#openstack-nova - 2017-06-21
15:13:59 mriedem so the thinking is, the compute node resource provider has a trait for that capability flag, and if the server create request has tagged nics/bdms, we put a required trait in the request spec for the scheduler to use fo filtering hosts
15:14:03 jaypipes mriedem: that seems like a fine one to me, sure
15:14:21 mriedem ok coll
15:14:23 mriedem *cool even
15:32:07 efried sfinucan Looks like actdiag will generate SVG with the -T option. Guessing if it's not there already, this would have to be enabled via the docs builder code.
15:32:37 sfinucan efried: I'm using SVG atm (which is why you can copy paste the text)
15:33:01 efried sfinucan Oh, okay. I thought I saw an email that said you were frustrated by that.
15:33:29 sfinucan aha - no, sorry, I should have said I'd managed to figure that one out
15:33:37 sfinucan but not the other one. My mistake :)
15:33:50 sfinucan Though I have figured out the other one now, give or take
15:34:07 efried sfinucan Oh, was about to propose a patch for that.
15:34:32 efried My current crude workaround is jamming \n in the strings by trial/error.
15:34:40 sfinucan efried: Do anyway. Mine is kind of hacky (monkey patching stuff)
15:34:47 sfinucan ...though maybe not as hacky as yours :D
15:35:09 efried I'm looking to see if there's block size and/or autowrap options in the tooling. But I assume you've already done that.
15:46:44 openstackgerrit Markus Zoeller (markus_z) proposed openstack/nova master: docs: Explain the flow of the "serial console" feature https://review.openstack.org/476188
15:48:30 openstackgerrit Matt Riedemann proposed openstack/nova master: Explain why API services are filtered out of GET /os-services https://review.openstack.org/476189
15:49:37 mgagne mriedem: what kind of exception do you suggest it raises? https://review.openstack.org/#/c/454322/18/nova/virt/libvirt/driver.py@1420
15:51:56 efried sfinucan Looks like the best we can do (without hacking the source) is specify box height/width and sprinkle in newlines.
15:53:26 mriedem mgagne: the volume driver's default implementation for the extend_volume method could be just to raise NotImplementedError
15:53:38 sfinucan efried: Hmm, I wonder if hacking the source is such a bad thing though?
15:53:48 sfinucan I mean, IMO the current implementation is broken
15:54:00 mriedem mgagne: the libvirt driver code would have to handle that and translate it to some NovaException, like ExtendVolumeNotSupported or something
15:54:03 mgagne mriedem: so just reraise the NotImplementedError exception?
15:54:12 mgagne ok, that was my question
15:54:16 melwitt dansmith: +1 to skipping the cells meeting today
15:54:51 mgagne there are 2 things: virt might not support extend volume. volume driver within virt driver might not support extend volume. we need to handle both cases. first can be handled by capabilities. I'm not sure about the second one.
15:55:05 efried sfinucan I don't disagree. But where are you planning to hack?
15:55:19 mgagne so you suggest we reuse ExtendVolumeNotSupported if volume driver does not support extend volume?
15:55:21 mriedem mgagne: related comment here https://review.openstack.org/#/c/454322/18/nova/compute/manager.py@6891
15:55:31 sfinucan efried: https://review.openstack.org/476159
15:56:05 mgagne yes, handled that part, I'm not sure about the volume driver as it was not explicitly mentionned. will use the same exception then
15:56:43 efried sfinucan Yeah, that'd do it... partway. What about automatically adjusting the box size, though? With just this, you're going to get cut off.
15:57:01 mriedem mgagne: we could use different exceptions if we want, like you could raise ExtendVolumeNotSupported for the capabilities check, and subclass that with an ExtendVolumeNotSupportedForVolumeType exception if the volume driver doesn't support it - with that one having the type in the exception message
15:57:10 mriedem mgagne: i don't think it makes a ton of difference though
15:57:22 mgagne ok, will use ExtendVolumeNotSupported as suggested
15:57:29 mriedem the difference in error message that goes into the fault could be useful for an operator
15:57:56 mriedem but you tell me :) you're the one deploying this
15:58:16 sfinucan efried: You mean make all boxes bigger?
15:58:27 sfinucan I was trying to avoid that to stop stuff going off screen
15:58:30 mgagne haha, I have a totally different implementation and we fully support the feature so this code path is never used =)
15:58:45 efried sfinucan Well, not necessarily, though that would be easiest (changing the default box height).
15:59:09 efried sfinucan I was talking about scaling the box size dynamically according to font face/size + number of lines after your autowrap.
16:00:38 efried sfinucan ...which sounds pretty difficult to me.
16:01:02 sfinucan efried: That depends on how that tool is implemented
16:01:14 sfinucan efried: If they wrap text, then generate the box, it should be fine
16:01:41 sfinucan If the other way around, it might be tough/impossible as you'd need to resize an existing 'rect' and move anything below it too
16:01:50 efried sfinucan Still not sure how you would account for font face
16:02:27 efried sfinucan Oh, I guess it has a "measuring" facility built in.
16:02:29 efried Which makes sense.
16:02:46 sfinucan Yeah, it does that for us
16:03:27 sfinucan It's actually a surprisingly robust, well-tests bit of code, IMO
16:03:37 openstackgerrit Ildiko Vancsa proposed openstack/nova master: Add Cinder v3 detach to swap_volume https://review.openstack.org/456971
16:06:57 openstackgerrit melanie witt proposed openstack/nova master: Add get_count_by_vm_state() to InstanceList object https://review.openstack.org/446244

16:07:10 openstackgerrit melanie witt proposed openstack/nova master: Add online migration to move quotas to API database https://review.openstack.org/410946
16:09:35 sfinucan efried: I'll take another look-see and see if we can stop it truncating characters
16:09:58 openstackgerrit Eric Fried proposed openstack/nova master: Add formatting to scheduling activity diagram https://review.openstack.org/476204
16:09:59 efried sfinucan ^^ Manual formatting; feel free to squash it into yours if you like.
16:10:06 sfinucan Ta :)
16:12:56 cfriesen_ mriedem: for "nova show --minimal" do we want to keep the pre-2.47 "flavor" field name, or change it to "flavor:original_name" to reflect what's in the REST API response?
16:13:31 mriedem cfriesen_: i'd keep it the same
16:13:37 mriedem in the --minimal case
16:13:38 mriedem since it's a single field
16:13:45 mriedem the namespace flavor: is for the multi-field show details
16:14:15 efried sdague mriedem We had an unfortunate miscue last week; events conspired to blow up the PowerVM driver. Fix is here https://review.openstack.org/#/c/475926/ - in-house +1s and passing our CI :)
16:14:54 mriedem ha, isn't that the exact same change where i said the ci was failing
16:14:55 mriedem ?
16:15:09 mriedem "The CI failed but I guess that's an unrelated known issue so this seems fine."
16:15:27 efried mriedem Yes, precisely; the CI was indeed failing for totally unrelated reasons.
16:15:46 efried ...but by the time we got around those, that guy had merged, and broke it further down the line.
16:17:10 mriedem ok +2
16:17:17 efried mriedem Thanks
16:22:14 efried sfinucan Note the last box in the Scheduler lane is truncated: http://docs-draft.openstack.org/59/476159/1/check/gate-nova-docs-ubuntu-xenial/bf9b0cb//doc/build/html/scheduling.html?highlight=scheduling
16:30:03 mriedem gibi_: going to probably want your input on this one https://review.openstack.org/#/c/403568/
16:30:43 mriedem gibi_: re: the question about whether or not we should or need to provide the network info for the instance in the instance.shutdown.end notification
16:30:52 mriedem since at that point it's really already deallocated
16:31:08 mriedem you would have it in the instance.shutdown.start notification
16:31:21 mriedem so maybe this is really just fixing the instance.shutdown.end notification to be accurate
16:32:21 kfox1111 anyone know the status of virtfs integration?
16:32:45 mriedem kfox1111: no status?
16:33:05 kfox1111 not implemnted yet? :/
16:33:11 mriedem as in,
16:33:16 mriedem no one is working on that
16:33:23 kfox1111 bummer. k.
16:33:31 mriedem i vaguely remember manila folks talking about something similar maybe pre-atx summit?
16:33:57 kfox1111 yeah. it handles the manilla case well.
16:34:09 kfox1111 also hpc/htc on nova.
16:34:29 mriedem https://review.openstack.org/#/c/310050
16:35:08 mriedem kfox1111: ^ is what you want
16:35:18 mriedem or as close as virtfs has gotten to nova land
16:35:40 kfox1111 yeah something like that.
16:35:43 kfox1111 thanks for the link.
16:39:25 sfinucan efried: Yeah, saw that. Wasn't sure if/how I could fix it
16:39:42 sfinucan Maybe your patch addresses it - I haven't checked yet
16:40:06 efried sfinucan Yes, mine does address it, but manually by setting box heights. The other option is as discussed above, adding an autosize facility.
