nwonknui'm fairly certain i don't even need this package, but it's a pain to figure out where this requirement for this package comes from (from what I've gathered, it's a "wheels" image being built linked to this image https://hub.docker.com/r/loci/requirements/tags/)10:12

*** alexchadin has quit IRC14:03
nwonknui actually managed to work around it by modifying the docker-compose file to use the loci/cinder:master-debian image, rather than one I build myself14:03
nwonknui think there is some issue with the loci build of cinder/requirements14:04
nwonknubecause i did the steps from the dockerfile manually, and ended up with the same results14:05

jgriffithnwonknu: I guess the bottom line is "is it workign for you now"?14:07
nwonknusorry i'll take a few steps back :)14:08
nwonknumy goal is to get cinder running standalone14:08
nwonknui've been looking at blockbox mostly14:08
nwonknuwhich i believe is your work14:08
jgriffithmyself and others14:08
nwonknuand so i am unable to build the cinder base image using the instructions here: https://github.com/openstack/cinder/tree/master/contrib/block-box14:09
*** moshele has joined #openstack-cinder14:09
jgriffithOH.. hmmm14:09
nwonknubut it doesn't seem to be related to blockbox, rather to LOCI14:09
nwonknusince the instructions here: https://github.com/openstack/loci end up with the same results14:09
jgriffithwhat version of Docker do you have?14:10
nwonknuand so my "solution" right now is not to use the self-built "debian-cinder" image referred to here https://github.com/openstack/cinder/blob/master/contrib/block-box/docker-compose.yml, but rather use a reference to loci/cinder:master-debian which is an image hosted on the dockerhub registry14:10
nwonknuDocker version 18.03.0-ce, build 0520e2430214:10
nwonknui don't think its a docker issue though, did you see the pastebin i sent earlier?14:11
jgriffithI'm running make now with the defaults, see what happens14:11
nwonknuit's a problem with a pip install of one of the requirements14:11
jgriffithnwonknu: nah, I couldn't find the scrollback; sorry14:11
nwonknuNo matching distribution found for enum-compat (from eventlet===0.20.0->-c /tmp/wheels/upper-constraints.txt (line 135))14:12
nwonknuand trying to edit these requirements files manually is not exactly an option as they are generated on-the-fly from what i've seen14:12
jgriffithand there I hit it14:12
nwonknuk, good i'm not doing anything stupid then ;)14:13
jgriffithnever, when it comes to anything that I have worked on you're most likely never doing anything stupid :)14:13
*** moshele has quit IRC14:14
jungleboyjHe he he.14:16
nwonknui'm happy this thing exists at all, or it would be a lot more work for me to get cinder up and running standalone, so i'm grateful for the work you did =)14:17
jgriffithnwonknu: I'm glad to hear it's useful for some14:18
jgriffithI was testing it pretty regularly and it was solid so I got complacent I guess :)14:18
nwonknuthe opensds guys are using it too, in case you didn't know14:18
jgriffithOh yeah!14:18
jgriffithI mean "Yay!"14:18
*** moshele has joined #openstack-cinder14:19
jgriffithOh Excellent!14:19
jungleboyjjgriffith:  Yeah, I have been working with OpenSDS and they are all about the standalone support.14:19
jgriffithI need to check in with portdirect one of these days and see where we're at with helm charts14:20
jgriffithnwonknu: so it looks like our req file might be jacked (as you already discovered) on the loci side14:20
jgriffithI'll poke around and see what I can find there14:21
jgriffithI know wheels are better to use, but they're a PITA sometimes14:22

dhellmannsmcginnis , eharney : I don't know off the top of my head what might break if we start deleting lots of release notes. It may be fine. What is the motivation for removing them?16:03
smcginnisdhellmann: eharney was the one I mentioned trying to enforce yamllint.16:04
smcginnisdhellmann: So we have a bunch of files with issues.16:04
smcginnisdhellmann: And easiest would probably be to just get rid of the old ones.16:04
smcginnisdhellmann: Less files in the directory too.16:04
dhellmannthe only thing I could think it would break is the ability to present a full history of the master branch16:06
dhellmannor any later branches, actually16:06
dhellmannalthough that's not likely a huge concern, given the way we publish them16:06
smcginnisDo we do that anywhere? My understanding was the current release note output all gets pulled out of git history.16:07
dhellmannit does, but if the files are deleted in the branch then they're skipped16:07
dhellmannso if you delete the history now, the stable/rocky branch won't have it16:07
smcginnisBut if we delete say a Queens release note, then that's fine?16:08
dhellmannwhich is fine if you only want stable/rocky to be able to report about notes added in that branch, which is basically what we do16:08
dhellmann*in that series16:08
dhellmannso I think it's probably fine, but it isn't designed to work that way so I'm not sure16:09
smcginnisdhellmann: Not sure if I really following what you said there about stable/rocky.16:09
smcginnisdhellmann: That's only if we delete rocky release notes before creating the stable/rocky branch?16:10
dhellmannif you delete a file that exists in the history of stable/queens from master then reno will see that delete event and skip the file when producing the history of stable/rocky16:10
smcginnisdhellmann: So theoretically, if we do the first thing after RC cut to delete old release notes, we would be fine with how we publish things?16:10
smcginnisdhellmann: Oh, OK. Then that's an issue I think.16:11
dhellmannso if you ever wanted to get all of the notes in the history of stable/rocky all the way back to the beginning of time, you wouldn't be able to do that16:11
smcginnisdhellmann: OK, thanks. Sounds like we probably shouldn't go that route then.16:11
dhellmannthe file *would* still show up in the history of stable/queens so you would get the note there16:11
smcginnisdhellmann: Each time I think I understand I realize I don't. :)16:12
smcginnisdhellmann: So if we deleted a note from queens from master right now, would our published release notes still show that in the queens notes?16:13
dhellmannyou're thinking of versions as points in time, but they're smears across the timeline16:13
smcginnisOK, then it does behave the way we would want it to.16:13
dhellmannwhen reno looks at the history of queens, it starts at the end of that branch and works backwards, so it would not see something that happened in master after the branch was created16:14
smcginnisAnd it would reduce the risk that someone would update a note in master to fix an old note issue.16:14
smcginnisdhellmann: OK, that's what I thought.16:14
dhellmannso as long as it's ok for branches starting with stable/rocky to not have that full history, then you're probably safe16:14
dhellmannand the way we publish our release notes, it is probably OK16:15
smcginnisOK, great. Thanks dhellmann16:15

eharneysmcginnis: so i did find a reason that this matters, actually16:18
eharneysmcginnis: look at the first line under "Bug fixes" here: https://docs.openstack.org/releasenotes/cinder/queens.html16:18
eharneyand compare to https://review.openstack.org/#/c/566675/1/releasenotes/notes/bug-1560867-support-nova-specific-image-7yt6fd1173c4e3wd.yaml16:18

throwsb1jungleboyj: hey, wonder if you have a few minutes to maybe shed some light on what looks to be storage timeouts.17:53
jgriffithnwonknu: Sam helped with figuring out what's up with the blockbox builds17:53
jgriffiththere's a dep on enum-compat that needs to be built and hasn't made it through the process yet17:54
jgriffithand we use no-build in the requirements install17:54
throwsb1On a fresh deploy with OSA, I was not able to provision storage.  Was getting timeout errors in UI.  On recommendation, I added the following to nova compute block_device_allocate_retries = 300 block_device_allocate_retries_interval = 12017:54
throwsb1I was good on provisioning a total of 6 vm17:55
jgriffithSo you can work around this by building a base container `--build-arg PIP_PACKAGES="enum-compat"` and then modifying the build process in the Makefile to build from that base image17:55
jgriffithOr... just keep using the published image for now and wait a bit for the changes to propogate17:55
throwsb16 vms, 3 per storage node.  then I would just get the same time out message after that.  The storage is LVM with SAN, multipath on the backend.  No hardware issues and right now there is no load.  I am just bringing it up and validating the environment.17:56
jgriffiththrowsb1: so you were trying to do boot-from-volume in Horizon there?17:56
*** arnewiebalck_ has joined #openstack-cinder17:56
throwsb1correct, going through ui to create a new vm instance.17:57
jgriffithThat's always been pretty sketchy as far as timing because the image download/conversion/copy process takes way too long17:57
jgriffithThe only real options that work reliably:17:57
jgriffith1. Turn on image caching and pre-populate some images (assuming your backend supports it)17:58
jgriffith2. Bump the timeout in Nova (like you did)17:58
jgriffith3. Don't do it that way, instead create a bootable volume in Cinder outside of Nova then use it17:58
jgriffithoption `3` works the best, but nobody likes doing the extra step :(17:59
throwsb1when you say pre-populate, I am assuming I did that by loading os image, e.g. ubuntu than deploy from there.17:59
throwsb1do you have a good recommendation for storage to use with openstack?  I am new and coming from vnmare with SAN, I thought that would be a good fit.18:02
jgriffiththrowsb1: So by prepulate I mean creating a cache entry; like `cinder create --image <image-id> xxxx`18:02
jgriffithIf you have caching configured and it's supported by your backend that should create a cache copy for future use18:02
jgriffiththrowsb1: what backend BTW?18:02
throwsb1it is old HP SAN 8GB 2path fibre18:03
jgriffiththrowsb1: ok, I can't help you there with if it works there or not18:03
throwsb1this is a prod like POC that will lead into full rollout18:03
throwsb1jgriffith: I was more or less asking is there a preferred storage option that works well.  SAN, NFS, ceph, ...18:04
SwansonRe-stacking after a month is the most fun ever.18:05
jgriffiththrowsb1: well... personally I try NOT to make endorsements in here18:05
jgriffithWe all have our biases, given most of us work on one or more of the backends supported in Cinder18:05
SwansonBuy dell emc for everything.18:06
jgriffithAny iSCSI is usually a good start IMO, and of course Ceph is an extremely popular choice18:06
jgriffithThey ALL have their strengths/weaknesses IMO18:06
jgriffithjust depends on what you value18:07
jgriffithand don't EVERY listen to Swanson18:07
jgriffithUnless it's to make sure you do the opposite of what he says :)18:07
throwsb1ok, so it sounds like there really is no biases.  Since I am new to OS and this is a new rollout using Pike then Queens, I have always had issues with storage.  Given with Pike it was just local storage.18:08
throwsb1hahaha :)18:08
throwsb1Swanson: I come from an emc background and it is nice if you can afford it.  :(18:09
SwansonSpurge! Treat yourself!18:09
SwansonI don't know what "spurge" is and,frankly, I don't want to know.18:10

throwsb1jgriffith: thanks for the help.  With out looking I am guessing the caching is in the cinder.conf?18:14
smcginnisthrowsb1: I think this should have all the details you need: https://docs.openstack.org/cinder/latest/admin/blockstorage-image-volume-cache.html18:15
smcginnisthrowsb1: And in case it's useful, here is a listing of all the currently supported backend drivers: https://docs.openstack.org/cinder/latest/drivers.html18:16
