mkodererganso: ping12:29
gansomkoderer: pong12:29
mkodererganso: I have a questions to migration from one share_type to another12:33
gansomkoderer: sure, what is the question?12:34
mkodererganso: I think this can be very tricky for drivers since they have to implement for each capability what are the action that need to be performed12:34
mkodererganso: not sure if this is possible that easy12:35
*** bill_az has joined #openstack-manila12:35
gansomkoderer: indeed, it may not be that easy for drivers12:36
gansomkoderer: for fallback it is very easy since it always creates a new share and copies data over12:37
mkodererganso: yeah - you know I am not a big fan of the generic way ;)12:37
mkodererganso: for us only driver supported migrations look intressting to be honest12:37
gansomkoderer: for drivers that use replication or data migration mechanisms to migrate the share, when the driver notices that the value "share_type" of the new instance is different than the source, then it may have to do something completely different, like, not use any replication mechanisms, create a new share and copy data... thus being less effective (but12:38
gansostill most likely more effective than fallback)12:38
gansomkoderer: this may vary from vendor to vendor. For Hitachi, it does not affect at all12:40
mkodererganso: yeah it's depending on the driver capabilities12:40
mkodererbut it also mean the migrate api also support a retype action.. = different share_type but same host, backend and pool12:41
*** baojg has joined #openstack-manila12:43
gansomkoderer: yes, this was discussed at the midcycle12:45
gansomkoderer: we agreed to allow some properties to be changed during migration, like host, share_network, az, and share_type12:45

bswartzganso: what's up14:18
gansobswartz: Hey Ben14:19
gansobswartz: I was implementing the removal of 'complete' parameter from migration-start14:19
gansobswartz: so I stumbled across the possible need for backwards compatibility14:19
gansobswartz: right now microversion is planned to be 2.2014:19
bswartzwhy? it's experimental14:19
gansobswartz: we've had this discussion in the midcycle, some people mentioned that if it is not much effort, it is preferable to keep backwards compatibility even in experimental14:20
bswartzthe whole point of experimental is that we don't guarantee backwards compatibility14:20
gansobswartz: so this time is actually less effort to be backwards compatible than not to be14:20
bswartzexplain how it's less effort14:20
bswartzultimately we don't want this feature at all14:21
gansobswartz: yes, but when migration is not experimental anymore, then all backwards compatibility will be wiped, we are not there yet14:21
bswartzthe sooner we converge on the correct API the easier it will be to exit experimental14:21
gansobswartz: the feature is there, it has a default value. Basically in 2.20 I will be removing the code that reads the value, and the default value becomes False, instead of True. That's it14:21
bswartzthere's no reason to delay a change if we know we want it eventualy14:21
gansobswartz: we may want it back later, as we discussed in the midcycle. Although, it will be for sure removed if migration is not experimental anymore while the latest version does not include the 'complete' parameter, as we agreed14:24
bswartzthat's not how I recall things14:24
gansobswartz: sorry, as we discussed in the *weekly meeting last week14:25
bswartzI suggested that the non-experimental version of the API is 2 phase only, and in the future we could bring back 1-phase if there was a strong use case for it14:25
gansobswartz: exactly14:25
bswartzhowever to get to that place we need to make the existing API 2 phase only14:25
gansobswartz: yes, it is 2-phase only now, for 2.2014:26
bswartzand then we need to bless that API as non-experimental14:26
gansobswartz: prior to 2.20, it offers possibility to be 1-phase14:26
bswartzokay so then what are we talking about?14:26
gansobswartz: if I completely remove the code now for 2.20 (experimental), then 2.19 and prior to that will be broken14:27
gansobswartz: right now changing the default value achieves what we want14:27
gansobswartz: then, the patch to change it to non-experimental will be slightly bigger14:27
gansobswartz: because it will be removing the backwards compatibility code as well14:27
bswartzif the code can be left in without affecting the rest API, then why would be remove it later on?14:28
bswartzeither the code is harmless or it's not14:28
bswartzif it's harmless, we leave it in forever14:28
bswartzif it's not, then the sooner we remove it the better14:28
bswartzI really don't care about backward compatibility of an experimental feature14:29
bswartzin fact it might be good to make an example of an experimental feature that changes so people understand14:29
