abhishekkandreykurilin: ^^^^12:09
andreykurilinabhishekk: we do not use custom ci for checking glance scenarios. It is just regular infra ci. so to apply proposed change we need to modify devstack or project-config12:10
abhishekkyou can run rally scenarios in your local environment right?12:11
*** markvoelker has quit IRC12:13
andreykurilinyes, but I do not have a VM now to install rally with OpenStack12:13
abhishekkohhh12:13
abhishekkwe cannot propose patch as we can not determine the exact value for socket-timeout12:14
abhishekkI have tried it with 10GB only, not tested it for higher size because of limited resources :(12:15
*** bkopilov has joined #openstack-glance12:24
andreykurilinabhishekk: In gates the size of image is quite small, I think it is much smaller that 10gb12:25
andreykurilinbecause the whole hd is 10gb ))12:25
andreykurilinabhishekk: do you know, does it possible to propose a change to devstack and make a patch to rally project with depends-on to devstack change? will infra apply c change from devstack ?12:26
abhishekkandreykurilin: ok, but definitely this is the problem of uwsgi socket12:26
abhishekknot sure, ideally it should do12:27
andreykurilinabhishekk: I'm not saying that the problem in glance:) even more, I mentioned that all these years we did not have any problems with glance till now12:27
rosmaitaandreykurilin: yes, and we appreciate that12:28
rosmaitawe're just a little sensitive12:28
kairatabhishekk, will you able to create empty images?12:28
abhishekkwait, I am running rally and it is failing even with higher socket-timeout value12:28
rosmaitaabhishekk: ty for being on top of this12:28
abhishekkkairat: yest12:28
abhishekkrosmaita: no problem12:29
kairatso i mean only image upload request is failimn at the current moment12:29
kairati wondering if it is related to http-keepalive12:29
abhishekkkairat: no it is not creating empty image12:29
abhishekkhttp-keepalive is false in uwsgi12:30
andreykurilinrosmaita: everyone is sensitive about their project ;)12:30
kairatabhishekk, so any request fails with 502&12:30
kairat*502 error12:31
kairati am asking because when I tried to deploy glance under uwsgi  it was not supporting chunked requests12:32
*** markvoelker has joined #openstack-glance12:32
abhishekksorry, my reply might be late as I am travelling to home now12:32
kairatnp12:32
abhishekkit does not create zero size image-file when it fails with 502 error12:35
*** abhishekk has quit IRC12:35
kairatneed to know if you able glance image-create without file12:36

rosmaitahello everyone14:50
efriedrosmaita https://etherpad.openstack.org/p/glance-store-priority-reviews-pike14:50
rosmaitalet's have an impromptu glance_store prioritization14:50
rosmaitausing the etherpad efried has so kindly created for us14:50
efriedPasted in that link that IRC split up three times.14:51
efriedCan use it as a start.14:51
efriedLooks like there's really not that many.14:52
efriedShould be able to knock out those "Needs final +2" pretty quick, nah?14:52
rosmaitasorry, was looking14:54
rosmaitayes, that';s a good place to start14:54
*** efried is now known as efried_bbiab15:00
rosmaitajokke_: how do you feel about https://review.openstack.org/#/c/430641/ ?15:00
rosmaitagone through 31 patch sets since feb 815:00

jokke_looking15:02
rosmaitayou don't have to assess patch quality atm, just whether the topic is a good one to include15:02
jokke_yes I think that would be super helpful to include ... also I have to disagree smcginnis "hole" is the only well known term for those holes in sparse files I've ever stumbled upon to in my stroage career so I would not hold it up for using it ... I just haven't had time to actually test that it works15:05
rosmaitaok, cool15:05
rosmaitai think fei long is still ceph driver maintainer, so i will shoot him an email to look too15:05
jokke_I'll ping our ceph guys if someone would have time to have a look on that15:07
smcginnisjokke_: No worries, I've certainly spent more time on the block side than file. Just hadn't heard that commonly used over the last 15 years in storage.15:08
rosmaitawhat's the policy about backports? do we need to worry about that now? asking about https://review.openstack.org/#/c/410547/15:08
*** e0ne has joined #openstack-glance15:09
*** lucasxu has quit IRC15:09
jokke_rosmaita: glance_store follows normal stable policy15:10
rosmaitaso would now be a good time to backport a fix, or wait?15:11
jokke_rosmaita: I'm not 100% sure if ending up with bigger volume than requested is critical enough to backport to newton15:12
*** abhishek_k has joined #openstack-glance15:12
rosmaitagood enough, let's not worry about it15:12
jokke_I'd focus atm. to get the Pike release together and look into other backport after that15:12
rosmaitasean raises a good point on this one: https://review.openstack.org/#/c/448316/115:13
jokke_we can have a look of backports and request stable releases the week after15:13
rosmaitanamely, we need the patch that actually removes the deprecated options15:13
rosmaitai'll pick up this patch and add the option removal to it15:13
rosmaitawill also look over whether there's anything else deprecated that's supposed to go in this cycle15:14

abhishek_krosmaita, jokke_: ran couple of scenarios with higher socket-timeout value, http://paste.openstack.org/show/615295/16:36
jokke_abhishek_k: so it really looks like it's just socket timeout issue?16:37
abhishek_ki will try to configure uswgi logs and find out if I can get any helpful logs from uswgi side, http://uwsgi-docs.readthedocs.io/en/latest/Logging.html16:37
abhishek_kjokke_: yes16:38

rosmaitayour results are interesting, the concurrent uploads seem to indicate that its not a data saturation problem, probably is just a timeout16:42
