gouthamrtbarron: Ignazio Cassano's request from the mailing list sounds like a problem that share replication can solve17:35
gouthamrtbarron: although it isn't what we "support"17:35
gouthamri mean, he'll need to setup the backend from site B into site A and create replicas17:38

tbarrongouthamr: replication can make his share from installation a show up on installation b19:00
tbarrongouthamr: back end replication19:01
tbarrongouthamr: then he can unmanage19:01
tbarronpromote19:01
tbarronvia back end19:01
tbarronand manage on installation b19:01
tbarronthis is assuming his use case is two separate installations , not some kind of federated openstack19:02
tbarrongouthamr: but if he wants to manage from both installations via openstack/manila then they better somehow not be totally "two" installations19:02
tbarrongouthamr: else split brain19:03
tbarrongouthamr: not sure what he really wants to do yet though19:03
tbarrongouthamr: if you are, then please propose the solution on the thread19:03
tbarrongouthamr: oh I see his reply19:08
*** luizbag has quit IRC19:09
tbarrongouthamr: there's no split brain but neither is there a brain transplant or brain replication, do you agree?19:10
tbarrongouthamr: he can get the data over to B, he can manage it from there, but there's no solution to get the manila, neutron, keystone DBs over19:11
tbarrongouthamr: no solution meaning that OpenStack doesn't provide a way to do that19:11
*** e0ne has joined #openstack-manila19:29
gouthamrtrue, brain transplant situation :)19:38
gouthamri *may* have a solution, still noodling it19:39
tbarrongouthamr: i'll go on and make my brain transplant remark and then you can come in and say how to do it if you want20:03
gouthamrtbarron: i was going to refer them to ntap20:03
*** erlon__ has quit IRC20:03
tbarrongouthamr: how is ntap going to get their keystone info from A to B?20:04
gouthamrtbarron: he just wants the shares over20:04
tbarrongouthamr: ntap is a back end20:04
tbarrongouthamr: not as I understood it20:04
tbarrongouthamr: but I may be confused20:04
* tbarron looks at the thread again20:05
gouthamrtbarron: http://lists.openstack.org/pipermail/openstack-discuss/2019-February/002429.html20:06
tbarrongouthamr: "I must modify the manila db on B?"  not just to discover the data and the ntap attributes but yes if you want the openstack attributes, right?20:07
tbarroncan do replication under A with both filers, promote to ntap B, unmanage from openstack A, manage from openstack B if all he wants is data and ntap attributes20:08
tbarronjust getting manila to set up snapmirror for him, basically20:08
gouthamrtbarron: yes, but a few things need to be considered20:09
gouthamrtbarron: replicas can't be "managed"20:09
tbarrongouthamr so he has to break the replication relationship20:09
gouthamrtbarron: i.e, if you have a share that can't be written to, or has a replication relationship, it can't be managed20:09
gouthamrtbarron: yes20:09
tbarrongouthamr: be a lot easier just to skip manila replication and unmanage, use ntap management to replicate & break, then manage from B20:10
tbarrongouthamr: unless you can easily break the relationship without having to do ontap cmds I don't see any advantage to doing it with manila20:10
gouthamrtbarron: well there is some hardening that manila will do20:11
gouthamrtbarron: but yes, if the guy's familiar with netapp, they can do the same things on their end20:11
gouthamrtbarron: i'd like to know if he's using replication right now20:13
tbarrongouthamr: my point is unless manila cmds will do it all then he'll have to involve a netapp admin (maybe himself) in the process20:13
*** jmlowe has quit IRC20:13
gouthamrtbarron: hmmm, if i understand it correctly, if he's already replicated his shares with manila and wants to now "move" them to a different OpenStack, it is straightforward20:15
gouthamrtbarron: promote secondaries, delete old primaries, unmanage all on OpenStack A20:15
gouthamrtbarron: then manage everything on OpenStack B20:15
tbarrongouthamr: yeah, I just want to make sure he only cares about the data and netapp attributes20:16
tbarrongouthamr: sent my worry-wort mail, you can tell him what to do next (even if it's call ntap)20:16
tbarrongouthamr: if he had offsite CSI snapshots he could put them on tape, put the tapes in a truck, drive to installation B, create vols from snaps20:17
gouthamrtbarron: or call ganso20:18

tbarrongouthamr: thanks much for updating the active-active section of https://wiki.openstack.org/wiki/Manila/SteinCycle !21:22
tbarronamito: when you get a chance pls. take a look at opestack sdk section there and put in a couple notes21:23
amitotbarron: np, i'll do that tomorrow21:23
tbarronamito: thanks!21:23
tbarronganso: yours is marked yellow atm b/c if there's one huge big patch right before M3 then it will go to t21:24
tbarronTrain21:24
amitotbarron: I have a small beta... for now it's only for the Share object and the Share detail API. I'm swamped with downstream non-openstack work and haven't got much time for it lately :(. I hope I'll get to it in the weekend and upload a patch finally.21:26
tbarronamito: that's great, thanks!21:27
tbarronwe should have cinder mid-cycles so we get e0ne's help more often21:28
* tbarron notices he's gone, will express his appreciation again in a more TZ appropriate manner21:28
