| zengyingzhe_ | gouthamr, hi you there? | 01:38 |
| gouthamr | zengyingzhe_: hi, yes | 01:38 |
| zengyingzhe_ | I got a question about replication. | 01:38 |
| gouthamr | zengyingzhe_: sure.. | 01:39 |
| zengyingzhe_ | does the active replica allow to extend/shrink from the replication feature design? | 01:40 |
| gouthamr | zengyingzhe_: yes.. | 01:40 |
| gouthamr | zengyingzhe_: according to manila, all share instances of a given share must be of the same size.. (size is hence a property of the share and not the instance) | 01:41 |
| gouthamr | zengyingzhe_: https://github.com/openstack/manila/blob/master/manila_tempest_tests/tests/api/admin/test_replication_actions.py#L71 | 01:42 |
| zengyingzhe_ | gouthamr: Ah, looks like it's a problem for huawei driver, cause it doesn't handle this situation while a share has replicas. | 01:42 |
| gouthamr | zengyingzhe_: oh... | 01:43 |
| gouthamr | zengyingzhe_: is your CI now capable of running those tests? | 01:43 |
| zengyingzhe_ | gouthamr: CI can pass. Actually the extend/shrink operation can successd. The problem is that the driver doesn't apply these operations to all related replicas of one share. | 01:47 |
| gouthamr | zengyingzhe_: oh.. sounds like a bug then.. :) | 01:48 |
| *** kaisers__ has joined #openstack-manila | 01:49 | |
| zengyingzhe_ | gouthamr: Yep, I'll take care of it. | 01:49 |
| gouthamr | zengyingzhe_: +1 | 01:50 |
| zengyingzhe_ | gouthamr: thanks for your help. | 01:50 |

| TommyLikeHu | hey guys, How to run a single unit testcase in manilaclient with tox? | 02:10 |
| *** mtanino has quit IRC | 02:12 | |
| gouthamr | TommyLikeHu: tox -epy27 -- test_xyz | 02:16 |
| TommyLikeHu | gouthamr:thanks | 02:17 |
| gouthamr | np.. | 02:17 |
| TommyLikeHu | gouthamr: can I see the detail output with --debug something like that? | 02:19 |
| gouthamr | TommyLikeHu: python-manilaclient directly uses testr to run its tests.. | 02:28 |
| gouthamr | TommyLikeHu: so, i'm not sure how you can write to stdout and stuff | 02:28 |
| gouthamr | TommyLikeHu: however, if you make a slight change to your tox.ini, you can get that to work | 02:28 |
| gouthamr | in the [testenv] section, replace "python setup.py testr --testr-args='{posargs}'" with ostestr {posargs}" | 02:29 |
| gouthamr | TommyLikeHu: ostestr {posargs} | 02:29 |
| gouthamr | TommyLikeHu: then you can run your tests like this: "tox -epy27 -- --regex=test_xyz" | 02:30 |
| TommyLikeHu | gouthamr: thanks, l'd like to have a try | 02:33 |
| gouthamr | TommyLikeHu: you're welcome | 02:33 |

| *** StraubTW has joined #openstack-manila | 13:15 | |
| rajiv_ | tharron: is my understanding correct? We have ceph cluster with cephFS. Then VMs are put in the public network of ceph cluster so that VMs can directly contact ceph for mounting file system. Therefore guest OS should have ceph client installed. And quota feature is given at client side, which can be compromised and because ceph cluster is also accessible from the VMs. | 13:16 |
| rajiv_ | rraja: thanks | 13:16 |
| *** tpsilva has joined #openstack-manila | 13:16 | |
| *** bhagyashri_s has joined #openstack-manila | 13:17 | |
| tbarron | rajiv_: current native cephfs driver is the first step; the preso rraja just gave you shows roadmap for mediating access to the cluster from client, etc. | 13:19 |
| *** mliima has joined #openstack-manila | 13:20 | |
| rraja | rajiv_: the clients need `ceph-fuse` to be able to mount cephfs and respect share sizes (done by setting quotas on CephFS shares), since only the fuse client has quota support. | 13:21 |
| rajiv_ | rraja: what about kernel ceph client? does not it support quota? | 13:22 |
| rraja | rajiv_: it does not. | 13:22 |
| rraja | rajiv_: as you mention the clients are expected to well behaved. see http://docs.ceph.com/docs/master/cephfs/quota/#limitations | 13:23 |

| *** rajiv_ has quit IRC | 13:24 | |

| tinwood | hi, may I ask a quick question about where the generic driver tries to launch an instance? It seems to be on the same machine as the manila-share service? | 13:55 |
| vponomaryov | tinwood: it is completely up-to-nova | 13:58 |
| tinwood | vponomaryov, That's what I would have thought; which is weird as the "manila show" says the host is the same as the manila-share which isn't a nova-compute. | 13:59 |
| tinwood | vponomaryov, also is there a way to delete a share in the "error_deleting" status? | 14:00 |
| *** eharney has joined #openstack-manila | 14:02 | |
| gouthamr | tinwood: that's a tricky question, was the nova instance created? was the cinder volume created? where did the driver blow up? if you can clean up those resources on your own, there's `$ manila force-delete xyzzy` | 14:03 |
| *** cknight has joined #openstack-manila | 14:04 | |
| tinwood | gouthamr, it's a virtual openstack so I can tear it down if I need to. Just wanted to clean the share out so I can try again? I think I didn't have enough memory on my compute to launch the share instance so I'm going to re-provision those and try again. | 14:05 |
| gouthamr | tinwood: if your share ended up with 'error_deleting' and you want manila to attempt, but delete it anyway if the deletion fails on teh backend, use 'force-delete' | 14:06 |
| * gouthamr heh, no joke about using the force yet. | 14:06 | |

| vponomaryov | bhagyashri_s: hello | 14:09 |
| bhagyashri_s | vponomaryov: Hi, basically the the module in which I have made changes is used for the test purpose only so IMO there is no need to test the change. I have made change just for the code optimization and refactoring. | 14:12 |
| vponomaryov | bhagyashri_s: it is not executed by test run | 14:13 |
| vponomaryov | bhagyashri_s: it is the point | 14:13 |
| vponomaryov | bhagyashri_s: looks like you change dead code | 14:13 |
| vponomaryov | bhagyashri_s: then sane question, why do you do this? | 14:14 |
| *** absubram has joined #openstack-manila | 14:14 | |

| vponomaryov | bhagyashri_s: first of all, it is not optimization, amount of operations there is kind of the same. Second, deletion of dead code is better then its reqriting | 14:21 |
| vponomaryov | s/then its reqriting/than its rewriting/ | 14:22 |

| tongli | good day to Manila guys. setting up devstack with manila enabled. Also have the UI show on horizon. saw generic1 and generic2 in manila.conf file. | 15:33 |
| tongli | but can not really create a share. can someone help on what I am missing? | 15:33 |
| tongli | there is a admin_net created. but I can not really boot up a VM on that network with the manila-service-image-master. | 15:34 |
| *** dsariel has quit IRC | 15:35 | |

| *** rhagarty has joined #openstack-manila | 15:37 | |
| bswartz | vponomaryov: how hard would it be to change devstack plugin to default to LVM driver instead of generic driver? | 15:39 |
| bswartz | vponomaryov: if we do that it might help ppl like tongli | 15:39 |
| vponomaryov | bswartz: easy to change default, but we depend on that default in some places | 15:39 |
| bswartz | vponomaryov: what places? (this is why I'm asking) | 15:40 |
| tongli | @bswartz, +100. | 15:40 |
| vponomaryov | bswartz; for example - currect grenade job | 15:40 |
| tongli | I had to change some code also enable it in horizon. | 15:40 |
| tongli | like adding this line. | 15:40 |
| vponomaryov | bswartz: I created commits for switching it to dummy driver, but it is not merged yet | 15:40 |
| *** ganso has left #openstack-manila | 15:40 | |
| tongli | HORIZON_CONFIG["customization_module"]="manila_ui.overrides" | 15:41 |
| gouthamr | fwiw, the LVM instructions finally showed up in the newton install guide :) http://docs.openstack.org/project-install-guide/shared-file-systems/newton/ | 15:41 |
| tongli | without that line in local_settings.py, horizons has nothing to do with manila | 15:41 |
| bswartz | vponomaryov: let's make sure nothing depends on the default driver that devstack sets | 15:41 |
| bswartz | tongli: that shouldn't be needed anymore... | 15:42 |
| bswartz | I thought that horizon fixed the way plugin were installed | 15:42 |
| tongli | @bswartz, if I do not have that in the local_settings.py, horizon won't show "Share" tab. | 15:42 |
| vponomaryov | tongli: what release of openstack do you use? | 15:43 |
| tongli | I tested with newton release. | 15:43 |
| tongli | newton, not the latest master. | 15:43 |
| tongli | not sure how much different though. | 15:43 |
| bswartz | tongli: newton from git? or rpms/debs? | 15:43 |
| bswartz | oh nm you said devstack | 15:44 |
| bswartz | devstack will pull from git | 15:44 |
| tongli | @bswartz, this is devstack install on ubuntu. | 15:44 |
| tongli | right. | 15:44 |
| tongli | after devstack install, things look ok. I saw generic1 and generic2 in manila.conf file, | 15:45 |
| tongli | and also admin_net got created. | 15:45 |
| tongli | I thought the plugin has some script to also create vm using manila-service-image-master. | 15:45 |
| tongli | but that did not happen. no vm was running after devstack finished. | 15:46 |
| vponomaryov | tongli: traces in logs? how did you run share creation? | 15:46 |
| vponomaryov | tongli: have you looked at docs? | 15:46 |
| tongli | I use the horizon UI to create share. | 15:47 |
| tongli | yes, I did look at all the docs I can find, at the state of devstack, I do not really know what to do. | 15:47 |
| tongli | since the configuration seems already done. | 15:47 |
| tongli | I assume generic1 and generic2 are share nodes (in manila.conf file). | 15:48 |
| vponomaryov | tongli: and you configured share-network correctly right? | 15:48 |
| tongli | but I am not seeing a vm created. | 15:48 |
| tongli | yeah, I can create manila share network fine. | 15:48 |
| tongli | since I already have a tenant neutron network. | 15:48 |
| vponomaryov | tongli: what does it contain? | 15:48 |
| tongli | that part is ok. | 15:48 |
| vponomaryov | tongi: what do you see in logs of manila? | 15:49 |
| vponomaryov | tongli; we cannot help you not having even traces | 15:49 |
| tongli | ERROR manila.share.manager [req-7df6d64e-cace-4b73-91ee-a3b8f6f1846c 25dbea24318e4f9f9e7cc963c9e5a98c be7de805594d49ca8c18b15a36333aa3] Creation of share instance d1b0bd1e-053a-4712-86a7-e2dfcfff1664 failed: failed to get share server. | 15:49 |
| vponomaryov | tongli: it is not trace | 15:49 |
| tongli | that is the stuff I can find in the log files. | 15:50 |
| tongli | I can change the log level to trace and try again. | 15:50 |
| vponomaryov | tongli: and it is recommended to use "paste" sites for traces and code | 15:50 |
| tongli | give me a second. | 15:50 |
| tongli | yes | 15:50 |
| tongli | I will use that. | 15:51 |
| tongli | can I ask you if I really need to have a VM (using the manila-service-image-master image) running to have all the stuff working? | 15:52 |
| tongli | or manila actually will provision a VM automatically? that is what is puzzling me. | 15:52 |
| tongli | devstack seems trying to do something but not complete. | 15:53 |
| tongli | if I manually start up a VM using that image, how does manila know that vm is a manila shared node. | 15:54 |
| tongli | if you can help answer these few questions, that will be very helpful. | 15:54 |
| tongli | @vponomaryoy @bswartz ? | 15:55 |
| bswartz | tongli: the generic driver has a bunch of requirements | 15:56 |
| bswartz | you need nova setup properly, you need cinder setup properly, and you need that service image | 15:56 |
| bswartz | also you need glance/neutron | 15:56 |
| bswartz | it's way easier to setup the lvm driver | 15:56 |
| tongli | so I assume that devstack plugin was trying to do that but half way through? | 15:57 |
| tongli | just need to confirm. | 15:57 |
| bswartz | the devstack plugin configures the generic driver by default | 15:58 |
| bswartz | you need to modify you local.conf file if you want something else | 15:58 |
| tongli | since things are not working, you always wonder if you did something wrong like mising some configuration or you have to do some thing extra like create a VM. | 15:58 |
| tongli | @bawartz, that is cool. have a sample or something to use lvm? | 15:59 |
| bswartz | you don't need to create anything special, but you do need the environment setup with all the dependencies | 15:59 |
| tongli | I mean few samples code for local.conf to use lvm? | 15:59 |

| openstackgerrit | Merged openstack/manila: NetApp cDOT driver should not report untenable pools https://review.openstack.org/385594 | 17:17 |
| tongli | @bswartz, created a share, and it seems working. thanks for your help. | 17:17 |
| tongli | after I created a share, a lvm appeared when I did lvdisplay. | 17:18 |
| tongli | after I deleted the share, the lvm disappeared when I did lvdisplay. so I think that means manila is working in my little devstack env. | 17:18 |

| tongli | after I created the share, I simply just need to mount it from any vm that I like to, right? | 18:09 |
| tongli | since this is really just a NFS share, correct? | 18:09 |
| bswartz | tongli: yeah the trick is network connectivity and access control | 18:15 |
| bswartz | VMs typically cannot route packets to the hypervisor they're on unless you create a provider net or use floating IPs | 18:15 |
| tongli | understand. allow nfs port to go through. | 18:15 |
| tongli | right. | 18:16 |
| bswartz | and the NFS server will see the source address as the floating IP in that case, which means when you do access-allow you need to allow access to the floating IP not the private IP | 18:16 |
| tongli | totally. understand that part. thanks again. | 18:16 |
| bswartz | or just use 0.0.0.0/0 | 18:16 |
| tongli | yes. wanted to confirm with you first. | 18:17 |
