| cyberde | Anyone experience with an active active setup for manila in 2 availability zones? | 10:08 |
| tbarron | cyberde: i'd be careful about running manila share service active-active if that's what you are talking about. But maybe elaborate a little on what you are trying to do ... | 10:19 |
| openstackgerrit | zhongjun proposed openstack/manila master: Add API document for share group https://review.openstack.org/490716 | 10:35 |
| cyberde | tbarron : For our openstack environment, we're looking to create workloads on different availability zones to establish an HA setup | 10:46 |
| cyberde | For this, you need to have the same data across these availability zones right? | 10:48 |
| tbarron | cyberde: so manila itself is essentially a set of control plane services, and | 10:51 |
| tbarron | these can be run in HA setups | 10:51 |
| tbarron | for example in our distro we run api, scheduler, and share services on controller nodes typically | 10:52 |
| tbarron | and run the api and scheduler services active-active behind haproxy | 10:52 |
| cyberde | That is HA within an availability zone, but across datacenters? | 10:53 |
| tbarron | but run the share service active/passive under packemaker control | 10:53 |
| tbarron | cyberde: then there is HA for the storage back end itself | 10:53 |
| tbarron | which is another thing | 10:53 |
| tbarron | cyberde: some back ends do replication for instance | 10:54 |
| tbarron | cyberde: right, we aren't doing it across datacenters | 10:54 |
| cyberde | yes, but if you have replication, you have the raw data on the other side but not available within that other openstack right? | 10:54 |
| tbarron | I'm just distinguishing the control plane HA from the back end data plane HA | 10:55 |
| tbarron | to clarify what you are asking about | 10:55 |
| tbarron | cyberde: different back ends do different kinds of replication types | 10:59 |
| tbarron | cyberde: https://docs.openstack.org/manila/latest/admin/shared-file-systems-share-replication.html | 10:59 |
| cyberde | tbarron: so you have drivers that actually updates manila on the other availability zone? | 10:59 |
| arnewiebalck | cyberde: your (Manila) database will run across the two data centers as well? | 11:00 |
| cyberde | arnewiebalck As I see it, you have 2 independent availability zones (aka openstack setups), and you use manila with a driver to connect to for example a glusterfs platform. | 11:01 |
| cyberde | You can replicate this glusterfs towards the different datacenter, sure. | 11:01 |
| cyberde | But I think the manila setups don't know about each other? | 11:01 |
| arnewiebalck | cyberde: yes, but that’s the backend, not the control plane | 11:02 |
| cyberde | arnewiebalck : So the control panel can inform the other openstack/manila service that a share is created and would also be available on the other side as a replica? | 11:02 |
| arnewiebalck | cyberde: I’m not clear on whether you plan to have two independent OpenStack deployments in two centers or a single one that spans two centers. | 11:03 |
| cyberde | A single that spans 2 datacenters is a bad idea in my point of view. You still have 1 availability zone, so also one spof. | 11:04 |
| arnewiebalck | cyberde: We run one Openstack deployment across two data centers with 5 AVZs :) | 11:05 |
| arnewiebalck | cyberde: But we do not have Manila HA across centers. | 11:05 |
| arnewiebalck | I have to tun, sorry, ttyl. | 11:06 |
| cyberde | arnewiebalck : So if you loose one DC, you will loose that manila service and no way to provide HA for your customers? | 11:06 |
| cyberde | Let us take AWS EFS for example. They replicate file systems across DCs/availability zones so you can have instances running in multiple AZs connecting to the same data. | 11:09 |
| tbarron | cyberde: I think several of the people you want to have this conversation work in US timezones. | 11:10 |
| tbarron | cyberde: also, manila PTG is this week. | 11:10 |
| tbarron | (I know, a week after the main PTG) | 11:10 |
| cyberde | PTG? | 11:12 |
| zhongjun | cyberde: https://etherpad.openstack.org/p/manila-ptg-queens | 11:12 |
| tbarron | cyberde: long story short, I don't think manila has what you are asking for today, but it would be good to explain your requirements to the manila community, perhaps by reference to AWS EFS | 11:12 |
| zhongjun | cyberde: :) PTG for manila itself | 11:12 |
| tbarron | zhongjun has a back end that can do replication :) | 11:12 |
| zhongjun | tbarron: yeah, huawei backend | 11:13 |
| cyberde | Interesting, I can believe a lot of vendors provide the replication. I'm just wondering how it would suddently end up at the other side where it also gets exposed to tenants. | 11:14 |
| cyberde | Anyway, will try to join this "PTG" thing and see if I can raise my question over there. | 11:14 |
| tbarron | cyberde: and distributed back ends like cephfs & glusterfs can span failure domains (with data protection at a different level) but | 11:15 |
| tbarron | the operation of manila itself across data centers as you are asking about is | 11:15 |
| tbarron | more the point I know | 11:15 |
| tbarron | cyberde: yeah, add the topic to the top of that etherpad | 11:16 |
| cyberde | Yes, I wonder how it is exposed on the other side. | 11:16 |
| cyberde | When is the PTG exactly? Because the when on the etherpad is a range. | 11:17 |
| *** toabctl has joined #openstack-manila | 11:17 | |
| tbarron | It goes on over two days, today and tomorrow, starting at 1300 UTC (convenient for US east coast) :P | 11:18 |
| tbarron | cyberde: bswartz is setting up the order of discussion but if you join he may be able to do your topic "early" today or tomorrow | 11:20 |
| tbarron | cyberde: more likely tomorrow I would guess since we've already set some topics for early today | 11:20 |
| cyberde | 1300 UTC, that is in 2 hours right? | 11:20 |
| tbarron | cyberde: approximately :) | 11:21 |
| tbarron | cyberde: what TZ are you? | 11:21 |
| cyberde | ah ok, would expected it to be a bigger difference, I'm European | 11:21 |
| tbarron | cyberde: it's a webex and he'll post the link in channel as well as on that etherpad | 11:21 |
| tbarron | really all one needs is the etherpad, a phone connection, and the irc channel | 11:22 |
| tbarron | I'm on linux and will connect to the webex link itself but that experience varies so I'll dial in as well | 11:23 |
| tbarron | cyberde: anyways, put your topic and irc nic in there after line 19 or so | 11:24 |
| zhongjun | cyberde: In my driver, we only support run share replica promote to end up at the other side where it also gets exposed to tenants | 11:28 |
| zhongjun | cyberde: Glad to see you in PTG | 11:28 |
| cyberde | Will add the following topic: "Manila replication (and NFS expose) across datacenters. Allowing an application to survive a single datacenter outage without any fuzz." | 11:29 |
| cyberde | Would assume that this would be a basic usecase on openstack... | 11:29 |
| tbarron | cyberde: cool, see you at PTG ! | 11:30 |

| openstackgerrit | morfy proposed openstack/python-manilaclient master: Fix for use endpoint_type in _discover_client method https://review.openstack.org/503006 | 11:39 |
| cyberde | Apparently I figured out that the type of replication share "writable" exists in manila, so the big question is, which vendor supports it aswel in their driver. | 11:51 |
| zhongjun | cyberde: I just saw netapp driver support it | 11:53 |
| cyberde | zhongjun : Checking | 11:54 |
| zhongjun | cyberde: May be you could get answer from bswartz, gouthamr | 11:55 |
| *** adrianofr has joined #openstack-manila | 12:02 | |
| cyberde | Seems that netapp driver is indeed the only driver that allows the share replication type: writable | 12:04 |

| arnewiebalck | cyberde: what users lose when we lose a DC is the ability to do share operations | 12:53 |
| cyberde | arnewiebalck hey, so what do you do if a customer wants to run his app in 2 DCs (preferably active/active) and needs access to the same files? | 12:54 |
| arnewiebalck | cyberde: they will still have a access to shares (if they are replicated) | 12:54 |
| cyberde | ow, which backend? | 12:54 |
| arnewiebalck | we use cephfs | 12:55 |
| arnewiebalck | I should have said “if they were replicated” ;) | 12:56 |
| cyberde | cephfs with replication and writable at 2 sides? | 12:56 |
| arnewiebalck | I don’t think CephFS supports that | 12:57 |
| cyberde | Neither do I | 12:57 |
| cyberde | Although that I think my simple usecase is valid though. | 12:58 |

| *** ganso has joined #openstack-manila | 12:59 | |
| arnewiebalck | cyberde: but as tbarron said, you need a backend that supports it (for the data) and have the whole Manila infra in HA as well (database, Rabbit, ...) | 12:59 |
| cyberde | arnewiebalck : It's "ok" if you would loose manila, as long as you don't loose the shares. | 13:00 |
| arnewiebalck | cyberde: exactly | 13:00 |
| arnewiebalck | cyberde: we don’t offer this atm, but leave this to the application ;) | 13:01 |
| cyberde | Manila still needs to set it up I guess. On both sides. | 13:02 |
| *** catintheroof has joined #openstack-manila | 13:02 | |
| arnewiebalck | cyberde: i.e. using backends in the two DCs and make sure the data is stored on both | 13:02 |
| cyberde | arnewiebalck Yes, that is one layer | 13:02 |
| cyberde | The other layer is that Manila needs to replicate the configuration for the exports I guess | 13:02 |
