jgriffithvinayp: Ahh... I see what hemnafk is asking for here, makes sense.  Refactor those checks you added up into the base class (InitiatorConnector) to ensure the lun number is checked/converted regardless of which connector type is being used.05:03
jgriffithvinayp: not sure it's applicable to anything but iSCSI and FC but regardless05:03
*** shausy has joined #openstack-cinder05:03
jgriffithvinayp: also to avoid confusion WRT the regex, you might want to consider just using something like "if '0x' in lun:  ....."05:04

chhaviblock_device_mapping_get_by_volume_id() Line 403011:28
chhaviHere currently we are picking first() but if the volume is shared then we might expect multiple BDM entries11:29
chhaviwhich is valid11:29
ildikovwhat you miss there is that the search includes the instance_uuid11:30
ildikovwhich identifies the BDM, there should not be more11:30
*** alonma has joined #openstack-cinder11:30
ildikovthere's a problem though with BDM uniqueness, but that's a generic issue11:30
chhavisorry i mean line 404111:30
chhaviblock_device_mapping_get_by_volume_id11:30
ildikovyeah, in that case that's true11:31
chhaviwhere user wants BDMs by volume_id11:31
ildikovthat's an existing function I cannot modify it11:31
ildikovthe solution here is not call it if possible11:31
openstackgerritSzymon Borkowski proposed openstack/cinder: Update terminate_connection to use volume object  https://review.openstack.org/26479711:31
ildikovthe only function it uses it and where we dont have instance_uuid in place is create_volume_snapshot11:31
ildikovthat's disabled for now with multiattach volumes11:32
chhaviin that case i think it will be good to add a new query to get_all11:32

chhaviit can be used to identify if the volume is shared or not11:36
chhaviif multiple entries that means volume is already attached11:36
ildikovnot necessarily, there are race issues in the code11:36
ildikovI use the volume info in every case for that11:36
ildikovthat's the let's say ultimate source of truth11:37
ildikovas I said BDM uniqueness is not a solved problem today, there are patches up for review for it, but they'r enot merged yet11:37

ildikovchhavi: I know, but the multiattach flag is stored only in the volume for instance, so that's required anyway12:14
ildikovchhavi: on the other hand a volume can be attached to a host too, not just to a VM instance12:15

chhaviildikov: whether volume is attached to the host or to the instance, BDM for an instance will be unique.12:16
*** raildo-afk is now known as raildo12:16
chhaviFor example: if a single volume is attached to multiple instances each having their own BDMs then this should return all the BDM entries12:16
ildikovchhavi: but does not tell the information correctly about a volume still in the sense of it is already attached or not12:16
chhavisince previously we do not support shared volume it was meant to return a single entry12:17
chhaviildikov: If there is a BDM entry having the volume-id, it means that instance is attached to the BDM.12:18
*** EinstCrazy has joined #openstack-cinder12:18
chhaviDuring volume detach we update the BDM info12:18
ildikovI got it, but still I need the volume info anyway, therefore it's better to check that if the data is there anyway12:22
chhaviildikov: remove_volume_connection: https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L491212:24
chhavihere we are using this12:24

ildikovchhavi: I got it, but I still don't see the value at this stage of that extra function, also that call you referred will return only one BDM in any case12:26
*** EinstCrazy has quit IRC12:28
ildikovchhavi: there's also a this check and note here: https://github.com/openstack/nova/blob/master/nova/objects/block_device.py#L207, I wonder what case it was needed for12:28
ildikovs/was/is/12:28
ildikovanyway, what you're saying could be an optimization if we could save one round trip with it, but we can't12:29
ildikovBDM is very fragile in Nova12:29
*** coolsvap is now known as coolsvap|away12:34
chhaviildikov: I need to check more details on the same, because i did not see any such behavior for BDM till now12:37
chhavithe one u mentioned stands only when we upgrade,12:37
chhavilet me go through the details of the BDM change set shared for more clarity12:37
chhaviildikov: thanks for sharing this info12:38
ildikovchhavi: I'm not experienced enough, I can only rely on the concerns of the cores12:38
ildikovI mean in Nova12:38
ildikovwhat you suggest can be done later, when we get there to optimize12:38
chhaviyeah i understand, me too learning updated the review comments to hear some more inputs from john on the same.12:39
ildikovthe non-priority feature freeze for Nova is Jan 21, so until that I fix only what's critical and I'm still afraid even a mimum setup will not make it again :(12:39

mriedemjgriffith: i was reviewing the nova spec last night14:55
mriedemsince i never reviewed it the first time before it was approved14:55
jgriffithmriedem: ahhh, I see14:55
johnthetubaguymriedem brought up some good new points the other day, but I think ildikov has mostly patched those, or was about to14:56
ildikovjohnthetubaguy: yes, I did14:56
mriedemjohnthetubaguy: i raised a concern about minimum required libvirt in the amended spec change last night too14:56
mriedemi'd like danpb to weigh in on that14:56
jgriffithjohnthetubaguy: cool, so we need to figure out a better model for Cinder/Nova at some point I think.14:56
ildikovjohnthetubaguy: the only thing I'm playing with now is the libvirt version check14:56
johnthetubaguyildikov: mriedem: was there a boot from volume thing that needed sorting out, or were we happy about that now?14:56
jgriffithjohnthetubaguy: we're a bit too "loose" on our side at times I think, and there are more complex relationships between the two these days that make these changes a pain14:57
jgriffith"our side" == "cinder"14:57
ildikovjgriffith: when the spec landed we agreed to have a working version even with more limitations and then refactor later, where possible to have smt more optimal than now14:57
jgriffithildikov: hey... don't get me wrong, not negative comments about what you and everybody else have done14:58

jgriffithildikov: I was just thinking out loud that we should do something more organized in our API's between Cinder/Nova in the future to make these sorts of things go smoother, and address some of the compat issues that mriedem just pointed out14:58
ildikovjgriffith: sorry, I spent too much time with it in the past few weeks and on the other hand I also see it's not a straight forward activity in any sense14:59
jgriffithildikov: I hear ya14:59
ildikovjgriffith: yeah, I think I or someone else addig this topic to the mid-cycle too to have a cross-project discussion about this14:59
johnthetubaguyjgriffith: we are having similar "coupling" struggles with neutron APIs in a similar way, things like brick and os-vif-lib are helping some, but I think we probably need to go a bit further, but the fact we are talking about it these days gives me hope :)14:59

jgriffithand FWIW I never quite followed the logic when they argued for it either16:34
*** lcurtis has joined #openstack-cinder16:34
dulekSo metadata are used internally to do a lot of things.16:34
dulekFor example metadata on flavor can express hardware requirements.16:35
jgriffithsure16:35
dulekYou can also set a lot of metadata on images in Glance.16:35
dulekThese are used for example when booting a VM directly from an image.16:35
dulekLet me find an example…16:35
jgriffithdulek: used by Nova?16:36
jgriffithdulek: here's the thing that's always bugged me....16:36
dulekhttps://github.com/openstack/nova/blob/master/nova/scheduler/filters/image_props_filter.py#L106-L10716:36
dulekThat's an example.16:36
jgriffithdulek: we have:  volume_metadata, volume_admin_metadata, volume_glance_metadata, snapshot_metadata, snapshot_glance_metadata, service_metadata....16:37
jgriffithIt's a bit out of control IMHO16:37
hemnacan we get metadata_metadata ?16:37
dulekOkay, so just let me finish with glance ones. ;)16:37
jgriffithhemna: I think we have it :)16:37
dulekhemna: metametadata16:37
hemna:)16:37
jgriffithdulek: yeah, so that example helps16:37
dulekBut there's more.16:37
jgriffithdulek: but here's what annoys me about it...16:37
dulekYou can for example request certain amount of RAM allocated to graphics through image metadata.16:38
jgriffithdulek: this is the same case.... we already have glance_property (they don't call it metadata) so why aren't we just uploading that as generic info?16:38
jgriffithdulek: rather than creating all these references16:38
jgriffithdulek: or just embed it in the snapshot/volume metadata that we already had16:38
jgriffithvolume_metadata = {glance_prop: {....}}16:39
dulekjgriffith: Yeah, that would probably be better.16:39
jgriffithor I guess s/glance_prop/image_prop/16:39
dulekBecause we're storing glance_metadata to pass them to nova when booting from volume.16:39
dulekAnd on snapshot to copy them to a volume when creating it from a snapshot.16:39
jgriffithdulek: ok, well thanks for helping me with that16:40
dulekAnd probably to copy them back to Glance when copying volume to image.16:40
*** dslevin has joined #openstack-cinder16:40
jgriffithdulek: I wanted to make sure there wasn't something I was missing somewhere16:40
dulekI haven't ever thought of how to do that in a proper way.16:40
dulekIt was like "there" when I came in to the project. ;)16:40
jgriffithI guess I don't understand like I said why the sub key in the metadata wouldn't be fine?16:41
jgriffithso you just have snapshot_metadata and volume_metadata16:41
johnthetubaguyFWIW, we have an object for that stuff thats in glance now: https://github.com/openstack/nova/blob/master/nova/objects/image_meta.py16:41
jgriffithget rid of all the crazy other ones16:41
jgriffithjohnthetubaguy: looking...16:41
dulekI think it's bound to 255 chars, so that would probably be a little small space.16:41
dulekI mean - metadata key.16:42
jgriffithdulek: true16:42
*** dslevin has quit IRC16:42
jgriffithdulek: but there has to be a better way than what we're doing now... looking at the nova code johnthetubaguy just mentioned16:42
*** dslevin__ has joined #openstack-cinder16:42
jgriffithjohnthetubaguy: dulek ok, so this seems like it would be wayyy better16:43
dulekLet me take a look…16:43
jgriffithUse a full image_metadata (or image-property) table16:43
jgriffithand backref that to a volume or snapshot or whatever16:44
jgriffiththat also means it's got a chance at being something that's standardized and enforced16:44
dulekYeah, looks great… But how to keep the list in sync between Nova, Cinder and GLance?16:44
jgriffithas opposed to just a bunch of random stuff that people shove things in to16:44
dulekI mean - when Nova adds a property key that does something we would also need to do su.16:44
duleks/su/so16:44
jgriffithdulek: so that's something else that troubles me :)16:45
jgriffithdulek: there's no real single source of truth right now16:45
jgriffithwell... I guess Nova would be16:45
*** dslevi___ has joined #openstack-cinder16:45
jgriffithbecause.. well, that's what really need/uses this data16:45
jgriffithI hate to say this... but it makes me think that this should actually be a shared library16:46
jgriffiththat way everybody is synced up off of one single version16:46
dulekThere are some descriptions in Glance also that are used to display properties in Horizon metadata view.16:46
jgriffithor we just stay in lock step with what Nova has16:46
jgriffithdulek: well... so here's where my selfishness comes in16:46
*** timcl has quit IRC16:46
jgriffithdulek: I've been burned by Glance enough in the past changing their properties and breaking them that I'd prefer they didn't own them :)16:47
dulekIf we have a DB column per property, then that lib would need to add migrations and stuff when things change. This gets a little complicated.16:47
jgriffithdulek: yeah, it's certainly not trivial16:47
*** dslevin__ has quit IRC16:47
dulekNova should certainly own them. Just mentioning Glance is having a catalog with them also.16:47
jgriffithglance should just go away... and be absorbed by modules in Nova :)16:47
* dulek thinks of Glance like a Swift API. ;)16:48
jgriffithI16:48
duleks/like a/like of16:48
*** edtubill has joined #openstack-cinder16:48
jgriffithYeah, but then they decided to be more.  And you run into issues because there's Ceph, NFS etc16:49
jgriffithhmmm16:49
dulekAnd speaking about the bluex patch you've mentioned in the beginning - it's just synchronizing objects with what's in DB.16:49
dulekAnd to be honest it's not that critical now - just kind of refactoring.16:50

smcginnisscottda: Jenkins hasn't reported on that yet, has it.16:58

leeanthojgriffith, the tool would be used by an admin/developer/tester/CI who want to verify that attach and detach operations are not leaving volume paths behind.  The problem originally came up with live migration testing a while ago but could be useful for other attach/detach scenarios.  I've had the patch for the tool in os-brick for some time but that might not be the best place for it to exist even though it uses brick APIs.19:11
*** cfriesen__ has joined #openstack-cinder19:13

*** gouthamr_ has quit IRC19:15
leeanthoIt was mainly to help automate the process because sometimes paths were only intermittently left behind.  Instead of having to do the same steps many times manually (if doing something like 100+ tests) you could automate calls to the tool to verify and check after each attach/detach or live migration attempt.  That could then just keep track of pass/fails for the attempts (outside of that brick tool)19:16
leeanthobrick also made it easier to check different connector types outside of iscsi with its apis. some connectors use different  locations for volume paths19:19

mtreinishjgriffith: I just had a random idea/question have you tried to run openstack-health ontop of your subunit2sql db from sos-ci?20:22
jgriffithmtreinish: no, I haven't actually looked at openstack-health20:23
jgriffithreading up on it now20:23
*** chris_morrell has joined #openstack-cinder20:23
mtreinishjgriffith: http://status.openstack.org/openstack-health/#/20:23
*** alonma has joined #openstack-cinder20:23
jgriffithmtreinish: oh happy!!!20:23
jgriffithOk, yes... I want that!!!20:23
jgriffithmtreinish: in fact, I want it to be mandatory for ALL the CI's20:24
smcginnisNice!20:24
mtreinishit might not work 100% for your db because it does expect certain values in the run metadata20:24
jgriffithmtreinish: well, I can certainly *adjust* things20:24
mtreinishlike build_name: XXX and project: XXX20:24
jgriffithmtreinish: ok, cool... I'll def take a look at adding this in20:25
mtreinishcool20:25
jgriffithmtreinish: that reminds me, I've still never pushed the round of commits for the latest stuff I added in it for subunit etc20:25
jgriffithmtreinish: I'm curious...20:26
openstackgerritMerged openstack/os-brick: Actually log the command used in _run_iscsiadm  https://review.openstack.org/26431020:26
jgriffithmtreinish: how is pass rate being calculated (far too lazy to look) :)20:26
*** chris_morrell has quit IRC20:26
jgriffithmtreinish: I ask because for example genuine patch induced failures20:26
mtreinishjgriffith: so this is only from gate (thats all we collect in the infra subunit2sql db)20:26
jgriffithI'm assuming these are part of verify not gate?  Or am I wrong20:26
mtreinishand only tempest runs20:26
jgriffithok20:26
jgriffithcool20:27
mtreinishit also misses failures before tempest starts, because we need a subunit stream to write into the db20:27
mtreinishbut I'm working on that aspect with: https://review.openstack.org/#/q/status:open+project:openstack-dev/devstack+branch:master+topic:devstack-subunit20:27
mtreinishand then a corresponding thing for d-g when that's working20:27
jgriffithmtreinish: so one thing about that, is it would be cool if some day we had a way to convey what failed...20:28
*** alonma has quit IRC20:28
jgriffithie if it was a random test failure, stack.sh or something introduced by the patch20:28
mtreinishand collecting more than tempest is just a matter of config: https://github.com/openstack-infra/system-config/blob/master/modules/openstack_project/files/logstash/jenkins-log-client.yaml#L14-L2520:28
jgriffithI know that's a pretty pie in the sky request :)20:28
jgriffithmtreinish: ok, doesn't look like any of those should be difficult to NOT have a translation over to sos20:29
jgriffithmtreinish: or.. well... you know what I mean :)20:29
mtreinishheh, I have an idea on how to do that that leveraging elastic recheck and doing an on demand query to logstash20:29
jgriffithmtreinish: :)20:29
mtreinishall the data to do that is in the db, but it pushes my js scripts too far20:29
mtreinishs/scripts/lack of skill20:30
jgriffithmtreinish: :)20:30
jgriffithI was doing some stuff to just leverage out a keyword list20:30
jgriffithbut it's pretty basic20:30
jgriffithI just comb my ansible output to see if I ever get the success response from stack.sh20:31
jgriffiththe random failure thing... well, that's a whole different story:)20:31
mtreinishI have patches up to start adding a list of recent runs w/ links to the logs: https://review.openstack.org/26438320:31
jgriffithmtreinish: I started playing with building a list of known "troulbesome" tests but I don't like that20:31
jgriffithmtreinish: hmmm20:32
* jgriffith has never wanted to learn js... but 20:32
mtreinishjgriffith: heh, that's simple it's always test volume boot pattern at fault :)20:32

mtreinishah the generic failed to ssh error20:33
jgriffithanyway... some day I'm going to figure out how to make that sucker stable20:33
jgriffithyes!  I was thinking of adding an ssh retry loop... didn't see if that was already in Tempest20:34
mtreinishsdague and I were talking about some improvements to the logging that are really needed there to make figuring out why it cant connect easier20:34
mtreinishbut that ssh code is a ratsnest and really needs a simplification/refactor20:34
jgriffithreason being is that in my ci for example I kept hitting the pitfall of thinking "ACTIVE" was actually ready20:34
mtreinishjgriffith: it does a retry loop with an exponential backoff20:34
jgriffithdamn20:34
jgriffithmtreinish: I kinda figured folks were smarter than that20:35
jgriffithmtreinish: but I still had "hope" :)20:35
mtreinishjgriffith: here's an example: http://logs.openstack.org/57/257557/7/check/gate-tempest-dsvm-neutron-full/b35e1bb/logs/tempest.txt.gz?level=WARNING#_2016-01-08_19_50_17_22720:35
