status devstack@placement-api.service gives: active(running), but: devstack@placement-api.service[29210]: GET /placement/resource_providers (...) --- no python application found, check your startup logs for errors --- | 10:48 |

| cdent | that's...odd | 10:50 |
| cdent | kasiaGauza: if you can, can you trying running from a shell prompt: /usr/bin/placement-api and if that is not found /usr/local/bin/placement-api and see what happens? | 10:52 |
| cdent | (I'm hoping that will show a bit more of the error) | 10:54 |

| cdent | (for future reference, better to use something like http://paste.openstack.org/ for pasting) | 10:56 |
| cdent | let me see if I can make any sense of that | 10:56 |
| kasiaGauza | omg, running /usr/bin/placement == Fail, but from /usr/local/bin/placement-api == STARTING test server placement.wsgi.init_application | 10:56 |
| kasiaGauza | (cdent, i didn't know about paste, I will use it in future, thank you for showing me) | 10:58 |
| cdent | Interesting, it sounds like maybe you've somehow managed to install placement twice | 10:58 |
| cdent | and one of them is pointing to /home/sys_npfsysacc/.local which is broken | 10:58 |
| *** tetsuro has quit IRC | 10:59 | |
| cdent | I _think_ you should be able to fix this by editing the placement-api unit file that systemd is using and pointing to the right placement-api script | 10:59 |
| cdent | however, you'll want to make sure that the one that works is actually the version that you want | 10:59 |
| cdent | how did you do your install? | 10:59 |
| kasiaGauza | I will try that, the question is how to have a smooth deployment in future | 10:59 |
| cdent | agree, thus the question about how you did the install | 11:00 |
| kasiaGauza | I've cloned devstack, checked out stable/stein, added local.conf and run ./stack.sh | 11:00 |
| kasiaGauza | but, in the past I've done a few other deployments on the board, maybe they somehow messed up the OS. I know that clean.sh is unreliable | 11:02 |
| cdent | Yeah, clean.sh is not idea. Usually the best bet with devstack, if you want to be really sure, is to start with a clean VM | 11:03 |
| cdent | s/idea/ideal/ | 11:03 |
| kasiaGauza | I've created symbolic link to the correct placement-api, but the service still fails w/ the same error | 11:17 |
| kasiaGauza | execstart: /usr/bin/uwsgi --procname-prefix placement --ini /etc/placement/placement-uwsgi.ini == (...) BadZipfile: Bad magic number for central directory | 11:18 |
| cdent | kasiaGauza: is there a reference in the unit file to which python is being used, perhaps? It might be that uwsgi is looking for the wrong one and you have multiple versions installed | 11:26 |
| cdent | If that's the case, then you're likely going to have other issues beyond placement | 11:27 |
| cdent | (If I don't respond after this it is because I've been sucked into meetings) | 11:27 |
| kasiaGauza | cdent, there is no reference to the python version, but uwsgi has --python-version flag (== 2.7.5, so it's correct) | 11:39 |
| kasiaGauza | here is the log from the execution of uwsgi (...) placement-uwsgi.ini: http://paste.openstack.org/show/785680/ | 11:40 |
| *** tssurya has joined #openstack-placement | 11:53 | |
| cdent | kasiaGauza: one thing to try: $ cd /home/sys_npfsysacc/ ; mv .local .anothername | 11:58 |
| cdent | and then try again | 11:58 |
| cdent | to see if it uses a different keystonemiddlware | 11:58 |
| kasiaGauza | and... it works | 12:04 |
| kasiaGauza | but why? | 12:05 |
| *** kasiaGauza has quit IRC | 12:05 | |
| *** kasiaGauza has joined #openstack-placement | 12:08 | |
| kasiaGauza | cdent, I've got disconnected :( the placement-api seems to be working now, at first I've tried with commandline, then restarted the service | 12:08 |
| kasiaGauza | why did renaming .local folder helped? | 12:09 |
| cdent | I'm guessing that whatever is in .local is no good with the rest of your python install. There could be very many reasons why | 12:09 |
| cdent | but by renaming it, it was removed from being "seen" by python | 12:09 |
| cdent | so some other copy of the necessary libraries is not being used | 12:09 |
| cdent | s/not/now/ | 12:09 |
| kasiaGauza | I must narrow down the issue, renaming the folder broke other services, but thanks to your help cdent I am closer to solving the problem | 12:11 |
| cdent | I'm glad I was able to help a bit. Good luck. | 12:12 |
