| 21:56:35 | dansmith | well, do we know if it's deleted or just not being shown in the API? | |

| 21:56:45 | andrewbogott | good point, it could be either | |

| 21:57:16 | andrewbogott | dansmith: does that minimum_version_check happen via RPC? I stuck a bunch of debug lines in the version check on my compute node and they were never traversed. | |

| 21:57:44 | dansmith | computes can't talk to the database, so yes | |

| 21:58:45 | andrewbogott | I don't think I've ever seen @base.remotable_classmethod but I take that to mean 'this happens on a totally different system' | |

| 21:59:11 | andrewbogott | ok | |
| 21:59:11 | andrewbogott | ok | |
| 21:59:18 | andrewbogott | that solves another mystery then | |
| 21:59:18 | clarkb | gmann: ya and it works like 90% of the time | |

| 21:59:19 | dansmith | and yes, you might be right.. you might need to restart conductor which does that on behalf of the compute | |

| 21:59:38 | clarkb | gmann: that is why I suspect maybe it has to do with the cache refresh since in theory that only happens if you exceed timeouts or similar | |

| 21:59:45 | dansmith | yeah, I hadn't really thought of that, but I guess we'd get conductor's in-memory "cache" of that version | |

| 22:00:12 | andrewbogott | That seems like the simplest explanation. Not easy to fix though | |

| 22:00:20 | andrewbogott | other than having the 'delete' command print | |

| 22:00:26 | andrewbogott | "ok now restart your conductor" | |

| 22:00:27 | dansmith | not sure that needs a fix | |

| 22:00:56 | andrewbogott | d'you think the conductor would've refreshed its state eventually? | |

| 22:01:17 | clarkb | gmann: fungi mentioned it could possibly be an openstack(client|sdk) regression where it isn't passing that info properly | |
| 22:01:17 | dansmith | no, all the nodes will hold that value in memory until restart, that's kinda the point | |

| 22:01:28 | dansmith | API and scheduler will do the same | |

| 22:01:46 | dansmith | it's just that restarting an api worker will resolve it, whereas computes are dependent on the conductors for it | |

| 22:03:21 | andrewbogott | It's really the conductor's job to provide /current/ database state though isn't it? | |

| 22:03:40 | andrewbogott | Are there reasons why we would want the conductor to not re-read for every query? (Other than performance) | |
| 22:03:40 | andrewbogott | Are there reasons why we would want the conductor to not re-read for every query? (Other than performance) | |
| 22:04:16 | dansmith | yeah, it's expensive, and it also controls conductor's RPC pin, which we don't want to shift at runtime unless you restart or HUP it | |

| 22:05:43 | dansmith | the conductor also translates things according to the version pin and the versions supported by the compute that is asking for a thing | |

| 22:06:00 | andrewbogott | hmmmm | |
| 22:06:00 | andrewbogott | hmmmm | |
| 22:06:49 | andrewbogott | So really it should be pushed -- when a service is deleted it should force some kind of reload (rather than the conductor re-reading the db periodically) | |

| 22:06:59 | andrewbogott | that sounds like a pain to implement for a tiny gain | |

| 22:07:44 | dansmith | you want to fan-out to every service in the cluster every time a service is deleted just in case some of them need to re-calculate the min version? | |
