4 | xiaoxi I cannot see anyone & any words,it's all blank 09:00 |
||
5 | loicd sjust: \o 09:00 |
||
6 | loicd that's what the summit is for, right ? ;-) 09:01 |
||
7 | *** rturk is now known as rturk-away 09:01 |

8 | *** rturk-away is now known as rturk 09:01 |

||
12 | sagewk anybody else want to join the hangout? 09:03 |
||
13 | nwl in future, i wonder if it's better to keep the blueprint out of the etherpad 09:04 |
||
14 | nwl so one can just see the changes/comments etc 09:04 |
||
15 | rturk the etherpad only contains the work items 09:04 |
||
16 | rturk but ya, maybe it should just be for notes? 09:04 |
||
17 | nwl rturk: yeah, so the notes can be then fed back into the blueprint, redmine etc 09:05 |
||
18 | rturk (ideas welcome -> community@ceph.com, now or anytime!) 09:05 |
||
19 | saras have you look at http://www.opencompute.org/projects/storage/ 09:05 |
||

||
21 | dmick saras: I have not; did you mean relative to the management API work specifically, or in general? 09:09 |
||
22 | nwl saras: sage is involved in the project 09:09 |
||
23 | saras thanks 09:10 |
||
24 | nwl saras: we are not doing anything very actively though (as Inktank) 09:10 |
||
25 | saras can you guy setup lower thirds 09:11 |
||
26 | saras please 09:11 |
||
27 | rturk lost your audio, loicd 09:12 |
||
28 | yehuda_hm in practice an osd should not become full, unless something is misconfigured, or the entire cluster filled up 09:12 |
||
29 | loicd damned 09:13 |
||
30 | loicd ahahah 09:13 |
||
31 | loicd I'm back 09:13 |
||
32 | saras append would be great 09:13 |

||
34 | hskinner erasure encoding is of course most valuable with geo-dispersment 09:17 |
||
35 | sagewk hskinner: true 09:17 |
||
36 | sagewk it's also not latency-sensitive in this use case... 09:17 |
||
37 | hskinner yes, ability to migrate to optimal region locality would be bonus 09:18 |
||
38 | ksp erasure encoding is also valuable in metro cluster/distance; e.g. EMC Isilon OneFS is using such algorithms 09:21 |
||
39 | saras is their paper that i can read about erasure encoding 09:22 |
||
40 | dmick saras: a bunch of resources on http://wiki.ceph.com/01Planning/02Blueprints/Dumpling/Erasure_encoding_as_a_storage_backend 09:24 |
||
41 | saras dmick: thanks 09:24 |
