bswartzcsaba: pong16:43
csababswartz: I just became aware of this: http://eavesdrop.openstack.org/meetings/manila/2015/manila.2015-02-26-15.00.log.html. "#topic DB access in the share drivers"16:48
bswartzyes16:48
csabaproblem is in gluster-native we use the db to maintain the association between shares and gluster volumes16:49
bswartzcsaba: there is a plan to fix that16:49
bswartznot specific to gluster, but a general solution to help drivers map shares to what really exists on the backend16:50
bswartzit will allows drivers to store that mapping in the DB without directly accessing the DB16:50
csabaso until that comes to being, is it OK to use the db as being done now?16:50
bswartzyes it's a longer term problem16:51
bswartzwe're not going to do anything drastic in the short term16:51
bswartzbut when we see DB accesses in the drivers we're going to file bugs and figure out a way to replace them with something we can support16:51
*** openstackgerrit has quit IRC16:54
csabaalso, in gluster-native patch that implements {create,delete}_snapshot (https://review.openstack.org/164543)  I got scolded for using the db to find the share of the snapshot  -- is there a better way there?16:54
*** openstackgerrit has joined #openstack-manila16:54
*** mtanino has joined #openstack-manila16:59
csababswartz: (sorry to nag you, I'm just repeating the question because missed addressing to you):  also, in gluster-native patch that implements {create,delete}_snapshot (https://review.openstack.org/164543)  I got scolded for using the db to find the share of the snapshot  -- is there a better way there?17:08
bswartzcsaba: you can just do something like this if you want to point someone's attention to a previous comment17:09
bswartzcsaba: ^17:09
csababswartz: cool I missed that idiom17:10
bswartzso why do you need the DB here17:10
bswartzthe snapshot object should contain a reference to its parent share17:11
bswartzwhat value are you not able to obtain?17:11
csabashare.export_location is how we map share to gluster_volume17:12
csabawe have snapshot["share_id"], so we get the share data via id from the db17:12
bswartzso you just need that export location?17:13
csabayep17:13
bswartzyeah I think those are related problems17:13
bswartzwe need to fix that up in the manager level17:14
bswartzare you available to help with that?17:14
csabasure17:14
csabait needs some discussion I guess...17:15
bswartzyes17:15
bswartzthere's not enough time in liberty unfortunately17:15
bswartzerr in kilo17:15
bswartzthis will be a liberty priority17:16
csabaOK17:16
csabaso for now, I'll just go on and use the db...17:16
csababswartz: is that OK?17:17
bswartzI think so17:17
bswartzas long as you can commit to fixing it after the better method comes along17:17
bswartzI would put some FIXMEs in the code17:18
bswartzwith an explanation that you're waiting until the manager is changed before you can do the right thing17:18
csabasound fine!17:18

lpabonhi all, devstack question again.  in 'devstack/README.rst' it just says to add one line to local.conf, but in https://wiki.openstack.org/wiki/Manila/KiloDevstack shows more options with neutron... are both correct?18:02
*** rushil_ has joined #openstack-manila18:09
*** sgotliv has quit IRC18:16
bswartzlpabon: neutron is needed for the generic driver (unless you're using n-net), however it's not strictly required anymore18:17
lpabonbswartz: ok, so if i want to setup a VM with the generic driver, i should follow the wiki instructions?18:18
bswartzyeah they should work18:18
lpaboni probably need to enable cinder in the local.conf file also, right?18:18
*** timcl1 has joined #openstack-manila18:29
bswartzlpabon: for the generic driver, cinder and neutron are requirements, yes18:29
bswartzand then either n-net or neutron18:29

csabaxyang1, xyang_ : ping21:58
xyang1csaba: Pong21:58
csabaxyang1: hi21:59
csabaI have a question about your review comment https://review.openstack.org/#/c/164543/1/manila/share/drivers/glusterfs_native.py,unified21:59
xyang1Sure22:00
xyang1Which one22:00
csabawhereby you say: "Also 'export_location' is no longer a column name in shares table. It is changed by the following patch: <patch url>"22:00
xyang1There is db schema change22:01
csabahowever, in that patch https://review.openstack.org/#/c/159927/12/manila/db/sqlalchemy/models.py,unified line 17922:01
csabaexport_location is defined as a property22:01
xyang1It was removed22:01
csabaah22:01
xyang1Oh, you are saying there is still a property22:02
csabayes22:02
xyang1Ok, so you can get it as a property then22:03
csabaxyang1: also, wrt db access from driver, I had a discusson about it with Ben earlier the day -- we concluded it's OK to use db until manager grows up to relax the need for it22:04
csaba(he just asked me to add a FIXME note about it)22:04
xyang1Sure, that is fine with me22:04
xyang1Ok22:04
*** Maike has quit IRC22:05
*** echoingumesh has joined #openstack-manila22:06
csabaxyang1: and wrt blueprint registry -- is it OK to add a blueprint so late in Kilo-3? If there is no reason to do otherwise, I'd like to get this patch in into Kilo-3, and my understanding was that small feature patches (for some definition of small) might get it w/o BP22:07
xyang1csaba: Check with Ben.   If he is ok, I am fine22:08
csabaxyang1: yes I talked with him earlier22:09
xyang1csaba: Ok, then you are all set22:09
csabaxyang1: thanks for your help!22:10
