MVenesio@Reepicheep @bswartz It is for testing, but it is a test to move the service into production next month, I've a big ceph cluster and cinder already working. So, talking about production environments, what do you think about the ganesha driver ? anyone tested it ?12:45
openstackgerritOpenStack Proposal Bot proposed openstack/manila-ui master: Updated from global requirements  https://review.openstack.org/46526312:47
MVenesio@Reepicheep @bswartz I know that the generic driver doe not have HA between nfs instances but as bswartz said at least all data is safe on ceph. So i'm thinking that the generic driver is the best approach that i can use, to provide nfs and cifs services in my cloud. Unless ganesha driver works well and i can use it with ceph.12:48

MVenesiobswartz: this one  --> https://docs.openstack.org/developer/manila/devref/ganesha.html16:07
bswartzMVenesio: it's not a proper driver, but a mixin16:16
bswartza library for other drivers to use16:16
smcginnisbswartz: FYI, we have been getting py27 failures that apprear to be somehow related to tooz with filesystem locks.16:18
smcginnisbswartz: Just a warning since Manila is set up the same way.16:19
*** catintheroof has joined #openstack-manila16:19
smcginnisbswartz: This gets around it, but I think there is still an issue there in the filesystem driver for tooz: https://review.openstack.org/46599816:19
bswartzsmcginnis: can't we just drop p2.7 already?16:26
smcginnisbswartz: Hah! That was my initial thought too. :)16:26
bswartzI would love to delete all the six crap in the code16:26
smcginnisWe'll have a lot of good clean up when that day finally comes.16:27
bswartzsmcginnis: so why allow filesystem locks at all?16:27
bswartzthe power of tooz comes when you use something better than filesystem locks16:28
smcginnisbswartz: Right. But if you don't need distributed locking, we didn't want to require the setup of zookeeper or anything.16:28
smcginnisbswartz: So defaulting to filesystem kept the pre-DLM behavior of local FS locks.16:28
bswartzetcd appears to be the chosen one16:29
smcginnisbswartz: And if they actually need DLM, then they can set it up.16:29
smcginnisbswartz: Yep, now that we are going to make etcd a core service in OS, we can switch that.16:29
bswartzthere's a ton of hate for zookeeper16:29
smcginnisbswartz: But we're not there yet.16:29
smcginnisDarn Java.16:29
bswartzindeed16:29
MVenesiobswartz: exactly, but taking into account that ganesha has ceph integration, its an HA system, and provides NFS access, i think its a good option to use. On the other side it does not support multitenant networks isolation, and despite the HA feature, its a single point of failure for the system. So for that reason my question is, if the generic driver its ready for production, in your opinion.16:30
bswartzMVenesio: yeah there are a lot of arguments in favor of ganesha -- but we don't support it yet16:30
bswartzthere are 2 commercial drivers that support it16:31
bswartzbut nobody has stepped forward to make sure ganesha works properly as a first party driver16:31
*** jmlowe has quit IRC16:33
MVenesiobswartz: ok and if you have to choose an opensource driver for manila in a production environment, which do you choose ?16:34
bswartzMVenesio: generic is the oldest and best tested driver16:35
MVenesiobswartz: perfect, that's the answer. So i'll be testing it in the next days16:37
MVenesiobswartz: thanks for your help16:37
bswartzsure thing16:37

MVenesiobswartz: I've installed and configured manila in my environment using the generic driver, i'm trying to create a new share and i'm getting this error : BridgeDoesNotExist: Bridge br-int does not exist.18:19
MVenesiobswartz: So i've installed neutron-plugin-linuxbridge-agent  on the manila node but it's not pretty clear which is the function of that plugin on the manila node or how i've to configure it18:20
bswartzMVenesio: is the manila-share service on the same host as neutron-l3-agent?18:20
MVenesiobswartz: No, its a separated instance18:20
bswartzwe test with ovs not linuxbridge btw18:21
bswartzalthough IIRC linuxbridge should work18:21
bswartzthey have to be on the same host18:21
bswartzit's one of the many limitation of the generic driver18:21
MVenesiobswartz: perfect i'm using ovs in all my setup also18:21
MVenesiook so to use ovs, should i've to instal manila-share on my network node ?18:22
bswartzMVenesio: yes18:23
bswartzone of the things the generic driver does is create a port on the OVS bridge for itself so it can SSH to the nova instances even while those nova instances are on other networks18:24
bswartzwe need to look at using a more supported approach (this is a hack) but it's worked well for years18:25
MVenesiobswartz: i thought that was like murano, using and agent and receiving instructions via rpc18:26
MVenesiobswartz: so do i've to configure something in the manila.conf to use ovs instead linuxbridges ?18:27
bswartzthe driver talks to the "service instances" over SSH18:27
bswartzthat's shouldn't be necessary18:27
MVenesiobswartz: i see, ok i'll test it in the network node, Thanks18:27
