hemnathe other is for alternative paths to the same volume16:51
jgriffithhehe... but that's my point16:51
jgriffiththey "could" very easily and probably "should" IMHO be the same thing16:52
jgriffithalternative path, vs multi path16:52
jgriffithseems like a distinction without much of a difference16:52
hemnaso there needs to be additional data then passed back to brick/nova to tell it what it needs to do then.16:52
hemnaif it's trying to do a multipath attach vs. a single attach is different16:52
jgriffithhemna: sure16:52
hemnajust because you have a list of target_portals doesn't mean you want multipath16:53
hemnaso I guess that's why there was a distinction16:53
jgriffithhemna: understood16:53
jgriffithhemna: but why not just use the same data structure and a separate 'thing' to specify whihc you want?16:53
hemnayah I suppose that would be ok16:53
jgriffithhemna: if you look at the DS's they seem to duplicate an awful lot of code16:54

jungleboyjSeems sensible to me.16:54
jgriffithhemna: and like i said in my review, I really don't like the "if this format, else that format" thing16:54
jgriffithThat's a compatability/support nightmare waiting to happen IMHO16:54
hemnaok I'm cool with that16:54
jgriffithhemna: The only other question is should they both be changed :)16:55
jgriffithhemna: to something that plugs seemlessly into the existing model16:55
nikesh_vedamshi16:55
jgriffithhemna: you're way more involved in this than I so I'll defer to you16:55
hemnaI like target_portals16:55
jgriffithhemna: yeah... I do too16:56
jgriffithhemna: but that means we're "stuck" until a change is made on the Nova side16:56
hemnaand an additional flag telling brick/nova what to do with them.  Multipath: True16:56
jgriffithno?16:56
hemnaif that's not there, then it's considered alternative portals16:56
nikesh_vedamsi am trying to run cinder tests under /opt/stack/cinder but getting errors http://paste.openstack.org/show/180654/16:56
hemnajgriffith, yah I think so16:56
nikesh_vedamsis any facing this issue,i am using ubuntu 14.0416:57
jgriffithnikesh_vedams: try deleting/rebuilding your venv16:57
jgriffithnikesh_vedams: it looks to me like youre venv never actually built correctly16:57
jgriffithhemna: so that's up to you guys I suppose, but I just thought we could make the DS in such a way that the existing code would all still "just work"16:58
nikesh_vedamsokk let me check16:58
hemnajgriffith, I don't think the nova side has landed16:58
smcginnisnikesh_vedams: ./run_test.sh -f16:58
jgriffithhemna: no it hasn't... and it's not going to based on the looks of it16:58
hemnaI think they were waiting on brick16:58
hemna:)16:58
hemnaso that part is good16:58
jgriffithhemna: hence my concern for having this stuff half in/ half out16:58
hemnaso we can fix this here in K before it's release16:59

jgriffithThat's what I'm thinking... if you and Tomoki agree with me16:59
hemnayah I do16:59
jgriffithcoolness16:59
hemnafwiw, the spec was approved though.  and you did +2 it :P17:00
xyang1jgriffith: hemna there are already a couple of drivers made changes based on the multipath enhancement17:00
jgriffithhemna: sure17:00
hemnaanyway17:00
hemnaxyang1, which ?17:00
jgriffithhemna: but also TBF that was two specs17:01
xyang1jgriffith: hemna emc vnx and dell.  It is backward compatible17:01
jgriffithhemna: and I'm more concerned with impl than with the concept17:01
xyang1So it works with current nova code too17:01
hemnasure17:01
hemnaxyang1, well, the current nova code ignores the new entries17:01
hemnatarget_portals, target_alterative_portals17:01
xyang1I know17:01
hemnaso yes, it 'works'17:01
xyang1I mean the driver still keeps the existing behavior17:02
xyang1If nova side gets in, it will work with the new cide17:02
xyang1Code17:02
jgriffithhemna: xyang1 so the one wth the portal lists etc that already landed I didn't really have an issue with17:02
hemnaI don't think we want the nova side to land though17:02
jgriffithxyang1: hemna the concern for me was when I saw this one: https://review.openstack.org/#/c/140877/17:03
jgriffithxyang1: hemna that IMO could be consolidated17:03

xyang1Sorry, wrong one17:06
jgriffith:)17:06
xyang1:)17:06
tsekiyamahmm, using target_portals/iqns/luns even when multipath is False ?17:07
jgriffithI've had that thrown in my face way too many times the past couple monts17:07
jgriffithtsekiyama: oh... hellooooo!17:07
jgriffith:)17:07
nikesh_vedamsjgriffith : thanks17:07
jgriffithfor some reason I thought you'd be in a "sleeping" Time zone17:07
dannywil_ls17:07
tsekiyamajgriffith: :)17:08
hemnaxyang1, so it looks like the emc code could be changed to simply return multipath: True when it populates target_portals.17:08
jgriffithtsekiyama: so did you see my thoughts on the review?  And the conversation with hemna ?17:08
hemnaxyang1, that patch doesn't include support for target_alternative_portals17:08
tsekiyamaWhen multipath = True, it omits target_portal/iqn/lun and add target_portals/iqns/luns. it is ok because multipath=True means the connector knows how to deal with new multipath structure.17:08
tsekiyamaBut when mutlipath = False, we need to think about backward compatibility ..17:08
xyang1hemna: That is right. We don't support it17:08
hemnaxyang1, so the EMC patch is ok.17:08
*** alecv has quit IRC17:08
xyang1hemna: Ok. Good17:09
tsekiyamaso we can't omit target_poratl/iqn/lun17:09
jgriffithtsekiyama: yeah, but I'm wondering if we could just consolidate on a single supported data-structure with optional keys for the multi-path and fail over17:09
hemnatsekiyama, so the change we are thinking of here is to eliminate the target_alternative_portals17:09
*** Miouge has joined #openstack-cinder17:09
*** Saba has joined #openstack-cinder17:09
hemnaand simply reuse target_portals17:09
hemnaas a list17:09
hemnaand the driver says, multipath: True or False17:09
jgriffithtsekiyama: yeah... kinda what hemna said :)17:09
*** Saba is now known as Guest8785817:09
hemnaif the driver returns multipath: False,   then target_portals is the same logic as target_alternative_portals was meant to be.17:10
jgriffithtsekiyama: my main point was not proliferating data structures, but using them more intelligently17:10
Guest87858Hi , I am wondering if get_volume_stats is exposed as metric in cinder  for reading free capacity17:10
hemnajust a list to iterate over to try and get a connection to work at all17:10

jgriffithGuest87858: nope17:10
Guest87858Hi , I am wondering if get_volume_stats is exposed as metric in cinder  for reading free capacity17:10
jgriffithGuest87858: and again... "nope" :)17:10
hemna:)17:10
jgriffithxyang1: I think it's ok if we need to fix drivers that implemented it already17:11
jgriffithxyang1: it's all the same 'stuff' just presented slightly differently17:11
tsekiyamahemna: jgriffith: just concidering we should have both 'target_portals' and 'target_portal' when multipath=False, for old nova17:11
xyang1jgriffith: That's fine.  We just need to know17:11
smcginnis+1 on consolidating structures. That seems simpler IMO.17:11
hemnatsekiyama, yah17:11

jgriffithtsekiyama: if you look at my comments in the review17:12

jgriffithhemna: xyang1 tsekiyama Just some ideas17:14
jgriffithGuest87858: no worries17:15

e0nejungleboyj: few questions from me20:13
openstackgerritDanny Wilson proposed openstack/cinder: Over subscription for Pure Storage iSCSI driver.  https://review.openstack.org/15768120:14
e0nejungleboyj: did you se my comment for https://review.openstack.org/#/c/149446/? not sure now is the best way to do20:14
e0neit's about volume copy bandwidth20:14
*** marcusvrn has quit IRC20:15
jungleboyje0ne: Looking.20:16
e0nejungleboyj: thank you20:16
jungleboyje0ne: Oh, you think it should be renamed 'throttling' so you don't have to do 'import throttle as throttling'?20:17
e0nejungleboyj: yes, because it is used as 'import throttle as throttling' everywhere20:18
jungleboyjI guess I can see that argument.20:20
e0nei won't -1 it if you thinl it's not important20:21
jungleboyjI just updated and asked Tomoki's input.  See what they say.20:22
e0nethanks20:22
jungleboyje0ne: No problem.  Thanks for looking through the incubator patches.  I am getting close to getting the scheduler patch fixed up.  That that point I can do the rest of the cleanup in cinder/openstack/common and then get the move to oslo.log done.20:23
jungleboyje0ne: Will be excited to have all this done.20:24

jungleboyj:-)  Yeah, I hope we can get this wrapped up this week.20:27
jungleboyjpatrickeast: I owe you one.  I got Edwin to dig into that issue with the flashsystem CI and he discovered he had a downlevel version of the CI code that wasn't properly pulling the patches down.20:28

smcginnisUnless I'm doing something different here.21:59
*** annashen has joined #openstack-cinder21:59
xyang1smcginnis: I think it has to do with the exception itself22:00

xyang1https://review.openstack.org/#/c/143162/22:03
smcginnisanish: That looks like what I would expect.22:03
smcginnisThough not sure why it would be different between debug and info.22:04
smcginnisI would think either the logger handles unicode or it doesn't.22:04
*** Apoorva has quit IRC22:06
anisherm, the documentation seems way off. Uses % in logging. From a review that I cannot remember, someone mentioned that % + dict can have issues in logging as well22:06
smcginnisLine 325 would support anish's understanding, at least for info level: https://review.openstack.org/#/c/143162/3/cinder/brick/iscsi/iscsi.py22:06
anishhopefully same for all non-debug levels22:08
smcginnisanish: It does appear so: http://paste.openstack.org/show/180820/22:09
smcginnisThe i18m guidelines do state: "Whenever possible translation should not be forced by use of str(), unicode(), or six.text_type() on a message being used with a format string."22:09
anishsmcginnis++ thank you for the research22:10

*** JayJ has quit IRC22:23
*** JayJ has joined #openstack-cinder22:24
smcginnisxyang1: OK, in that patch exceptions are just being passed in to LOG.error, but six.text_type(e) is used for debug.22:25
smcginnisBut that actually didn't change with his changes.22:25
smcginnisThose appear to only have been changed to go from % to ,22:26

smcginnisxyang1: The logging of "out" and "err" from the _run() command?22:29
xyang1Yes22:29
*** harlowja has joined #openstack-cinder22:30
*** ebalduf has quit IRC22:30
smcginnisThat doesn't look directly related. At least from the commit message.22:30
smcginnisCommit message actually gives "LOG.error("%s" % e)" as the offending format.22:30
smcginnisNothing about using six.text_type().22:31
smcginnisSo I think it probably comes down to doing LOG.debug('Test: %s', e) vs LOG.debug('Test: %s' % e)22:31
smcginnisWith the first being the correct way.22:31
smcginnisIt appears (and I would expect) the logger to handle it correctly.22:32
