smcginnisjordanP: What's up?13:26
smcginnisjordanP: Guessing this? https://review.openstack.org/#/c/200610/13:27
jordanPsmcginnis, hi :) I didn"t quite understand one of your comment you left me13:27
smcginnisjordanP: Sure, which one?13:27
*** jwcroppe has quit IRC13:27
jordanPsmcginnis, the six.str_type13:27
jordanP(thanks btw)13:27
smcginnisnp13:28
jordanPI have submitted another patch but I am not sure it addresses your point...13:28
smcginnisjordanP: I see your response.13:28
smcginnisjordanP: So forcing it is discouraged when passing it in to the logger.13:28
smcginnisjordanP: Mainly because internally the logger will do it again, so it's redundnant.13:28
smcginnisjordanP: And if the log level is set higher it might not ever need to do it.13:29
smcginnisjordanP: But in the case I pointed out you are performing string formatting directly.13:29
*** timcl has quit IRC13:29
smcginnisSo it won't be deferred and it won't be handled by the logger.13:29
jordanPyeah I think the logger does something because I can't make to raise a Unicode error or something13:29
smcginnisIn that case it could potentially cause an exception.13:29
*** mriedem has joined #openstack-cinder13:29
smcginnisjordanP: I had a paste somewhere that was able to reproduce the Unicode error when _not_ using the logger and just doing string formatting.13:30
smcginnisNot sure where that is now.13:30
*** Yogi1 has joined #openstack-cinder13:30
smcginnisjordanP: That said, this was in the existing code and hasn't been an issue so far, so no worries if you don't address it.13:30
* smcginnis hasn't seen the latest update13:30
smcginnisjordanP: Just thought I should point it out.13:31
jordanPyeah but even in the exception ' raise exception.VolumeBackendAPIException(data=msg % e)' I am doing string formating but even if "e" contains Unicode char, "it works" (I have a unit test that covers this)13:31
smcginnisjordanP: Hmm. I did have code that would reproduce the error at one point. If I get time I will track that down or redo it.13:32
*** BharatK has joined #openstack-cinder13:32

lixiaoy1:smcginnis may I talk with you about creating encrypted volume from image?13:35
smcginnislixiaoy1: I haven't done much with encrypted volumes.13:35

*** breitz1 has quit IRC13:36
*** crose has joined #openstack-cinder13:37
lixiaoy1:smcginnis anyone is OK. :) I found that when creating an encrypted from image, it just writes unencrypted data into the volume which as a result Nova can't boot from it13:37
smcginnislixiaoy1: Sounds vaguely familiar. I think someone else was running in to this recently.13:38
lixiaoy1I think we can read the unencrypted data from image, encrypts and writes to a encrypted volume. This is what I want to do13:38
smcginnislixiaoy1: I don't know the specifics here. Anyone else around know anything?13:38

lixiaoy1this case is just for creating encrypted volume with image.13:44

jgriffithtbarron: Well... except that patch I referenced and gave a -1 that you then promptly gave a +1 I pointed out that all it did was short circuit the abc class that is in place17:41
tbarronjgriffith: does that make sense?17:41
eharneyjust submitted it as two patches so that we can separate a) fixing a bug vs b) people hashing out the abc details further17:41
*** p0rtal has joined #openstack-cinder17:41
jgriffithtbarron: making it absolutely useless17:41

tbarronjgriffith: yeah, but does that do any real harm?17:42
tbarronjgriffith: only if we keep it17:42
jgriffithtbarron: eharney so again.... the multi-class abc stuff is flawed, and just ignoring it isn't "fixing" your nfs problem17:42
jgriffithtbarron: eharney you guys need to decide you're in or out on the multi-class abc thing17:42
jgriffithtbarron: eharney you can't have it both ways17:42
*** iurygregory has joined #openstack-cinder17:43
jgriffithwhich is what I tried to propose last week17:43
eharneythis isn't trying to have it both ways, and i still don't really see it as flawed17:43
eharneythe problem is that retype() isn't abstract17:43
eharneywhich is much different from something like consistency groups17:43
jgriffitheharney: you just completely circumvented it here: https://review.openstack.org/#/c/206559/17:43
jgriffitheharney: by implementing it in the base class with a true imply the abc decorator will always work, it now does nothing17:43
eharneyretype isn't an abstract method... so i'm not sure why it should be in an abc class17:43
jgriffitheharney: which was my point last week that all these classes for each feature are rather silly17:44
tbarronI thought last week we agreed that there were things that needed to be fixed and cleaned up but that, all things considered, we were moving ahead with what agreed to in Kilo.17:44
eharneyi still think the general theory makes sense for optional features17:44
*** annegentle has quit IRC17:44
jgriffithand that's fine17:45
jgriffithbut it makes no sense to submit a patch that intentionally circumvents the check that is in place, unless you remove that check in the same patch IMO17:45
jgriffithall you did was created a dead piece of code17:45
eharneyit's not circumventing a check... it's putting a method into a class where it needs to exist17:45
eharneywhich code is dead?  the NFS driver uses the method in the base class, other drivers still pull from RetypeVD until we decide if we are keeping that or ont17:46
eharneynot*17:46
jgriffitheharney: but the whole point of the abstract class "retype" is to enforce imply in the drivers that inherit form it.  If you impl it in the base class that EVERY driver inherits then it does absolutely nothing17:46
jgriffithand it is in fact circumventing the check... which is why you did it to make NFS work17:46
jgriffitheharney: so that's my point!!!17:47
eharneythe NFS driver didn't have a check, because it doesn't inherit from RetypeVD... it's not circumventing anything...17:47
jgriffith the NFS driver uses the method in the base class, other drivers still pull from RetypeVD17:47
jgriffith^^  your quote17:47
jgriffithWhat's the point if we just say... "we have this.. but you can just work around it and not inherit it and do your own thing"17:47
*** earlephilhower has quit IRC17:47
jgriffithI don't understand, all this does is just continue to make things more confusing and difficult to follow17:48
eharneythe goal is to have all drivers inherit from the appropriate abc classes, but we haven't gotten that far with implementation yet17:48
eharneynobody is going to port all the drivers when everyone is still arguing over whether they like using abc in general17:48
jgriffithdriver A may or may not be using the abc meatballs... but it still implements the feature defined in the metaclass17:48
jgriffithwhile driver C does it a different way17:48
jgriffithand so on and so on17:48
eharneythe metaclass was wrong, though17:49
jgriffithNobody is arguing, you all rejected my change proposal promptly17:49
eharneyRetype doesn't make sense as a metaclass17:49
eharneythough i left plenty of room on the review for someone to come tell me otherwise17:49
jgriffithI agree.. none of the features as metaclasses make sense IMO :)17:49
jgriffitheharney: I'm saying your first patch need to remove it17:49
jgriffiththat's all17:49
jgriffithnot hack around it17:49
tbarronall three of us are for removing it, I just didn't have a problem with it being two reviews to get it done17:51

tbarronscottda: handy for when you have devstack w/o swift enabled and you need to run backup tests19:58
DTadrzak_Well I think that i'm so tired and i need to rest. I don't know why did I saw OBJ_SERIAL_NAMESPACE instead of OBJ_PROJECT_NAMESPACE . Nvm. ;)19:58

strony-zhangAgain. Generally, how long does restoring  an backup of 1 GB volume take? The backup driver  is swift.22:00
jgriffithstrony-zhang: I'd answer if I could.... I know the cinder-backup operations are pretty slow; but for 1G it shouldn't be bad22:02
jgriffithstrony-zhang: depends on your bandwidth / read throughput from SWIFT and of course the dd to the volume22:02
jgriffithstrony-zhang: things like cinder backend make a difference, network topology etc22:03
jgriffithhemna: dang you!!!  :)  I have a version of that detach patch half done...  then went to meetings :(22:04
strony-zhangThanks John. In the same area, like Bay area, in my tests, restoring 1 GB volume takes 15 minutes. Is that normal?22:05

jgriffithstrony-zhang: but I wouldn't be surprised; and no I don't have any real experience with it.  I used device optimized backups22:08
thingeeharlowja: are you doing a 0.6.2 release?22:09
jgriffithstrony-zhang: I have heard that a 200G volume can take over 20 hours22:09

openstackLaunchpad bug 1484267 in taskflow "taskflow 0.6.1 has uncapped networkx which breaks cinder py26 unit tests in juno" [Undecided,Confirmed]22:09

hemna_jgriffith, https://review.openstack.org/#/c/212193/  I don't see any inline comments ?22:10
vilobhmmthingee : harlowja is away on vacation..someone or sputnik13 on #opestack-state-management should be able to answer22:10
jgriffithhemna: I made some comments on your detach patch.  Good idea moving it into the DB layer, but I think you missed a few other calls that use that exception22:10
strony-zhangjgriffith: Backup seems to be better than restoring. Thanks.22:11
jgriffithstrony-zhang: cool22:12
jgriffithstrony-zhang: sorry I don't have more concrete info for you22:12
strony-zhangjgriffith: for the backup, I almost got the same performance, 6minutes for 1 GB. For the restoring, it will take more time. Thanks, John. :)22:14
