*** raunak has joined #openstack-cinder04:07
jgriffithlixiaoy1: yeah... sorry, not really that it's restarting... but it's initializing the DB over and over.  that second line in the paste04:08

lixiaoy1jgriffith: what is the intersting error?04:21
ManishDGood morning Cinder04:22

openstackLaunchpad bug 1617442 in Cinder "Manage existing volume fails with MissingDependencies" [Critical,In progress] - Assigned to Chuck Fouts (fchuck)14:59
*** nkrinner has joined #openstack-cinder14:59
*** alonma has joined #openstack-cinder15:01
cFoutsDuncanT: basically the create_with dict in get_flow defines the parameters that are passed to tasks in a linear task flow. Each task can also add additional parameters in a list called default_provides. If a task (execute method) expects to receive a parameter named 'volume' but doesn't it will throw a MissingDependency error15:02

krotscheckHey, I'm doing some work against the cinder API right now, and I'm looking for a little historical context.16:10
krotscheckWhen I retrieve the service catalog from devstack's keystone, I get a URL that looks like this: http://192.168.99.99:8776/v1/8b2aa635109f4d0ab355e18a269d341f16:11
krotscheck(for cinder)16:11
hemnaeharney, so I did a little hunting on shred vs dd and I didn't find any consensus why one was better over another16:11
krotscheckHowever http://192.168.99.99:8776 return http://192.168.99.99:8776/v316:12
krotscheck(Adjust ersion numbers as appropriate.16:12
eharneyhemna: for our cases, shred is not providing anything useful16:12
openstackgerritHelen Walsh proposed openstack/cinder: VMAX Plugin - Target WWN change for redundancy  https://review.openstack.org/34230016:12
krotscheckWhat's the significance of the additional suffix found in the devstack catalog?16:12
hemnaeharney, I was under the assumption that safety against data leakage was the reason to use dd/shread after we were done w/ the volime16:13
hemnavolume16:13
hemnanova code does the same thing16:13
eharneyhemna: if people want more safety than dd provides, they should just use volume encryption, we don't know that the cost of running shred does anything significant anyway since it greatly depends on what's going on in the storage backend16:14
eharneyhemna: now that everyone has fancy dedup-ey backends you can't really shred over your data anyway16:14
*** raunak has joined #openstack-cinder16:15

krotscheckscottda: Yep, I can see that.16:16
hemnacool, I was just curious.  I don't really care either way16:17
krotscheckscottda: Really, what I'm trying to do is create find the root URL for all services from the catalog, so I can query the list of versions and negotiate the one that I know how to talk.16:18

scottdaThat's my token16:20
krotscheckscottda: That's unique to cinder best I can tell.16:20
scottdaI stole it from Manila, so maybe the same for them...16:20
krotscheckscottda: Gotcha. So I can happily ignore it if I provide the token via the x-auth-header?16:21
scottdaBut we need something for services with microversions, so the user can discover what (micro)versions the sever supports.16:21

hemnaisn't deprecation supposed to leave the capability in and then remove it later16:54
hemnathe patch removes shred entirely.16:54
hemnaand switches it to dd.16:54
hemnathat doesn't seem like a deprecation, but a removal ?16:54
hemnado we care?16:55
hemnasmcginnis,16:55
smcginnishemna: I haven't looked. Is the functionality the same, just a different implementation?16:55
hemnathis seems like a grey area to me16:55
hemnathe patch removes shred16:56
smcginnishemna: If it takes away something then definitely it should stay and be removed next release.16:56
hemnabut logs saying it's deprecated and will be removed16:56
hemnaand then switches the functionality to dd16:56
hemnaunless I'm missing something16:56
smcginnisIf the user can still request something but we just happen to do it differently under the covers, then that's different.16:56

*** erlon has quit IRC16:57
hemnayah, grey area16:57
eharneyi dunno, doesn't matter too much how we do the intermediate step to me, just wanted to push it in the right direction16:57
eharneyi also think that nobody has ever set this option to =shred16:58
hemnaI'm not sure how they configure cinder to use shred vs. dd anyway16:59
hemnamust be some conf entry ?16:59
eharneyyeah, volume_clear16:59
smcginnisSo I think since the end result still gives the user what they want and it doesn't break anything, it's OK to just switch this.16:59
smcginnisAnd deprecate the option just in the sense that that config option will go away in O.17:00

enriquetasoHi geguileo, I wonder if you could help me with the 'manage volume' bug. ( /354289/ )18:23
enriquetasoYou are right, manage an already-managed volume is handle in the same way as manage a non existent volume.18:23
enriquetasoBoth of them don't match the volume ID with image ID, but I think it shouldn't be the same case. :/18:23
*** alonma has joined #openstack-cinder18:24
geguileoenriquetaso: Mmmm, but the managing patch doesn't remane the image?18:24
geguileos/patch/path18:24
geguileoenriquetaso: I mean, when we manage a volume, don't we rename the existing image to match the new ID?18:25
geguileoenriquetaso: And why would an already managed volume get an image not found error from Ceph?18:25
geguileoIf we give the right image name?18:26
enriquetasoso so, create a volume and check with rbd: http://pastebin.com/RcFtaR7c ... the rbd id starts with "volume-".. manage only works if "volume-" is present in the syntax18:26
geguileoenriquetaso: I know18:27
geguileoenriquetaso: Then you manage that volume, and we rename it, right?18:27
geguileoenriquetaso: Or Ceph doesn't implement the renaming when managing?18:28
geguileoenriquetaso: Didn't you imlement that functionality?18:28

melwitthi, I was wondering what's the difference between terminate connection and detach? I'm working on a bug where a volume is stuck in-use under certain circumstances and I noticed it doesn't seem to matter whether terminate connection is called, only detach19:55
mriedemjgriffith: ^19:55

mriedemthe api ref is a bit lacking on those actions http://developer.openstack.org/api-ref-blockstorage-v2.html19:56
melwittthat is, if I attach a volume to a nova instance and that instance goes in error state, if I call detach and not terminate, it frees the volume for a later attach. and I was wondering if I should be calling terminate also19:56

patrickeastmelwitt: these might help, hemna made some nice flow charts https://goo.gl/ufSOJq19:58
patrickeastmelwitt: you should call terminate too iirc19:58
patrickeastsome other ones on https://etherpad.openstack.org/p/cinder-nova-api-changes19:59
melwittpatrickeast: cool, thank you. yeah, I figured I'm supposed to but was surprised it didn't seem to make a difference19:59
*** alonma has quit IRC19:59
melwittthis is just in devstack with the standard stuff19:59
mriedemso os-initialize_connection creates the export19:59
mriedemos-terminate_connection removes the export19:59
patrickeastmight depend on the backend as to how required it is20:00

scottdamelwitt: Terminate_connection is what ends up calling the Cinder driver to un-export the volume...20:00
melwittpatrickeast: yeah, mriedem suggested that20:00
mriedemi'm not sure if os-detach does much, on the nova side we disconnect the volume from the host after that20:00
scottdamelwitt: So, if you don't call it, the volume will still be exported and possibly attached to the Nova compute host.20:00
mriedemi think os-attach and os-detach are just state change APIs in cinder20:01
mriedemsame with os-reserve20:01
patrickeastthat sounds right20:01
scottdamriedem: yes, os-detach changes the Cinder DB state to 'available'20:01
melwittokay, so it was just the illusion of devstack then. thanks patrickeast, scottda, mriedem, that's helpful to know20:03
scottdamriedem: you are right, docs don't have info for os-detach. I filed https://bugs.launchpad.net/cinder/+bug/161860920:08

smcginniseharney: Isn't there a need for reverify? recheck sends it back through the check queue, but if it's already passed check and you just need to kick it through gate again, reverify was always good for that.21:22

hemnahas a set of drivers21:24
smcginnisrm -fr *fibre*21:24
hemnabut they aren't drivers, they are subclasses21:24
hemnaI'm trying to add the supported stuffs to em21:24
smcginnisWhere is that?21:24
hemnaI might break this stuff up into 2 patches21:24
hemnaone for the fczm21:24
hemnaand another for the lookup service stuff21:24
hemnait's all a pain21:25
hemnaI don't know why it was written this way21:25
hemnabut the fczm has drivers21:25
hemnabut the lookup service doesn't21:25
hemnabrocade and cisco just extended the base class21:25
hemnaanyway long story, I'm getting infinite imports21:25
smcginnishemna: So... they each have their own lookup service?21:25
hemnableh21:25
hemnayah21:25
smcginnishemna: Fun!21:25
hemnaI might refactor the lookup service stuff21:26
hemnaI started, and then....ratholed21:26
smcginnishemna: Do we need it both places? Or just in the driver load?21:26
hemnamore and more changes21:26
hemnawe do need it in both places really21:26

smcginnisOK. Well, if it ends up being too big maybe we shoot for early O.21:27
hemnaat least this way, we can get the fczm stuff in21:27
smcginnisYeah, that'd be good.21:27
hemnaas soon as I started on the refactor, I'm deep into new interfaces, and new interfaces need new things n stuff21:27
hemnaratehole ensues21:28
smcginnisThanks for detangling all that.21:28
hemnasure21:28
hemnaI'll just get the fczm done21:28

smcginnisWait, that was 2014. I know at least as of this spring, reverify would just retrigger gate queue checks if needed.21:33

ntpttrhey all, I just tried to do a db migration from stable/mitaka to master, but after I pulled down the master code (in devstack) cinder-manage won't work any more22:42
ntpttrgetting this error for any cinder-manage command http://paste.openstack.org/show/564908/22:42
ntpttris this a bug in master? hemnafk do you know why this import error might be happening in brick?22:43
patrickeastthat doesn't look good22:45
ntpttrhmm it does work on my one node devstack setup w/ cinder at master22:46
patrickeastntpttr: looks like https://github.com/openstack/cinder/commit/8107b8529c186865c1ffc2b6eccbec1335e295d2 just merged recently... which is suspiciously named with that import error22:46
