| Haomeng | devananda: for this defect https://bugs.launchpad.net/ironic/+bug/1253426, I think the key is how can we checkout how many periodic_task is defined, right | 00:32 |

| * devananda goes afk for the evening | 01:28 | |
| *** nosnos has joined #openstack-ironic | 01:30 | |
| Haomeng | devananda: so this should be correct behavior, but our unittest code have to detect how periodic_task we have, and check the times which is called | 01:31 |
| devananda | AIUI, it should be called only once, regardless of # of periodic task | 01:32 |

| *** matsuhashi has quit IRC | 01:45 | |
| *** matsuhashi has joined #openstack-ironic | 01:46 | |

| Haomeng | devananda: maybe we get different call path | 01:49 |

| devananda | lucasagomes: on second thought, i'll create anotehr BP and put the all-cache-all-images one back to discussion | 19:07 |
| devananda | lucasagomes: so folks can see the history | 19:07 |
| NobodyCam | sandeepr: that may be a bit out dated | 19:08 |
| sandeepr | it is not very clear to me how can i create a image from that page, for e.g if i want use the trusty cloud image | 19:08 |
| sandeepr | what would be the steps involved? | 19:08 |
| lucasagomes | devananda, right that's better I think, so we can show the ideas we already thought of | 19:09 |
| lucasagomes | and who knows maybe we need to revive one of them | 19:10 |
| devananda | ya | 19:10 |

| devananda | lifeless: i have. this just happened to be what was in front of me when i started sketching it :) | 19:45 |
| devananda | lifeless: i can move it to etherpad | 19:46 |

| *** rongze has quit IRC | 19:50 | |

| lifeless | devananda: so we can pick a consistent hash that moves on average 1/cluster size stuff around | 19:58 |
| lifeless | devananda: but thats an average; we need to recalculate it all anyhow. | 19:59 |
| lifeless | devananda: why is deadset struckthrough? | 19:59 |
| devananda | lifeless: yea. some approaches avoid recalculating it all -- they just recalculate the affected buckets -- | 19:59 |
| devananda | but taht's a detail i'm not al ltaht concerned about | 19:59 |
| devananda | lifeless: if find_next_bucket may return a dead bucket, why pass in a dead list? | 20:00 |
| lifeless | devananda: you're write, I muddled layers | 20:02 |
| lifeless | devananda: so yes, could do affected buckets and bucket->conductor mapping. | 20:02 |
| lifeless | devananda: which would require either a bucket->instance index, or checking all instances to see which bucket they fall into | 20:03 |
| lifeless | devananda: but you wanted to avoid persisting state around this | 20:03 |
| lifeless | devananda: which is why I didn't do that | 20:04 |
| lifeless | devananda: this should be tolerably fast even on M node clusters. | 20:04 |
| devananda | lifeless: i wanted to avoid a static mapping | 20:04 |
| devananda | lifeless: we have a persistent state in teh form of the conductor heartbeat table + the results of the hash function | 20:05 |
| lifeless | not persisted to disk though | 20:05 |
| lifeless | anyhow | 20:05 |
| lifeless | If you want to tweak - go right ahead! | 20:05 |
| devananda | :) | 20:05 |
| devananda | i'll take a stab at consolidating our etherpad ramblings. thanks again! | 20:06 |
| lifeless | anytime | 20:09 |

| jbjohnso | devananda, so question on ceilometer stuff | 21:41 |
| devananda | jbjohnso: ya | 21:41 |
| jbjohnso | is the vision that in-band collection of hardware management data via agent, or out-of-band collection? | 21:41 |
| devananda | jbjohnso: periodic task in ironic-conductor calls the ironic driver interface (which needs to be created), saying "get me some hardware sensor data" | 21:42 |
| devananda | jbjohnso: driver does what ever the driver does at that point to collect it | 21:42 |
| jbjohnso | ok, and the driver is not running on the same system it is reporting on | 21:42 |
| devananda | jbjohnso: for initial implementation in the PxeAndIpmi driver, I expect that it will be via talking to the BMC of what ever node is in question | 21:43 |
| devananda | correct -- it will *never* be running on the same system it is reporting about | 21:43 |
| jbjohnso | ok | 21:43 |
| jbjohnso | so I'm going to set about my plan to try SDR caching without bothering files | 21:43 |
| devananda | it's conceivable there could be an agent running on the system that ironic is reporting about, and the ironic driver could talk to that agent | 21:43 |
| devananda | but then we're just re-inventing SNMP | 21:43 |
| devananda | jbjohnso: sounds good. but auxiliary. we also need the actual glue inside of ironic, and the particualr bits for the ipmitool // ipminative drivers | 21:44 |
| *** romcheg has joined #openstack-ironic | 21:44 | |
| jbjohnso | devananda, right, but first you need something to call upon | 21:44 |
| devananda | jbjohnso: maybe that's something you can work in parallel with linggao | 21:44 |
| jbjohnso | devananda, fyi, confluent shall present sensor data under '/node/<name>/sensors/ | 21:44 |
| devananda | jbjohnso: well, for ipminative, yes. | 21:44 |
| jbjohnso | in it's uri space | 21:45 |
| devananda | confluent? | 21:45 |
| jbjohnso | it's what I'm calling my console and hardware management thing | 21:45 |
| jbjohnso | I need to demo the api explorer and see if you think it's a good fit for the console blueprint | 21:45 |
| devananda | jbjohnso: awful close to https://www.atlassian.com/software/confluence | 21:45 |
| jbjohnso | imagine arbitrarily many shellinaboxds, but one process, one http socket | 21:46 |
| jbjohnso | and python | 21:46 |
| jbjohnso | because hey, why not | 21:46 |
| jbjohnso | so instead of managing shellinaboxd port numbers | 21:46 |
| jbjohnso | you could point to /node/n3/console/session | 21:46 |
| jbjohnso | or /node/n1/console/session | 21:46 |
| linggao | Hi devananda and jbjohnso, I saw my name mentioned. I am happy to put sensor data on the API. | 21:46 |
| jbjohnso | or /node/e84b25ce-070e-489a-b6c1-b31ce1464afd/console/session | 21:47 |
| jbjohnso | for all I care | 21:47 |
| *** rongze has joined #openstack-ironic | 21:47 | |
| jbjohnso | the point being it's a bit more... clean at accomodating many remote consoles than spawining shellinaboxd a lot | 21:48 |
| jbjohnso | but still using their very excellent javascript vt100 | 21:48 |

| NobodyCam | deva how dose one list the chassis a node is assocated with | 21:57 |

| devananda | NobodyCam: that seems like a bug | 22:00 |
| NobodyCam | :-p | 22:00 |

| romcheg | devananda: Thank you for updating the BP | 22:10 |
| devananda | romcheg: which one? I updated several today :) | 22:11 |
| romcheg | The one about RPC | 22:11 |
| romcheg | I will take a look at it tomorrow. | 22:12 |
| devananda | ah, yes | 22:12 |
| devananda | romcheg: take a look at the BP on consistent hash when you have time | 22:12 |
| devananda | romcheg: that will explain, hopefully, enough to make the RPC blueprint much simpler | 22:12 |
| devananda | we still need per-conductor RPC topic | 22:12 |
| devananda | but i think it may be somewhat low priority | 22:13 |
| devananda | i think it is only for interrupting long-running deploy, right now | 22:14 |
| romcheg | devananda: sounds interesting | 22:15 |
| romcheg | have to go now | 22:15 |
| romcheg | have a nice day | 22:15 |
