vponomaryovhere I fix only LVM, because all other are affected without our configs11:16
vponomaryovthey are affected because of crappy config of devstack in CI in general11:17
vponomaryovthat, I guess, should be fixed, for example, here -> https://review.openstack.org/#/c/427561/11:17
gansovponomaryov: I am confused, why only LVM needs the fix?11:18
vponomaryovganso: lots of jobs need it11:18
vponomaryovwe redefine list of services explicitly only for it11:18
vponomaryovwhere we want to have nova working11:18
gansovponomaryov: oh, it is the only one redefining11:18
vponomaryovwe redefine it in other jobs too, but do not require nova11:19
gansovponomaryov: ok so It seems we will need both fixes to get gate working again11:20
gansovponomaryov: hum, generic is not voting anymore, so only LVM fix is required11:20

vponomaryovganso: we were talking with bswartz about it, and we had the same opinion that, for Ocata, we should just restrict migration for anything related to share groups16:49

gansobswartz: pong18:09
bswartzganso: I confirmed the issue w/ the LVM driver and revert, however fixing it will require unexport/reexport of the share itself18:10
bswartzganso: the export code for LVM is part of the nfs helper class, and that class needs some serious reworking IMO18:10
gansobswartz: are you saying it is not possible to be done without this reworking?18:11
bswartzganso: I would like to propose punting the actual bugfix for LVM to Pike and fixing the issue in ocata by removing the revert capability18:11
bswartzganso: it could be, but I'm not keen on it -- it would mean doing some throwaway work I think18:11
gansobswartz: we won't have revert on first party driver if you do so18:12
bswartzyes that represents a risk for testing of backports18:12
*** kaisers has joined #openstack-manila18:13
bswartzgiven that 3rd party drivers implement the feature though I'm fairly confident that if the feature does break due to a backport, we would still catch the issue18:13
bswartzalso, after it's fixed properly in Pike we can still consider backporting that fix18:13
*** makowals has quit IRC18:13
gansobswartz: I would try to avoid this situation as much as possible18:14
gansobswartz: backport a refactor?18:14
bswartzI'm just concerned about the risk of doing a rewrite of the NFS helper right before the release18:14
bswartzbasically I see 3 alternatives18:14
bswartz1) Fix it now and do the refactor later18:15
bswartz2) Fix it later and backport18:15
bswartz3) Fix and refactor now18:15
bswartz(3) is too risky, and I don't really like (1)18:15
bswartzthat's why I'm proposing (2)18:16
*** lpetrut has joined #openstack-manila18:16
gansobswartz: if we do #2 we would need to be very careful with that backport18:16
bswartzwe can still agree to do (1) but I'm not sure how gross it will get and how much effort will be wasted when we do clean up the helper later on18:16
*** makowals has joined #openstack-manila18:17
bswartzganso: what concerns you most about a backport?18:17
gansobswartz: how soon do you plan on fixing that in Pike? we should do this as early as possible... and how about a RC2?18:17
bswartzthe chance that the LVM driver's export code might stop working for Ocata?18:17
gansobswartz: we would need to keep all other backport changes at bay to avoid conflicts, a refactor is a big change to backport18:18
bswartzI would rather slip RC1 and not have RC2 at all18:18
gansobswartz: even if this is the only bugfix for RC2 and it is thoroughly tested?18:18
bswartznormally the way we handle bugs in RCs is that you either have to fix it in RC1 or punt to the next release18:19
bswartzthe only things that should merit an RC2 are bugs found between the time RC1 is cut and the actual release date18:19
gansobswartz: hummm... but this is a high priority bug18:20
bswartzotherwise we create a bad incentive for people to plan to fix their bugs between RC1 and RC218:20
bswartzganso: the bug can be "fixed" be removing the capability -- it's just that it creates a testing hole18:20
bswartzI'm arguing that the testing hole is not too serious because we have a plan to close it in pike, and we have adequate coverage in ocata18:21
gansobswartz: based on what you are saying, if we don't have time to fix it until tomorrow, we have to go with #218:21
bswartzboth of those points are debatable of course18:22
bswartzno I believe we have the option to do RC1 on friday, or monday, or whenever18:22
*** a-pugachev has quit IRC18:22
bswartzevery day the RC slips increases pressure to punt bugs to Pike though18:22
bswartzI can confirm this with our current release PTL18:23
