jgriffithsmcginnis: hey... I'm fixing the rootwrap on that env patch for LVM...15:30
jgriffithsmcginnis: I was wondering about privsep and brick?15:31
smcginnisjgriffith: Oh good!15:31
smcginnisjgriffith: Sure, what's up?15:31
jgriffithsmcginnis: it looks like it need/reads in from Cinder's rootwrap?15:31
smcginnisjgriffith: Hmm, shouldn't be.15:31
smcginnisjgriffith: Looking now. But one of the main reasons for privsep was to get rid of the need to have a rootwrap filter file.15:32
jgriffithsmcginnis: yeah :)15:32
jgriffithsmcginnis: http://logs.openstack.org/75/365175/1/check/gate-os-brick-python27-ubuntu-xenial/4794390/console.html15:32
jgriffithsmcginnis: so that statement is probably wrong.. but I can not figure out how to add the privsep stuff15:33
jgriffithsmcginnis: so I added it to the test I thought and that didn't work, then started wondering how this will work with Cinder in the future15:33
jgriffithsmcginnis: http://logs.openstack.org/75/365175/1/check/gate-os-brick-python27-ubuntu-xenial/4794390/console.html15:34

smcginnisjgriffith: Is that just a unit test/mocking issue?15:35
jgriffithsmcginnis: probably :)15:35
smcginnishemna: We're talking one of your favorite subjects. :)15:36
avishayhemna, jgriffith: any idea about this bug? it's blocking me... https://bugs.launchpad.net/cinder/+bug/161994115:36
openstackLaunchpad bug 1619941 in Cinder "os-brick returns wrong iscsi device path" [Undecided,New]15:36
jgriffithsmcginnis: but when looking at it, it raised some questions for me regarding how the whole privsep thing is going to work and I couldn't find any answers15:36
jgriffithavishay: looking15:36
hemnais it "Fun with privsep" day ?15:36
jgriffithavishay: haha... my favorite!!!15:36
smcginnishemna: ;)15:36
avishayjgriffith, you know this issue?15:36
jgriffithavishay: Not this one inparticular but I get all sorts of random failures in brick around the targets15:37
hemnalaunchpad isn't coming up for me15:37
jgriffithavishay: I'll look and see if there's anything I can figure out if/when I get past this silly test thing15:37
* hemna waits15:37
jgriffithavishay: oh15:38
smcginnisjgriffith: So that failure does look like it's just a unit test that needs to be updated.15:38
jgriffithavishay: hmm... ok, I think I know how to fix that15:38
hemnaso, that's a udev rule that creates those paths fyi15:38
smcginnisjgriffith: But the bigger question around privsep, I remember an overview somewhere. I'll see if I can find that.15:38
jgriffithsmcginnis: yeah.. but the problem is if you look I have the _lvm_env added to fake_execute in the test15:38
jgriffithsmcginnis: haha.. unless we're calling a different fake_execute :)15:38
smcginnisjgriffith: Hah, wouldn't be the first time something like that has happened. ;)15:39
avishayhemna: yep, i looked into it but the udev rule seems to just create the path according to what it gets from the kernel, which gets it from god knows where15:39
jgriffithavishay: I think the way to address that is that I just add the port number to the model explicitly all the time.  IIRC that should work, but I'll have to verify15:39
*** andymaier has quit IRC15:39
jgriffithavishay: unless brick does something goofy like filter things out and do it's "own" thing :(15:39
avishayjgriffith: what do you mean by model?15:40
jgriffithavishay: the provider info in the model15:40
jgriffithavishay: provider_location15:41
jgriffithiscsi_portal iqn 015:41
hemnaavishay, so, I can add another set of search paths that also include the port #15:41
avishayjgriffith: os-brick just creates the path like i wrote in the bug - "/dev/disk/by-path/ip-%s-iscsi-%s-lun-%s"15:41
avishayhemna: yea that's what i was thinking15:41
*** zhangguoqing has quit IRC15:41
avishayjgriffith: hemna: i'm just wondering why i'm the first person to hit this bug15:41
hemnait's pretty easy to do15:41
avishaythat's my real concern15:42
hemnafwiw, I've never seen one w/ a port #15:42
*** pcaruana has joined #openstack-cinder15:42
hemnabut each distro has different udev rules for the creation of those paths15:42
avishayhemna: we've tested iSCSI against LVM, EMC, NetApp, Dell, and some others.  Solidfire was the first this happened with.15:42
hemnaI'd debug the udev discovery15:43
jgriffithhemna:  avishay if it's not setting the "ip-xxxxxx" based off of the provider_info string exactly then it's wrong.  Regardless of distro15:43
hemnait's probably adding that15:43
jgriffithand regardless of udev15:43
avishayjgriffith: i didn't see where it gets it from, will check...15:43
jgriffithanyway, I'd have to look at it and I don't know why it's just now showing up for avishay that's no good15:44

hemnait's a good watch.  I've seen it15:48

jgriffithsbezverk: oh... you had a  follow up question :)19:29
jgriffithsbezverk: i'm kinda stuck on that review BTW19:30
jgriffithsbezverk: http://lists.openstack.org/pipermail/openstack-dev/2016-June/098294.html19:30
jgriffithsbezverk: we've decided that things like rootwrap shouldn't change19:30

*** alwaysatthenoc has joined #openstack-cinder19:31
jgriffitheharney: oh.. thanks!19:31
sbezverkjgriffith: hm, bad news for us then :-(19:31
eharneyjgriffith: but something like that should work for cinder if needed19:31
*** coolsvap_ has quit IRC19:32
erloneharney: that's required because by default, libvirt spawns the qemu processes as libvirt:kvm. Then you have a problem because cinder is running as cinder:cinder or other user, and is unable to access the volume file19:32
jgriffithsbezverk: so in your follow up question... I don't think you want that19:32
jgriffithsbezverk: I'll figure that out19:32
jgriffithsbezverk: back to your other question about conf entries19:32
eharneyerlon: do you have dynamic_ownership=1 turned on?  because it should handle that19:32
erloneharney: when you set the user/group in qemu.conf, the qemu process has the same permissions as Cinder19:32
sbezverkjgriffith: right please clarify19:32
jgriffithsbezverk: that syntax you have is for multi-backend configs; ie multiple c-vol services running on a single node19:33
jgriffithsbezverk: but in the case of containers you don't want to do that19:33
sbezverkjgriffith: nope19:33
*** alwaysatthenoc has left #openstack-cinder19:33
erloneharney: where should this conf be set?19:33
sbezverksince ip addresses are different it is multinode19:33
jgriffithsbezverk: you want an individual container for each c-vol and each of those needs it's own unique cinder.conf file19:33
eharneyerlon: same place, libvirt/qemu.conf19:33
erloneharney: ok19:33
eharneyerlon: when that's on (which i thought it was by default), libvirt will chown/chmod the files as needed19:34
jgriffithsbezverk: if you do like you have there it will try and run all of those in a single container on every container :(19:34
erloneharney: ill check19:34
*** Apoorva has quit IRC19:34
erloneharney: the problem is that roosquash does not allow chown19:34
erloneharney: Im running rootsquash19:34
eharneyerlon: i think you have to have root squash off at this point19:34
sbezverkjgriffith: got it, so it is preferable to have only relevant config19:34
jgriffithsbezverk: yes for sure19:35
jgriffithsbezverk: multi-backend is a special case that's kinda become a default :)19:35
jgriffithsbezverk: ignore it19:35
sbezverkjgriffith: it just complicates the logic but should be doable19:35
jgriffithsbezverk: you're better off and more easily scale without it19:35
*** alonma has quit IRC19:35
sbezverkjgriffith: thank you for clarification..19:36
jgriffithsbezverk: sure19:36
erloneharney: yes, it defaults to 119:36
jgriffitheharney: interesting... so if we fully recognize that we're doing this on purpose and it's REALLY REALLY what we want  it *might* be ok :)19:37
jgriffitheharney: that aligns with the ML thread I posted19:37
jgriffitheharney: thanks!19:37
eharneyjgriffith: maybe so, it's been a long while since i looked at it, so i'm not sure what the current thinking is19:37
jgriffitheharney: I'll let ya know after I get flame sprayed :)19:37
erloneharney: but if that is set, we fall in the same permission problem, and the snapshots will only work with security_mode=False19:39
jgriffitheharney: looks like that's the right approach https://github.com/openstack-dev/grenade/tree/master/projects/60_nova/from-mitaka19:40
jgriffitheharney: thanks once again19:40
*** rcernin has joined #openstack-cinder19:41
scottdaeharney: If I want to add thin_provisioning_tools to devstack to fix https://bugs.launchpad.net/cinder/+bug/1615134 , does the bug stay as a "cinder" bug? Or does it need to change to "devstack"?19:41
openstackLaunchpad bug 1615134 in Cinder "volume create fails in /usr/sbin/thin_check" [Undecided,New]19:41
eharneyerlon: my opinion is that the secure mode stuff seems to have a few other problems anyway, so that's a fine starting point19:42
scottdaeharney: I'm thinking it should be Devstack bug...19:43
eharneyscottda: IMO we shouldn't change Cinder to do anything there, so it should just move to the devstack component19:43
scottdaeharney: Thanks.19:43
eharneyscottda: Ubuntu's packages seem kinda broken there, but i dunno how easily we can change that19:43
erloneharney: what other problems?19:43
eharneyerlon: we've had to advise a customer or two to turn it off due to seeing some other failures -- i don't recall what they were at the moment19:44
erloneharney: I think that adding the option to allow secure mode with some configuration in compute nodes its a better starting point than not having it at all19:45
eharneyerlon: sure, i think it's a great idea.  I just think it needs some further work to actually work right.19:45
erloneharney: and it won't change the behavior of the no_secure configuration19:45
*** sdake has quit IRC19:46
erloneharney: ok, ill push the changes I made so you can have a look, but basically I removed the places were you call run_as_root=True, and changed it to self._execute_as_root19:47
*** xinli has quit IRC19:47
eharneyerlon: i'm pretty sure that some of those were done that way because in cases where qemu-img needs to read from the qcow2 headers and the files are attached/owned by libvirt/qemu, it will fail if not run as root19:48
eharneyerlon: there's a comment in nfs.py:424 to that effect19:48
*** rcernin has quit IRC19:48
scottdaeharney: and others, fix for thin_provisioning on (Ubuntu) devstack: https://review.openstack.org/#/c/366309/19:50
erloneharney: exactly, but it just does not make sense to have some commands running as root while others are as user. If there's any command running as root, the setup can't be called secure, as the admin could be lead to believe19:51
erloneharney: so, the idea is either run insecure with norootsquash, or run secure, with the aditional configuration on computes and rootsquashing19:52
eharneyerlon: i dunno about that argument.  But the fundamental error that the nas_secure work made was that it mixed up the two questions of "who owns these files?" and "should these commands run with sudo?" in a way that needs to be fixed now19:52
erloneharney: hmm19:54
erloneharney: what would be the ideal behavior of the nas_secure?19:54

smcginnisjgriffith: Part of the reason to go to privsep was to get away from rootwrap and the need to change the filter file on upgrade.20:07

smcginniserlon: Or lack thereof? :)20:09
erlonsmcginnis: is there a good place to put it inside cinder repo or only in openstack manuals20:09
erlonsmcginnis: yeaah20:09
smcginniserlon: Right now there's only the devref in the cinder repo. Which as its name implies is a reference for development.20:09
smcginniserlon: But we are starting to get more and more that I'd like generally published like the sample.conf, etc.20:10
smcginniserlon: So I think right now openstack-manuals is the only logical place, but maybe that will change.20:10
openstackgerritMerged openstack/os-brick: Remove self.__dict__ for formatting strings  https://review.openstack.org/36404420:10
smcginniserlon: You could add info to the devref, even though it's not a great fit. But at least somewhere else to capture details for now if it makes sense.20:10
