Amit_Hello Team ,   I tried installing Manila from the following link :  https://wiki.openstack.org/wiki/Manila/KiloDevstack  However, the Devstack installation completes , but the Manils Module fails to get installated. I cannot see any folder with Manila under /opt/stack/. Secondly , not sure if this is a network issue and just for precaution I have commented and changed  the "GIT_BASE=${GIT_BASE:-git://git.openstack.org}" to "G05:20

MaikeHi, im using Ubuntu 14.04 with devstack (master) also manila is actual (I cloned it yesterday). If I run 'manila create' I get the following error from the scheduler: 'NoneType' object has no attribute 'get' .. Is that a known error?06:44

ganso_hello guys, quick question: If I am running a code in driver.py base class, and need to call "allow_access", I suppose the correct way is to call API, so it registers the rule in db and perform all checks. So far I have only seen driver.py calling rpcapi (in Cinder as example), which will enter manager.py allow_access method, not API's. What would be the17:24
ganso_correct approach here?17:24

bswartzwhy do you need to do that18:12
openstackgerritMark Sturdevant proposed openstack/manila: HP 3PAR driver documentation  https://review.openstack.org/16457518:14
*** lpetrut has joined #openstack-manila18:17
ganso_bswartz: because the approach we discussed is that manila node would mount the shares and copy data from one to the other. So the share needs to allow access to manila node ip.18:17
*** akerr has quit IRC18:17
bswartzif it's for your own backend, can't you just call the internal function rather than going through the RPC layer?18:18
ganso_bswartz: yes, that is what I am doing right now, I was unsure if it was a good approach18:19
bswartzdo you have a patchset I can look at18:20
ganso_bswartz: but that will not for if the backend is not the same, but the share in the other backend is reachable by manila node18:20
ganso_bswartz: not yet18:20
bswartzI think you should call the internal method18:21
*** akerr has joined #openstack-manila18:22
*** markstur has joined #openstack-manila18:22
*** vbellur has quit IRC18:23
ganso_bswartz: but if the same manila node has two backends registered, and it can access shares from both backends, shouldn't I be able to migrate from one to the other? the only way to send the allow_access command to the other is through RPCAPI18:26
ganso_bswartz: the migration call is triggered and handled by backend1, but it interacts with backend218:26
bswartzmigration is not a feature in manila18:27
bswartzwhat are you talking about18:27
ganso_bswartz: I am prototyping it, I created the blueprintt18:27
bswartzmigration is going to require all kind of changes18:28
bswartzmigration should use the RPC layer18:28
bswartzI thought you were talking about a snapshot mechanism that required mounting18:29
ganso_bswartz: exactly, with this prototype, I am trying to predict those changes, so far, I have not found anything bloocking18:29
bswartzmigration needs to work for all backends18:29
bswartzokay18:29
ganso_bswartz: no, no, I am implementing the generic migration approach18:29
ganso_bswartz: (not specific for generic driver)18:30
bswartzyeah we're saying the same thing18:32
bswartzmigration has to work for everything18:32
bswartzthus it should manage access using the manager RPCs18:33
ganso_bswartz: ok, so RPCAPI does not go to API, it goes to other backend's manager.py. Is it better to stick with that or find a way to go API?18:34
bswartzganso_: you're modelling this on the cinder approach, right?18:34
bswartzdon't use the REST API18:35
ganso_yes18:35
bswartzjust the RPC layer18:35
bswartzI've been wanting to propose a manila data-moving service18:35
bswartzwhich would be instrumental for a migration feature18:35
bswartzbut it's sort of a more fundamental problem to solve18:35
*** dustins has quit IRC18:36
ganso_bswartz: Yes, I am sorting out what type of problems and steps migration mechanism requires, the data-moving service would be a huge improvement to what I am prototyping]18:36
*** rushil has quit IRC18:37
bswartzthe problem we will face is that manila-share nodes may not have fast data access or even data access at all18:37
bswartzand may lack the right client bits for certain filesystem protocola18:37
*** dustins has joined #openstack-manila18:38
bswartzif we centralize all of the mounting and data moving into a single service, then we can document that that service needs to run on a fast-bandwidth node with good network access and all the client protocol drivers installed18:38
*** rcallawa_ has quit IRC18:38
*** vbellur has joined #openstack-manila18:38
bswartzand furthermore, that service can scale independently of the rest of the system18:39
*** rcallawa has joined #openstack-manila18:39
bswartzI don't like the idea of bottlenecking migration operations on the manila-share node18:39
ganso_yes, that would be an interesting discussion at the design summit. It is probably going to be the case where my prototype will be stalled until that service implemented, but I believe the concept will be able to be re-used18:40
bswartzthere's no reason not to proceed on a prototype -- I expect the code would be largely reusable18:40
bswartzjust don't polish it too much,and expect it to get refactored18:41
ganso_bswartz: yes :)18:41
