*** cdl has joined #ceph-summit2	10:42

alop	in the ATT-cloud chef repo, we use LWRP for creating keystone users/tenants glance images, etc	10:42

*** joshd has joined #ceph-summit2	10:44

alop	what's "Small to medium size"?	10:46

nwl	alop: size is less an issue that whether root ssh is something you want to run at scale	10:46

alop	k	10:47

saras	python3 or 2	10:47

dmick	2.6 atm	10:48

dmick	for the Red OSes	10:48

saras	oh	10:49

dmick	alop: no specific limitation, just sort of "where it's aimed"	10:49

Karcaw	i think it should be more than just an adoption tool..	10:49

saras	any idea how hard it is to move to python3	10:49

Karcaw	it would be better to be able to come back to it and add osd's. or be able to pull old osd's out..  or remove/add mons in the future..	10:50

dmick	saras: we're trying not to make it harder :) but it's not a target right now because of the distros	10:50

dmick	Karcaw: that should work today (except removal, which is imminent)	10:51

Karcaw	ok	10:51

saras	dmick: got you that sad are red really back on 2.6 ouch	10:52

rturk	(remember: if you want to join the hangout, ping me or scuttlemonkey!)	10:54

saras	thanks	10:55

saras	please bon't forget salt	10:56

alop	idiosyncratic is an understatement :)	10:56

kbader	are you guys streaming over the wifi?	10:58

kbader	it's supper choppy for me	10:58

rturk	I'm cabled in here	10:58

dmick	working well on the wire here kbader	10:58

kbader	yeah, my office is in a faraday cage	10:58

rturk	:P	10:59

rturk	welcome to join us in here if you want to chat	10:59

saras	virual io use case	11:00

dmick	saras: could you expand on that a bit?	11:01

kbader	there was a good talk on LWRPs at chefconf, i'll try to find the video/slide links	11:02

alram	kbader: can you paste it to pad when you find it?	11:02

saras	dmick: open compute has virual IO project that been tring get people hardware for the have buch of disk ready for ceph might be good use case	11:03

kbader	[link shortened for formatting - rdt]	11:03

*** hskinner has joined #ceph-summit2	11:03

alop	I was hoping to start deploying with chef cookbooks this week in my lab	11:03

kbader	saras: we have a contact with opencompute and have been talking about some designs with them	11:04

kbader	I'm not familiar with the virtual io stuff, do you have a link?	11:04

wonko_be	it seems to me the chef recipes are more like a one-shot replacement for a install/deploy script, that manage the cluster	11:04

wonko_be	get it up, and then never run it again	11:05

kbader	that's the way we use them (dreamhost)	11:05

kbader	deploy and manage with them	11:05

saras	kbader: http://www.opencompute.org/projects/virtual-io-2/	11:05

kbader	saras: thanks	11:05

saras	kbader: http://www.opencompute.org/ocp-summit-iv-videos/ the track 6 you good idea in frist 10 min. or so	11:06

kbader	ok, i'll check it out	11:07

kbader	wonko_be: when you say get it up and never run it again, are you refering to ceph-deploy or the chef recipes?	11:07

wonko_be	the chef recipes	11:07

wonko_be	there is nothing in there to actually manage the cluster	11:07

kbader	ah ok, well that depends on the set of cookbooks that your using	11:08

wonko_be	create pools, adding client keys, etc...	11:08

alram	wonko_be: what would you like to see in terms of management?	11:08

kbader	slightly before argonaut inktank and dreamhost cookbooks diverged	11:08

saras	so how would snyc projects work as tring to get salt up to speed	11:08

kbader	alexandre and I have done a lot of work to get them merged back together to support bobtail	11:08

saras	mailing list wiki page	11:08

wonko_be	deploying a ceph-client role to clients, allowing rbd mounts, etc...	11:08

kbader	I'm not sure if he has a copy of them on github but we should publish what we have on github	11:09

alop	wonko_be: +1	11:09

wonko_be	well, "mounts", maps is the term	11:09

kbader	wonko_be: yeah, that is needed. Checks for kernel RBD, ceph packages and drops off a key with least caps	11:09

saras	or 3, 4	11:10

wonko_be	to be honest, i'm baised, i made some cookbooks myself a year ago, and it seems like duplicate work	11:10

*** loicd has quit IRC	11:11

wonko_be	but some of the ideas can be stolen from them	11:11

kbader	alright, I'll work on getting the dreamhost cookbooks up today. Where do you have your cookbooks?	11:11

wonko_be	let me get the link, just a sec	11:12

kbader	awesome	11:12

wonko_be	https://github.com/wonko/ceph-cookbook	11:12

wonko_be	apparently, suse forked them	11:12

wonko_be	so it seems	11:12

John	Chef docs are here:	11:13

John	http://wiki.ceph.com/02Guides/Deploying_Ceph_with_Chef	11:13

wonko_be	they are nowhere complete, or up-to-date, but parts of the code might be reusable	11:13

saras	a wiki would be great too	11:13

alop	alright, thanks for setting this up	11:14

saras	John: thanks	11:14
