| 13:42:45 | mriedem | avolkov: btw thanks for the sqla make_url tip | |
| 13:43:32 | Kevin_Zheng | mriedem: yeah, I will update tomorrow, btw, I left one remaining comment about deleting tags, could you have a look? | |
| 13:43:34 | ildikov | stvnoyes1: on my list, thanks for the heads up | |
| 13:43:58 | mriedem | Kevin_Zheng: this? https://review.openstack.org/#/c/459593/10/nova/conductor/manager.py@1086 | |
| 13:44:28 | Kevin_Zheng | Ah yes | |
| 13:44:34 | mriedem | :) | |

| 13:45:52 | Kevin_Zheng | mriedem: thanks, we are flying to Suzhou tomorrow and I will update it tomorrow evening or the day after that | |
| 13:47:19 | bauzas | edleafe: just in case you don't know, I'm working on updating my series | |
| 13:47:40 | bauzas | edleafe: please stop updating your ones, given I'd prefer you reviewing mine | |
| 13:50:20 | avolkov | mriedem: you're welcome | |
| 13:51:21 | mriedem | Kevin_Zheng: thanks | |
| 13:57:30 | edleafe | bauzas: I saw your notes | |
| 13:58:04 | bauzas | ack | |
| 14:02:49 | edleafe | Scheduler subteam meeting going on now in #openstack-meeting-alt | |
| 14:13:55 | openstack | Launchpad bug 1690819 in OpenStack Compute (nova) "nova-manage [..] api_db sync on F25 results in RuntimeError: no suitable implementation for this system" [Undecided,New] | |
| 14:13:55 | lyarwood | slaweq_: https://bugs.launchpad.net/nova/+bug/1690819 FYI, I'm also seeing that in F25 | |
| 14:23:11 | sdague | lyarwood: that's a blow up deep in monotonic | |
| 14:23:41 | sdague | lyarwood: I wonder why it's blowing up there | |
| 14:25:28 | lyarwood | sdague: yeah this is odd, stepping through this in a venv now and getting the following trace http://paste.openstack.org/show/609576/ | |
| 14:27:01 | openstackgerrit | Mathieu Gagné proposed openstack/nova master: Add ability to signal and perform online volume size change https://review.openstack.org/454322 | |
| 14:27:20 | artom | So, I tried find_library('foo') and it just returns False, without blowing up... | |
| 14:30:37 | bauzas | oh man | |
| 14:31:23 | bauzas | I was about to write a reservoir sampling method for getting a random subset of a long iterator | |
| 14:31:52 | bauzas | until I just discovered that we put all the hosts in memory after weighing those ! | |
| 14:32:04 | bauzas | so, weighed_hosts is a full list | |
| 14:32:19 | bauzas | I thought we were smarter | |
| 14:33:49 | bauzas | like getting weights for each of the items of an iterator and just sorting them by indexes instead of putting all in memory | |
| 14:33:55 | bauzas | fairly inefficient | |
| 14:36:01 | stvnoyes1 | nova core: review 'add Cinder v3 detach to shutdown_instance' - https://review.openstack.org/#/c/463987/ - it has a +2, but it needs a workflow +1. thanks. | |
| 14:36:10 | bauzas | oh man, even the filtering creates a list... | |
| 14:36:48 | bauzas | so, we're gentle with operators by using iterators when getting a full list from DB, but then we put that all in memory once we loop over filters | |
| 14:36:58 | bauzas | and then we do that again with weighers | |
| 14:37:12 | bauzas | so we basically duplicate the size in memory | |
| 14:38:14 | bauzas | ^ that could be a problem with large deployments | |
| 14:39:22 | lyarwood | sdague / artom ; I think it's https://github.com/eventlet/eventlet/issues/401 , I can't reproduce with eventlet 0.20.1 | |
| 14:41:19 | sean-k-mooney | sfinucan: hi o/, back from boston? | |
| 14:41:58 | sdague | lyarwood: yeh, that seems likely, I wonder why you are hitting it consistently but it's not showing up other places | |
| 14:46:34 | lyarwood | sdague: no idea, we have eventlet==0.21.0 in the gate at the moment | |
| 14:47:12 | sdague | lyarwood: I guess it's a race, I wonder if your env is on the slower or faster side of things | |
| 14:47:20 | sdague | just to figure out when things expose | |
| 14:49:07 | lyarwood | sdague: hopefully on the faster side vs the gate given it's the only heavy workload on my current pretty beefy host | |
| 14:50:36 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Make discover_hosts only query for unmapped ComputeNode records https://review.openstack.org/427903 | |
| 14:58:37 | mriedem | jaypipes: https://review.openstack.org/#/c/427903/ is the last piece in the 'make auto-discover_hosts faster' series | |
| 14:59:01 | jaypipes | mriedem: k, will review. currently on a plane out to China... | |
| 14:59:08 | jaypipes | mriedem: spotty internet.. | |
| 14:59:10 | mriedem | oh fun | |
| 15:01:14 | alex_xu | jaypipes: $20 for more than 10 hours flight, it is totally worth :) | |
| 15:03:13 | openstackgerrit | Monty Taylor proposed openstack/nova master: WIP Add description of server addresses objects https://review.openstack.org/464331 | |
| 15:05:07 | jaypipes | mriedem: done. | |
| 15:05:23 | mriedem | thanks | |
| 15:05:34 | jaypipes | alex_xu: still on way to LAX first, then the biggie. :) | |
| 15:06:59 | jaypipes | mriedem, sdague, anyone: seen this? from monotonic import monotonic as now # noqa | |
| 15:07:00 | jaypipes | raise RuntimeError('no suitable implementation for this system') | |
| 15:07:00 | jaypipes | File "/home/jaypipes/src/git.openstack.org/openstack/nova/.tox/functional/local/lib/python2.7/site-packages/monotonic.py", line 169, in <module> | |
| 15:07:00 | jaypipes | ||
| 15:07:00 | jaypipes | RuntimeError: no suitable implementation for this system | |
| 15:07:26 | jaypipes | just installed a fresh venv for tox/functional... | |
| 15:07:38 | mriedem | i have no | |
| 15:07:40 | mriedem | *not | |
| 15:07:51 | artom | jaypipes, there's been some chatter about it, yeah | |
| 15:07:57 | artom | jaypipes, see lyarwood's link above | |
| 15:08:10 | artom | https://github.com/eventlet/eventlet/issues/401 | |
| 15:09:25 | openstack | Launchpad bug 1690819 in OpenStack Compute (nova) "nova-manage [..] api_db sync on F25 results in RuntimeError: no suitable implementation for this system" [Undecided,New] | |
| 15:09:25 | lyarwood | & https://bugs.launchpad.net/nova/+bug/1690819 | |
| 15:09:45 | lyarwood | jaypipes: going back to eventlet 0.20.1 works around the issue for now btw | |
| 15:09:51 | lyarwood | for me at least | |
| 15:11:19 | sdague | that looks like it landed today | |
| 15:11:47 | jaypipes | lyarwood, artom: thx much for the help! | |
| 15:12:01 | jaypipes | yet another buggy eventlet release... | |
| 15:12:19 | artom | Well, if you monkey-patch all evarything... | |
| 15:12:46 | jaypipes | indeed. | |
| 15:13:48 | sdague | I proposed a revert on it - https://review.openstack.org/#/c/464664/ | |
| 15:17:09 | jaypipes | sdague: cool, cheers | |
| 15:27:17 | artom | mriedem, mind checking out https://review.openstack.org/#/c/415520/33 again? There's a link down there to the passing Tempest test. Thanks :) | |
| 15:27:27 | mriedem | yeah | |
| 15:27:50 | cfriesen | has anyone looked at the "fairness" behaviour of the oslo_concurrency.Lock() and Semaphore() and RWLock()? We're seeing some indications that if one eventlet drops the lock and immediately reaquires it then it can "starve" other eventlets waiting on the same lock. | |
| 15:29:17 | mriedem | dansmith: see alex_xu's question here https://review.openstack.org/#/c/461532/4/nova/compute/api.py - was there a reason we didn't do a 409 on HostAPI.compute_node_get when there are duplicates? apparently i pointed that out in the original review but never published my comments until just now. | |
| 15:31:07 | dansmith | mriedem: will looks when I'm off this cal | |

| 15:46:04 | ralonsoh | Hi, I have bug related to SR-IOV. When a PF is attached again to the OS (detached from the VM), the VF config (sriov_numvfs) is unset | |
| 15:46:09 | openstack | Launchpad bug 1679703 in OpenStack Compute (nova) "Unable to boot instance with VF( direct-port ) because the PF is not online" [Undecided,New] - Assigned to Rodolfo Alonso (rodolfo-alonso-hernandez) | |
| 15:46:09 | ralonsoh | #link https://bugs.launchpad.net/nova/+bug/1679703 | |
| 15:46:30 | ralonsoh | I propose two ideas in the bug. Do you have any feedback? | |
| 15:47:02 | ralonsoh | IMO, the second one is cheaper and easier | |
