ameadezhongjun_: hey14:15
zhongjun_ameade: hi, I saw your user message code. Does the driver can use your function to create a user message?14:16
ameadezhongjun_: yeah, it's probably better if the driver raises a specific message up to the manager and have the manager create the message14:18
bswartzzhongjun_: users are not supposed to know anything about the backend and if the backend were emitting specific messages it could break that abstratction14:19
bswartzzhongjun_: I agree with ameade that the manager should be sending the messages and the driver might trigger that through a well-known exception14:19

bswartztbarron: yes that should be something admins can do16:00
bswartztbarron: but the question is what mechanism16:01
* gouthamr gets his lunch to this meeting16:01
vponomaryovDaiDV: cinder provides "block" storage, manila provides "share file systems"16:01
tbarronso, #2 is admins turn off the 'make visible for all' checkbox.16:01
bswartzgouthamr: you should have had breakfast16:01
tbarronbswartz: that's what you just agreed to, right?16:01
gouthamrhaha.. i eat, a lot16:01
vponomaryovtbarron: it is ok to let admins to disable it16:01
gansotbarron: isn't that box only for admins anyway?16:01
bswartzganso: no we've supported user-create public shares for a long time16:02
gansobswartz: O_O16:02
bswartzcreated16:02
vponomaryovganso: =)16:02
gansobswartz: sounds fundamentally wrong16:02
vponomaryovganso: no16:02
bswartzganso: all it means is that other tenant can see the share in the REST API16:02
vponomaryovganso: I am, as user may want to sahre my share to all in the world as readonly16:02
bswartzthey can't modify it or necessarily access it -- that's up to the owner of the share16:02
*** marcusvrn_ has quit IRC16:03
gansooh I see, glad they need access. that would be terrible for volumes16:03
bswartzthere's an ergonomics problem with listing of public shares -- potentially the list could be huge so you need a way to hide them16:03
*** gouthamr|2 has joined #openstack-manila16:04
bswartzI think that you only see public shares if you ask to see them though, right?"16:04
gansobswartz: yes, if everyone shares their share (pun intended), then people end up seeing what they don't want to see16:04
bswartzbut to address tbarron's problem -- we need to make sure that there's a policy mechanism to prevent creation of public shares16:04
bswartzand ideally it should be easy to turn off the UI for it too16:05
tbarronso sgotliv will be posting some patches on these two subjects real soon now16:05
bswartzdo we have a config file for manila-ui?16:05
gansobswartz: oh so tbarron wants to remove the capability, not the visibility16:05
tbarronvisibility and capability when admin sets config/policy appropriately16:06
bswartzyes he wants to give admins a switch they can use to flip off the public share functionality16:06
markstur__wants the UI to not show things the users shouldn't see16:06
tbarronyeah, you can see why cloud admins would want this kind of thing.16:07
bswartzhopefully there's a place we can stick a config flag in the UI plugin and the code can just hide that checkbox16:07
tbarronso we'll have some patches to meet actual short term customer needs16:07
bswartzI don't hear any objection to making the UI customizable in this way16:07
bswartztbarron: sounds like you're good to go16:07
tbarronwe'd like to land them in a timely manner and at the same time think through arch issues for longer term if they come up16:07
bswartzDaiDV: okay the meeting is over how can I help?16:08
tbarronbswartz: ty!16:08
DaiDVOk, I just try to install opensack mitala, and I see option2 : manila with driver.16:09
bswartzDaiDV: regarding cinder and manila -- initially we intended for there to be one project that handled both block storage and share file system storage, however the two types of storage a different enough that we decided it would be more productive to fork the cinder project and start a new project called manila for shared file systems16:09
bswartztbarron: apologies for not ensuring that topic was first in the agenda -- I forgot about sgotliv's timezone issues16:10
bswartzI should have broken that out into its own agenda item16:11
*** markstur__ has left #openstack-manila16:11
tbarronbswartz: not a problem, i appreciate you thinking of us though16:12
*** nkrinner has quit IRC16:12
bswartztbarron: the problem was I didn't think -- if I had I would have done it differently16:12
*** nkrinner has joined #openstack-manila16:12
*** nkrinner is now known as nkrinner_afk16:12
bswartzDaiDV: I don't understand if you're trying to deploy openstack or if you're a developer trying to write a driver16:13
DaiDVbswartz, I just try to deploy openstack.16:13
DaiDVbswartz, But if we not consider share a share/volume to multi instances, manila can do anything else that different with cinder?16:14
bswartzDaiDV: then for you it's a question of what type of storage you want for your applications16:14
bswartzDaiDV: there are fundamental differences between block storage and shared file systems16:15
bswartzone in particular is that block storage can be used by at most a single instance whereas shared file systems can be mounted by as many instances as you like16:15
bswartzalso, block storage is just a virtual disk which you can format with any filesystem and use inside your OS -- shared file systems rely on network filesystem protocols like NFS or CIFS/SMB16:16
bswartzalso the network connectivity for the two types of storage is dramatically different -- block storage is all hidden underneath the hypervisor and shared file system storage goes completely around the hypervisor, requiring the VM to have a network path to the storage16:19
bswartzI hope that helps -- I'm late to my next appointment and will bbl16:19
DaiDVmany thanks.16:20
DaiDVI just have a new thing: In future, we can share a Share Instance on multi-cloud and cinder is not allow its! Is right?16:22
*** absubram has quit IRC16:31
*** akshai has quit IRC16:40
bswartzwell both cinder and manila could be used independently of openstack -- so in that sense sharing across clouds is not impossible16:44
bswartzhowever cinder works best in conjunction with nova providing storage for a single cloud16:45
bswartzmanila shares can be access by anything which has a network path to the share16:45
*** xyang_ has quit IRC16:45
bswartzs/acccess/accessed/16:45
bswartzso in practice is probably a lot easier to share data between clouds with something like manila -- although you'd be on you own to figure out the networking part of that16:46
