anteayajgriffith: I understand your position and agree with you, cinder and neutron are very different in how drivers are regarded00:06
anteayajgriffith: I don't know how many on the tc recognize how different they are00:07
jgriffithanteaya: yeah, makes it interesting00:07
anteayavery interesting00:07
anteayaI think some folks on the tc are about to get more of an education than they bargain for on this00:07
jgriffithanteaya: frankly I wouldn't expect the TC to help if *we* as a team (cinder) can't figure it out00:07
jgriffithhaha00:07
jgriffithanteaya: perhaps00:08
anteayayeah it will be interesting what shakes out now that out of tree drivers feel they should be in governance00:08
anteayawith the argument they were before when they were in tree00:08
jgriffithanteaya: I still haven't digested all of that, need to look through it some more this evening00:08
anteayayup00:08
anteayalots to digest00:08
jgriffithanteaya: it seems they've gone back and forth a couple times at this point00:09
anteayaI believe it00:09
jgriffithanteaya: oh well.. there goes my dream of Cinder drivers being out of tree some day :(00:09
jgriffithRIP good idea00:09
anteayathe thing that gets me is the folks arguing for including them in governance can't seem to get a handle on what open source means00:09
*** leeantho has quit IRC00:09
jgriffithWe'll just continue having half the driver in tree and the other half out00:09
anteayayeah, it might mean the end of that approach00:09
jgriffithanteaya: yeah, I've come to the conclusion that Open Source doesn't really have a well defined meaning here any more00:10
anteayathis may be an opportunity for it to be reasserted00:10
anteayaor not00:10
*** faiz89 has joined #openstack-cinder00:11
anteayabut yeah it is very disappointing that many folks don't seem to be able to grasp the basics00:11
jgriffithanteaya: "what's wrong with requiring my proprietary lib for Cinder to work"...   ME:  OpenStack is an Open Source project... Them:  "what's wrong with requiring my proprietary lib for cinder to work"00:11
jgriffithround and round and round00:11
anteayayep00:11
jgriffithanteaya: nope00:11
anteayayeah :(00:11
jgriffithoh well.. on that note, I'm going to drive home00:11

thisisdos1984hi Guys15:52
thisisdos1984is there a way to do Nova quince before taking cinder snapshot ?15:53
*** jgriffith_away is now known as jgriffith15:53
smcginnisthisisdos1984: I don't believe so. That would have to be driven from the nova side to tell Cinder to snap once it's been quiesced.15:53
*** maestropandy has quit IRC15:55
jgriffithsmcginnis: we talked in ATL about this... once Nova is ready and comfortable that they will be on a new enough version of libvirt, we could implement a call "to nova" to quiesce, then snap"15:56
smcginnisjgriffith: Oh, that's right. You need a recent version of libvirt for that functionality, right?15:57
smcginnisMore recent than 14.04's default IIRC.15:57
jgriffithyeah15:57
thisisdos1984hmm .. so u mean, 1. nova quiesce 2. nova snapshot 3. cinder snapshot 4. nova unquiesce ?15:57
jgriffithsmcginnis: IIRC that was the only real hurdle15:57
jgriffiththisisdos1984: no15:57
thisisdos1984then ? sorry to trouble you guys !15:58
*** jgregor has joined #openstack-cinder15:58
jgriffiththisisdos1984: so cinder snapshot ----> cinder-"is volume attached" if yes:  Call nova to quiesce, wait for ok, then snap, tell nova it can have it back"15:58
jgriffiththisisdos1984: keep it in Cinder15:58
scottdaI think nova uses quiesce for live migration...not sure of that, though.15:58
*** akshai has quit IRC15:58
smcginnisthisisdos1984: Nova shouldn't need to snap. It just needs to quiesce the VM so cinder's snap to be consistent.15:58
*** rlrossit_ has quit IRC15:59
jgriffithsmcginnis: right... everything orchestrated by cinder15:59
smcginnisjgriffith: Well, I guess I could see it from either side. It just needs to be coordinated.15:59
*** akshai has joined #openstack-cinder15:59
jgriffithsmcginnis: right, but given that the call is going in to Cinder you want it coordinated on that side15:59
smcginnisMaybe even by something like smaug. The only issue is being able to do it quick enough not to cause trouble for the guest OS.16:00
*** sayalilunkad has quit IRC16:00
jgriffithsmcginnis: you can have nova coordinate a "cinder snapshot xxxx" call very well :)16:00
jgriffiths/can/can't/16:00
jgriffithsmcginnis: it would end badly :)16:00
*** xyang has joined #openstack-cinder16:00
thisisdos1984ok .. so current cinder snapshot does not have this option to call to nova to quiesce .. am i right?16:00
jgriffiththisisdos1984: hehe... correct16:01
smcginnisjgriffith: Not sure if nova would like something else outside telling it to zombify a VM and maybe not come back though. ;)16:01
hemnaI think it also requires an agent in the guest to work correctly too16:01
jgriffithsmcginnis: then we never implement the feature16:01
thisisdos1984:)16:01
jgriffithhemna: nope16:01
smcginnishemna: I think you're right - to get it truly consistent.16:01
jgriffithhemna: that's the beauty of the command16:01
thisisdos1984nooooooo .. we need consistent snapshots right?16:01
jgriffithhemna: it just freezes the instance so you don't have to worry about it16:02
hemnaI believe the fs inside the guest has to be frozen16:02
smcginnisjgriffith: That doesn't always work though.16:02
jgriffithhemna: that's what the libvirt command does :)16:02
hemnabecause of the heavy linux ram caching16:02
smcginnisjgriffith: The OS might need to know to flush out cached IO, commit transactions to be application consistent, etc.16:02
jgriffithanyway, it's all kind of irrelevant right now16:02
smcginnisjgriffith: True! :)16:02
hemnasmcginnis, that's what I thought as well16:03
thisisdos1984so John, r u trying to say that its unsafe to call freeze from cinder side ?16:03
*** leeantho has joined #openstack-cinder16:03
jgriffithhemna: smcginnis the queisce command in libvirt does exactly that IIRC16:03
*** esker has joined #openstack-cinder16:03

jgriffithhttps://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/quiesced-image-snapshots-with-qemu-guest-agent.html16:04
smcginnisI know from the Windows side, you need something to talk to the VSS service to coordinate everything within the guest.16:04
smcginnisOh, there you go, guest agent. :P16:04
hemnahttp://wiki.libvirt.org/page/Qemu_guest_agent16:04
* jgriffith doesn't know why he even said anything16:05
smcginnis:)16:05
*** alonma has joined #openstack-cinder16:05
jgriffiththe bottom line is we don't have the ability to do it currently16:05
jgriffithwe'd need to implement *things* in Cinder and Nova to do it16:06
smcginnisYep, like you said, irrelevant at this point.16:06
*** liverpooler has joined #openstack-cinder16:08
*** alonma has quit IRC16:10
xyangjgriffith: regarding that guest agent, I thought there were several proposals in the past to add an API in Nova so it can be called outside of Nova, but they were all rejected.16:10
xyangjgriffith: I'm trying to find a link16:10
jgriffithxyang: yeah, I don't know current status16:11
jgriffithxyang: like I said, I should've just kept quiet :)16:11
xyangjgriffith: maybe this is the one: https://blueprints.launchpad.net/nova/+spec/expose-quiesce-unquiesce-api16:12
jgriffithrather than going in the weeds :)16:12
jgriffithxyang: yeah, I saw that one... also saw it's been rejected/abandoned :(16:13
xyangjgriffith: and that was not the first time this idea was rejected either16:13
jgriffithxyang: sadly no it is not16:13
openstackgerritAlexey Khodos proposed openstack/cinder: NexentaStor5: add extend method to NFS driver  https://review.openstack.org/29788016:13

thisisdos1984no no, please dont be quiet .. newbies like me need help from u guys16:14
xyangjgriffith: same here:)16:14
jgriffithxyang: those previous proposals were better and more detailed than I could've ever done so if they didn't make it past the bar, no way I am going ot16:14
jgriffithto16:14
openstackgerritHelen Walsh proposed openstack/cinder: VMAX driver - failed rollback on VMAX3 when MV issue  https://review.openstack.org/35802616:16
thisisdos1984so there is no way to take consistent snapshots of entire VM16:17
xyangthisisdos1984: which driver are you using16:17
thisisdos1984lvm16:17
xyangthisisdos1984: for lvm we do need that quiesce api16:18
thisisdos1984wouldnt libvirt api in guest do the same ?16:18
xyangthisisdos1984: yes16:19
thisisdos1984sorry for asking basic questions here16:19
xyangthisisdos1984: you can call it yourself before taking the snapshot16:19
thisisdos1984so do i need to invoke the quiesce api before taking nova and cinder snaps ?16:19
scottdathisisdos1984: That was actually a good question. Thanks for asking.16:19
xyangthisisdos1984: quiesce before and unquiesce after16:20
xyangthisisdos1984: if you are taking a snapshot on nova side, it should be taken care of by nova16:20
*** venkhari has quit IRC16:20
xyangthisisdos1984: for cinder, you'll have to make a call yourself16:21
*** tesseract- has quit IRC16:21
thisisdos1984it its taken care by nova itself then it will make only Nova snapshot consistent, not cinder16:21
thisisdos1984right ?16:21
thisisdos1984if*16:21
xyangthisisdos1984: yes16:22
xyangthisisdos1984: nova does it internally16:22
thisisdos1984were there ever a requirement of making both nova and cinder consistent together ?16:22
smcginnisthisisdos1984: If you can script libvirt quiesce, cinder snap, libvirt unquiesce, then the Cinder snapshot(s) theoretically should be consistent.16:22
thisisdos1984yeah .. but not with the nova snapshot, right?16:23
*** jgregor has quit IRC16:23
smcginnisthisisdos1984: If IO is held off during that period, it should all be consistent.16:23
thisisdos1984so my backup program is like this, 1. take nova snap 2. take cinder snap 3. back up both16:24
*** kaisers has quit IRC16:24
smcginnisthisisdos1984: That sounds mostly safe. :)16:24
*** jgregor has joined #openstack-cinder16:24
xyangyou quiesce before step 1 and unquiesce after 216:24
thisisdos1984but if nova or cinder quiesce/unquiesce on their own, they wont be consistent with each other16:24
smcginnisthisisdos1984: Cinder doesn't quiesce. As long as KVM has written out its data, cinder just has to create a snapshot.16:25
thisisdos1984oh .. but that would cause double quiesce on nova side because nova does it on its own, am i right?16:25
smcginnisthisisdos1984: Not sure where you'd end up quiescing twice. Can you explain a little more?16:26
thisisdos1984ok .. does nova snapshot operation quiesce/unquiese the VM ?16:27
smcginnisthisisdos1984: Yes, I believe so.16:28
thisisdos1984now, as per your suggestion, in my backup program, if I quiesce before step 1 and unquiesce after 216:29
thisisdos1984wouldnt that cause double quiesce while taking nova snapshot ?16:29
thisisdos1984in step 116:30
thisisdos1984am I missing something ?16:31
jgriffiththisisdos1984: it kinda depends... there's a difference between ephemeral, boot-from-volume and a seondary attached volume16:31
thisisdos1984ok16:31
thisisdos1984so nova snapshot will only quiesce non-cinder volumes ?16:31
smcginnisthisisdos1984: If the nova snap is part of the quiesce then it's once, but I won't claim to know much about the mechanics between KVM and the guest.16:31
*** ametts has joined #openstack-cinder16:32
*** jungleboyj has quit IRC16:32
thisisdos1984jgriffith: so lets take one at a time .. nova snapshot creates is only about ephemeral disks, am I right?16:34
jgriffiththisisdos1984: actually no16:34
jgriffiththisisdos1984: it will also deal with boot from volume16:34
thisisdos1984damn .. i need to go back to basics here .. sorry folks16:34
thisisdos1984ok16:34
jgriffiththisisdos1984: maybe the more accurate way to say it is that it cares about the "root disk"16:35
jgriffiththisisdos1984: whether that be ephemeral, cinder-vol etc16:35
thisisdos1984cool .. thats perfect .. got it ! so i want to make root and non-root disks consistent together16:35

nikeshmCI and jenkins are happy17:46
nikeshmtested with multipath configuration in CI too17:46
smcginnisxyang1: It is soft string freeze, so I wouldn't hold up a bug fix because of it.17:46
smcginnisxyang1: We can still have some string changes. They should just be avoided is possible.17:46
smcginnisxyang1: But if it's between a string change and fixing a valid bug that someones going to run into, better to fix the bug IMO.17:47
smcginnisxyang1: Just increases the chance that we will end up with a string that is not getting translated.17:47

nikeshmone doubt: i used filter_function = "capabilities.total_volumes < 10" in cinder.conf under my backend configuration group and then i created 11 volumes concurrently without any delay17:53
*** akshai has quit IRC17:54
nikeshmit is able to create 11th volume since total_volumes stats was not updated17:54
patrickeastnikeshm: sadly thats a side effect of the scheduler caching/polling driver stats17:54
patrickeastnikeshm: same kinda thing happens with thin provisioned volumes and the way it keeps track of space between driver stat checks17:55
hemnamriedem, found another one in the AOE connector17:55
mriedemhemna: cool will get it17:56
hemnathanks17:56
nikeshmis there any way to avoid this, or we have to use some delay17:56
nikeshmpatrickeast: is there any way to avoid this, or we have to use some delay17:56
nikeshmto wait for stats17:57
nikeshmto update17:57
patrickeastnikeshm: well, the only way to make it work correctly would be to either check the driver more often, which adds load (some drivers the update is relatively slow)17:57
patrickeastnikeshm: or for something like volume count maybe the scheduler could just keep track better17:57

*** kaisers has quit IRC18:17
patrickeastnikeshm: the problem being the scheduler polls for updates of those every like 30 seconds or whatever, so between updates the scheduler is out of sync with the driver18:18
patrickeastnikeshm: what we recommend with our backend is to use the driver weigher method and have it drop weights on backends that get close to the volume limit so the scheduler won't keep pushing volumes onto the backend if there is another (better) option18:19
patrickeastnikeshm: and then have the hard limit on the driver filter_function a little bit before the actual one so there is some buffer18:20

openstackLaunchpad bug 1610395 in Cinder "RemoteFS is not working properly with privsep in os_brick 1.5.0" [Critical,New]21:33
smcginnisjungleboyj: ping ^^21:34
jungleboyjsmcginnis: Pong21:34
smcginnisjungleboyj: Do you know if that bug is still an issue? Or did you figure out what was going on there?21:36
jungleboyjsmcginnis: That is a fun one!21:37
smcginnis:)21:37
jungleboyjI did figure out what is up.  The privsep-helper program can fail in the case that there is no default set for os-brick in cinder.conf or nova.conf.21:38
jungleboyjIf doesn't normally fail, but will if you are running in a venv where the defaults don't work.21:38
hemnawasn't that due to the older privsep and rootwrap not having the hard coded privsep helper ?21:38
jungleboyjThere is not exception handling around the popen they are doing.21:39
jungleboyjhemna: Doesn't make a difference.  Still fails in the venv.21:39
jungleboyjRegardless, I need to push up a patch that reports with privsep-helper fails.21:39
hemnathe default helper is hard coded into rootwrap now though21:39
jungleboyjRight now it just silently fails and we have no idea why commands that os-brick was trying failed.21:40
smcginnisjungleboyj: So still being worked on, but probably not a Critical bug, right?21:40
jungleboyjRight, we can take critical off it.21:40

jungleboyjhemna: I can give that a try as well.21:41
hemnaalso what version of rootwrap ?21:42
jungleboyjI think we will still see issues though.21:42
jungleboyjIt was with the latest, 5.0.1 I think?21:42
hemnajungleboyj, fwiw https://github.com/openstack/oslo.rootwrap/commit/37c2a041d33f0fdce7ce2832398c1f60f3ee870321:42
hemnathat should be in 5.1.021:43
jungleboyjSorry, 5.1.021:43
hemnawhich was released on 8/1021:44
*** kaisers has joined #openstack-cinder21:45
jungleboyjhemna: I think we still have issues because our privsep-helper is in a venv and not at a default path.21:45
jungleboyjWe have to set it for os-brick or we fail unable to find the privsep-helper binary.  The exception is uncaught so it ends up looking like os-brick puked for no reason.21:46
hemnaok so reading the bug it looks like it was using rootwrap 5.0.021:46
hemnaI don't think rootwrap had the hard coded helper default then21:46
hemnawhich would cause privsep-helper to not start21:46
openstackgerritMerged openstack/cinder: Eqlx: Ignore missing snapshot on delete  https://review.openstack.org/36704321:47
hemnaso the venv bin dir wasn't/isn't in the PATH ?21:47
jungleboyjhemna: Ok.  No, which is a whole other issue.21:47
jungleboyjI will verify the library levels when I play with this tomorrow.21:48

*** alonma has joined #openstack-cinder21:50

hemnaI think that as long as the privsep-bin is in the PATH, then you should be ok due to the hard coded privsep-helper added into rootwrap22:06
