hemnajungleboyj: rosmaita, so FWIW, I just had another call with HPE about their CI14:19
hemnathey are actively working on it14:19
hemnathey are close to getting py37 working14:19
hemnabut are still running into issues14:19
hemnathey tried to upgrade the providers to ubuntu 16, but it didn't work14:19
hemnaso they are sticking with newton for now.14:19
hemnajust to get the py37 tests working14:20
rosmaitawhen you say "sticking with newton", what does that mean exactly?14:21
hemnaafter Train, they will look into upgrading to Zuul v3 etc14:21
jungleboyjhemna:  Thanks for the update.  Worried they will run into other issues with running such an old level, but ok.14:21
jungleboyjhemna:  Ah, ok ++14:21
hemnarosmaita: that's the old old way of doing CI with jenkins, etc14:21
hemnathe baremetal are providers14:22
hemnathat run devstack14:22
hemnathat stand up VMs that run the real tests14:22
hemnathose providers are running newton devstack14:22
hemnato stand up master devstack vms14:22
rosmaitathat's not complicated at all14:22
hemnathose run the real tests14:22
hemnayah, it's pain14:22
*** ociuhandu has quit IRC14:23
rosmaitaok, so the lowdown is that the actual tests are being run on master, so that's cool14:23
hemnathis is years old stuff14:23
hemnathey might get it working this weekend14:23
hemnaso, lets hold off on merging the patch for HPE until the deadline14:23
hemnaThey are all in India14:24
hemnaso, there is a timezone difference and why they aren't in irc much14:24
hemnaI told them to first contact us here, but also post to the mailing list on their status.14:24
rosmaitaok, great14:24
rosmaitawell even if the patch gets merged, it can still be reverted before the stable branch is cut14:25
hemnayah, that's what I told them too14:25
rosmaitamy point isn't that we necessarily *want* to merge it, my point is that they shouldn't quit if they don't get everything done by wednesday14:26
rosmaitagreat, thatnks for working with them on this14:26
hemnayah, that's what I told them.  That even if we miss the 12th, that the patch can get reverted, so keep working on it no matter what14:28
hemnaCI is such a PITA14:28

hemnahrmm, my cinder.conf doesn't have a port either15:53
hemnaso maybe keystone is down?15:53
Roamer`if it says "internal server error", my first thought would be to check the apache and keystone logs15:53
Roamer`yeah, it ought to be the apache logs, since keystone runs there15:54
hemnayah, looks like it errored out15:54

Roamer`virendra-sharma, if you want to run with Pyhton 3 (and, yeah, I guess you should want to), you need to set USE_PYTHON3=True and PYTHON3_VERSION=3.7 in the devstack localrc file16:12
Roamer`right, local.conf would work too, sorry, I'm already too much used to the zuulv3 settings :)16:13
Roamer`hemna, btw I updated with unit tests, oof, thanks!16:14
virendra-sharmaI have done those setting in local.conf, is that enough for pip to point 3.7 ?16:14
hemnaRoamer`: sweet16:14
hemnathanks for that16:14
hemnaI guess you probably should add a release note for it as well, since this enables multiattach16:15
Roamer`for a moment I wondered if the "No module named keystone" problem could be related to the python3-then-2-then-3-again issue, but, well, it would only matter if keystone.server.wsgi and bin/keystone-wsgi-public were installed by different Python modules, which seems unlikely (haven't checked though)16:17
Roamer`virendra-sharma, do you preserve the host for a while after a failed run? can you check what is the first line of the /usr/local/bin/keystone-wsgi-public file - is it #!/path/to/python3.7 or is it #!/path/to/python2.something?16:19
virendra-sharmayes, I noticed some of packages used pip2.716:19
virendra-sharmaI do have node with me on which devstack failed16:19
virendra-sharmait is "#!/usr/bin/python3.7"16:22
Roamer`ok, so it's not that, so I honestly have no idea what could lead to this file being present and keystone.server.wsgi not being found16:23
Roamer`I mean, this file ought to be installed by a "pip3.7 install keystone", which certainly ought to install the module, too16:24
Roamer`maybe ask in #openstack-keystone or #openstack-qa or something16:24

I was loading a lot of data unto it... and suddenly one of the volumes (where the ElasticSearch data was writing on) remunted as Read-only (Centos 7). I stop everything, umount the volume, fsck it, it repaired some journal stuff, re munted, start all over and as soon as I start ElasticSearch and the other nodes start se17:57

jbernardqqmber: there's a reasonable chance that it's not a bug in cinder, but that's probably the best place to work through it18:02
