mkoderervponomaryov: do you have a plan to port the tempest share client to check the responses directly there?14:32
mkodererfollowing http://specs.openstack.org/openstack/qa-specs/specs/clients-return-one-value.html14:32
vponomaryovmkoderer: did not have such plans14:33
mkoderervponomaryov: I had a closer look.. it's a big refactoring...14:33
vponomaryovmkoderer: you mean update of all test files?14:34
vponomaryovit is big change, but refactoring is small14:34
mkoderervponomaryov: yep, we would need to update all base classes and test cases14:34
vponomaryovmkoderer: you need it for porting scenario tests to tempest?14:36
mkoderervponomaryov: if we want to merge them back to tempest .. yes14:37
mkoderervponomaryov: but it not yet decided if Tempest is the right repo :)14:37
vponomaryovmkoderer: could  be something else? =)14:37

lpabonvponomaryov: ping18:44
vponomaryovlpabon: pong18:45
lpabonvponomaryov: hi, just wanted to discuss the review of https://review.openstack.org/#/c/166348/4/manila/api/contrib/share_unmanage.py , do you have a few minutes?18:46
vponomaryovlpabon: sure18:46
lpaboncool..18:46
*** marcusvrn1 has joined #openstack-manila18:47
lpabonmy first comment i discussed the value of share.get(..)18:47
lpabonif that returns anything other than None, then it would reject with a message, correct?18:47
vponomaryovlpabon: yes18:47
lpabonIs there a possibility that a managed share uses 'share_server_id'?18:48
vponomaryovlpabon: no18:48
lpaboni'm ignorant on this part:  Is that set by the driver or by manila upper layers?18:48
vponomaryovlpabon: else there would not be such check18:48
vponomaryovlpabon: not driver but share manager18:48
lpabonah, good.  Do drivers have the ability to set that value?18:49
vponomaryovlpabon: thing that pokes driver18:49
*** marcusvrn has quit IRC18:49
vponomaryovlpabon: only share manager updates it18:49
lpaboncool, that was my main concern18:49
lpabonsecond was on line 4918:50
vponomaryovlpabon: driver takes share server entity for creation of resources18:50
lpaboncool18:50
lpabonon line 49, i was confused on the message returned.  I think it may need to be reworded to the information you supplied on the comment reply18:50
vponomaryovlpabon: if you think it should be reworded than provide example in comment variant you think is better.18:52
vponomaryovs/than/then/18:52
vponomaryovlpabon: did I answer your questions?18:54
lpabonWhat do you think of:  "Operation 'unmanage' is not supported for shares which are running on host managed by Manila"18:55
lpabonyeah thanks!18:55
lpabonjust wanted to see if that message ^^ made sense before I placed it on the review18:55
vponomaryovlpabon: "share server" is meaning of manila18:55
vponomaryovlpabon: concrete meaning, that used within DB model, etc18:55
vponomaryovAPI...18:55
lpabonah, I see.18:55
lpabonso is this string for developers or for administrator18:56
vponomaryovanyone18:56
lpabonok, then we should probably reword it in a way that is easy for those unfamiliar with the project to understand ( like me :-) )18:57
vponomaryovlpabon: would quotes help you ?18:59
vponomaryovlpabon: meanings in quotes18:59
vponomaryovlpabon: because error message should use it anyway18:59
lpabonHmm, i think so18:59
lpaboni think the biggest issue i had was that "share server" == Manila19:00
vponomaryovlpabon: same about "share-network" that is in the end of message19:00
lpaboni did not see that19:00
vponomaryovlpabon: mm, if you thought "share server" == Manila, then quotes won't help =)19:01
lpabonAlso would it be "not supported" or "not allowed".. would we ever support it?19:01
lpabonlol19:01
vponomaryovlpabon: it is not supported yet19:01
vponomaryovlpabon: but definitely may be in future19:01
lpabonah, cool19:01
lpabonok, well, i'm not sure if I understood it.. let me try to see if I can decypher what the message means now:...19:02
vponomaryovlpabon: challenging, eh? =)19:03
*** rcallawa has quit IRC19:03
lpabonIt means that the operation 'unmanage' is not supported on a share which has already been created and managed by Manila... I'm I close?19:03
lpabonyeah, details details details.. always tough19:04
*** csaba has quit IRC19:04
*** netapp has quit IRC19:04
vponomaryovlpabon: no19:04
lpabondoh!19:04
*** netapp has joined #openstack-manila19:04
*** csaba has joined #openstack-manila19:04
lpabonok, do you mind explaining it to me, sorry I am confused19:05
vponomaryovlpabon: "manage" is API, that allows us to "register" already existing sharesupported only for shares where19:05
vponomaryovs/sharesupported only for shares where/share./19:06
*** rcallawa has joined #openstack-manila19:06
vponomaryov lpabon: also we have two driver modes19:06
vponomaryov lpabon: one where manila creates some VMs for hostng of share, and second when does not19:06
vponomaryov lpabon: these "some VMs" are called "share servers" in manila19:07
vponomaryov lpabon: so, API "manage" can be applied only for some backend which is enabled in one of two modes19:07
vponomaryov lpabon: and second has no support19:07
lpabonah i see. so..19:08
vponomaryov lpabon: when manila does handle VMs (share servers), then it is impossible to have some precreted share19:08
lpabonsorry, continue19:08
vponomaryovs/precreted/precreated/19:08
lpabonoh i see, so the 'share_server_id' is the id of the VM which provides network isolation?19:09
vponomaryov lpabon: just VM, it can provide network isolation and can not. Both are possible19:09
lpabonok, cool, i get it 8-)19:10
*** erlon_away has joined #openstack-manila19:10
vponomaryovgreat19:11
lpabonOk, so.. then the message means, that unmanage is not supported for shares which are served from share servers...19:11
vponomaryovyes19:11
* lpabon is crossing fingers19:11
lpabonyes!19:11
vponomaryovlpabon: as well as "manage". So, this is fix for making them to be in sync19:12
lpabonok, so.. now if i can suggest a message:   "Operation 'unmanage' is not supported for shares which are manged by share servers" .. how is that ? close?19:13
lpabons/manged/managed/19:13
vponomaryovlpabon: "managed by share servers" overlaps existing meanings19:13
lpabonhmm, ok19:13
vponomaryovlpabon: "managed" will mean that this share was created using "manage" API19:14
lpabon "Operation 'unmanage' is not supported for shares which are serviced by share servers" ?19:14
lpabonsomething like that19:14
vponomaryovlpabon: and, moreover - not BY share servers19:14
lpabonah ok19:14
vponomaryovthey are both subjects19:14
lpabonok, i understand your message now19:17
vponomaryovlpabon: have you tried manila on lab, at least, once?19:18
lpabonJust hoping there would be a way to simplify it, but it is hard to understand without having the correct background.19:18
lpabonvponomaryov: i'm working on setting it up.  It has been harder than i thought19:18
vponomaryovlpabon: not harder tha other projects19:19
lpaboni was able to setup swift in about 15 mins.. lol19:19
vponomaryovs/tha/than/19:19
lpabonyeah, but swift doesn't need other openstack components19:19
lpabonso you are probably right19:19
*** marcusvrn has joined #openstack-manila19:19
vponomaryovlpabon: nova setup is much harder19:20
lpabonyeah!19:20
lpabonI have been trying to use https://wiki.openstack.org/wiki/Manila/docs/Setting_up_DevStack_with_Manila_on_Fedora_2019:20
lpabonbut it seems to fail at some steps.. maybe the doc is old?19:21
lpaboni'm using ubuntu 14.04.1 lts for simplicity.19:21
vponomaryovlpabon: link provided by you contains deprecated info, at least, about devstack19:22
lpabonoh bummer19:22
*** marcusvrn1 has quit IRC19:22
vponomaryovlpabon: approach for devstack was changed not so far ago19:22
*** erlon_away is now known as erlon19:23
lpabonvponomaryov: here is my localrc: https://github.com/lpabon/devstack-manila/blob/master/roles/devstack/templates/localrc.j219:23
erlonhi guys, is anyone else having problem installing manila in devstack?19:23
erlonhttp://paste.openstack.org/show/195529/19:23
lpabonerlon - i have been trying for 1 week :(19:23
erlonim getting this error, it looks like the plugin from github is not updated19:24
lpabonerlon: i'm working on creating this:  https://github.com/lpabon/devstack-manila  -- but does not seem to be correct yet19:24
erlonlpabon: it stops in the same error?19:24
vponomaryoverlon: I am sure you used "hooks" - previous approach and did not remove them19:24
vponomaryoverlon: in other words - manila is trying to be installed twice19:25
lpabonerlon: no, i do get a correct devstack installation -- or i mean -- it finishes19:25
vponomaryoverlon: just remove any alien files for devstack19:25
erlonvponomaryov: you mean, from a previous devstack run?19:26
vponomaryoverlon: no, I mean from previous approach for manila installation19:26
erlonvponomaryov: ok, ill start fresh again19:27
vponomaryoverlon: remove files lib/manila and extras.d/70-manila.sh19:27
vponomaryoverlon: from devstack19:27
erlonvponomaryov: hmm, ok, makes sense, I was about to patch the manila pluguin and comment the duplicated functions. ill try that19:28
erlonshouldn't this be documented on the wiki?19:28
erlonvponomaryov: https://wiki.openstack.org/wiki/Manila/KiloDevstack19:28
lpabonvponomaryov: i think my main issue is that when I create a devstack vm (all in one), and I shutdown, it doesn't come back it in the same state after running ./rejoin-stack.sh19:28
erlonlpabon: ./rejoin-stack.sh never works for me19:29
lpabonerlon: doh!19:29
erlonlpabon, I always have to start from zero19:29
vponomaryoverlon: https://wiki.openstack.org/wiki/Manila/KiloDevstack provides correct information19:29
erlonvponomaryov: how about the steps you mentioned to remove lib/manila and extras.d?19:30
vponomaryoverlon: they are absent in normal case19:30
vponomaryoverlon: just answer question, your devstack lib is older than month?19:31
vponomaryovs/lib/dir/19:31
erlonvponomaryov: yes, but I pulled the new changes from upstream19:31
vponomaryoverlon: and did not removed old files19:31
erlonvponomaryov:19:32
erlonhmm19:32
erlonvponomaryov: ok19:32
vponomaryoverlon: so, it is common situation when you have artifacts that breaks something19:32
lpabonthat's why i'm setting up in vagrant19:33
vponomaryovlpabon: tracking git repo is easier than to setup vagrant19:34
lpabonfor devstack or manila?19:35
vponomaryovlpabon: in general. It said to "that's why"19:35
lpabonI'm not sure.  My plan is to track the repo and verify patches (my own in the future)  using vagrant VMs so that I can easily create clean systems19:36
lpabonThe problem i have now is how to shutdown and bring up openstack .. I would have thought 'rejoin-stack' would have done that for me19:37
lpabonmake sense?19:37
vponomaryovlpabon: what's wrong with "restack' for you?19:37
vponomaryovlpabon: there are just two common things that should be hacked after restart of devstack host19:38
lpaboni don't see restack..19:38
vponomaryov'rejoin-stack'  =)19:38
lpabonah, a couple of weird things19:39
*** dustins has joined #openstack-manila19:39
lpabonfirst, no losetups for the cinder volumes automatically19:39
vponomaryov1) if for Cinder used LVM driver, which is default, then volume group should be restored19:39
vponomaryovyes ^19:39
vponomaryov2) Nova VMs should be poked manually for start19:39
vponomaryovfrom "shutdown" state19:39
lpabonfirst, no losetups for the cinder volumes automatically qrouter in 'ip netns' only the qhdcp19:39
lpabonsecond .. qrouter in 'ip netns' only the qhdcp19:40
lpabonsecond .. qrouter is not there in 'ip netns' only the qhdcp19:40
lpabonok19:40
lpabonalso, manila always fails on rejoin stack..19:40
lpabonseems to be a race issue with ampq or something.. i can grab the error19:41
lpaboni can restart it and then it works19:41
