jgriffith | NightKhaos: problem I ran into before though was the scsi refresh | 00:27 |
jgriffith | NightKhaos: not sure if what you came up with gets around that or not, or what it does to the file-system | 00:28 |

NightKhaos | jgriffith: I can understand why they're want this. Means they can dynamically create databases without worrying about pre-allocation. Personally I'd solve that problem by providing thinly provisioned volumes, but that's just me. :) | 00:51 |

NightKhaos | jgriffith: http://pastebin.com/dR5BzGxr | 00:58 |
jgriffith | NightKhaos: hmm... that should work actually | 00:58 |
jgriffith | NightKhaos: if it's just a function of virt-io driver | 00:58 |
NightKhaos | jgriffith: Yeah, it worked just fine in the times I've tried it. It also looks like if you select a size smaller than the disk (e.g. forget the unit), the opereation will timeout. | 00:59 |
jgriffith | NightKhaos: might be a good thing do check with Dberange on... | 00:59 |
NightKhaos | jgriffith: Where can we find them? | 01:00 |
jgriffith | I just looked in dev he's not there... maybe Nova... | 01:00 |
jgriffith | NightKhaos: might be worth a post to the ML? | 01:01 |
NightKhaos | jgriffith: Maybe, maybe. Never done that before. I'm kinda new at this. I just new enough about libvirt and found you could do a volume resize by reseting state without issues with Ceph RDBs... put 2 and 2, and violia. | 01:02 |
jgriffith | NightKhaos: I'm still a bit nervous about what one does on the file-system.... but I guess if they're smart enough to type "cinder extend" it's kinda their problem | 01:02 |
jgriffith | :) | 01:02 |
jgriffith | NightKhaos: :) | 01:02 |
jgriffith | NightKhaos: well, welcome first off.... second off you're doing things right IMO | 01:03 |
jgriffith | NightKhaos: so you can post to openstack-dev mailing list, with the subject [nova][cinder] Extending attached disks | 01:03 |
jgriffith | NightKhaos: and throw your idea out asking for feedback | 01:03 |
jgriffith | NightKhaos: or we can try and grab some nova folks tomorrow.... either way, just so you know this would be next release before anything really happened with it | 01:04 |
jgriffith | NightKhaos: everybody is going into feature freeze right now | 01:04 |
NightKhaos | jgriffith: I've got a reproducable method I can give to ops for the moment, so they'll be happy regardless. | 01:05 |
jgriffith | NightKhaos: sure, that's always good | 01:05 |
jgriffith | NightKhaos: but it would be interesting to propose it back upstream to the community IMO | 01:05 |
NightKhaos | jgriffith: Which is why I'm here! | 01:05 |
NightKhaos | jgriffith: Should i post this to the general list? Or Future Dev/ | 01:08 |

*** albertom-afk is now known as albertom | 14:31 | |

tbarron | i've been learning a lot from your reviews. But what's up? | 14:31 |
geguileo | tbarron: I'm looking at some code you introduced: https://review.openstack.org/#/c/202570/1 | 14:31 |
geguileo | tbarron: Currently in: https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/netapp/dataontap/nfs_base.py#L681 | 14:31 |

geguileo | tbarron: Wanted to run it by you to confirm | 14:32 |
tbarron | sure, please do | 14:32 |
geguileo | tbarron: First the problem: If we have a list of locations and the first location is not an NFS location we will not look at any other location | 14:32 |
*** yrabl has quit IRC | 14:33 | |
geguileo | tbarron: Solution: Replace urls.append(url) and break with continue | 14:33 |

geguileo | tbarron: But I was just looking at that specific patch | 14:35 |
tbarron | But I wrote the unit tests and did the commit, so it's just as much my fault or more !! | 14:35 |
tbarron | geguileo: I'll make a bug unless you already have. | 14:36 |
geguileo | tbarron: You didn't add negative tests | 14:36 |
geguileo | tbarron: No, I wanted to talk it with you first | 14:36 |
*** lpetrut has quit IRC | 14:37 | |
tbarron | fix will be TDD: write the tests that make it fail, then get it to pass with the continue. | 14:37 |
geguileo | tbarron: You can go ahead and file the bug | 14:37 |
tbarron | geguileo: I will. Thanks much! | 14:37 |

geguileo | vincent_hou: Then you'll need to change a lot of code in Cinder | 15:19 |

jgriffith | xyang1: yes | 15:42 |
xyang1 | jgriffith: Good:) | 15:42 |
mtanino | geguileo: your recommendation is init_vendor_properties() just returns a dictionary like a initialize_connection()? | 15:43 |
*** vincent_hou has quit IRC | 15:44 | |
mtanino | geguileo: without using set_vendor_properties(). | 15:44 |

geguileo | mtanino: And in init_capabilites we either add the vendor_ part or just confirm that all keys have it | 15:46 |
*** mriedem is now known as mriedem_away | 15:46 | |
geguileo | mtanino: That way we are sure we are not overwriting any key from standard_capabilities | 15:46 |
thingee | kvidvans: you type it on the etherpad. anyone can edit it | 15:46 |
kvidvans | thanks..will do...Just wanted to confirm | 15:47 |
geguileo | mtanino: And it's easier to see that we are setting capabilites['properties'] to the contents of those 2 returned dictionaries | 15:47 |
geguileo | mtanino: The way it is now it's a lot harder to see that those 2 add their contents to capabilites['properties'] | 15:48 |
mtanino | geguileo: Is it ok for creating a dictionary using existing set_vendor_properties or set_properties? | 15:48 |
mtanino | geguileo: or using it's is harder to read what in the dictionary? | 15:48 |
geguileo | mtanino: I don't follow what you mean | 15:49 |
*** belmoreira has joined #openstack-cinder | 15:49 | |
mtanino | geguileo: current code set properties using set method such as set_vendor_properties or set_properties. | 15:50 |
*** crose has joined #openstack-cinder | 15:51 | |
geguileo | mtanino: Current code is setting it in an instance attribute | 15:51 |
*** salv-orlando has quit IRC | 15:52 | |
mtanino | geguileo: yes. | 15:52 |
geguileo | mtanino: It shouldn't | 15:52 |
geguileo | mtanino: That's why I'm saying to return a dictionary in _init_standard_capabilities | 15:53 |
mtanino | geguileo: and after that set the returned dictionary to self.capabilities['properties'] at init_capabilities()? | 15:55 |
geguileo | mtanino: If you want you can pass a dictionary to _set_properties (and rename it to _set_property since we no longer are setting 'properties' key there) and do the same thing you are doing with set_capabilities but with that variable instead | 15:55 |
geguileo | mtanino: Yes | 15:55 |
mtanino | geguileo: ok, let me consider again. | 15:56 |
geguileo | mtanino: Sure | 15:56 |

patrickeast | hemna: hey | 16:19 |
hemna | so, friendly names SUCK | 16:19 |
hemna | suck suck suck | 16:19 |
hemna | looks like there is a problem with flushing mpath devices when friendly names is enabled | 16:19 |
hemna | multipath -f <wwn/dm-X> doesn't do anything | 16:19 |
patrickeast | crap | 16:19 |
hemna | turn off friendly names and multipath -f <wwn/dm-X> works | 16:19 |
hemna | looks like a bug in the daemon or the userspace multipath tool | 16:20 |
patrickeast | yea that seems pretty weird | 16:20 |
hemna | so I'm going to send the dm folks an email, as they don't seem to have a web site for tracking bugs. | 16:20 |
hemna | dm@redhat.com looks like a contact ? | 16:21 |
hemna | err | 16:21 |
hemna | dm-devel@redhat.com | 16:21 |
hemna | http://christophe.varoqui.free.fr/ | 16:21 |
patrickeast | sounds like a good idea | 16:21 |
patrickeast | although even if it is a bug, would we be able to still use the naming shortcut? | 16:22 |
hemna | so it looks like the /dev/disk/by-id/dm-uuid-mpath-<WWN> does work | 16:23 |
hemna | I'm working on updating my patch to look for that | 16:23 |
hemna | it's there with or without friendly names enabled | 16:23 |
hemna | but I'm also adding a fallback lookup for /dev/mapper/<WWN> | 16:23 |
patrickeast | gotcha | 16:24 |
hemna | and then another fallback to run multipath -ll <original /dev/disk/by-path/holy crap long device path> | 16:24 |
hemna | to try and make this stuff much more robust | 16:24 |
*** zul has joined #openstack-cinder | 16:24 | |
hemna | the problem is friendly names on detach | 16:24 |
hemna | multipath -f <device> does nothing | 16:24 |
hemna | :(!! | 16:24 |
hemna | so a bunch of crap is left around in /dev/disk/by-* | 16:25 |

dannywilson | jgriffith: any progress on parsing of replication_devices values in base class? | 16:37 |
jgriffith | dannywilson: not sure which part you mean :) | 16:38 |
dannywilson | jgriffith: parsing out the replication_devices='backend':['biz', ....] info | 16:38 |
jgriffith | dannywilson: in the list_secondaries call? | 16:39 |
dannywilson | jgriffith: or even at set up time | 16:39 |
aorourke_ | xyang1, I noticed that if you add a volume to a consistency group, then add that same volume to a new cg it immediately overwrites the volume to belong to the new cg. Is this something that could cause issues? Seems like it could be really easy to break consistency. Wouldn't it be best to force the user to delete the volume from the CG before it can be added to a new one? | 16:39 |
dannywilson | jgriffith: is there an easy way to parse those out? I might be missing a simple explanation | 16:40 |
jgriffith | dannywilson: sorry... I'm like deer in the headlights right now | 16:40 |
jgriffith | dannywilson: not exactly sure which part you are looking at; so the config file entries? No, but I'll work that out next | 16:40 |
dannywilson | jgriffith: no problem, yes the config file entries | 16:41 |
jgriffith | dannywilson: there's also the part about how to specify the optional secondary, I kinda need to play with that | 16:41 |
jgriffith | dannywilson: ahh... ok, yeah; so the doc I added it, but I'm going to go back to allowing multiples I think. | 16:41 |

*** bill_az has joined #openstack-cinder | 16:42 | |
dannywilson | jgriffith: sounds good, thanks | 16:42 |
xyang1 | aorourke_: It seems that a check is missing to prevent that. Let me think if there were any reason why this is allowed. By the way, a CG itself is not guaranteed to be consistent, only the Cgsnapshot is | 16:43 |

pv | hey i had a question | 21:45 |
pv | im testing my driver's attach/detach functionality and its an FC driver | 21:45 |
pv | my initialize_connection code works up to the point where it says it completed successfully from the volume manager | 21:45 |
pv | but my n-cpu log is giving me an error saying the attach failed because "no fc hosts could be found" | 21:45 |
pv | my machine is definitely hba enabled, and when i do a systool -c fc_host -v the wwn matches the one that the connector passes into initialize_connection | 21:46 |
pv | n-cpu log http://pastebin.com/wJHeaTsn | 21:47 |
pv | 2015-08-20 14:42:30.639 INFO cinder.volume.manager [req-0a07de9b-0110-49fa-9106-ed7dbae54e8c None] [volume-6415de2f-a2af-4ddb-a60a-b3a26c315bc9] Initialize volume connection completed successfully. | 21:47 |

jgriffith | xyang1: sure? | 22:00 |
xyang1 | jgriffith: So after failover is complete and volume is in available status, we can still use it as usual? | 22:01 |
jgriffith | xyang1: yes | 22:01 |
xyang1 | jgriffith: Ok | 22:01 |
jgriffith | xyang1: so the idea was to just update the model info as needed so it's somewhat seemless | 22:01 |
xyang1 | jgriffith: sure | 22:02 |
*** kjnelson has quit IRC | 22:02 | |
xyang1 | jgriffith: So if the host is changed, driver needs to return that info thru model update? | 22:03 |
kmartin | pv, is your FC SAN zoned correctly or are you using the FC Zone Manager? | 22:03 |
*** bapalm has joined #openstack-cinder | 22:03 | |
jgriffith | xyang1: Yes, so that would be something in the replication_updates data | 22:03 |
pv | also in https://github.com/openstack/os-brick/blob/master/os_brick/initiator/connector.py#L853 the requirements for FC in connection_properties say target_iqn, target_portal and target_lun | 22:03 |
jgriffith | xyang1: informs the manager that it needs to update something | 22:03 |
kmartin | pv, either way it sounds like a zoning problem | 22:03 |
pv | thats a typo right? | 22:04 |
xyang1 | jgriffith: Ok, thanks | 22:04 |
jgriffith | xyang1: sure | 22:04 |
pv | its zoned correctly, im not using zone manager currently | 22:04 |

jgriffith | dannywilson: ok, here's my plan | 23:37 |
*** p0rtal has quit IRC | 23:37 | |
dannywilson | jgriffith: all ears, or eyes I guess | 23:38 |
jgriffith | dannywilson: instead of trying to be clever and concisely combing managed and unmanaged config options under the same variable.. | 23:38 |
jgriffith | dannywilson: I have two config options: | 23:38 |
*** p0rtal_ has quit IRC | 23:38 | |
jgriffith | 1. managed_replication_devices = <backend-a>,<backend-b>..... | 23:38 |
jgriffith | 2. unmanaged_replication = <san_ip=1.1.1.1:san_login=admin:san_password=admin....>,<xxxxx> | 23:39 |
*** gouthamr has joined #openstack-cinder | 23:39 | |
jgriffith | dannywilson: so there's plenty of flexibility for everyone | 23:40 |
jgriffith | dannywilson: and you can provide multiple devices | 23:40 |
dannywilson | jgriffith: sounds good to me | 23:40 |
jgriffith | dannywilson: I then do a check when parsing config, and throw an error for invalid config if you configured both | 23:40 |
jgriffith | dannywilson: we can tackle dealing with both in M :) | 23:40 |
dannywilson | jgriffith: agreed | 23:41 |
jgriffith | dannywilson: I'll have a patch in a bit with those updates, as well as updates in the docs | 23:41 |
dannywilson | jgriffith: so base driver will make those lists available to derived drivers? | 23:41 |
dannywilson | jgriffith: excellent | 23:41 |
jgriffith | dannywilson: yes, I'm putting these in base-driver as we type :) | 23:42 |
jgriffith | dannywilson: the help is a bit wordy, but I'd rather that than the opposite I guess :) | 23:42 |
dannywilson | jgriffith: indeed | 23:42 |
jgriffith | dannywilson: I've been playing with different ways to delimit this.. maybe you have a preference? | 23:43 |
dannywilson | jgriffith: thanks very much, will be updating our implementation to match tomorrow morning probably | 23:43 |
dannywilson | jgriffith: not really, as long as it works ;) | 23:43 |
jgriffith | dannywilson: {san_ip=1.1.1.1:san_login=foomaster:san_password=4shnizzle},{san_ip=2.2.2.2:san_login=foomaster:san_password=4shnizzle} | 23:43 |
jgriffith | or | 23:44 |
jgriffith | {san_ip=1.1.1.1 san_login=foomaster san_password=4shnizzle},{san_ip=2.2.2.2 san_login=foomaster san_password=4shnizzle} | 23:44 |
jgriffith | ^^ spaces instead of ':' | 23:44 |
jgriffith | Or s/=/:/ with spaces as delimeters | 23:45 |
dannywilson | jgriffith: spaces are a little easier on my eyes in IRC anyway | 23:45 |
jgriffith | Or any of the above but drop the {} enclosures | 23:45 |
jgriffith | spaces it is then | 23:45 |
jgriffith | :) | 23:45 |
jgriffith | I'm not sure if I want to include the {}, they're just extra "things" to parse | 23:46 |
dannywilson | jgriffith: okay, and actually for our driver we don't need login/password but we use token based auth | 23:46 |
jgriffith | though it might make it more readable though | 23:46 |
dannywilson | jgriffith: yes, helps to separate them | 23:46 |
jgriffith | dannywilson: yeah, so the good thing is those keys=values can be whatever you want | 23:46 |
jgriffith | completely up to you | 23:46 |
