openstackgerritGhanshyam Mann proposed openstack/nova master: Workaround for pdf-docs build failing with sphinx 3.1.0  https://review.opendev.org/73527903:22
gmannmelwitt: stephenfin gibi dansmith ^^ this is workaround on gate fix for pdf-docs build failing. We are hitting the TeX memory issue here due to our large sample files.03:31
gmanni am not sure how to fix that as sample files is too large to include. It started failing with new Sphinx 3.1.0 which is also mystery as i cannot find any related change in that.03:32
gmannworkaround passing on gate. I am going away as my memory also exhausted :) on this pdf debugging where no relevant log on failure.03:35
gmanncan we make pdf build as non-failing ?03:36

openstackgerritBalazs Gibizer proposed openstack/nova master: Workaround for pdf-docs build failing with sphinx 3.1.0  https://review.opendev.org/73527911:27

*** ociuhandu_ has joined #openstack-nova12:41
gmanngibi: found the real issue on this. we are expanding the sample policy file in two places and that is why two times giant policy file inclusion end up excaussting memory - 1. https://github.com/openstack/nova/blob/a9e0b0573da65074db686ceb0c5cc000ec7110f1/doc/source/configuration/sample-policy.rst 2. https://github.com/openstack/nova/blob/master/doc/source/admin/configuration/samples/policy.yaml.rst12:43
gmannwe should ref the second one to first location and then it solve the memory issue.12:43
gmanni thought it was just one place and still eating up all memory.12:44
gmannand pdf doc also should be fine as it can refer the another section in same pdf doc.12:47
*** jawad_axd has quit IRC12:53
gibigmann: cool. feel free to propose the real solution12:55
gmanni am testing on pdf doc also so that we do not endup web link there and then i will update12:56
gibiyeah, I saw that many of our pdf links are weblinks. But I think this is a generic problem12:59
*** mriedem has joined #openstack-nova13:06
*** lvdombrkr has joined #openstack-nova13:11
lvdombrkrHello guys. changing root password with nova set-password and nova get-password is deprecated now?13:13
gmanngibi: you mean external links right not nova doc link right?13:14
*** lpetrut has joined #openstack-nova13:15
gmannlvdombrkr: no, its not deprecated.13:19
gmannany warning you are getting for deprecation ?13:20
lvdombrkrgmann: no no i heard somewhere that its depricated. can i pass by this metod password to instance during booting?13:23
gmannlvdombrkr: yeah you can pass with adminPass field13:25
gmann--admin-pass for CLI13:26
lvdombrkrgmann: and then this pass will be stored on metadata as plaintext?13:26
*** ravsingh has quit IRC13:29
*** ociuhandu_ has quit IRC13:31
*** ttsiouts has quit IRC13:31
gibigmann: looked deeper, most of the nova doc links are local in the pdf but some (e.g. on  page 125) are web links even if it could be a pdf local link13:32
*** ociuhandu has joined #openstack-nova13:33
zigogibi: gmann: Do you know the answer about OS_NOVA_DISABLE_EVENTLET_PATCHING=yes? Is it fine to run nova-api with it? If so, I'll hard-wire it in the nova package in Debian, as it looked working better for us. I really would love to get upstream opinion here...13:33
zigoI don't know the code well enough to tell what this implies.13:33
gibizigo: based on the code comment in https://github.com/openstack/nova/blob/a9e0b0573da65074db686ceb0c5cc000ec7110f1/nova/monkey_patch.py#L95 I don't think it is intended the services13:35
zigoRight.13:36
zigoThat's kind of what I thought, though my colleague insisted...13:36
gibizigo: also I think the nova-api service uses eventlet for parallel querying multiple cells13:37

lvdombrkrgmann : openstack server create: error: unrecognized arguments: --admin-pass13:40
*** vishalmanchanda has joined #openstack-nova13:41
gmannlvdombrkr: you are using osc or novaclient? for nova client --admin-pass works but i cannot see that in osc which might be missing and not up to date13:43
gmannand password in get is always encrypted not plaintext.13:43
*** ravsingh has joined #openstack-nova13:45
gmannand clear password does not actually clear the server password but only remove it from metadata13:45
gmanngibi: i cannot see page 125 with link? or you mean some other page?13:47
lvdombrkrgmann: i need to remove ir from metadata by myself?13:48
gmannI mean if you want then there is API for that.13:49
gmannotherwise in metadata it is in encrypted form.13:49
gibigmann: https://ibb.co/ftWttM213:50
gmanngibi: ohk, that is 114 in this - https://docs.openstack.org//nova/latest/doc-nova.pdf13:51
gmannyeah those  should be fixed. I will do it but later13:51
gibigmann: yeah this is from the pdf workaround patch so I guess the difference in numbering is due to the remove policy sample13:52
gibigmann: sure, no rush fixing these13:52
gmanni see13:52
lvdombrkrgmann: to pass password by --admin-pass in nova.conf inject_password=true13:54
lvdombrkr should be set?13:54
lvdombrkror its not related?13:54
lvdombrkrand are two saparete ways13:54
gibilvdombrkr: did you tried the nova CLI I'm not sure openstack CLI has the --admin-pass flag implemented13:56
gmannyeah osc does not have13:56
gibilvdombrkr: and I also think you need inject_password=true in the nova.conf on the compute side13:58
gibimaybe even inject_partition = -113:58
gibiand also python-guestfs package installed on the compute node13:59
lvdombrkrgibi: inject_password=true inject_partition = -1 not working with python3 thats why im looking other way to inject password13:59
frickleropenstack server set --root-password exists, but no get-password seemingly13:59
lvdombrkrgibi : https://review.opendev.org/#/c/733982/14:00
lvdombrkrfrickler: yes yes but still need this patch   https://review.opendev.org/#/c/733982/ correct?14:01
gmannhumm, and we do not test that?14:01
fricklergmann: doesn't look like it, unit testing is all mocked, no real functional test I've found14:02
gibilvdombrkr: thanks for the context, I think I was able to reproduce your bug14:02
fricklerlvdombrkr: the set-pw seems to try to use QEMU guest agent instead, when I try it I get: QEMU guest agent is not enabled (HTTP 409)14:03
