mtaninoanish: hi,00:12
mtaninoanish: you try to fix file read problem?00:13
anishmtanino: not exactly. I'm just changing allowed errors from any open exception to file not found00:13
anishsince the idea behind that changeset when it first came in was to reuse pre-existing chap information00:13
anishactually, I should just rebase it on top of your changeset00:14
mtaninoanish: may be I think so, but00:15
gugl2jgriffith, please take a look at the comments hemna put it there
mtaninoanish: if your patch will land before mine, I will rebase mine :)00:15
mtaninoanish: I already rebased my patch 3 or 4 times...00:16
jgriffithgugl2: thanks00:16
jgriffithgugl2: hemna so fair00:16
jgriffithgugl2: hemna just FYI what I'm trying to avoid is the "one vendor features" that we keep doing lately00:16
anishmtanino: I HIGHLY doubt mine will land before yours, but I will rebase as well in case yours land first as well00:17
anish*one too many 'as well's00:17
hemnayup, we don't want single vendor features either.00:17
jgriffithhemna: I know you don't00:17

bitbltif i only have one nfs mount point, and i decide i want to change it to something else, eg a re-IP, is it right that I'll have to manually change the provider_location in the db, then update the domain xml file to the new location too?00:18
gugl2jgriffith, can you remove your vote after read the comments00:18
*** sgotliv__ has quit IRC00:18
mtaninoanish: I set star mark of your patch, so I will get every change :)00:19
jgriffithhemna: gugl2 and note that I'm aware that's not the sched change itself, I commented that since I didn't review that patch before it merged I was raising my concern in the patch that was avail00:19
anishmtanino: a+00:19
*** Mandell has quit IRC00:21
gugl2jgriffith, sched patch has been approved and merged by the might need to let it go :)00:22
jgriffithgugl2: I'm aware, and yes you're right.  I think I just need to let it go for a lot of things at this point00:22
jgriffithgugl2: but I won't :)00:23
hemnawe have docs patches up in process already00:23
gugl2jgriffith, sigh00:23
jgriffithhemna: gugl2 ok, there ya go.00:24
jgriffithhemna: gugl2 thanks00:24
hemnathanks man00:25
jgriffithhemna: NP, sorry I'm such a pita00:25
thingeejgriffith: with regards to your question about documentation for the evaluator here
gugl2jgriffith, thanks John!00:26
thingeejgriffith: documentation is posted
hemnawell I wouldn't say that.   having docs in place is critical for everyone, and I think that was a good issue to raise00:26
jgriffiththingee: yes, I got that00:26
jgriffiththingee: but please note, that wasn't what i was looking for00:26
jgriffiththingee: I was looking for some information on the actual classes that were added00:26
jgriffiththe implementation itself00:27
jgriffiththingee: particularly the evaluator code00:27
*** bitblt has quit IRC00:27
jgriffiththingee: but perhaps I'm out of line here00:27

*** tbarron has joined #openstack-cinder00:29

*** enterprisedc_ is now known as enterprisedc00:30
jgriffiththingee: yeah, that's all I was looking for really00:31
*** jcru has joined #openstack-cinder00:31
leeanthojgriffith, I can add more details on the evaluator part of the driver filter  in the openstack-manuals if you want00:31
jgriffithand given it only had 3 reviewers it doesn't seem like I'm completely out of line00:32
jgriffithleeantho: so honestly if I'm the only one worried about it don't waste your time00:32
jgriffithleeantho: I was having some difficulty parsing through how your code works with the evaluator classes is all00:32
jgriffithleeantho: but I'll spend a few minutes looking at it later and I'm sure it will be just fine00:33
thingeejgriffith: Well I think it's fair. So leeantho I think the expectation of this from the docs "You should consult the best practices for the drivers that you plan on doing this to for more information" is not great.00:33
*** lcurtis has quit IRC00:34
jgriffithleeantho: for the record, when I see scheduler changes without a descent number of reviewers I get nervous.  I also consider winston-d a lead on scheduler and prefer to see his reviews on things that go in if they're significant00:34
thingeejgriffith: not sure why winston-d wasn't added originally =/00:35
thingeebut I agree, we usually have winston-d sign off on these things.00:35
*** Mandell has joined #openstack-cinder00:35
jgriffithwell, I'm going to take gugl2 's advice and "let it go", starting with making the drive home.  BBL00:36
hemnadrive safe00:36
*** Mandell has quit IRC00:36
*** Mandell has joined #openstack-cinder00:36
gugl2jgriffith, it will be good for your health. bye00:37
leeanthothingee, yes the line about consult the drivers best practice for the capabilities property is because the sub-properties in that are defined by the driver (based on how the scheduler does it right now),  not sure how to document that in a general way since it could be different for each driver :(00:37
thingeeleeantho: so where I'm getting it at, is you're setting this unknown expectation. Consulting the vendor on using a feature in OpenStack? That already makes setting up this feature difficult.00:38
xyangthingee, jgriffith, hemna: can I ask you to review these: Modify CG  Incremental backup
thingeexyang: since you +2/A can you explain this to me?00:39
xyangthingee: which one?00:40
thingeesee backlog in the room and with regards to this change
xyangthingee: this allows the driver to have custom filter and weigher functions00:41
thingeeare there any other vendors looking to use this?00:46
xyangthingee: we would like to use this.  in the L planning00:46
thingeeoh excellent. can I get some examples of how you would use this compared to what you don't get in the filter scheduler?00:47
xyangthingee: we are still looking at what is the best formula for us.  I can definitely give an update at a later point00:48
*** chenleji has joined #openstack-cinder00:48
thingeexyang: I guess that's the problem I'm having is understanding how other vendors plan to use this.00:49
*** r-daneel has quit IRC00:49
thingeexyang: I know it'll work for HP00:49
thingeeand the problem is understanding this before L00:49
xyangthingee: so it allows you to use not only capacity, but other performance measurements to filter and weigh00:49
thingeeI don't have to know specifics, but just want to understand that the framework works well for others and just some general ideas of how it can be used.00:49
thingeexyang: ah that would be kind of interesting00:50
thingeehemna, leeantho, kmartin: what sort of usecases were you all seeing with this for your drivers?00:50
*** scottda_ has joined #openstack-cinder00:50
*** ebalduf has quit IRC00:51
*** Mandell has quit IRC00:51
hemnathingee, so this entire idea came from a discussion in Hong Kong00:51
thingeehemna: apologies for my fuzzy mind :)00:52
*** markvoelker has joined #openstack-cinder00:52
hemnaDuncan and I argued with the guy from Redhat about this00:52
thingeehaha I remember that00:52
hemnaand came up with the model of the goodness functions00:52
xyangthis blueprint was originally registered by winston-d00:52
hemnait was almost a match to the death, then we all figured it out00:52
xyangI believe winston-d reviewed the spec as well00:53
thingeeI think it would've been really good to have winston-d sign off on this one.00:53
thingeebefore merge00:53
thingeeyeah he approved the spec. But xyang as you know, specs change. :)00:53
xyangthingee: very true:)00:54
hemnathingee, to be fair, the spec had been up since October00:54
leeanthothingee,  winston-d, did look over it some and gave some feedback on it  but never left comments on the patch itself00:55
thingeehemna: that's not what were talking about here. I'm trying to understand the point jgriffith raised of..OK, we have this thing. Lets hear how people plan to use this. This would've been a better discussion during spec talk actaully00:55
thingeeleeantho: yeah, my point is code most of the time ends up being different, or not meaning to be different from the patch00:55
*** markvoelker has quit IRC00:56
*** markvoelker_ has joined #openstack-cinder00:56
thingeeunderstand my nervous position here. I want to know that this works for others.00:56
hemnaso the idea of this is to allow drivers to provide a goodness value that is a number between 0-100.  that number is compared against other answers from other drivers to help the scheduler decide if a provisioning request should land on it or not.00:56
leeanthoI meant he looked at the patch some,  he gave me some feedback when it was different than he imagined (i had combined the filter and weigher together)00:56
hemnaand the mechanism allows admins that understand the backends to tweak the algorithm for generating that goodness number.00:57
hemnaas an admin might not want to have more than X volumes created on a backend00:57
hemnaor whatever00:57
thingeeleeantho: if he's talking to you on the side and not in the patch, that's not good for me. I need feedback in the patch.00:57
hemnathingee, +100:57
hemnaok so winston-d should have commented on the spec00:57
hemnahe didn't00:58
hemnawe can't control that00:58
thingeehe did comment on the spec00:58
thingeeeven approved it00:58
tbarronso is merged but the link to the blueprint spec in its commit message fails00:58
hemnaoh crap I'm looking at the wrong review :P00:58
thingeeI'm saying I would feel better having feedback from him on this patch before end of K00:58
* hemna is confused00:59
tbarronjust trying to understand impact myself00:59
*** Lee1092 has joined #openstack-cinder00:59
hemnatbarron, yah I've been seeing that behavior with other reviews as well01:00
hemnathe BP vanishes after it's landed01:00
hemnano idea01:00
leeanthothingee, I agree it would have been better to have the feedback on the patch itself.  It had been a message that came up in openstack-cinder when kmartin and winston-d were talking about the spec/patch01:00
thingeeI want feedback from winston-d on this patch before end of k and make sure it's what we envisioned from the spec.01:01
hemnayah so the cinder review was up since October w/o comment from winston01:01
tbarronhemna: kk, but how do you backtrack to the spec?  guess the search prob isn't that hard, but one would think the commit msg would take one there01:01
tbarronthingee: thx01:02
thingeeso a couple of things to be clear on this: winston-d should comment on this review (you can still publish comments in gerrit after merge). I also really want to hear from some other vendors on how they plan to use this, not just HP. If we can't have this information before K, we won't have it for K. I think this is fair information to understand.01:03
*** Mandell has joined #openstack-cinder01:03
thingeeI do agree this is late request after spec approval, but if it's causing this much of a worry, then I don't understand why we can't know this information up front.01:04
thingeeI don't need detailed information from other vendors either. Just want to make sure this framework will REALLY work for others.01:04
hemnathingee, I thought that was what the review process was for ?01:04
hemnait was in review for 5 months01:04
hemnaand noone cared01:04
hemnawell some folks did01:04
thingeethat's what we said about replication01:04
thingeelets not repeat this01:05
hemnaall I'm saying is, that we had this up for 5 months in review, and those conversations should have happened during the review01:05
thingeeunderstood. But if there's not interest, then maybe it's not interesting for other vendors in openstack01:05
thingeeso why it in this common interface?01:06
hemnajust because others don't have plans for it in K now, doesn't mean it's not useful for them in the next release.01:06
hemnaand I thought the main idea of cinder is to get vendors to help add features to cinder itself to make it better.01:07
thingeeI think this information and understanding is fair for me to ask. If you're unsure of me asking this, then that really worries me about this working for other vendors.01:07
hemnaso I'm confused01:07
hemnaI'm not concerned about asking about the feature and how it works, how folks want to use it.01:07
thingeeok great. so why are we arguing?01:08
hemnaI guess what worries me is threatening to remove something because you can't get feedback from others.01:08
hemnait's not something we can control01:08
thingeeI think it's completely valid to understand how something is going to be used. If I can't understand that, I don't want it part of Cinder.01:08
thingeeunfortunately it requires feedback and I think xyang will be happy to share that information01:09
xyangwe are interested in this blueprint.  we actually were thinking about implementing it ourselves if it was not already done by HP01:09
hemnawell sure, understanding how something works is critical for cinder and everyone moving forward.01:10
hemnaso yah, lets get feedback from folks and move forward from therem.01:10
thingeehemna: truth is, I don't think it will be removed. I'm more setting worse case so that's understood now rather than me freaking out march 19th. I just really would like to get this information now from people.01:11
hemnayah that works for me.01:12
hemnaat least we have the opportunity to have this discussion now instead of at the K3 deadline.01:12
hemnawhich is how lots of core features landed in the the 3rd deadline, where no driver maintainers had a chance to look at it and provide driver support for it.01:13
thingeehemna: so with 1-100 that can be reported. In a multi-vendor environment, how is it determined of what one vendor considers a "70", from what another vendor considers what a "70" is?01:13
thingeeor am I still not understanding this01:13
hemnathat 70 means the same thing for each vendor01:13
hemnait's a unified #01:14
thingeeI'm not even asking for actual driver code to be posted from other vendors. Just want to understand at a high level of how people plan to write support for this and if they really understand that it'll work for them and not limit their driver.01:14
tbarronhow a unified number? "each backend to return two new functions when reporting capabilities/status, and those will be used for filtering and weighing."01:16
hemnabasically any # above 50 means sure, I can probably take the next volume01:16
hemnaless than 50 means...well I'm starting to not want another volume on my array01:16
hemnabut that # is configurable by the admin01:16
hemnaas they define how the goodness function is calculated01:16
*** tsekiyam_ has joined #openstack-cinder01:17
hemnaso if an admin only wants N volumes on the array, then they bake that into their goodness function01:17
tbarronso admin is defining the function, not the backend vendor?01:17
hemnatbarron, yes01:17
hemnatbarron, the spec also says "An equation in string form that when evaluated using5601:17
hemna                           PyParsing will be a value between 0 and 100."01:17
tbarronso netapp can't always return 99 to own all your bytes?01:17
hemnathe netapp code won't01:18
hemnaif the admin programs the goodness function to be that, then that's what they want and will get.01:18
tbarronsorry, i know I'm coming in late :-)01:18
hemnaif netapp provides a patch that returns 99 in their goodness function declaration, then we'll see that in review.openstack.org01:18
hemnaand call em out on it.01:18
tbarronso there;s a common semantics b/c the admin is in charge01:19
hemnathe admin knows their backends01:19
hemnabswartz, :P01:19
tbarronkk, my only concern would be the (apparent) complexity01:19
hemnawhy is netapp always the 'bad guy' in theoretical discussions?01:19
tbarronhemna: I work for netapp, so didn't want to pick on xing or kurt01:20
bswartzwe've been here a long time01:20
bswartzand there's no such thing as bad publicity01:20
*** mtanino has quit IRC01:20
*** tsekiyama has quit IRC01:20
bswartzso bash away01:20
tbarronbswartz: don't get any idea01:20
hemnaanyway, I have to head home.01:20
thingeebswartz: how do you plan to use this?01:20
hemnaDuncanT, understands the idea just as well01:21
bswartzit is better to be hated than to be ignored01:21
*** tsekiyam_ has quit IRC01:21
tbarronbswartz: no comment01:22
bswartzthingee: to use what? I just popped in and saw the jokes about netapp stealing all your bytes01:22
*** hemna is now known as hemnafk01:22
bswartztbarron: that's a famous quote from someone01:22
bswartzI can't remember who01:22
bswartzthingee: oh this01:23
bswartzthis feature makes me sad01:23
bswartzit feels like an admission of defeat01:24
bswartzthat the existing filter scheduler doesn't work well enough01:24
thingeebswartz: it would've been great to get your feedback back on
bswartzI imagine that some useful features can be built using this mechanism, but I'd rather that backends actually returned useful capabilities and the filter scheduler filtered/weighed them to arrive at the outcome01:25
*** david-lyle has quit IRC01:26
bswartzthingee: I don't feel like the feature is a bad idea by itself, but I think it would have been an unnecessary one if we worked harder on reporting capabilities01:27
thingeewhich we are working on.01:27
bswartzmaybe a "goodness" function can serve as a reasonable default for administrators who can't be bothered to turn their brains on and write decent weighers/filters01:28
bswartzbut different deployments will have different requirements and a goodness function is by definition one-size-fits-all01:29
bswartzthe case I'm most interested in seeing a scheduling based on performance headroom01:30
bswartzthat's an extremely complicated topic, but I think it would be desirable to users01:30
tbarronbswartz: 'performance headroom' => load-balancing?01:31
openstackgerritVilobh Meshram proposed openstack/cinder: Introducing micro_states for create workflow
bswartztbarron: for one definition of load, yes01:38
*** rwsu is now known as rwsu-afk01:39
bswartzwhat makes performance-based scheduling so fiendish is that I/O workloads can change dramatically from 1 instant to the next01:39
bswartzyou can have a storage node that looks nice and calm and then all of a sudden some tenant decides to run iobench against it01:40
bswartzso it needs to be combined with some sort of qos controls and some sort of average-over-time monitoring to get reasonable results01:41
tbarronseriously, I do endorse the request for use-cases, as I think administrators are very busy, they won't have time to write decent weighers/filters, or (I fear) a sensible cross-backend goodness/filter functions.01:41
tbarronbswartz: completely agree about the volatility of performance-based scheduling01:42
thingeeI agree with hemnafk this is late in discussion, but there's not wrong with discussing something, especailly if it hasn't been released.01:42
tbarronthingee: +101:42
thingeeand if people are unsure how this would work for the administrator, why make things more complex?01:42
*** scottda_ has quit IRC01:43
bswartzthingee: I wish more administrators were represented on this team01:45

p01s0nOn centos 6.6 icehouse , cinder is failing to attach volume to instance as it tries to find lun-1 which is not present and only lun-0 is available in /disk/by-path/  any idea about this behaviour05:41

anishp01s0n: according to this, it is looking for lun-0 by default, not lun-1

DuncanTThingee: Unfortunately you were discussing it at 3am my time, but I've added a fairly detailed comment to the filter/goodness function driver side review that I hope helps, including a few examples. The one area I have that is somewhat divergent from last night's discussion is that I think vendors can provide useful default functions, particularly filter10:07

DuncanTThingee: I'm fine with goodness functions being left up to the admin if we see them as too contentious, but I really feel there is value in vendors being able to give good default  filter functions, even if it takes time for them to actually do so, so I'd like the mechanism baked in from the start (which I don't see how to do with the current patch, hence10:09

jgriffithany volunteers for the IET driver?  Or am I going to be stuck with it :)21:55
anishjgriffith: would also avoid some confusion I think. like the chap_username/password for scst look generic but only work for scst21:55
jgriffithanish: yeah, we're way better than having these embedded in the driver IMO, but still have some work to do21:55
mtaninoohhh, IET....21:55
jgriffithmtanino: :)21:55
anishjgriffith: possibly, does it have to be by k3 ?21:55
