nicodemus_hello14:06
nicodemus_I have a doubt that can't seem to find in the docs14:07
*** kaisers has quit IRC14:09
nicodemus_Using the neutron network plugin and a certain share backend, do instances have to live in the same flat network as the backend?14:10
vponomaryovnicodemus_: what driver do you use?14:10
nicodemus_For the sake of my doubt, I'd be using the default backend (cinder)14:11
vponomaryovit does not use "network plugins"14:11
vponomaryovit uses its own code related to networking14:12
nicodemus_I see. However, if I wanted to use a different backend then Manila would need to use a network plugin?14:13
vponomaryovnicodemus_: it depends on drive rmode14:13
vponomaryovnicodemus_: most drivers do not use network plugins at all14:13
vponomaryovnicodemus_: but those, who use, have its own restriction14:14
vponomaryovnicodemus_: flat or segmented14:14
vponomaryovnicodemus_: so, it is driver-specific14:15
vponomaryovnicodemus_: in its own turn, it is storage-specific14:15
nicodemus_Oh, so it depends on the driver one wishes to use14:15
vponomaryovyes14:15
vponomaryovnetwork plugins allow to use both - flat and segmented networks14:15
*** kaisers has joined #openstack-manila14:17
nicodemus_Let me ask you one more thing, vponomaryov ... is there a list of the currently supported backends? Meaning, if Manila can interact directly with X storage appliance?14:19
vponomaryovnicodemus_: enjoy: https://github.com/openstack/manila/blob/master/doc/source/devref/share_back_ends_feature_support_mapping.rst14:19
nicodemus_Awesome! Thanks a lot :-)14:20
vponomaryovnicodemus_: last table says who handles networking14:20
vponomaryovnicodemus_:as you can see, only 8 driver do it, and 2 of them - Cinder based14:21
nicodemus_So, the ones that don't handle networking would require the instances to reach the backend through the underlay, meaning the instances would live in a flat network with either L2 or L3 connectivity with the backend though the legacy datacenter network14:25
nicodemus_is that correct?14:25
nicodemus_(sorry for asking again, I want to make sure I understand properly)14:25
vponomaryovnicodemus_: it means manila will not handle it14:26
vponomaryovnicodemus_: what admin configures that will be in cloud14:26
nicodemus_I see.14:28
vponomaryovnicodemus_: consider it as "users will have network connectivity to all shares"14:28
nicodemus_Thanks vponomaryov!14:28
vponomaryovnicodemus_: where only access rules will matter14:28
nicodemus_That makes sense14:28
vponomaryovnicodemus_: but, would be correct to mention14:30
vponomaryovnicodemus_: that it is possible to configure any amount of backend for manila, with different configurations that refer to distributed storages among different networks14:31
vponomaryovnicodemus_: but it is not scalable14:31
vponomaryovnicodemus_: and then use private share types14:32
vponomaryovnicodemus_: that refer to specific backend14:32
vponomaryoveach of them14:32
vponomaryovnicodemus_: so, if you have just several user groups that should be segmented - problem can be solved14:33
vponomaryovfor drivers that do not handle networking14:33
nicodemus_the case I'm researching has several options for backend, it could be 3PAR, or it could be Hitachi, possibly also let Cinder handle it14:34
nicodemus_So, depending on the backend that the end user decides to use, I would need to point out the networking constraints14:36
nicodemus_depending on their desicion14:36
vponomaryovCinder-based backend is restricted by openswitch14:49
vponomaryovnicodemus_: ^14:49
vponomaryovlinuxbridge is kind of supported, but it is not tested at all14:49
vponomaryovand very likely to be broken14:49
nicodemus_That's good to know, we always use openvswitch14:50

nicodemus_vponomaryov, if I may trouble you with one more question... Using Manila with a DHSS=True backend (cinder), does manila-share create a share instance on any compute node?16:40
vponomaryovnicodemus_: it is based on AZ: https://github.com/openstack/manila/blob/44990d0c/manila/common/config.py#L11616:42
vponomaryovhttps://github.com/openstack/manila/blob/a97983dd/manila/share/drivers/service_instance.py#L54316:43
nicodemus_Got it. So, manila-share would ask Nova to launch a share server from a configured image on that AZ, and nova-scheduler would then choose a compute node16:44
