FL1SKCan someone help explain the LXC Driver16:37
FL1SKdoes this work with nova-docker16:37
vponomaryov1FL1SK: Manila does nto have that driver and no, it does not use neither Nova nor docker16:38
*** merooney has joined #openstack-manila16:38
vponomaryov1FL1SK: if you mean the one that was in Manila some time during MItaka16:38
*** gregsfortytwo1 has quit IRC16:39

*** gregsfortytwo has joined #openstack-manila16:43
*** BitSmith has joined #openstack-manila16:43
*** merooney has quit IRC16:45
FL1SKvponomaryov1: yeah during mitaka16:45
FL1SKdidn't mitaka release an LXC driver16:45
vponomaryov1FL1SK: didn't16:46
FL1SKvponomaryov1: I thought I saw a blue print for it16:46
FL1SKvponomaryov1: https://docs.google.com/document/d/1ulMZEWKz7yTWSDtfaHjux0DaXbVr4egCv22_auwrcn8/edit#16:46
FL1SKhttps://blueprints.launchpad.net/manila/+spec/lxc-driver16:46
vponomaryov1FL1SK: driver was removed as LXC response data structure was changing significantly16:47
FL1SKoh...16:47
FL1SKouch16:47
vponomaryov1FL1SK: LXC hadn't stable release16:48
FL1SKSo what now for containers16:48
vponomaryov1FL1SK: in Mitaka - nothing16:48
FL1SKNewton16:48
vponomaryov1FL1SK: in Newton - Docker is under development16:48
FL1SKAh Ha16:48
FL1SKwhere is the blueprint for that16:48
vponomaryov1could be absent16:49
FL1SKof course16:49
FL1SKis there any code tree that indicates it16:49
vponomaryov1just know that work goes on it16:49
*** merooney has joined #openstack-manila16:49
FL1SKbug, feature enhancement16:49
vponomaryov1code with intermediate variant?16:50
FL1SKManila community is not keeping up with blueprints and things etc.. very well right vponomaryov116:50
FL1SKvponomaryov1: where is some code i can see that proves work on Docker16:50
vponomaryov1FL1SK: you are free to do not beleive me ))16:51
vponomaryov1FL1SK: removed LXC driver code is a basis for it16:51
FL1SKI believe you vponomaryov1, I just want somethign solid for my session at OpenStack Summit16:52
vponomaryov1FL1SK: there is no solid thing16:52
FL1SKalright16:52
vponomaryov1FL1SK: so, now, you can consider it as intention16:52
FL1SKfor Newton16:52
FL1SK:-)16:52
vponomaryov1yes16:52
FL1SKMaybe roll it into Generic driver16:52
vponomaryov1no, generic driver has its own field - Nova16:53
vponomaryov1and CInder volumes16:53
FL1SKok16:53
FL1SKmakes sense16:53
vponomaryov1if you enable containers under ok - still ok16:53
vponomaryov1under Nova*16:53
bswartzThe goal of the "container" driver is to not depend on other projects such as nova and cinder16:53
FL1SKyeah Nova-Docker16:53
FL1SKok makes sense bswartz16:53
FL1SKbswartz: whats a good use case for the container driver16:54
vponomaryov1bswartz: do we have BP for docker driver?16:54
bswartzinitially we went with LXC/LXD but that project proved to be too unstable for us, so now we're strongly considering docker16:54
FL1SKbswartz: Cool16:54
bswartzFL1SK: we need a reference implementation of a share backend which support the Manila "share server" concept16:54
bswartzshare servers need to be virtualized instances of an NFS or CIFS server specific to 1 tenant16:55
FL1SKok16:55
FL1SKSo this would create a share server in a container16:56
vponomaryov1FL1SK: "share server" is definition for manila, "container" is a share server for Manila16:56
bswartzvponomaryov1: aovchinnikov would know better than I about the BP -- if there is not one we need to create it an add it to N-116:56
*** jasonsb has joined #openstack-manila16:56
bswartzFL1SK: we'll use containers to get the appropriate level of network and namespace isolation between share servers16:57
vponomaryov1FL1SK: it is name for tracking created resources such as "compute" entity, in current case - container16:57
bswartzfull virtualization achieves the same effect but with higher costs16:57
FL1SKi got it16:58
FL1SKmakes sense16:58
*** mtanino has joined #openstack-manila17:14

FL1SKWhat does LVM stand for in the LVM driver17:49
FL1SKis it Linux Virtual Machine17:49
FL1SKor Logical Volume Management17:50
*** Yogi1 has quit IRC17:51
*** vbellur has quit IRC17:51
akerrFL1SK: logical volume management17:56
FL1SKthought so17:56
FL1SKdidn't make sense the other way17:56
FL1SKcan you explain how the LVM share driver is working17:57
FL1SKis there a blueprint akerr17:57
akerrFL1SK: I think it creates a new LVM devices for each share and exports it over NFS17:57
akerrFL1SK: https://blueprints.launchpad.net/manila/+spec/lvm-driver17:58
*** esker has joined #openstack-manila17:59
FL1SKakerr: interesting18:01
FL1SKSo it would take a raw device on a dedicated storage system and put that into an LVM and then create an Export with it18:01
FL1SKWhat filesytem would it use18:01
akerrbswartz: ^18:02
akerrFL1SK: i'm only familiar with the general concept of the driver unfortunately, but bswartz or vponomaryov1 can probably give you a lot more details18:03
FL1SKthanks akerr18:03
bswartzFL1SK: akerr is correct18:03
bswartzFL1SK: the filesystem is configurable but default to ext3 IIRC18:03
FL1SKok18:04
bswartzLVM is intended to be to absolute simplest reference driver possible18:04
FL1SKthanks bswartz, does it just take available raw and put those into LVM then?18:04
FL1SKok bswartz that makes sense18:04
bswartzFL1SK: you have to create a pv and vg manually18:04
bswartzand give that to the driver18:04
FL1SKbswartz: ok thats understandable now18:05
FL1SKthanks bswartz18:05
*** lpetrut has quit IRC18:09
*** winston-d_ has joined #openstack-manila18:13
FL1SKbswartz: can you tell me about lvm share mirrors18:32
FL1SKwhats the requirement there18:32
FL1SKlvm_mirrors18:33
FL1SKare those created manually18:33
bswartzFL1SK: looks like the driver does it for you18:34
FL1SKbswartz: is that right18:34
bswartzI didn't write that code and honestly I'm surprised to see it18:34
FL1SKDoes it recognize the mirrors being from two different servers18:35
bswartzhttps://github.com/openstack/manila/blob/master/manila/share/drivers/lvm.py#L8418:35
FL1SKor just mirrors within same share system18:35
bswartzif that option is set it appear to add a "-m" argument to lvcreate18:35
FL1SKah ha18:35
FL1SKgotcha18:35
FL1SKi see that18:35
FL1SKCool18:36
FL1SKbswartz: looks like its only a plus 1 copy18:37
FL1SKso thats hard coded18:37
FL1SKoh wait no this is configurable18:38
FL1SKhmm18:38
FL1SKso its +n18:38
bswartzin any cases it seems to just increase resilience against a local disk failure18:39
FL1SKyup18:39
FL1SKnot bad18:39
FL1SKlvm_share_mirrors allows you to change the total number of mirrors18:40
FL1SKinteresting18:40
